Letters Patent No. 111.903, dated February 21, 1871.

IMPROVEMENT IN SPRING CARRlAGE-CUSHI ONS.

The Schedule referred to in these Letters Patent and making part of the same.

i To all 'lU/tOWL it may concern.- 7

Be itknown that I, THOMAS S. BURNETT, of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Spring Carriage-Cushions; and I do hereby declare that .the following is a full, clear, and exact description thereof, which will enable others to make and use the same, reference being had to the accompanying drawing forming a partof this specification, in which Figure 1 is a front View;

Figure 2 is a cross-section; mm

Figure 3 is a bottom View of the cushion.

Similar letters of reference indicate like parts in the several figures.

In the accompanying drawing 1 A is the seat, and

B is the cushion.

The cushion has a light double frame-work attached to its lower side, and spiral springs are placed between these frames, to give elasticity to the cushlOll.

' The upper frame is shown by O, fig. l, and the lower frame is shown by The front edges of the frames 0 D have a nonelastic bearing on a face piece, E, but are fastened thereto loosely, by screws or other suitable means, in such manner that the rear edge of the upper frame 0 is free to play vertically.

The springs c c are arranged between the upper and lower frames, as shown in figs. 2 and 3, and the tension of the springs is regulated by stops ff of webbing, which are tacked to the rear edges of the frames.

The cushion-straps h h are fastened to thefront edge of the cushion, and do not pass over and across the cushion as usually.

The face piece E has two pins, 0, figs. 2 and 3, which engage with holes in the seat A, to hold the cushion in place, and the cushion is detached from the seat as readily-as the ordinary seat.

The springs c 0 can be. made to rest directly on the seat A, and the lower frame, D, be dispensed with, but I prefer to use. the lower frame, as the cushion is then a separate part from the seat, and can be removed from it at any time, as ordinarily.

By this construction the face piece E makes a firm connection between the frames in a simple and substantial manner, without affecting the elasticity of the cushion at that part where the elasticity is required, and hand-sewing is entirely dispensed with as the covering is of such form that the sewing can be. done entirely with the sewing-machine.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, isp The cushion B, and frame 0 D, the said frame having a stationarybearing at its front edge, on the face piece E, and its rear edge being supported by the spring 0 c, in such manner as to have vertical movement, substantially as and for the purpose specitied.

The above sgecification of my invention signed by me this 6th day of December, 1870.
