GATE.

SPECIFICATION forming part of Letters Patent No. 643,147, dated February 13, 1900. Application filed March 1, 1899. Serial No. 707,267l (No model.)

T0 all whom t may concern:

Be it known that I, DAVID MILLER, a citizen of the United States, residing at Garden City, in the county of Cass and State of Missouri, have invented a new and useful Gate, of which the following is a specification.

The invention relates to improvements in gates.

One object of the present invention is to improve the construction of j ump-gates, more especially that shown and described in Patent No. 603,793, granted to me May 10, 1898, and to increase the strength, durability, and efficiency of the same and lessen the cost of construction.

A further object of the invention is to prevent the gate from being opened by hogs and to provide a device which will engage the gate automatically and lock it against movement should it be subjected to lateral strain by reason of stock pressing against it.

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 a gate constructed in accordance with this invention and shown closed. Fig. 2 is a side elevation, partly in section. Fig. 3 is an enlarged detail perspective view illustrating the construction of the keeper.

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

l designates a jump-gate constr-ucted ot" any suitable material and preferably consisting of a rectangular frame of tubular metal and a body portion of woven wire, as clearly shown in the accompanying drawings. The gate is supported by front and rear oscillating bars 2 and 3, arranged in pairs, as shown, and preferably constructed of tubular metal. Each pair of oscillating bars is provided at the upper terminals of its members with couplings connected by ashort transverse piece or vconnecting portion 6, which is arranged in a suitable eye or bearing of the gate. The lower terminals of the front oscillatingv bar are preferably branched or split, and the lower terminals of both oscillating bars are pivotally connected by suitable transverse fastening devices to a supporting-frame consisting of a horizontally-disposed U-shaped base a and oppositely-inclined U shaped standards or members 5 and 6.

The lower ends of the sides of the U-shaped standards or members 5 and 6 are secured to the horizontal bottom piece, and their upper portions are crossed, as clearly illustrated in Fig. 1 of the accompanying drawings, and are connected at such points by bolts 7 or other suitable fastening devices, which form the pivots or fulcrums for a pair of counterbalancing-levers 8,which are interposed between the sides of the U-shaped standards or members 5 and 6, the rearwardly-disposed standard or member 6 being narrower than the front standard 5 and arranged within the same.

The counterbalancing-levers,which extend forward and rearward from the supportingframe, are fulcru med between their ends and are provided with eyes or bearings formed by supplemental tubular pieces 9, secured to the levers, as shown. The front ends of the levers are curved upward at 10 and are connected by short chains 11 with lifting-rods 12, connected with the front inclined bars 2 and adapted to exert a direct upward pull on the same. The rear portions of the levers are bent at substantially right angles to form arms 13, to which weights 14 are connected, and when the levers are oscillated the weights swing upward and downward and serve to cushion the fall of the gate.

The gate is moved by means of operatingropes 15, connected with the gate at the point of attachment of the front oscillating bars and extending therefrom to pulleys 16 of the standard or member 6 and then passing away from the gate, at opposite sides thereof, to suitable uprights or supports 17, which .are provided with arms 18 and pulleys 19. The outer ends of the operating-ropes are provided with weighted handles 20, and when they are pulled upon the gate is moved 1ongitudinally with a jumping motion.

ner portions of the operating-ropes are connected with a pivoted latch 21 by a suitable connection 22, and this latch 21, which has its front end 23 pivoted to a central bar 24 of IOO Ass

the gate, is provided at its opposite end with a notch or recess 24, adapted to engage a projection or lug 25, extending inward from one of the front oscillating bars. The pivoted latch locks the gate in its closed position and is readily released when the operatingropes are drawn taut, and in order to hold the latch in engagement with the lug or projection which forms a keeper a coiled spring 22a is disposed on the rod, which forms the lower portion of the connection 22. This coiled spring 22a, which draws the operatingropes downward, is suitably connected with the gate. y

When the gate is closed, its front end is arranged between a pair of horizontally-disposed hook-shaped arms or projections 26 of akceper 27, which is mounted on a latch-post 28, and these arms or projections 26, which are formed integral with an attachment-plate, are spaced apart and lie at opposite sides of the end bar of the gate in position for the hooks, which project toward each other, to engage and embrace the same should the said gate be subjected to a lateral strain by stock pressing against it.

The gate is provided at its rear end with a vertical bar 27a, pivoted at its lower end to the bolt at the bottom of the front oscillating bars and connected at its upper end bya horizontal bar 30 with the bolt 3l, which connects the lifting-rods with the oscillating bars 2. When the gate is shut, the vertical bar 27a serves to close or obstruct the space at one side of the gate or between the standard 5 and the rear bar of the gate, and this prevents the stock from passing around the innerend of the gate while the gate is closed. When the gate is thrown open, said vertical bar drops back out'of the way, as shown in dotted lines in Fig. 2. One vertical bar is ordinarily sufficient and is placed on that side of the gate which is next to the fence, the latter extending as far out as the rear end of the gate when closed to prevent passage of the stock.

The invention has the following advantages: The gate, which is simple and comparatively inexpensive in construction, possesses great strength and durability and is easily operated. The counterbalancing-levers, which are disposed longitudinally of the gate, counterbalance the same and prevent the gate from straining or upsetting the supporting-frame. The operating mechanism is not liable to freeze and become inoperative in cold weather, and the gate is securely lockedA when closed and cannot be opened by hogs or other animals.

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.

What is claimed is- 1. The combination of a gate, oscillating bars supportingthe same, asupporting-frame comprising a horizontal or base piece, and the oppositely-inclined standards or members crossed at their upper portions, counterbalancing-levers disposed longitudinally of the gate and fulcrumed on the supporting-frame, and operating mechanism connectedwith the gate, substantially as described.

2. The combination of a gate, oscillating bars supporting the same, a frame comprising the oppositely-inclined standards 5 and 6 having their upper portions crossed, and a horizontal base connecting the'lower ends of the standards, longitudinal counterbalancin g-levers fulcrnmed on the standards at their point of crossing, and connected at their front ends with the oscillating bars, pulleys arranged at the top of the standard 6, and operating-ropes passing over the pulleys and connected with the gate, substantially as described.

3. The combination of a jump-gate, oscillating bars supporting the gate, a latch pivoted to the gate and interlocking with one of the oscillating bars, and operating mechanism connected with the gate and with the latch, substantially as described.

4. The combination of a jump-gate, an oscillating bar, a latch pivoted to one of the parts and engaging the other, and means for releasing the latch and for actuating the gate, substantially as described.

5. The combination with a longitudinallymovable gate, of a keeper comprising arms located at opposite sides of the gate in position to engage the front bar thereof when the gate is subjected to a lateral strain, said arms being provided with hooks which project toward each other in position to embrace the end bar of the gate, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

DAVID MILLER.
