LATCH I OR VEHICLE DOORS.

Specification of Letters Patent, Patented lIfll. 28, 1922- Application filed August 2, 1921.- Serial No. 489,264.

To all whom it may concern.

Be it known that. I, RICHARD V; KAIMER,

' a citizen of the United States, residing at New Haven, in thecounty of New Haven and State of Connecticut, have invented a new and useful Improvement in Latches i'or Vehicle Doors; and Ido hereby declare the following, when taken in connection with the accoi'npanying drawings and the characters of reference marked thereon, tobe a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in- I Fig. l a side view of a handle for vehicle door latches constructed in accordance with my invention and shown as applied to the upper end of the latch-spindle. i Fig. 2 a vertical sectional view of .the

same. I

Fig. 3 a top or plan view of the same.

Fig. 4c a sectional view on the Figure 1.

This invention relates to improvement in latches for vehicle doors and is an improve ment particularly to latches which are operated in part by a pushebutton mounted in a vertically-arranged rotatable latch-spindle, and is an improvement in the device shown and described in an application filed May 17. 1921, Serial No. 470,366.

In the device shown in the said application, the handle was secured to the spindle y means of a frictional clamp. A more convenient means of securing the handle to the spindle is to flatten two sides of the spindle and provide the hub of the handle with two flat faces to engage therewith, and secure the handle to the spindle by a nut, and the object of this invention is to provide means for attaching a handle to a latchspindleand provide an operating push-button which will extend up through the handle, and the invention consists in the con struction as hereinafter described and particularly recited in the claims.

In carrying out my invention I employ the usual latch-spindle 5, which is a vertical spindle adapted to be rotated for the movement of the lock, as in the application above referred to, and around this spindle is a sleeve 6 adapted to be pressed downward by means of a transverse-pin 7 operated by a push-rod 8. In this construction, the upper end of the. spindle is formed on line 44 of central bore for the button.

opposite sides with flattened faces 19 and 10,

and that end is threaded to receive a nut 11 which enters a recess 12 in the hub 13 of a handle 14, this nut having a central opening 15 for the passage through it of a button 16 on the end of the push-rod 5.

Preferably, and as shown, this nut is polygonal, so that it may be readily'applied by suitable wrench and serves not only to I hold the push-button in place but to secure the handle to the end ofthe spindle.

' 'With this construction, the handle is' firmly secured to the spindle, and the pushbutton mounted in the spindle for coaction with the sliding sleeve thereon, and the handle brought down closer to the door casing than was possible in the construction shown in the said prior application.

I claim:

1. The combination with a vertically-arranged, rotatable latch-spindle having its outer end flattened on opposite sides and with a central bore, a push-rod mounted in said bore. and formed with a push-button projecting above-the upper end of the spindle. a handle formed to fit the flattened end of the spindle and formed with a chamber into which thespindle extends, and a nut entering the said chamber and engaging with the upper end of the spindle, the said nut forme'dwith a central opening for the passage of the push-button.

2. The combination with a vertically-arranged rotatable latch-spindle having its outer end flattened on opposite sides and with 'a central bore, a push-rod mounted in said bore and formed with a push-button projecting above the upper end of the spindle, a handle formed to fit the flattened end of the spindle and'iormed with a chamber intowhich the spindle extends, and a nut entering the said chamber and engaging with the upper end of the spindle,the said nut formed with a polygonal head and a passage of the said push- In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

RICHARD v. KAIYMER, Witnessesr RUTH E. BRADLEY, JMAR! J MoanIsoN.
