structural details, will definitely appear from the detailed description appearing hereinafter.

The invention consists in certain novel features in construction and in combinations and arrangements as more fully and particularly set forth and specified here inafter.

Referring to the accompanying draw- 1ngs:

Figure 1, is a vertical section through a spring seat to which my invention is applied.

Fig. 2, is a detail perspective view.

Fig. 3, is a detail perspective view of a modified construction.

In the spring seats of the general type disclosed in the accompanying drawings, a suitable covering of fac ng nniterial or upholstery is provided which extends over the top and sides of the spring construction and is customarily fastened to the lower frame thereof in any of a number of ways. This fastening is accomplished by providing frames of wood, or the like material. and nailing or tacking the ends of the seat covering thereto, or, where metal frames are used by various complicated and other expensive arrangements and constructions which often require the use of machinery or special tools in fastening the covering thereto and which in a number of instance necessitate sewing or providing the ends of the covering with binding or einforcing members. A prevailing arrangement. in the art, where metal frames and cover fastening means are used, is the provision of various forms and constructions of teeth, prongs, and the like, which are forced, through the covering material and bent over thereon or clenched. methods and constructions for accomplishing' the fastening of upholstery or seat covering material to the spring construction of spring seats, or other seat constructions, are more or less complicated and expensive and necessitate a number of operations to form the completed fastening. The invention embodied in my present application,

by the arrangement and construction de-' All of these covering material to cring material therein and thereto.

the spring construction of spring seats. This binding or locking means consists of a member which is formed to receive the The upholstery or seat covering is securely locked in and to this receiving member which is rigidly fastened to a frame of the spring construction, and in this manner, the upholstery or seat covering material is tightly maintained upon and in proper relation with respect to the spring seat construction, without the use of tacks, prongs, teeth, or the like, or the complicated or expensive arrangements and constructions heretofore used for this purpose.

Referring to the particular example illustrated by the accompanying drawings, I show a spring construction consisting of the frames 1 and 2, and a series of sprial springs 3 within the frames and fastened thereto. The springs 3 may be fastened together and braced in any of a number of well known ways and those springs adjacent the frames 1 and 2 are fastened thereto by metal clips, or the like, such as 4:. Upholstery or seat covering material 5 is placed across and completely covers the top of the spring construction and depends down and covers the sides of the construction and extends a distance past the lower edges thereof. The upholstery 5 thus completely covers the top and sides of the spring construction.

.The above description, of the specific example illustrated, is typical of the general type of spring seat construction, in which a series of spiral springs are mounted in and fixed with respect to metal or the like, frames at the opposite ends of the springs, and upholstery or covering material is placed upon one of the frames covering the space across said frame, depending across all of the sides, and fastened to the opposite or bottom frame.

Various devices and arrangements have been used to fasten the depending upholstery or covering to the lower frame, and my invention is directed particularly to such a device,although of course, it is not limited to use upon the specific arrangement of spring construction disclosed but is applicable to a variety of such constructions.

The device of my invention comprises two members, the upholstery or covering material receiving member A and the bind ing or locking member B which is applied to the member A and binds or locks the upholstery or covering material thereto and there in. The member A, in the particular example illustrated, is in the form of a channel the means which fasten the channel strip A to the frame of the spring construction by being bent tightly therearound, as clearly shown in the accompanying drawings.

The binding or locking member B is formed of a strip orribbon of sheet material in thickness less than the internal width of the space or channel in the member A and approximately equal in width to the depth of the said space or channel. This locking member 13 is adapted to be forced into the channel strip for the purposes and in the manner appearing hereinafter.

A spring seat being provided with the binding or locking member A in theform of a channel or U shaped member, fastened thereto by means of the tongues or clips 10 as explained, the operation and method by which the upholstery or seat covering mate rial is bound or locked therein and thereto and is maintained in position upon the spring seat, is as follows:

The depending ends or edges of the upholstery or covering material 5 are cut off so that they extend or depend a distance be yond the lower or outermost edge of the channel strip A. approximately a distance equal to the depth of the channel or space in the strip. However, as shown in the drawings, the depending ends of the material 5 may be of such length to permit curling over and depending a distance downwardly in the top of the strip A. The upholstery or covering material is then stretched tightly on and over the spring construction and its free or depending ends forced or thrust into the channel or space in the channel strip A, formed between the sides 6 and 7, thereof. As soon as the endsof the material are in this position the binding or looking member B formed of the strip or ribbon of sheet material having been bent into theshape or outline of the channel in the member A, is forced into this channel 9 parallel to the ends of the material 5 therein and between these ends and the inner wall 6 of the channel strip. As pointed out the sides 6 and 7 of the channel strip are resilient and as the thickness of the material and the binding or locking strip B together are greater than the width of the channel 9, the sides 6 and 7 will be forced outwardly but will tend-to return to their normal positions, thus exerting a pressure against the material and the strip therebetween and securely locking them therein, and where the end of the material is curled over in the top of the channel strip the member B will bear thereagainst and securely hold the ends of the material 5 therein. This locking efiect is aided further and increased by the fact that the material 5 is compressed, to a certain extent, by the action above pointed out and also exerts pressure against the members between which it lies. In this manner the upholstery or covering material 5 is firmly and securely maintained in position upon the spring seat.

In Fig. 3, I have shown a modified construction of my invention in which the receiving member or channel strip A is formed with an interior longitudinal groove 11 in the side 7. In this arrangement the locking strip takes the form of a wire or rod as B which is adapted to be forced into the channel 9 between the sides 6 and 7 of the member A and to seat in the longitudinal groove 11. The ends of the covering material 5 are inserted in the channel strip A and the wire or rod locking member B is forced into the channel strip A, between the covering material 5 and the inner side 6 of the member A, until it seats in the groove 11. As the material 5 is between member B and groove 11, it is forced into the groove by the wire or rod B and is locked or bound in and to the receiving strip A. The spring or resiliency in the sides 6 and 7 maintains the wire or rod B in the groove 11, thus securely locking the ends of the covering material in the channel strip.

The binding or locking strips 13 or B may be readily removed from the channel strip A to release the seat covering material ends therefrom. That is, my invention provides an arrangement whereby the upholstery or seat covering material may be fastened to a spring seat construction in such a manner that it may be easily removed therefrom, and without in any manner mutilating or defacing the material.

A spring seat provided with the upholstery binding or locking means of my invention presents a finished, neat appearance, as the lower edges of the seat are covered by the material turned over the lower edge of the outer side 7 of the channel strip A, thus forming a smooth rounded edge at the bottom of the seat, as shown in the drawings.

My invention may take other forms and constructions than the specific channel strip and locking member of the drawings and other arrangements can be provided for fastening the receiving member A to the lower frame of the spring construction without departing from the spirit and scope of the invention. I also do not wish to limit my self to the particular location of the receiving member A upon the spring seat as it is obvious that the same results and advantages would be secured at other points on a spring seat. My invention resides in the use of two members, one adapted to receive the material and the other lock the same therein and thereto, the receiving member formed with means whereby it can be securely and rigidly fastened to a spring seat, and the above results obtained without the use of the complicated and expensive arrangements and constructions of the art.
