JOHN B. SI-IAFFER, OF MOUNT CARROLL, ILLINOIS.

GATEL SPECIFICATION forming part of Letters Patent No. 659,107, dated October 2, 1900.

Application filed January 20,1900- Serial No. 2,130. lllo model.)

To all whom it may concern:

Beit known that 1, JOHN B. SHAFFER, a citizen of the United States, residing at Mount Carroll, in the county of Carroll and State of Illinois, have invented new and useful Improvements in Gates, of which the following is a specification.

My invention relates to improvements in road-gates, and more particularly to the class of gates that can be opened or closed by a person on horseback or in a vehicle without having to dismount to do so.

The object of my invention is to provide a gate of this character which will be light and yet be strong enough and be easy to operate and at the same time cheap and durable.

In the drawings which accompany this specification and of which they form a part, Figure 1 is a side elevation of my gate closed. Fig. 2 is a plan view, partially in section. Fig.

3 is an end elevation, partially in section. Fig.

4 is a detailed view of the latch.

In the drawings like characters of reference denote like parts wherever they occur.

The superstructure for supporting the gate and operating mechanism pertaining thereto consists of frames A and B. Frame A is formed of uprights 1, resting on mud-sills 2, surmounted by cross-bar 3, with a suitable system of braces 4to add strength and rigidity to the structure. Frame B is constructed of the two-piece uprights formed of pieces 5,

footed on sill 6 and surmounted by cross-bar 7, J

and foot-braces 8, which serve as attachments for lateral members 9,which in turn form guides and provide supports for operating-levers. Pieces 10 complete the frame. The two inside ones, in connection with bolts 42, form guides for latch-strings, as will be hereinafter pointed out. A system of braces 11 connect frames A and B and tie the structure securely together.

Gate 0 is mostly of ordinary construction, but has some points of novelty. Horizontal boards 12, combined with vertical pieces 13, make the ordinary frame; but the top members 14 are prolonged backward. Said top members may be placed parallel or may be sprung out, as shown in the drawings, to pern1it lever-arms 35 to be interposed between the top members and the gate-frame. Blocks 15 15 are interposed between the top members, and rods 16 are secured to blocks 15 and to pieces 13. These rods form a guide for the latch-string when the gate is being opened. A lateral member 17 adds strength to the structure and prevents the splitting or bending of the members 14 during the process of opening the gate. The piece 17 is setat an angle sufficient to allow the gate to clear block or sill 18, placed to serve as a support for the gate when open and to prevent its cutting into the ground.

Pivoted to posts 1 on pintles 20 are arms 19 which extend downwardly and are pivoted on pintle 21, which extends through the ends of members 14. These arms play an important part when the gate is opened or closed.

Gate-post D is made of vertical posts 22,

footed on sill 23 and supported by braces 24.

Strip 25 and latch-block 26, interposed between posts 22, complete the structure.

Latch E consists of a bar with notches 27, 28, and 29 cut therein and weights 31 mounted thereon. Notch 27 limits the forward movement of the latch when the gate drops into position closed, and notch 29 limits themotion of the latch, and beveled notch 28 enables the latch to be operated by the latch-string and also allows the latch to slide into locking position by gravity and engage pin 28. The weights 30 31 add mass to the latch, and thus insure its operation. Pins 28 form guides for the latch.

I will now describe the operating mechanism of my gate.

The levers 32 are pivoted on the pintles 33 and are pivotally connected to the rods or links 34. These rods 34 extend downwardly and forwardly and are pivotally connected to the lever-arms 35. The lever-arms 35 are in turn pivoted on pintles 36 at their upper ends centrally to the gate and are reversely pivoted to the frame B on the pintles 37. A latch-string 38 is attached to the latch E at 39 and extends upwardly between the guides 16 and branches at 40 and passes each way through the guides 41, formed by the bolts 42,and extends alongthe levers 32 and through the holes 43. Said latch-stringis fitted at the ends with hand-bars 44 and also provided with the stops 45 to limit its movement.

The operation of my gate is as follows: The person desiring to pass through the gate rides IfO up and grasps one of the bars 44 and gives it a gentle pull. The latch -string 39 yields easily, and because of the sloping notch 28 draws the latch backward from between posts 22 and from under latch-block 26, and the stop 45 is brought in contact with the lever 32. A harder and sharper pull is then given, and the gate is raised upward by arms and swings backwardly, suspended on arms 19, and on passing the center drops by gravity into position, resting on block 18. The person then rides through the gate, approaches the other hand-bar, grasps it, and bya firm jerk closes the gate.

Having thus described my invention, What I claim is- 1. Agate havinga rearwardly-extended top rail, a diagonal member secured to the rear end of said top rail and to the bottom member of said gate, a pair of pivoted links connected at their lower ends to the rear end of said top rail and reversely connected to a framework, an additional pair of pivoted links connected at their upper ends to said gate, near the top, and about the middle, said additional links being reversely connected at their opposite ends to a support or framework, and gate-actuating levers linked to said additional links, substantially as described.

2. A gate having a rearwardly-extended top rail, a pair of pivoted links connected at their lower ends to said top rail at its rear end and connected at their upperends toaframework, a second pair of pivoted links connected at their upper ends to said gate, about its middle and near the top, the opposite ends of said links being reversely connected to the framework, a latch, a latch-string connected to said latch and having two branches extending each way through pulleys or guides and passing through holes in the gate-actuating levers, stops on said latch-string to limit its motion, gate-actuating levers linked to said second pair of links, substantially as described.

3. The combination of a framework consisting essentially of four posts, a gate having a rearwardly-extended top rail and a diagonal member attached at its upper end to the rear end of said top rail and at its lower end to the bottom member of said gate, a pair of pivoted links connected at their lower ends to the rear end of said top rail, and attached at their upper ends to the rear posts of said frame, a second pair of links pivotally connected at their upper ends to said gate, near the top and about the middle thereof, said links being reversely pivoted at their opposite ends to the forward posts of said frame, and means for actuating said gate, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN B. SHAFFER.
