SEAT-LOCK FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 308,104., dated November 18, 1884.

Application filed August 6, 1884. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW ESAIAS STEEL, a citizen of the United States, residing at Lake City, in the county of Wabasha and State of Minnesota, have invented a new and useful.

Improvement in Seat-Locks for Carriages and W'agons, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to a carriage and wagon seat lock; and it has for its object to provide a device of this character which shall be cheap and simple in its construction and effective in its operation.

The invention consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claim.

In the drawings, Figure 1 is a perspective view showing my improved lock applied to a portion of the top rail of a carriage and a portion of the seat. Fig. 2 isa top view showing the peculiar form of slot or opening for the reception of the locking bar or key. Fig. 3 is a detail view of the locking bar or key, and Fig. 4 is a vertical cross-section.

In the accompanying drawings, in which like letters of reference indicate corresponding parts in all the figures, Arepresents a portion of the top rail of a carriage or wagon, and B a portion of the seat.

Upon the side of the top rail, A, is secured a metal plate, 0, which is formed about midway its length with an enlarged portion, E, which has a vertical passage or opening, a, which is irregular in form, being larger at 1) than at its other end, 0. The plate 0 is cast and the enlarged portion E formed therewith. The irregular opening or passage in said enlarged portion is then bored or drilled.

Upon the inner side of the seat portion B is provided an inverted-T-shaped metal plate, F, which is formed with an enlarged portion,

G, which is similar to the enlarged portion E of the plate 0.

It will be seen that by constructing the plate F of a T shape the shank of the plate serves to brace the seat portion and prevent it from splitting.

G represents the locking bar or key, which consists of the body portion 6, having an outwardly-extending nib or lug at its lower end, which nib or lug fits in the small end of the vertical opening or passage. The upper end of the said shank is formed with an outward- 5 ly-extending handle, H, which, as shown, is curved, so that when the locking bar or key is turned down, as shown in Fig. 1, to lock the parts, it may be readily raised, where, if it were perfectly straight, it would lie flat upon the wagon-seat, and make it almost impossible to raise said handle by hand.

The operation isas follows: The seat is adjusted upon the top rail of the carriage or wagon so that the openings or passages of the enlargements formed upon the plates 0 and F will register. The locking bar or key is then inserted so that the nib or lug will fit the small end of said opening. The locking bar or key is then pushed downwardly until its lug has passed entirely through the openings of said enlargements. The key is then turned down to the position shown in Fig. 1, and as the enlargement is thicker at the point occulpied by the lug when turned down than atthe opposite side,'it will be seen that it requires some little force to lock the parts but when locked they will be securely held in that position, and there will be no liability of their becoming detached.

It will be seen that in securing the seat as described two sets of plates and two locking bars or keys will be employed. It will also be seen that the plates and keys will be cast rights and lefts. By this arrangement the po- 8 5 sitions of the handles of the keys when locked will be the same, thus placing them within easy access, and allowing them to be readily unlocked when so desired.

The lock above described is simple in its construction, may be manufactured and supplied at a slight cost, and is strong and durable.

In order to point out more clearly the advantages and scope of my invention, I would have it understood that I do not seek to claim anything shown in the patent of William A. Lamb, dated July 7 1874, No. 152,849; but,

Having fully described my invention, what I sisting of body portion a, having nib or lug, I claim as new, and desire to secure by Letters as shown, and a handle, H, as described. Patent, is I In testimony that I claim the foregoing as The combination, with the top rail, A, havmy own I have hereto affixed my signature in 5 ing a plate, 0, provided with an enlarged porpresence of two witnesses.
