SPECIFICATION forming part of Letters Patent No. 620,816, dated March '7, 1899.

Application filed June 4, 1998. Serial No. 682,570. (No model.)

To all whom it may concern.-

Be it known that I, FRANK G. WEsTLANn, a citizen of the United States, residing at Mc- Cook, in the county of Red Willow and State of Nebraska, have invented certain new and useful Improvements in Folding Spring-Seats; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to folding seats, and

is in the nature of an improvement upon a former device of a similar nature, for which Eetters Patent No. 602,788 were granted to me April 19, 1898.

The folding seat contemplated in this invention is designed, like that described in the patent referred to, for use especially in locomotive-cabs and other circumscribed spaces,

wherein a seat is of great convenience to the engineer and it is at the same time necessary that the seat can be folded compactly out of the way when not required.

The present invention relates particularly to the means for holding the seat in position for use and instantly releasing the same when no longer required.

The detailed objects and advantages of the invention will appear in the course of the subjoined description.

The invention consists in certain novel features and details of construction and arrangeinent of parts, as hereinafter fully described, illustrated in thedrawings, and incorporated in the claims.

In the accompanying drawings, Figure l is a perspective view showing the improved seat in its operative position. Fig. 2 is a detail vertical sectional view of the same; and Fig.

3 is a face view of the sliding support with the seat and its brackets omitted, showing the latch-bars.

Similar numerals of reference designate corresponding partsin all the figures of the drawings.

Referring to the drawings, 1 designates a sliding seat-support which is'mounted to slide up and down in a suitable frame comprising upright side bars 2 and cross-bars 3, connect ing the side bars at top and bottom. The said frame is designed to be secured to the wall of the cab, and the support 1 is adapted to slide up and down thereon in order to bring the seat (indicated at 4) to the proper height. The seat is supported upon a pair of brackets or arms 5, provided at their inner ends with pendent lugs or extensions 6 in the shape of elbows. The support 1 is provided at suit able points with projecting ears '7, having openings for the reception of a rod 8, which passes therethrough and also through openings at the elbows of the bars or arms 5, as clearly shown in Figs. 1 and 2. At one side of each ear 7 the sliding support 1 is provided with a slot or aperture 9, of a size sufficient to admit of the rocking of the pendent extension 6 therethrough when the brackets 5 fold downward, as indicated in dotted lines in Fig. 2. In order to lock the seat in position for use, I provide a pair of latch-bars 10 and 11, pivotally connected to the support 1 at the points 12. One of the latch-bars 10 is extended obliquely, as at 13, so as to pass over one of the lugs 7, where it is further extended to form a handle 14. ,The latch-bar 10 is also provided with a slot 15, in which is received a stud 16 at the extremity of the latch-bar 11, said latch-bar being offset, as indicated at 17, so that its inner end may overlap one side of the bar 10, while its outer portion lies in the same plane with the bar 10. Normally the latch-bars 10 and ll'lie across the lower ends of the slots 9, and when the brackets 5are in a horizontal position the latch-bars 10 and 11 interpose themselves between the extensions 6 and the adjacent side of the support 1, as clearly shown in Fig. 2, thus locking the brackets 5 in their horizontal position and holding the seat ready for use. By lifting the handle 14 both latch-bars are moved downward at their free ends, passing out from behind the pendent extensions 6, and thus allowing said extensions to swing through the slots 9, the seat thus dropping to a pendent position alongside of the support 1.

In connection with the seat 4 I employ a back-support 18, mounted on the upper forked end of an arm 19, the lower end of which is bent and extended obliquely and provided with a pintle, which is journaled in a sleeve secured to the adjacent face of the sliding support 1, as described in my former patent above referred to.

It is unnecessary to enter into a description of the back-support 18 and the specific connection between the sliding support 1 and the stationary frame, as said parts are fully described in my prior patent and form 110 part of the present invention, which relates to the particular means for locking the seat in position for use and releasing the same when no longer required.

It will of course be understood that various changes in the form, proportion, and minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In afolding seat, the combination with a vertical support having an aperture, of a seatbracket having a direct pivotal connection therewith, an elbow extension on said bracket adapted normally to work through the aperture in the support, and a latch-bar pivotally mounted on the support, adapted to engage said extension and provided with a lever-arm extending above the plane of the pivoted seatbracket.

2. The combination with a vertical support provided with apertures, of a pair of seatbrackets pivotally connected thereto, extensions or elbows on said brackets, arranged to work through the apertures in the support, latch-bars pivotally mounted on the support and extending across said slots, so as to engage the extensions on the brackets, and means for simultaneously operating said latchbars, sub- Witnesses:
