DAVID ANDREW ASKEW, OF COLERAINE, NORTH CAROLINA.

AUTOMATIC STOCK-FEEDER.

SPECIFICATION forming part of Letters Patent No. 641,920, dated January 23, 1900.

Application filed May 31, 1899. Serial No. 718,856. (No model.)

To whom it may concern:

Be it known that I, DAVID ANDREW ASKEW, acitizen of'the United States, residing at Coleraine, in the county of Bertie and State of North Carolina, have invented a new and useful Automatic Stock- Feeder, of which the following is a specification.

The invention relates to improvements in automatic stock-feeders.

The object of the present invention is to improve the construction of automatic stockfeeders and to provide a simple and comparatively inexpensive one adapted to permit feed to be readily placed in the troughs at any time and without entering the stalls and capable of preventing the animals from obtaining access to the feed until a predetermined time and of automatically opening the feed-troughs at such time.

The invention consists in .the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of an automatic stock-feeder constructed in accordance with this invention. Fig. 2 is a vertical sectional view taken longitudinally of two of the stalls. Fig. 3 is an elevation of the head of one of the stalls, partly broken away to illustrate the arrangement of the means for operating the hinged lids or covers. Figs. 4 and 5 are detail views illustrating the construction of the tripping mechanism. Fig. 6 is a plan view of the mechanism for setting and tripping the rock-shaft.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 1 designate parallel series of stalls arranged head to head and separated by an intervening space 2, which forms a passage-way for the operator and which affords access to the feed-troughs 3 to enable the feed to be supplied to the same, as hereinafter described, without entering the stalls. Arranged over the space or passage 2 between tlie series of stalls is a horizontal rock-shaft 4E, journaled in suitable bearings. and provided opposite the corresponding stalls of each series with. oppositely-disposed arms 5, which are connected by cords 6 or other suitable flexible connections with catches 7 for holding hinged lids or covers 8 of the feed-troughs closed, and the rock-shaft is adapted to be rotated to unfasten the catches. The arms 5 are preferably t'ormed integral with sleeves 9, which are adj ustably secured to the horizontal rockshaft by clamping-screws 10 or other suitable fastening devices.

The rock-shaft is actuated by a weighted arm 11, adjustably mounted on the rock-shaft by means of a sleeve 12 and a clamping-screw 13 and arranged nearly in a vertical position when the parts are set, as illustrated in Fig. 2 of the accompanying drawings, in order to relieve the tripping mechanism of strain.

The weight 14 of the actuating-arm 11 is adjustable by means of a clamping-screw 15, and it is adapted to move inward and outward on the arm to vary the power of the same. v

The rock-shaft is provided with a settingarm 16, which is engaged by a reciprocating springactuated catch 17, and the latter is adapted to be tripped by the alarm mechanism of a clock 18, as hereinafter described. The arm 16 is adjustably mounted by a setscrew 19 in a socket 20 of the sleeve 21,which is secured to the rock-shaft by a clampingscrew 22, and the outer end of the settingarm 16 is beveled, as clearly illustrated in Fig. 4 of the accompanying drawings, to enable it to engage the reciprocating catch antomatically when the rock-shaft is rotated by hand, as hereinafter described, for setting the mechanism for automatic operation.

The clocklS, which is mounted on a suitable support, is provided with a pinion 23, which is connected with and adapted to be rotated by the alarm mechanism of the clock, so that the clock may be set at any time for tripping the reciprocating spring-actuated catch. The pinion 23 meshes with a large gear-wheel 24, which carries a tripping-arm 25, and by employing the small pinion and the large gear-wheel suflicient power is obtained from an ordinary clock to operate the mechanism. v

The arm 25, which is radially disposed, is adapted to engage the upper portion of a lever 26, which is fulcrumed near its lower end at 27 on a suitable support 28, and its lower end 29 is slotted and is pivoted by a pin 30 ICO to the reciprocating spring-actuated,bolt 17, which is mounted in suitable guides or ways and which has its beveled engaging end arranged in the path of the setting-arm of the rock-shaft. \Vhen the radial arm oscillates in the direction of the arrow in Fig. 4, the lower end of the lever 26 is swung inward, thereby withdrawing the bolt or catch 17, which releases the arm 16 and allows the weight to actuate the rock-shaft. The settingarm is beveled at its lower face, and the spring-actuated bolt or catch 17 is beveled at its upper face, and when the setting-arm is swung downward by hand it engages the catch or bolt automatically. The reciprocating catch or bolt is provided with a slot or recess to receive the lower end of the lever 26, and its rear end is reduced to form a stem on which is disposed a coiled spring 31. The spring 31 engages the shoulder formed bythe reduction of the rear portion of the bolt and bears against a guide 32, and it is adapted to return the bolt or catch to its normal extended position after the operation of the tripping mechanism.

