FURNITURE-TIP.

Application led April 10, 1915.

To all 'whom it may concer/n .'y

Be it known that I, FREDERICK HACH- MANN, a citizen of the United States, and residing at St. Louis, in the State of Missouri, have invented a. certain new and useful Improvement in Furniture-Tips, of which the following is a specification.

This invention relates to tips, and more particularly, to tips for furniture, such as chairs and the like.

One of the forms of furniture tips now onthe market has prongs formed integral withthe head forming the tip. Unless such a tip is made of heavy metal, it will dent when it is hammered on the tipped article. lVhen, however, this tip is made of heavy metal, the prongswill, of course, be heavy, and this is liable to cause the tipped article to split. Moreover, such integral construction has the disadvantage in that the desired glass hardening of the head will cause the prongs to be brittle and, therefore, easily broken. It has been proposed to construct a furniture tip of separate parts forming an integral structure, but such a device is not only complicated and expensive, but is also difficult to attach, and, moreover, rattles when in place.

One of the objects of this invention', therefore, is to construct a furniture tip comprising a head which forms a floor engaging member, and a separate fastener which secures the head to the article.

Another object is to provide a tip which is simple in construction, consists of a few parts, is easily applied, will not split the tipped article, and which is cheap to manufacture.

Further objects will appear from the detail description taken in connection with the accompanying drawing, in which:

Figure 1 is a side elevation, partly in section, of a furniture leg, showing an embodiment of this invention;

Fig. 2 is a bottom view of Fig. l;

Fig. 3 is a section illustrating the method of applying the device;

Fig. 4 is a face view of the head;

Fig. 5 is a side elevation;

Fig. 6 is a side elevation of a fastener;

Fig. 7 is al face view.

Referring to the accompanying drawing, 10 designates the head, which is, in this case, constructed of sheet metal and of con- Specication of Letters Patent.

veX or cupped form. The rim or periphery of this head which bears on the tipped article is Vprovided with one or more short prongs 11. The center of the head is depressed, as shown at 12, to form a fastener receiving portion provided with an oblong slot 13, adapted to receive the fastener, as hereinafter described. The fastener is preferably constructed of sheet metal formed by stamping, and comprises a cupped crown portion 14 having depending prongs 15 so as to provide a shoulder 1G on each side of the prongs. The fastener is adapted to be inserted through the slot 13, and the cupped crown is of such a size as to substantially fill the depression 12, so that the shoulders 16 will bear on the metal in the depression and the surface of the cupped crown portion will stand flush with the conveX surface of the head 10, so as to form a continuation thereof and preserve the unbroken continuity of the active surface of the glide. To apply the tip to an article, such as a chair leg 17, the cupped head is first positionedon the article and temporarily held by tapping the same, so as to cause the short prongs 11to enter the leg. rEhe fastener is then inserted into the slotted depression of the head and driven home, so that the crown of the fastener will be flush with the surface of the head and will cooperate therewith to prevent the tip-head becoming dented or attened. The head will thus be firmly. held in position, and on account of the construction of the fastener having a pair of prongs against which the edges of the slot bear will be held against rotation.

The parts are made of sheet metal formed by suitable dies, and can, therefore, be constructed very cheaply. By making the tip of two separate parts, it can be attached by a central fastener without liability of splitting the article. Since the parts can be made interchangeable, the wearing out part, namely, the head, can be readily replaced. The fastener can be made of a cheap and thin metal, which need not be hardened, so

' that the prongs will not be brittle, while the head can be made of a heavier metal, and this head can be hardened, so as to resist wear.

It is obvious that various changes may be made in the details of the construction without departing from the spirit of this invention. It is, therefore, to be understood that this invention is not tol be limited to the speciiic construction shown and described.

Having thus described the invention What is claimed is:

A furniture tip comprising a one piece cupped metal head adapted to bear at its periphery on the tipped article, said head having a convex outer face constructed and arranged to form the active glide surface of the tip and being provided in said face Witha depressed, slotted fastener receiving portion adapted to bear atits bottom on the tipped article, and an inserted fastener adapted for attaching. said head to said article, and comprising a cupped, smooth surfaced crown portion and a. plurality of prongs, said prongs being disposed for cooperation with the eOlg-{GSV Of said slotted portion to hold the head against rotation and said crown portion being, rcornstructed and arranged to lit Within said depression and seat against the bottom thereof with the outer face of said crown portion standing flush with the outer convex i''acey of said head; whereby said crown portion Jforms, in eHect, a'continuation of the head and cooperates therewith for, preserving the in@ tegrity of the active glidesurface of the tip. ln testimony whereof I ailix my signature this 28d da-y of March, 1915.
