This invention relates generally to milking plants andin particularto a milking plant in which the cows are prepared for milking and milked in successive groups while headed in the same direction through the plant. An object of this invention is to provide an improved milking plant. A further object of this invention is to provide a milking plant in which a passageway for taking cows in single file order is comprised of a series of longitudinally spaced, but closely adjacent, sections. Doors or partition members at the ends of the sections are linearly movable to divide the passageway into separate stall units corresponding in number to the. sections thereof. Still another object of this invention is to provide a stall unit which is of a width and adjustable as to length so that acow therein is substantially restrained against sidewise and back and forth movement during a milking operation. Yet a further object of this invention is to provide a milk plant in which a pair of cow passages or lanes are arranged in a parallel spaced relation, with the floor surfaces thereof at a higher level than the fioorsurface therebetween to facilitate handling, of the cows in the passages. Each passage is longitudinally divided into sections, with each section being of a length to accommodate a cow therein. Movably supported on the sections are door members for closing the ends thereof. With a door at one end of a passage closed, the cows are moved in single file order into the passage from its other end, in number, corresponding to thesections in the passage. The remaining doors in the passage are then closed-to confinethe cows in separate stalls, as formed by the closed doors. Afterthe cowsare milked, the doors are opened and=the cows, while headed in the same direction, are moved from the passage. Still another object of this invention is to provide a milking plant capable of efiiciently handling large or small breeds of cattle, adapted to be ,used with milkermachines of pail, portable orcombine type. and of a construction such that it can be installed withina relatively small floor space. A feature of this invention is found in the pro,- vision of a milking plant in which a cow passage is comprised of a series of open ended stall units arranged end to end. Upright door members are movably supported at, the ends of the stall units such that, the adjacent ends of the stall units have, a common door member. The doors are movable transverselyof thestall units from positions across the passage to positions projected laterallyoutwardly from a side of the passage. As a result agroup of cows may be driven. into the passage from one end, and then confined within the passage for milking by closing the doors. When milking is completed, the doors are opened and the cows moved in the same directionout of the passage to make room for a second group of cows. Further objects, features and advantages. of this invention will appear from the followingdescription when taken in connection with the accompanying drawing, in which: Fig. 1 is a sideelevational view of the milking plant of this invention; Fig. 2 is a sectional view as seen along the line 2-2 in Fig. 3; Fig. 3 is a plan view shown in Fig. 1; Fig. 4 is an enlarged fragmentary detail perspective assembly view of a door member and its supporting means, which assembly forms par of the milking plant of this invention; Fig. 5 is an enlarged detail sectional view as seen along the line 5-5 in Fig. 1; and Fig. 6 is a longitudinal sectional view of a side member forming part of a stall unit. With reference to the drawings, the milking plant of this invention is illustrated in Figs. 1 and 3 as including a pair of cow passageways or lanes, indicated generally at H), arranged in a spaced parallel relation. The bottoms or floor surfaces llfof the passageways l0 (Fig. 2) are at a hlgherglevel than the floor surface l2 between the passageways, so thata trough I3 is formed between the passageways'for a purpose to appear later. Since the passageways I!) are of a like construction, only one thereof will-be described in detail, with similarnumerals being applied to like parts. A passageway I0 is comprised of a series of sections or stall units, designated generally at [4 (Figs. 1 and 2), arra'nged end to end in a straight row. Each stall unit l4. includes a pair of end frame members l6.of a; tubular construction and of an arch or inverted U shape having uprightlegs l1 and an upper connecting base portion l8. Each pairof end members i6, for a stalll4, are connected together by adjustable side members l9 (Figs. 1 and 6), also of a tubular construction, with each side member l9 comprising a pipe, section 2| which is in telescopic engagement within a pipe section 22. The outer ends 23 and 24 (Fig. 6) of the pipe sections 2| and 22, respectively, are secured within connections 26 of T-fittings Z'Lwhich. are slidably supported for vertical movement about of the milking plant the legs I! of the end members it. The side members 19 are releasably maintained in vertically adjusted positions on the leg members IT by the provision of friction screws 28 (Figs. 1 and threadable within the T-fittings 21 for frictional engagement with the end member legs 17. The stall units 14 are closed at their opposite ends by means including upright partition members or doors 3!, the upper ends of which (Fig. 4) are provided with a pair of laterally spaced roller assemblies, indicated at 32, ridable within a track member 33 of a substantially inverted channel shape having inwardly projected track portions 34 at the. free ends of its leg sections 36. At longitudinally spaced positions on the top side of the track member 33 are a pair of attaching brackets or straps 3'! (Figs. 3 and 4), which are secured to the base portion IB of an end member I6 by bolts or the like 38. As best appears in Fig. 3, the track members 33 are of a length greater than the transverse dimension of an end member it so that a door 35 is movable to a first position extended across an end member Hi, to close a stall unit l4, and to a second position