The actuating-arm 11 of the rock-shaft is provided at its outer end with an eye 33, to which is attached one end of a cord 34 or other suitable flexible connection, which extends over a pulley 35, located at a point above the rock-shaft, and when the cord 34 is pulled upon the weighted arm of the rock-shaft is swung upward to the position illustrated in Fig. 2 of the accompanying drawings. The upward and downward movement of the weighted arm of the rock shaft is limited by upper and lowerstops 36 and 37, adapted to relieve the rest of the mechanism of strain.

Each feed-trough is divided by a partition 37 into two compartments 38 and 39. The compartment 38 remains open at all times, being uncovered, as clearly illustrated in Fig. 1 of the accompanying drawings,and the other compartment 39 is covered by the hinged lid or door 8 when it is desired to prevent access of the stock to the same. The two compartments are provided for the purpose of facilitating the feeding of stock at both night and in the morning, the feed to be supplied in the morning being placed in the covered compartment 39, so that the stock will not have access toit until the compartments are opened by the automatic device, which may be set for any hour, thereby enabling stock to be fed at an early hour in the morning without requiring the attendance of the operator.

The hinged lid orcover 8, which is arranged at an inclination when closed, as clearly illustrated in Fig. 2 of the accompanying drawings, is provided at its outer or free edge with a laterally-extending arm 40, which is arranged to operate in a suitable guide or way 41 and which is engaged by the catch 7 when the lid or cover is closed. The curved guide or way 41 is formed by a board or partition 42 and a curved strip 43, constructed of any suitable material. The edge 44 of the partition 42 is spaced from the curved strip 43 of the stall and is curved, and the partition is separated from the adjacent side of the stall to house the operating mechanism and to prevent the stock from coming in contact with the same. The ropes or cords 6, which extend from the rock-shaft in opposite directions, pass over guide-pulleys 45 at the upper portion of the heads of the stalls and extend downward over guide-pulleys 46 and under guide-pulleys 47. The guide-

pulleys

46 and 47 are arranged within the housing or casing at one end of the feed-trough, and the lower ends of the flexible connections 6 are secured to the spring-actuated bolts of the catches 7, and when the rock-shaft is rotated the bolts are withdrawn from engagement with the arms 40, and the lids or covers are swung upward by the means hereinafter described. The bolts of the catches 7 are beveled at their upper faces, and the arms 40 are beveled at their lower faces, as clearly shown in Fig. 2 of the drawings, to enable the lids or covers to engage the catches automatically when they are swungdownward. The lids or covers are drawn downward by the operator and are connected with cords or ropes 48, preferably forming continuations of the cords or ropes 6 and extending from the arms 40, beneath guide-pulleys 40, through the heads of the stalls, and their outer ends are preferably attached to the same, as illustrated in Fig.2, to prevent them from touching the floor.

Each lid or cover 8, which is connected by hinges 50 to the head of the stall, is opened by a weight 51, operating in a suitable well 52 and connected with one end of a cord or rope 53, which passes over a guide-pulley 54 and which has its outerend attached to the lid or cover at the free edge thereof, preferably by being secured to the arm 40. As the lid or cover is arranged at an inclination when it is closed, it will require a considerable pull on the cord or rope 53 to start the lid or coverin its opening movement, and in order to enable a comparatively light weight to be employed to open the troughs the opening movement of the lid or cover is started by means of aspring 50, which is adapted to lift the said lid or cover to a horizontal position, so that the weight may readily act on the same. The spring 50, which is preferably constructed as illustrated in Fig. 1 of the accompanying drawings, is shown consisting of a central substantially U shaped loop 51,side coils 52, and arms 53. The loop 51 is secured to the upper face of the lid or cover by staples or other suitable fastening devices, and the arms 52 are similarly fastened to the head of the stall. \Vhen the lid or cover is open, it is arranged within a beveled frame 54, consisting of vertical and horizontal bars mounted on the stall and adapted to prevent the stock from closing or attempting to close the lid or cover, and the said frame by being arranged around the lid or cover causes the parts to present smooth surfaces to the stock.

Each stall is provided at its head with a downwardly-swinging or drop door 54*,hinged at its lower edge and secured when closed by a pivoted button 55, arranged to engage the upper edge of the door. This drop-door affords access to the feed-trough from the passage-way between the stalls and enables the feed to be placed within the trough without entering the said stalls. By this construction children and timid persons may be employed for handling the feed without liability of being frightened or injured.

It will be apparent that the apparatus,which is simple and comparatively inexpensive in construction, is positive and reliable in operation, that it will enable feed to be placed in the troughs at any desired time, and that it will prevent access of the stock to the contents of the closed or covered troughs until it p is desired to feed the animals. It will also be apparent that the troughs, which are provided with two compartments, maybe sup plied with feed for night and morning and that the closed or covered compartments may be opened at any hour in the morning or other times without requiring the attendance of the operator. Furthermore, it will be apparent that by the drop-doors at the back of the stalls the feed may be placed in the troughs without entering the stalls, thereby enabling children and timid persons to be employed for this purpose without danger. The weight of the actuating-arm may be readily adjusted to provide the necessary power for releasing the catches, and the setting-arm of the rockshaft may be adjusted longitudinally to enable it to be positively released by the thro of the lever 26.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
