ATTORNEY Patented May 13, 1930 UNITED STATES PATENT OFFICE WALTER F. HEROL D, OF "UPPER MONTCLAIR, NEW JERSEY, ASSIGNOR TO THE BASSICK COMPANY, OF B RIDGEPORT, CONNECTICUT, A CORPORATION OF CONNECTICUT FURNITURE SLIDE OR SHOE Application filed January 25, 1928. Seria1 N o. 249,411.

The present invention relates to an improved furniture slide or shoe, and has for an object to provide, a device of this character which may be readily attached to a furniture leg by being driven into the same, and further to provide a slide adapted to have a tilting action with respect to the leg, so that the latter may be tilted while the slide maintains a firm flat engaging andsupporting relation with the -floor, without tearing .out of the wood, as would be the case with a non-tilting slide, this being particularly so with the nonmetallic, more or less fragile material employed in slides to a great extent at present. A further object is to provide a tilting slide which may be attached without the necessity of boring the furniture leg, and having a nontilting attaching means which may be direct- 1y hammered into the furniture leg without hammering upon the tilting slide portion. A still further object is to provide a device in which the attaching element driven into the leg will have a complete circle of metal embedded in the wood, and acting as a dowel to take side strains, so that the attaching teeth driven into the wood are relieved of such strains.

With the above and other objects in view embodiments of the invention are shown in the accompanying drawings and these embodiments will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

In the drawings Fig. 1 is a side elevation of a furniture slide or shoe, according to the present embodiment of the invention;

Fig. 2 is a plan view thereof;

' Fig. 3 is a vertical sectional view;

Fig. 4 is a vertical sectional view showing the same attached to the furniture leg;

Fig. 5 is a similar view showing the tilting positions;

Fig. 6 is a vertical sectional View of a modified form of the invention.

Similar reference characters indicate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, and more particularly to Figs. 1 to 4 thereof, the furniture slide or shoe, according to the embodiment shown therein, comprises a base 10, preferably solid and formed of bakelite or other suitable material, having a flat floor-engaging bottom surface 11, and an upper surface in the shape of a spherical dome 12, annularly shouldered at 13. A central opening 14 ex- .tends Vertically through the base, being restricted at its upper end to provide an annular shoulder 15 having a spherical curvature. The dome 12 is of asuitable radius to provide a curved seat for the furniture and toprovide ample material to resist crushing stresses between the upper surface and the wall of the opening 14. V

The attaching member employed is in the form of a cup comprising a concavo-convex base 16and an annular upturned wall 17 having a series of driving teeth 18, the bases of which are in upwardly spaced relation to the base 16, so that a complete continuous circle of metal is provided between the teeth and said base. The teeth are of a type adapted to be readily driven into wood by hammer blows and to form an interlocking connection with the wood fibres against ready removal, the forward edges being inclined rearwardly from the point, as at 19, and notched at the base, as at 20, the notched base of each tooth being connected to the relatively long inclined rearward edge of the preceding tooth..

Obviously other types of teeth may be employed. A shouldered pin 21 is secured in a central aperture of the cup member by heading the same over upon the upper or convex surface, as at 22, the shoulder of the pin engaging beneath a concavo-convex metal washer 23, centrally apertured at 24, and of a diameter less than the base of the dome 12, and interposed betweenthe dome 12 and the cup member. The pin is loosely engaged for tilting movement in the upper restricted end of the opening 14 of the base, being provided at its lower end with an enlarged rounded head 25 which engages the shoulder 15 of said opening 14 to thereby retain the parts in connected relation. The diameter of the pin 21 is such, with relation to the aperture 24 of the washer 28, as to permit insertion of the pin and relative turning movement about the vertical axis of the pin, while the diameter of the restricted end of the opening 14: is greater than that of the pin, and the enlarged portion greater than that of the headed end 25, so that, in combination with the smaller diameter of the washer 28 with relation to the base of the dome 12, a relative limited tilting movement is permitted, as between the base 10 and the cap member. This is clearly indicated in Fig. 5.

