To a. whom it may concern:

Be it known that I, GEORGE H. AYLWORTH, ofBrightom'in the county of Macoupin and- State of Illinois, have invented a certain new and useful Improvement in Gates, of which I the following is a full, clear, and exact de- .scription,1refe rence being had to the accompany ng drawings, forming part of this specification. -I

The subject of my present invention is an at-- tachment or improvement applicable to the cord operated gate described in Patent No.

' The subject of my present improvement is to provide against injury to thegate'by slam-j grantedto me the 6th of January,

. ming, either by the wind, or by careless hand ling. To this end I apply a spring either to? the free endofthe gate, or to the gate post, as hereinafter described, to take up'the concussion and; arranged to permit the closing of the gate by the operation of the latch by means of the cord, as hereinafter described.

In the accompanyingdrawings:Figure I is a perspective view of my improved gate, with the anti-slamming attachment. Fig. 1

.is a detail section, illustrating the movement of the take-up weight and cord. Fig. II is an elevation'son a larger scale of the latch end of the gate and the gate post. Fig. 111 is a face view of the gate post, showing the latch in transverse section, on line III-III, Fig. II, and omitting' the spring. Fig. 1V is a face view of the gate post and of the spring, showing the gate latch and spring attachment in section on the line IV=IV, Fig. II, showing the position when the gate is closed. Fig. V

is a View of the same, showing the action of the springcarried by the gate, when the gate is arrested thereby, in the act of closing. Fig. VI is an end view of the gate. Fig. VII is a face view of the gate post, showing the spring applied thereto instead of to the gate.

The main operating parts of the gate are as described in my Patent No. 444,325, above referred to.

1 represents the hinge post of the gate, 2 the latch post-,and 3'the gate proper, hung to the post 1 by' hinges 4, 4. Y

5 is a latch, pivoted at 6 to the gate3, andextending. through a vertical slot in the end piece 7.

arrest the movement of the latch, unless it is I lifted as hereinafter described.

"12 represents a sliding and swinging stop piece, which passes through a slotin a'bracket 13 secured to the latch post 2., The stoppiece 12 widens at the lower end 15, and has at the upperend a head 16, which normally-rests upon the top of the bracket so that thestop piece 12 hangs .in vertical position, and its lower end covers the recess 9 in thekeeper,

asshown in Figs. III, IV and V. .The stop I piece 12 has alimited swinging movement in either direction. to the extent ,indiczttedby dotted lines in Fig. III, so that when thelatch is lifted to escape the vertical abutment 11,

on either side of the keeper 8, the said latch coming in. contact with the swinging stoppiece presses it to the position shown in dotted lines, and can then. drop into the recess 9 of the keeper, permitting the. slot piece 12 to fall 'backinto its normal, vertical position, where it rests while the gate remains closed." This operation is nearly the same as described in my previous patent, and so is the opening operation by which the latch 5,,being lifted, slides the swinging stop piece '12 upward, in a vertical line, until the latch can. escape from the recess 9, when the gate swings ope'n, and is caught by one of the side posts 37.. The

latchis operated by the following means, differin g butslightly from the mechanism shown and described in my previous patent: A wire The cords 20 and 21, pass ,over carrying sheaves 23, suspended from horizontal; arms 24 on the fulcrum posts 30', and thence down the weight case 31, and around afsh'eave 25,

i from which is suspended a weight 26, (Fig. 1

. which rises and falls in the casing 31, so as to From the sheave 25, the cord or 21 extends upward around another sheave 28, suspended from the arm 24, thence horizontally around a sheave 29 at the extremity of said arm, from whence it depends and it is provided at its lower end with a handle 32. Fixed stops 33 on the depending cords limit the running of the same backward through the sheaves 29, when the cords are released, and the weight 26 descends to take up the slack.

37 represents the posts against which the gate is swung open in either direction, having catches or keepers 38 to retain the gate.

