DEVICE FOR FASTENING FURNITURE-TRllVlNllNGS.

.SPECIFICATION forming part of Letters Patent No. 745,404, dated December 1, 1903.

liipplicatinn filed August 8, 1903.

To all whom it may concern:

Be it known that I, DANIEL W. TOWER, a citizen of the United States, residing at Grand Rapids, in thek county of Kent and State of IlIichigan,-hare invented a new and useful Device for Fastening Furniture-Trimmings, of which the following is a specification.

This invention relates to certain improve ments in devices for securing handles, pulls,

io knobs,and similartrimmin'gs tofurniture and the like, and has for its principal object to provide a securing device that will securely held a knob or other trimming-in place, vpreventing turning or loosening of the knob or l5 pull under all conditions of use.

A further object of the invention is to provide a securing device that will in part embed itself in the wood and prevent turning of the secnring-screw,and,further,to apply thesame zo construction to a knob or handle, so that neither the knob nor the screw can be turned and the knob held permanently in place.

A still further object of the invention is to provide a knob-securing device of simple and z5 economic construction in which the securing member proper may be formed of steel, iron, or other cheap metal and concealed by an ornamental hood or washer of ornamental character.

Vith these and other objects in view the invention consists in the novel construction and arrangement of parts hereinafter described,illustrated in the accompanying drawings, and particularly pointed out in the ap- 55 pended claims, it being understood-that various changes in the form, proportions, size,

and minor details of the structure may be made Without departing from .the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a sectional elevation of a drawer-knob or the like provided with a fastening means in accordance with the invention. Fig. 2 is a detail perspective View of the knob. Fig. 3 is a similar view of the knob-locking washer and the ornamental washer that conceals it.

Fig. 4l is a similar view of the headed portion of the screw andthe screw-locking washer.

5o Fig. 5 is a sectional viewillustrating the application of theinvention to an ordinary form of drawer-pull. Figs. 6 and 7 are views of Serial No. 168,8().3- (No model.) l

slightlymodified constructions of washer. Figs. 8 and 9 are similar views of slight modiiications of the screw-heads.

Similar numerals of reference are employed to indicate corresponding parts throughout Athe several figures of the drawings.

In drawer pulls and knobs'of ordinary construction it is usual to employ a securing- 6o screw extending through the front portion of the drawer from the rear surface toward the front and engaging a shank formed on the knob or pull, and in other cases to employ small eyebolts extending through the drawerfront and provided at their inner ends with ordinary nuts, the eyes receiving the'ends of handles or pull members. Such fastenings are quickly loosened from constant use and areasourcecf annoyance in using the cheaper 7 a class of furniture.

In carrying out the present invention provision is made for firmly locking the parts, so that it will be im possible for the screw to become loosened or the knob to turn from ordinary use.

.In the drawings, l represents the front of a drawer or similar structure provided with a transverse opening 2. Through this opening extends a securing-screw 3, the head 4 of the 8o l screw being disposed at the rear surface of the drawer-front. The base of the screwhead is flanged, as indicatedat 5, and on its under surface are formed a number of projections or corrugations alternating with 8 5 notches, as indicated at 7. The corrugations may be of any number and of any suitable shape, as shown in Figs. 4, 8, and 9. 0n the inner end of the screw .is placed a washer 8, having inturned prongs or spurs 9 of any de- 9o sired number which embed themselves in the woodwork when the screw is driven home, and the upper or outer face of said washer is provided with corrugations and notches, as indicated at 9', in order to engage the corre- 95 spending notches andcorrugations onthe inner face of the screw-head, and thus prevent the screw from turning. The screwenters the rearwardly-extended portion of arknob l0 or stud ll of the drawer-pull, and in the roo latter case the stud is prevented.v from turning by the pull-handle yl2, as shown in Fig.

5, so that it will be unnecessary to employ any auxiliary means for preventing turning of the stud, and when once the screw is tightly turned the studs or prongs will embed themselves in the wood, while the interlocking of the notches and corrugations formed in the adjacent faces of the screw and washer will prevent the screw from working loose.

Vhen used in connection with a knob, it becomes necessary to provide some means for preventing turning of theknob under careless handling, and for this purpose the inner end of the knob is provided with a boss 13, that is non-circular in form, and while in the present instance it is shown with two diametrically-opposed flattened sidesllc it is to be understood that the shape may be triangular, rectangular, or any form that is not circular. This boss tits within an opening formed in a washer 15, the washer being dished and its peripheral flange having a plurality of studs or prongs 16, that enter the wood at the front of the drawer. The receiving-opening for the boss is formed by a suitable die, and the side walls of the opening are turned inward to form flanges 17, preferably of a depth about equal to that of the periphery flange 15, so that they may come into contact with the front of the drawer, and thus prevent crushing of the washer while the screw is being tightened and at the same time by binding against the front of the drawer aid the studs 16 in preventing turning movement of both the Washer and the knob. This washer is formed of steel, iron, or other cheap metal, and in order to conceal the same I employ a second cover or washer 18, formed of light brass or other suitable metal and held in place bya flange at the rear end of the knob. This finished washer is also provided with an opening corresponding -in shape to the boss 13, and is therefore held from turning, so that noneof the parts can work loose and the knob cannot become accidentally detached.

Having thus described the invention, what is claimed is- 1. In a securing device for furniture-ttings, a revoluble threaded member provided on its inner face with projections',and a dished washer having corresponding projections on its outer face, the inner face of said washer being provided with a plurality of wood-engaging spurs at its flanged margin, the spurs serving by engagement with the wood to prevent turning movement of the washer in either direction.

2. The combination with a knob having a non-circular boss, of a dished washer having peripheral wood-engaging spurs, anda bossreceiving opening at the center of the washer, one or more of the walls of said opening being turned inward to strengthen the washer, and means for securing the knob in position.

3. In combination, a knob having a noncircular boss, a dished washer having a eentral boss-receiving opening the walls of which are turned inward for a dist-ance corresponding to the depth of the Washer, integral spurs or prongs at the periphery of said Washer, and means for securing the knob in position.

4. In combination, `a knob having a non-circular boss, a reinforced washer having abossreceiving opening and provided with edge spurs or prongs, a linished disk covering the locking-washerand held in place by the knob, and means for securing the knob in position.

5. In combination, a knob having a noncircular boss, a locking-washer having a noncircular opening the Walls of which are turned inward to reinforce the washer, peripheral spurs or prongs on said washer, a washer of finished metal held in place against the lock-v ing-washer at the rear portion of the knob, a screw adapted to a threaded opening in the knob and provided with a corrugated head, and a dished washer having corrugations interlocking with those of the head, the flanged peripheral portions of lsaid dished washer having a plurality of projecting wood-engaging spurs.

In testimony that I claim the foregoing as my own I have hereto affixed my signature inV the presence of two witnesses.

DANIEL W. TOVER.
