METHOD OF MAKING HANDLES.

Specification of Letters Patent.

Application filed June 11, 1914. Serial No. 844,543.

To all whom it may concern:

Be it known that I, MINARD A. PossoNs, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Methods of Making Handles, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in method of making handles.

The object of my invention is to make a handle of porcelain, metal or other material indestructible by heat and securing therein a screw-threaded attaching rod whereby the handle is attached and at the same time providing a handle having a very neat appearance.

Another object of my invention is to make a handle more especially adapted for gas valves used on gas stoves and in which a sanitary handle is produced having certain details of structure and method of forming hereinafter more fully described.

Referring now to the drawing: Figure 1 is a vertical sectional view of the handle showing the first step in the method of making the same. Fig. 2 is a vertical sectional view similar to Fig. 1 showing a completed handle having the screw-threaded attaching rod secured therein. Fig. 3 is a perspective view showing the handle proper and the screw-threaded attaching rod in a position to be inserted in the handle. Fig. 4 is a perspective view showing my handle applied to the ordinary gas valve used on gas stoves and for which my handle is more especially designed.

Referring now to the drawings in which like reference numerals designate similar parts, 1 represents the handle which is preferably made of porcelain or other indestructible material by heat so that it can be heated in the method of making the handle as will be hereinafter more fully described. My improved handle as shown is of an elongated elliptical form having a central opening 2 extending from one or the end inwardly nearly entirely through the handle as shown in Figs. 1 and 2 of the drawing. This opening 2 is of a circular form and is provided with a series of longitudinally extending radial grooves 3, the objects of which will be later described.

My improved attaching means for the handle consists of a rod 4 having the threads 5 at one end and the opposite end smooth as indicated at 6, and adjacent the end the said smooth portion is provided with a series of fins 7 corresponding in number to the radial grooves 3 and adapted to enter the same whereby the rod is held within the opening 2 of the handle 1 against rotation. The rod 4 is secured in the handle in the method hereinafter set forth and forms a handle whlch is sanitary as it has a smooth outer end on which dirt and grease can not collect and at the same time providing a handle having a neater appearance than those heretofore used. The screw-threaded portion 5 of the rod 4 is screwedinto an opening in the turning plug 9 of the valve 10 and thus a very neat valve is produced as clearly shown in Fig. 4 of the drawing.

Heretofore in the manufacture of handles for gas valves for gas ranges, the bodv portion 1 had the opening 2 extending entirely through the handle and was secured to the valve stem 9 by a screw passing through the opening entirely through the handle and having a head at the end thereof which does not form as neat appearance as the one herein described and at the same time the head of the screw forms a place where dirt will collect and thus forms a handle hard to keep clean.

In the method of forming my improved handle the body portion 1, as heretofore described, is made preferably of porcelain or other indestructible material and is held in a vertical position as shown in Fig. 1. While in this position a small billet of lead 11 or other soft metal is dropped into the upper end of the opening and passes downwardly in the lower end thereof. The attaching rod 4 is then placed in the opening 2 with its lower end resting upon the lead billet. The body portion 1 of the handle is then heated to a temperature to melt the lead billet 11 and the attaching rod 4 is forced downwardly through the melted lead which forces the lead upwardlv around the rod above the fins 7 and outwardly into the grooves 3. The handle is then allowed to cool and molten lead will adhere to the inner shown in Fig. 2 of the drawing. The billet 11 is of such a size that when melted the metal will be forced upwardly to a point opposite the lower ends of the threaded portion so as to enter one or two of the threads and thus more securely hold the rod within the handle.

Applicant is aware that it is old to pour lead into different articles such as door knobs, and the like for securing a spindle therein, but the herein described method of heating the handle for locking the securing means therein has been found more effective and practical, and at the same time forming a handle having a neat appearance and one which is more sanitary.

Having thus fully described my invention what I claim and desire to secure by Letters Patent is: V

1; The herein described method of forming a handle consisting in first placing a soft metal in a recess in the body portion of the handle, second heating the handle to melt the soft metal and forcing an attaching member into the molten metal and holding it therein until the metal 'hardens.

2. The herein described method of forming a handle consisting in first placing a soft metal billet in the lower end of a recess in the body portion of the handle, heating the handle to melt the'billet, forcing an attaching member having outwardly extending enlargements into the molten metal and holding it therein until the metal hardens.

3. The herein described method of forming a handle consisting in placing a soft metal billet in an elongated recess in the end of the body portion of the handle, heating the handle and melting the billet, forcing an attaching member in the recess into the molten metal and forcing the metal upwardly around the attaching member and holding it therein until the metal hardens.

l-. The herein described method of forming a handle, consisting in first placing a soft metal billet in the lower end of a recess in the body-portion of the handle, placing the attaching member in the handle and resting upon the billet, heating the handle to melt the billet arid forcing the attaching member into the soft metal and holding it therein until the metal hardens.

5. The herein described method of forming a handle, consisting in placing a soft metal billet in an elongated recess in the end of the body-portion of thehandle, plac-.

dle and melting the billet and forcing the attaching member down into the molten metal and forcing the molten metal upwardly around the attaching member, and the size of the billet being such as to cause the molten metal to rise to predetermined point.

6. The herein described method of forming a handle consisting in first placing a soft metal billet in a recess in the body portion of the handle, placing an attaching member in the recess in engagement with the billet, heating the handle to melt the billet and then forcing the attaching member into the molten metal and holding it therein until it hardens.

7. The herein described method of forming a handle consisting in placing a soft metal billet in a recess in the end of the body portion of the handle, placing an attaching member having outwardly extending enlargements in the recess and resting upon the billet, heating the handle and melting the billet and forcing the attaching member in the recess into the molten metal and holding it therein until the metal hardens.

8. The herein described method of forming a handle consisting in a body portion of fire resisting material having a recess therein provided with radially arranged grooves; second in placing a soft metal billet in said recess; third, heating the body portion and melting the billet; fourth, forcing an attaching member into the recess in the body portion provided with radial grooves so that the molten metal will be forced upwardly around the attaching member and holding it therein until the metal hardens, substantially as shown and described.

In testimony whereof I hereunto afiii; my

signature in the presence of two witnesses.
