Application August 22, 1940, Serial No. 353,714

1 Claim.

This invention relates to improvements in nonvibrating pulls for radios and the like.

The main objects of my invention are:

First, to provide a novel nonvibrating door or drawer pull, especially designed for the cabinets of radios and like structures.

Second, to provide a pull or like wall handle member adapted for the uses stated having simple, inexpensive provisions for preventing vibration thereof, while still enabling the same to be readily mounted on a radio cabinet or panel, and also one which is attractive in appearance.

Further objects relating to economies and details of my invention will appear from the description to follow. The invention is defined in the claim. 7

A structure embodying the features of my invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a fragmentary view in front elevation illustrating a handle pull for a radio cabinet or other similar structure embodying my invention.

Fig. 2 is a fragmentary view in side elevation further illustrating the pull of Fig. 1.

Fig. 3 is an enlarged fragmentary view partially in section on line 3-3 of Fig. 1, illustrating details of my invention.

Fig. 4 is an enlargedfragmentary view partially in vertical section still further illustrating the structure of my invention.

Fig; 5 is a side view partially broken away and in section illustrating a pendant type pull in accordance with a modified embodiment of my invention.

Fig. 6 is a fragmentary view in section on line 6-8 of Fig. 5, further illustrating the construction of that embodiment.

It ha been found that certain cabinet type radios or radio-phonograph combinations are subject to the objection that the ornamental hardware associated therewith, for example, door or drawer pulls and the like, tend to have vibration set up therein in the operation of the radio or other device, with resultant rattling which is often times audible and interferes with the enjoyment of the program being received. It is therefore the purpose of the present invention to provide a pull having means embodied therein for damping out and preventing such vibration. The structure of my invention is simple and inexpensive in nature and capable of being assembled on the cabinet in the same manner as well known types of drawer or door pulls.

Referring to the drawing, the reference numeral l illustrates a radio cabinet drawer front panel or other similar panel surface on which it is desired to mount the pull, the ornamental escutcheon 2 of which is generally indicated by the reference numeral 3. The panel I is provided with an opening 4 extending therethrough to receive posts 5 constituting a part of the pull, which posts are disposed in suitable holes in the escutcheon and are shouldered at 6 for engagement with the escutcheon to hold the same in place. In accordance with conventional construction, the posts are provided with lateral openings or recesses 1 extending partially or wholly therethrough externally of the escutcheon for the reception of pintles 8 on the handle or grip element 9.

It is at this point, namely, the point of reception of the handle pintle by the post, that the unwanted vibration is set up, and in order to eliminate the same I provide each of the posts with an axial bore l extending from the rear thereof into communication with the lateral opening 1, which bore receives a coil compression spring ll bearing against the pintle 8 at one end and at the other against a securing screw l2 employed in fastening the pull to the cabinet, the posts being internally threaded for engagement with this screw. The screw carries an enlarged head provided with a washer I3 bindingly engageable with the interior of the panel in accordance with well known practice.

When the pull is assembled on the cabinet panel and the screw tightened to draw the same 35 into place, the coil spring II is simultaneously compressed and forced against the rear of the handle pintle in the manner clearly illustrated in Figs. 3 and 4, thereby effectively damping any tendency for the handle of the pull to vibrate or set up an objectionable rattle. The handle is by this means also held in its position of adjustment as shown in Fig, 2.

In Figs. and 6, I illustrate a modified embodiment of my invention for a pendant type pull, wherein a sheet metal loop-like mounting or post member I4 is threadedly connected to the securing screw l5 at its rear end and at its front end receives a stirrup-like pivot portion I6 of the pendant handle or grip IT. A coil spring i8 is disposed in the recess between the screw and the pendant stirrup engaging the latter to prevent vibration in the same manner as in the modification of Figs. 1 to 4. When assembled, the securing crew simultaneously 55 compresses spring l8 and draws the mounting member [4 to operative position internally oi an opening (not shown) provided in the cabinet or other panel to receive the same.

I have illustrated and described my improvements in embodiments which are very practical. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:-

A handle pull for a radio or like cabinet panel, comprising an escutcheon adapted to be mounted on the front of the panel and having an opening in alinement with a panel opening, a post telescopingly receivable in said openings having a shoulder restrainingly engaging said escutcheon to maintain the post in operative relation to the escutcheon, said post having associated therewith a securing screw engageable with the rear side of the panel to hold the post and escutcheon in place thereon, and having an axial bore therein threaded at its rear for engagement with the screw and a transverse recess communicating with the bore and pivotally receiving a handle pintle, said recess confining said pintle to a position spaced forwardly of and out of engagement with said escutcheon, and a coil compression spring disposed in said bore and engaging said pintle and screw at its opposite ends whereby to prevent vibration of the pintle when compressed by the screw.