projected laterally outwardly from an end member it, to open a stall unit It, as illustrated for the doors 3| in Fig. 2. In order to releasably hold a door 3! in either a closed or open position, the track portions 34, at positions spaced inwardly from the ends thereof, are formed with oppositely arranged recesses or notches 39. Thus on movement of a door 3! to an open or closed position, the roller assembly 32 leading in the direction of movement of the door 3|, drops within the notches 39 to define a desired moved position. In the installation of the milking plant of this invention, the end members. I 6 for each stall unit l4 are spaced a distance apart depending upon the breed of cattle to be milked. In other members 19. The adjustment of the side members l9 vertically of the legs I! on the end members i6 is such as to provide ready access of the milking plant operator to a cow from the side of a stall unit, and a side guard to prevent a cow from kicking'laterally outwardly of a stall. The stall units l 4, including a pair of end members l6 and associated side members l9, are then assembled end to'end, and in a permanent relation, by setting the lower ends of the legs I! within the concrete floor surface I I. To eliminate any unnecessary spreading of cow manure, dirt and the like throughthe milking plant, it is contemplated that each floor surface I l form a passageway 10, and as illustrated in Fig. 2, be formed with a pair of oppositely arranged upright proj e'ctions or walls 43 which extend continuously o'ver the full length of the passageway Ill. The legs I! may then be set within the walls 43 so as to extend upwardly therefrom. "The adjacent end frame members is of the stall units M are spaced a distance apart to provide for the location therebetween of a movable door 3| and its supporting track member 33. Since this spacing is only on the order of about five inches, it is seen that with the doors 3| moved to their open positions, the side members [9 form a substantially continuous confining passageway for cows in single file order. With reference to Fig. 3, it is seen that each of the end members It for the end stalls indicated as [4a is provided with a track 33 and door 3|, and that the oppositely arranged stalls, indicated at M, have a track and door assembly carried on only one of their end members l6. As a result, the adjacent ends of the stalls l4 and Ma have a common door and track assembly. Although in Fig. 3 each passageway I0 is illustrated as including only a pair of stalls l4, it is to be understood that any number of stalls may be used. Further, it will be noted that the stalls arranged at opposite sides of the trough l3 are in a staggered or longitudinal offset relation to provide for a clearance relation of the doors 3! to positions within the trough I3. A door 31, located between the adjacent ends of the stall units !4 and [4a is limited against swinging movement laterally of its associated track 33 by the engagement of the lower end of the door with the legs i! of the adjacent end frame members It. The doors 3| at each end of a passageway iii are limited against lateral swinging movement by the provision of upright stop members 44 set in the wall portions 43 of the floor I I at a position spaced outwardly from the legs I! of the outer end frame members IS. The rows of stall units [4 are spaced a distance apart such that the trough i3 is of a width to conveniently accommodate the type of milker machine (not shown) to be used, and to give ample working space for the machine operator. For the installation shown in Fig. 3, the over-all width of the trough l3 and passageways I0 is about nine feet, with the length necessary to accommodate the stalls longitudinally being about fifteen feet. Ramps for the passageways ID are indicated at 46. In use, and with reference to Fig. 3, assume that the cows are to be moved in single file order into the passageways it! over the ramps 46. The end doors indicated at Zia are then moved to their closed positions and the remaining doors iii are moved to their open positions. Two cows are then driven into each passageway 40, and the doors 3| are moved into their closed positions whereby to separately confine a cow within each section or stall unit l4 of a passageway it. The cows in one passageway Ill are then prepared for milking, and the milking machine applied thereto. While this first set or group of cows are being milked, the second group of cows in the other passageway It! are prepared for milking. On the completion of the preparation of the second group of cows for milking, the first group of cows has been milked. The milking machines are then transferred from the first group of cows to the second group of cows, and the first group of cows are turned out and a third group brought in and prepared for milking while the second group is being milked. In this manner, and after the first group of cows has been prepared for milking, there is a continuous succession of milking operations with a resultant saving in time and, efiiciency. Tomove a group of cows from a passageway IE, it is only necessary to open all of the doors 3i, and with the cows headed in the same direction as when they entered the passageway over a ramp 46, they are moved froma passageway end, indicated at 50. From the above description it is seen that the invention provides a milking plant which is of a simple and compact construction, capable of application to the milking of small and large herds, and adapted to be readily installed within a relatively small floor space. Further, the construction of the sections or stall units of a cow passageway is such as to provide for their economical manufacture, shipping and storage in a nested relation, and assembly for use by an un skilled workman. Although the invention has been described with respect to a preferred embodiment thereof, it is to be understood that it is not to be so limited since changes and modifications can be made therein which are within the full-intended scope of this invention, as defined by the appended claims.
