ROCKING-CHAIR CLAMP.

Specification of Letters Patent.

Patented June 5, 1917.

Application filed August 9, 1915. Serial No. 44,430.

Y '0 all whom it may concern:

Be it known that I, SILAs D. BELL, a citizen of the United States, residing at Childress, in the county of Childress and State of Texas, have invented certain new and use ful Improvements in Rocking-Chair Clamps, of which the following is a specification.

My invention has relation to an attachment for converting ordinary chairs into rocking chairs and in such connection it relates more particularlyto the arrangement and construction of such a device.

The principal objects of my invention are first to provide a means whereby an ordinary chair may be converted into a rocking chair without destroying the identity of the chair as a chair and without boring the rockers and without trimming down and gluing the legs of the chair to fit said legs and fasten the same to the rockers, and second to provide a clamp of simple and inexpensive construction adapted to secure aleg of a chair firmly and detachably to a rocker.

In carrying out my invention there is provided a clamp consisting of two pieces of metal, preferably sheet steel relatively resilient, each piece being curved or are shaped in side elevation and having an upper end rounded to partly inclose the chair leg and a lower end rounded and inwardly bent to firmly engage the side of a rocker, said pieces being adjustably secured to position by a bolt and nut, the bolt traverslng a series of openings arranged in the pieces intermediate of their ends.

The nature and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which,

Figure 1, is a perspective view of a rock ing chair embodying the main features of a my invention.

Fig. 2, is a side elevational view enlarged of one leg, a rocker and the clamp for uniting the leg to said rocker.

Fig. 3, is a top or plan view of Fig. 2, and

Fig. 4, is a vertical sectional view taken on the line a, 0:, of Fig. 2.

Referring to the drawings, 1 represents a chair of ordinary construction and-2 its legs, and 3, 3 the rockers for converting chair 1 into a rocking chair. The legs 2 of chair 1 may be cut or planed at their basesor lower ends so as to fit the upper curved surface of the rockers 3. The clamp for securing a leg 2 to a rocker 8 consists of two similar but oppositely formed pieces 4 of metal, preferably sheet steel or similar resilient or spring metal. Each piece has a forward end 5 rounded or curved to fit snugly upon the exterior rounded surface of a leg 2. If said leg 2 should be square or rectangular it is obvious that the end 5 will be shaped correspondingly to fit snugly the angular surface of such a leg. The body of the piece or plate 4 is curved downwardly and terminates in a lower gripping end 6 which is formed by bending the plate first outwardly, then downwardly and then inwardly as clearly shown in Fig. 4. The body of plate 4 is provided with a series of perforations 7 intercommunicating by narrow slots 8 of a width preferably to permit the bolt 9 slicing from one perforation to the next when the nut 10 of the bolt 9 is unloosened. The bolt 9 traverses both pieces 4 with the head 11 of the bolt on the out side of one piece 4 and the nut 10 on the outside of the other piece 4.

In assembling the parts together, the plates 4 are held loosely together by the bolt 9 and nut 10, the forward ends are brought to encircle the lower end of a leg 2 and the gripping ends are slipped over the sides of a rocker 3. When now the nut 10 is advanced on the bolt the plates 4 are brought together to firmly grip the leg and rocker and to securely clamp the rocker to the leg.

When the rockers are not to be used, it is an easy matter to remove clamps and rockers from the chair legs. In case of repairs a clamp may be used to secure a leg, which has been broken, to the rocker.

Having thus described the nature and objects of my invention what I claim as new and desire to secure by Letters Patent, is,-

The combination with a chair leg and a rocker, of a clamp comprising two curved resilient metal plates, each provided with a forward end to partly inclose the leg and a lower gripping end to engage the side of a rocker, a series of perforations traversing the body of each plate, a bolttraversing registering perforations of the plates, and a nut In testimony whereof I have signed my name to this specification.

SILAS D. BELL.