The device is adapted to be driven into the furniture leg by hammer blows applied directly upon the rigid center pin of the cap member, and without engaging the tilting base. For this purpose a driving pin 26 is supplied with each set of slides and is adapted to be inserted in the opening 14 into direct engagementwith the headed end of the pin 21, the teeth of the cap member being driven into the wood by hammering upon said pin 26. The teeth form an annular channel in the wood into which the continuous circle of metal between the teeth and the base enters, the fibres of the wood entering the notched formations of the teeth to form an interlocking connection, as clearly indicated in Fig. 4. The continuous circle of metal, it will be observed constitutes a dowel substantially embedded in the wood which takes side strains, the teeth being relieved of such strains, so that there is no tendency for the same to bend or loosen, his being particularly effective under the uneven stresses set up in the tilted relation of the base.

In Fig. 5 I have illustrated a slight modification in which the washer 23 is omitted, the concave under surface of the cup member being engaged directly with the domed surface of the base. In this form I have also shown a centering spike 27 formed upon the upper end of the pin 21.

I have illustrated and described a preferred and satisfactory embodiment of the invention, but it will be obvious that changes may be made therein, within the spirit and scope thereof, as defined in the appended claims.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. A furniture support comprising a base having a floor engaging bottom surface, and having an opening extending therethrough from top to bottom, the top surface of said base being shaped to provide a curved seat, furniture engaging attaching means disposed at the upper side of said base and adapted to be driven into the furniture and movably supported with relation to said curved seat, said attaching means including a headed pin engaged within said opening with its head entirely within said opening, said opening being restricted above said head to retain the base with respect to said attaching means.

2. A furniture support comprising a base having a floor engaging bottom surface, and

at the upper side of said base adapted to be driven into the furniture and having a curved seat movably supported with relation to said curved seat of the base, said attaching means adapted to be driven by blows directly applied thereto through said opening of the base.

8. A furniture support comprising a base having a floor engaging bottom surface, and having an opening extending therethrough from top to bottom, the top surface of said base being shaped to provide a curved seat, furniture engaging attaching means disposed at the upper side of the said base and having a curved seat movably supported with relation to said curved seat of the base, and a concave-convex washer interposed between said curved seats, said attaching means adapted to be driven by blows directly applied thereto through said opening of the base.

4;. A furniture support comprising a base having a floor engaging bottom surface, and having an opening extending therethrough from top to bottom, the top surface of said base being shaped to provide a curved seat, furniture engaging attaching means disposed at the upper side of said base adapted to be driven into the furniture and having a curved seat movably supported with relation to said seat of the base, a headed pin connected to said attaching means engaged within said opening with its head entirely within said opening, said opening being restricted above said head to retain the base with respect to said attaching means.

5. A furniture support comprising a floor engaging base, furniture engaging attaching means secured to said base to permit relative tiltingmovementbetween them, and including a base portion, a continuous upstanding rim portion, and a series of teeth extending upardly from said rim portion, said teeth and said rim portion adapted to be driven into the furniture, and said rim portion adapted to resist side strains and absorb side strains with respect to said teeth.

6. A furniture support comprising an unyielding floor engaging base, attaching means adapted to be driven into a solid furniture leg, and means permanently connecting said base to said attaching means and permitting relative tilting engagement between them, said attaching means including an unyielding driving portion adapted to receive driving blows directly applied thereto independently of said permanently connected base.

7. A furniture support comprising a base having a floor engaging bottom surface and having an opening extending upwardly therethrough from said bottom surface, attaching means adapted to be driven into a solidfurn-iture leg, and means permanently connecting said base to said attaching means and permitting relative tilting movement between them, said attaching means including an unyielding driving portion exposed through said opening of the base and adapted to receive driving blows directly applied thereto independently of said permanently connected base.
