SPECIFICATION forming part of Letters Patent. No. 355,502, dated January 4, 1857.

Application filed July 12,1886,

Serial No. 201,135. (No model.)

To aZZ whom it may concern.-

' Be it known that I, GRANVILLE B. BRON- soN, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Drawer;Pulls; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a perspective View of the socket and spindle secured together; Fig. 2, a longitudinal section of the same; Fig. 3, a vertical section of the cup preparatory to its attachment to the spindle; Fig. 4, a side view of the spindle or bolt; Fig. 5, a vertical section through the die and punch, showing the parts in the position for the striking operation; Fig; 6, the same as Fig. 5 after the striking operation.

This invention relates to an improvement in that class of drawer-pulls in which a socket is secured to the drawer-front, and a handle hinged in the socket so as to fall into a perpendicular position when not in use, but lifted into a horizontal position in pulling out the drawer, the invention relating specially to the construction of the socket whereby it is attached to the drawer-front. In the general construction of these sockets a screw or bolt is attached to the socket by some device, the bolt being a screw adapted to screw into the front of the drawer, or to extend entirely through the front, with a nut applied upon the inside.

The object of the invention is to permanently secure the socket to the bolt without the use of solder, and so as to prevent possible detachment under any ordinary usage; and the invention consists in the construction hereinafter described, and particularly recited in the claim.

I first draw up a sheet-metal cup, at, Fig. 3, the external diameter of which corresponds to the external diameter of the socket. The bolt or spindle by which the socket is to be secured is represented in Fig. 4.. This is usually made from wire of sufficient length to form the body I), and with a head, 0, upon one end. The head is undercut or of conical shape. The bolt and cup are secured together in dies.

A represents the principal an opening through it corresponding in diameter to the external diameter of the cup, and within this die is a follower, B, which may be movable up auddown in the die A, and at its upper end is constructed of smaller diameter than the opening through the die, and of'substantially the same diameter as the interior of the cup, and-below its upper end is a shoulder,'d, distant from the upper end somewhat less than the depth of the cup, and through this follower is a concentric opening corresponding to the body b of the bolt, and so that the bolt may beintroduced through the follower, and so as to leave the head projecting above the upper end or face of the follower; then over the head and follower the cup is introduced, as seen in-Fig. 5, the cup coming to a bearing upon the shoulder, but leaving the bottom portion of the cup above the follower and over the head. Over the follower is a punch, D, which is in diameter substantially the external diameter of the cup. I11 the lower end of this follower is a recess, 6, somewhat smaller in diameter than the external diameter of the cup, but little larger than the head of the bolt. After the cup and bolt have been arran edin the die, as represented in Fig. 5, the follower is struck hard down upon the upper end or bottom of the cup, and, in thus striking the punch D, forces the metal of the cup down onto the head, and because of the recess 0 in the punch the edges of the punch pass below the plane of the head and force the metal of the cup into the under-cut or recess beneath the head of the bolt, as shown in Fig.

6. This striking of the bottom down upon the die, which has with, which toa considerable extent ornaments the head, as well as making a firm connection between the head and socket.

1 am aware that a cup-like blank has been 9 applied to a conical head of a bolt by spinning A by my i iwention the punch may be ornamented upon its face so as to produce a corresponding ornamentation upon the projecting portion or face of the socket, thereby improving the appearance of the cupan effect which cannot be attained in spinning, and can only be produced by the striking operation and upsetting similar articles from the drawingnp or striking dies.

- I do not illustrate the pull complete, as such parts are unnecessary to the understanding of my invention, and are too common and Well known to require illustration or description. I clai'm--- 1 The combination of the spindle constructed with an undercut head with a metal cup, at, the closed end of the said cup struck upon the said head, thereby forming a cylindrical concentric projection on the outer end of the said cup, and the metal within the said concentric projection extending beneath the said head, substantially as described, and whereby in the forming of the said concentric projection around the head of the spindle the cup and spindle are secured together.
