UNITED STATES PATENT OFFICE.

GEORGE F. GODLEY, OF PHILADELPHIA, PENNSYLVANIA. v

CAR-SPRING SEAT.

SPECIFICATION forming part of Letters Patent No. 499,338, dated June 13,1893.

Application filed March 29, 1893. Serial No. 468,114. (No model.)

To all whom it mwy concern.-

Be it known that I, GEORGE F. GODLEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Oar-Spring Seats, of which the following is a specification.

My invention relates to improvements in car spring cases and consists of certain specific features fully set forth in the following specification and accompanying drawings forming part thereof. My invention relates to that class of car spring cases where double plates are used and between which plates are placed the usual compression springs common in cases of this class.

The object of my invention is to cheapen the cost of manufacturing car spring cases and at the same time have a strong and durable spring seat and one of extreme simplicity in its construction.

Similar figures are used in the different views to represent like parts.

Figure 1 is a plan of the top plate of my car spring case; Fig. 2 a section on line as w of Fig. 1, and Fig. 3 is a perspective view of the bolting mechanism for holding the plates together.

This specific construction forms an important feature of my mechanism and in combination with the round shaped depressions for retaining the spiral springs in their proper places, the cost of manufacturing is reduced and the practical efficiency augmented.

10, 10, 10, 10, &c., are a series of round shaped depressions in the metallic plates. They are not only round circumferentially but also in cross section. The function of the said depressions is to retain the spiral springs in their proper place, serving the purpose of a retaining guide for the said springs to the aforementioned end. In practice these depressions are stamped or pressedin the sheet metal, suitable dies being provided therefor. The rigidity of the plate is thereby greatly increased and the maximum of strength obtained at a minimum of cost.

In Fig. 1 is shown in plan and in Fig. 2 in section a series of depressions 4, 4 and these depressions are in effect and in fact lugs on the plates 1, 1 and serve as auxiliary guides for the aforementioned spiral springs. They could however be entirely dispensed with if desired.

12 is a depressed recess in the upper plate 1 and made to accommodate the nut 2 of the bolt or link rod 5. This depression 5 is likewise stamped or pressed in the upper plate. The lower plate 1 is also made from sheet metal and in addition to the round shaped depressions 10, 10, 10, 10, stamped or pressed therein I cut from the metal plate the link 7 and bend it up at a' right angle to the body of the plate 1, after first, however, punching from the metal composing the said link the eye 7 as shown in Fig. 3. This leaves the link 7 an integral part of the bottom plate 1 and, as is apparent the cost of manufacturing the same is thereby reduced to the least degree. Fig. 3 shows clearly the manner in which this link is engaged by the rod or bolt 5. This rod 5 consists of a single piece of metal either round or flat bent or made to engage in the eye 7 and after being placed in the aforementioned eye in the manner shown in Fig. 3 the body 5 of the bolt is put through the hole in the top plate 1 and the nut 2 applied. The bent end 6 of the rod 5 will have free vertical play in the eye '7 and will therefore accommodate itself to the requirements of the compression and extension of the springs when in use. This construction allows of the connecting bolt 5 between the top and bottom plates to have vertical play at both ends and yet be secure, which is a decided advantage.

I do not limit myself to the mere specific details of link construction as numerous modifications of construction could he made without departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A car spring case consisting of a top and bottom plate, a link formed from and inte- 5 with book 6 or equivalent, as and for the IQ gral with said bottom plate and a belt or rod purpose specified.
