IMPROVEMENT IN SHIFTING CARRIAGE-RAILS.

Specification forming part of Letters Patent No. 129,140, datedJuly 16, 1872.

Specification describing a new and useful Improved Shifting Carriage-Rail, invented by WILLIAM H. KEENEY, o'f Waupun, county of Fond du Lac and State of Wisconsin.

In the accompanying drawing, Figure l represents a sectional side view of a carriage-seat provided with myimproved shifting-rail. Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

In constructing my improved device I use the ordinary rail D, to which the carriage-top is secured, and to the under side of this rail D, I secure permanently two studs, b, at the rear, and two studs, a, at the front or near the ends. These studs each have their lower ends formed like a tenon to fit into recesses made for them, and each has a recess or notch formed in one edge of this tenen part, as shown clearly in Fig. 1the rear ones b having the notch formed in their rear edges, while their front ones a have the notch formed in their front edges or sides. I then attach a hand-rail, B, to front end of the raised ends or side pieces of the seat A, as shown in Figs. 1 and 2, and through each of these make a vertical hole for the front hooks a to fit into, these hooks be ing of sufficient len gth to protrude through the rail B and bring the notch entirely belowl the rail, as represented in Fig. l. On the under side of these hand-rails B I pivot a lever, E, in such a position that their rear ends will lit in the notch on the front side of the hooks or lugs a., thus locking them fast, as shown in Fig. 1, the lever E turning laterally on the pivot G. At the back of the seat I extend up two metal straps, C, which are bent bach at their upper ends so as to protrude over the top of the back of the seat A, as shown in Fig. l. In this bent portion of these straps G I form a vertical slot, F, which runs out at the front side, but is not cut through at the rear, thus leaving at the rear side a solid portion of the proper thickness to fill the notch in the rear side of the studs b.

With the parts thus constructed the operation is as follows: The top is set upon the seat, with the hook portion of the lugs b resting in the slots F, when the top is shoved back as far as it will go, thereby causing the hooks on the studs b to engage with the rea-r portion of the straps C, when the front studs@ are dropped into the holes in the front or hand rails B, and

the levers E are swung so as to lock into the notches on the front of said studs a, thereby securing the cover firmly in place, as represented in Fig. l. To remove the top the levers E are disengaged, the studs a lifted out of their seats, and the cover drawn slightly forward to disengage the rear hooks, when the top is lifted off.

The device is exceedingly simple and efficient, and can be used without springing the rail D to bring the studs into place, and without turning the top over, asin many others.

Having thus described my invention, what I claim is- The perforated hand-rails B, having the levers E pivoted to their under side, with the slotted straps G, and the rail D, provided with the studs a and b, having notches formed in their opposite faces, and all arranged to operate as and for the purpose herein set forth.
