GATE.

SPECIFICATION forming part of Letters Patent No. 386,230, dated July 17I 1888.

Application filed January 2S, lSSB. Serial No. 262,234. (No model.)

.To @ZZ whom it may concern:

Be itk nown that I, MARTIN LUTHER BAKER, of Tilton Junction, in the county of Muscatine and State of Iowa, have invented a new and Improved Gate, of which the following is a full, clear, and exact description.

My invention has for its object to provide a simple, inexpensive, and substantial farmgate, which may bc opened and closed quickly and easily by a person ou a vehicle or on horseback, by simply pulling cords at the roadside. The gate is automatically held or latehcd as it closes to prevent opening of it by stock, and will not be obstructed by ordinary storms.

The invention consists iu certain novel features ofconstruction and combinations ofparts of the gate, all as hereinafter described and claimed.

)teferenee is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis aside elevation of the gate, shown open in full lines and closed in dotted lines. Fig. 2 is a plan View ofthe gate in closed position. Fig. 3 is an end view with the gate proper in vertical section on the line as x in Fig. l; and Fig. 4 is an enlarged detail plan view at the main gatepost, which is shown in horizontal section.

The main post A and one side post, B, of the gate are set at opposite sides of a road, C, which the gate proper, D, is intended to close or open, and the other shorter post, E, is set at the other side ofthe main post as a support to the gate and to stop it when open. The main post A consists of two uprights, a a,which are preferably framed into a sill-timber, a, which rests on a foundation, to which it is held by pins or stakes a2, and the tops of the uprights a a are connected and at the same time stayed apart by a head-piece, a3, said uprights a c being separated sufficiently to allow the gate D to run between them in a manner presently explained. The post B is preferably framed into a sill, b, which rests on a foundation, and is held thereto by pins or stakes b', while the other side post, E, is simply set or driven into the earth, as it partially supports the gate D only when the latter is open. Plates or cheek-pieces b2 b2, fixed to the post B, prevent lateral play of the outer end of the gate when it is closed.

The body of the gate D may have any ordinary or approved construction. It is shown made with wooden uprights d d d?, and longitudinal rails and diagonally-ranging braces, with wire or metal stringers between the rails. The outer end upright, d, ofthe gate D is shorter than its otherend upright, d', and these parts d d carry at their upper ends rollersfg, respectively, which travel upon metal tracks or rails F G.

The track F is fixed at one end to the post E, and at its other end is passed between the uprights a a of the post A, land is then bent around atf and is fixed to one of these uprights. Nearits bent end f the track F is depressed atfi, and ata point,f3, about midway between the gate-posts A E, the track is highest, whence the track inclines gradually to its depression f'l and the post E. The track G is fixed at one end to the post B and extends across the road C and between the uprights c c of the post A, and is tiXed at its other end at g to a bar, I, which is fastened to the post A and ranges lengthwise of the roadway C for some distance for attachment of the gate-operating cords, as presently explained.` The track G is provided with a depression, g2, next the post B, and is highest ata point, g3, about midway between the posts A B.

The bar I is preferably stayed to the post A by braces it', and at opposite ends carries pulleys or sheaves j 7c, through or over which are passed the cords J K, respectively, which are passed between pairs of guidepulleys L M, gjournaled in strap-bearingslm, fixed to the uprights a a of the gate-post A. The inner ends of both the cords J K are attached to a stirrup or bail, N, which is pivotally connected to the upper central portion of the gate D. The pairs of pulleys L M guide the cords J K, respectively, as the gate opens and closes.

The operation of the gate is very simple and effective, and is as follows: We willsuppose the gate 1s closed across the road C, as shown in Fig. 2 of the drawings and in dotted lilies in Fig. l, and that a person, either on a loaded vehicle or on horseback,approaches the gate in the directionof the arrow. W'hcn he reaches the pendent cord J, he will pull it sharply, and

IOO

ing let go in time the gate will open the resty ofthe way of ils own accord as the rollers run down the farthest downwardly-inclined parts of the tracks and until the gate-upright d stops against the post E, both the cords J K then paying out beneath the outer rollers, L M. After the load or horse has passed the gateway, the person will pull on the cord K,whch will close the gate again to the post B, and as the gate fully closes the rollersfg will lodge in the depressions]cz g of the tracks F G, and thereby prevent opening of the gate by stock rubbing against it, these rollers and trackde pressions thus serving as a latch to the gate. A short sharp pull on the cords J K is all that is necessary to effect an easy and complete opening and closing of the gate, which otherwise operates automatically, allowing the gate to be opened and closed without requiring a person'to leave a vehicle or disniount from a horse. The track G is high enough to allow full loads of hay to pass under it.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the posts A B E, of the tracks F G, secured to the posts A E and A B and provided with depressions f2 g2, respectively, and the gate D, provided with rollers 011 the upper ends of its end uprights, substantially as described.

2. The combination of the posts A B E, the post E being of less height than the posts A B, double-inclined track F, secured to the posts A E and provided with the depression f, the double-inclined track G, secured to the posts A B and provided with the depression g2, the gate D, having its end uprights of unequal height and provided with the rollersf g on the said uprights, the bar I, secured to the post A, the guide-pulleysj 7c L M, and the cords or ropes J K, attached to the gate and passing over the said pulleys, substantially as herein shown and described.

3. The combination, with the posts A B E, the post E being of less height than the posts A B, and the bar I, secured to post A, of the double-inclined track F, provided with the depression]2 and having its ends secured to the posts A E, the double-inclined track G, provided with the depression g`z and having its ends secured to the post B and to the bar I, the gate D, having its end posts, d d', of un- .eqnal length and provided with the rollersf g, the guide-pulleys] kin the ends of the bar the pulleys L M in bearings on the post A. and the ropes J K, connected to the center of the gate and passing around the said pulleys, substantially as herein shown and described.

MARTIN LUTHER BAKER.
