Application'flled December 31, 1924. Serial no. 759,033.-

This invention relates to handles an automobile doors, although it is,

(1 parused for of course,

'not' limited thereto but may be used for mak-.

ing similar handles, and it has for an object to provide an improved method of mounting in these handles an insert of a contrasting color to the color of the body of the handle to give a neat and attractive appearance,

and also in some instances to strengthen thehandle and assist in the securing together of the parts comprising the handle.

With the foregoing and other objects in view, I have devised a method for making handles, the steps of 0 made by this method are illustrated accompanying drawing,

which and articles in the similar reference characters being employed throughout the various figures to indicate corresponding elements. In this drawing,

' the side edges of theslab by these flanges are substantially at right Fig. 6 or In carrying out my inventiona slab or a strip 19 of the material is provided which contains approximately the amount or .a somewhat greater amount than is required to fill the groove in the handle when completed, this slab being somewhat the shape shown-in Figs. 4, 5 and (Sand made of a material which is hard at ordinary temperatures but is relatively soft or plastic when heated, such for instance as This slabis placed in the channel between the flanges 17 as shown inFi 6 when the hard material is heated, and therefore, is in a relatively soft or plastic condition. The flanges 17 are then pressed inwardly into means, such as the dies 20'of a power press, to substantially the position sho" 3 so that their free edges overhan the inner side edges of the slab and are-a o pressed into this slab as it is relatively soft and plastic. This pressing of the flanges against the sides of the slab causes the plastic material to completely fill the groove and it is then allowed to harden by cooling, after which it is substantially in one piece with the metal bar.

.ferent construction in which the insert is mounted in exactly the same way. 'In this construction. the cross bar of the handle comprises a sheet metal channel member 21 with the free edges of the side members 22 providing inturned flanges 23, the channel member being secured to the latch operatin spindle 24 by means of a metal bar 25 rigi ly secured to-the end of the spindle, as by riveting it thereto, the spindle passing through an opening 26 in the channel member. 'VVhen it is first formed the cross sec-' I tion of the channel member is substantiall xtion shown in Fig. 8-, firmly that shown in Fig. 7 The insert slab 27 is 7 be finished by, grinding and polishing. In.

this case, however,

theinsertis pressed tight- 1y about the bar h 25 and securely fastens it 1 within the channel member, making a. rigid mesmeand strong connection between the cross bar of the handle and the s indle.

It will be apparent description that this method of appl ing the insert to the handle is much simp er than rom the foregoing 30 the old method of vulcanizing 1t in the channel, may be performed much more rapidly and with less apparatus and therefore, may be made at much less cost.

Having thus set forth the nature of my invention, what I claim is:

The method of making a door handle or the like which consists in forming the handle.

with a groove in itsfaee with flanges on the opposite sides of said groove, providing iln1 the groove a heated slab of a material w is hard at ordlnary temperatures and plastic when heated, pressing the flanges against the opposite side edges of the plastic slab by pressure directed edgewise of the slab only, and allowing the 'slab to harden by cooling, I, g Y