A gate constructed as above described, and operating substantially in the manner described in my former patent above referred to is liable to swing shut with too great violence in careless handling, or when blown to by the wind. To obviate this difficulty, and prevent any injurious effects from slamming of the gate, is the object of my present improvement. For this purpose I employ a V-shaped spring 39, the two arms of which project upward, with an outward inclination, and are united at bottom by a hinge connection 40 with the outer face of the latch bar 7, or end piece of the gate. The hinge connection 40 may consist of a simple shaft stud, with two heads, or a pair of washers between which the lower end of the V-spring' 39 is clamped, so as to allow it to turn upon the end bar 7 of the gate, to a limited extent. Its'upper end is controlled by a curved, operating rod 41, having a horizontal loop 42 in its extremity, which embraces the vertical arms of the spring, limits their spread and also the distance to which they can spring outward away from the outer face of the gate, as illustrated in Figs. II and IV. The curved, operating rod 41 passes over a roller 42 in the end bar 7 of the gate, and is connected at its upper end to a loop 43, inclosing the latch 5, to which loop 43 the vertical rod 18 is connected for operating the latch. The fixed keeper 8 is provided on its face at each lower corner with a horizontally proj ecting fixed stud 44, for receiving the impact of the spring when the gate swings to without the latch being raised. 1

. The operation of my gate, as now improved, is as follows: On approaching the closed gate, the driver desiring to openthe same, grasps the handle 32 of the pendent cord 20, or 21, as the case may be, and pulls the same, the first effect of which is to raise the weight 26 within the casing 31 until this movement is arrested by the stops 27. The cord, running through the sheaves 29, 28, 23 and 22, draws the rod 19, thereby operating the bell-crank lever 18, and-through the vertical rod or wire 17, lifting the latch 5, and at the same time, through the medium of the curved connecting rod-41,.drawing the spring 39 against the face of the gate out of reach of the studs 44, between which it rests, while the gate is closed. Thecontinued draft of the cord then,

through the agency of the beam 26,turns the gate on its hinges in the required direction, allowing the team to pass through. This done, the second handle 32 on the departing side of the gate is drawn down, and the gate is closed by the same operation. If the gate be closed with ordinary care, and the wind does ,not blow hard, very little service is required of the spring 39. If, however, the cord is released before the closing of the gate, allowing it to slam, or if the gate is caught by a strong wind, the spring 39 resting in its outer position, a short distance away from the outer bar 7of'the gate, as shown in Fig.

II, will strike one of the fixed studs 44 of the keeper 8, and bending, as illustrated in Fig. V, will take up the concussion and prevent slamming of the gate; Thegate will rest in this position, partially closed, until the latch 5 is lifted by means of the pull cord, which, through the medium of the curved connecting rod 41, draws the spring 39 into contact with the face of the gate, beyond the reach of the studs 44, as already described. Thela-tch 5 being at the same time lifted above the vertical abutment 11, comes in contact with the swinging stop piece 12, which swings aside to the position shown in dotted lines, which permits the latch 5 to drop into the recess 9 of the keeper. the spring arms 39 to spring outward between the two studs 44, 44, where they rest, as shown in Fig. IV.

' Substantially the same operation is produced by the modification represented in Fig. VILwhere the V-shaped spring 39 is applied to the face of the latch post 2, instead of to the gate. with one of the arms of the spring, deflecting it so that the spring takes up'the concussion, on the same principle already explained. When the latch 5 is lifted, to close the gate properly, it is carried above the end of the spring, and at the same time above the abutment 11, and permitted to fall into the recess 9, as explained. Similar springs are applied to the side posts 37, by which the gate is held open.

I claim as my invention 1. In combination with a cord operated gate, a V-shaped spring 39, operating substantially as herein described, to take up the concussion in the closing of the gate by the wind, or by careless handling.

2. In combination with a cord operated gate, latch 5, keeper 8, and swinging stop 12 of the construction specified, a spring 39 operating to prevent slamming of the gate, as herein described.
