SPECIFICATION forming part of Letters Patent No. 423,681, dated March 18, 1890.

Application filed August 2, 1889. Serial No. 319,552. (No model.)

To all whom it may concern:

Be it known that I, DAVID W. GLIDDEN, of Montrose, in the county of Susquehanna and State of Pennsylvania, have invented a new and Improved Wagon Seat Look, of which the following is a full, clear, and exact description.

- This invention relates to wagon-seat locks, the object of the invention being to provide a lock which shall be simple, cheap, and durable, and at the same time easily manipulated, and one wherein the parts shall be .so arranged that the seat may be readily moved from place to. place upon the seat-rail.

To the ends named the invention consists of certain constructions, arrangements, and combinationsof elements, to be hereinafter fully described, and specifically pointed out in the claims. 1 v

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

Figure 1 is a side view of a portion of a seat riser or standard and a portion of the seat=rail, representing the same as it appears when provided with my improved lock. Fig. 2 is acentral sectional view on line as a; of Fig. 1. Fig. 3 is a perspective view of the bed-plate, and Fig. 4 is a perspective view of the lock proper.

In the drawings, 10 represents a bed-plate that is arranged for connection, by means of screws 11, with a wagon-seat riser 'or standard 12. This bed-plate 10 is formed with an outwardly-extending boss 13, which said boss passes through a longitudinal slot a, that is formed in a slide 14.

To the lower end of the slide 14 there is hinged a catch 15, having a groove or recess 1), which is entered by the lower end of the bed-plate when the parts are adjusted as represented in Figs. 1 and2. In order that the slide 14 may beproperly guided and held from binding upon the lug or projection 13,1 form said slide with a second slot 0, through which there is passed a stud or screw 17, said stud being made integral with the bed-plate or' passing through the said bed-plate to engage the body of the seat-riser. The projection 13 is provided with or formed to receive a stud 18, which passes through an eccentric locking device 19, having a weighted handle 20, the eccentric face at of this locking device bearing against a lug or projection 21, which ex-,

tends outward from-the face of the slide 14,

the arrangement being such that when the locking device is turned to the position in which it is shown in Fig. 2 the hinged catch 15 will be drawn upward to the position in which it is shown in .the drawings, all accidental displacement of the parts being pre vented, owing to the fact that gravity will act to hold the locking device in the position in.

which it is shown in Figs. 1 and 2.

In applying the lock-above described the bed-plate is secured to the seat-riser in a position such that it will bear closely under'the seat-rail 30 when the locking device is moved to the position shown in Figs. 1 and 2, the lower portion of the bed-plate at this time bearing against the face of theseat-rail and ,taking up all lateral strain which might oth- .up, which will carry the slide 14 downward and permit of the throwing of the catch 15,

as indicated by the 'arrow shown in connection therewith in Fig. 2. Then if the handle be released the slide will be thrown upward and the catch will be prevented from returning to its normal position beneath the seatrail, so that the seat may be readily raised from said rail.

Having thus described my invention, I claim as new and desire to secure by Letters Patent g 1. In a seat-lock, the combination, with a ,bedplate arranged for engagement with the seat-riser and to extend below the seat-rail, of a slide held to the base-plate, a hinged catch carried by the slide, and a gravity looking device, substantially as described.

2. In a seatlock, the combination, with the bed-plate arranged for connection with the seat-riser and to extend below the seat-rail, said plate being formed With a projection 13, of a slide slotted to receive said projection, a catch-hinged to the slide and provided with a 5 recess 1), and a gravity locking device, substantially as described.

3. In a seat-lock, the combination, With a bed-plate 10, formed with a projection 13, of a slide formed with slots a and b, the proj ee- 10 tion 13 passing through the slot a, a stud or v screw which engages the bed-plate and passes through the side slot 0, a gravity locking de- Vice pivotally connected to a stud carried by the projection 13, and a catch hinged to the slide and formed with a recess 17, adapted to be entered by the lower end of the bed-plate, substantially as described.
