LATCH BEARING.

Application filed August 23, 1922. Serial No. 58$,fi39.

To all whom it may concern Be it known that FRANK EDGAR, a. citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, has invented certain new and useful Improvements in Latch Bearings, of which the following is a specification.

This'invention relates to door locks for automobile bodies. It has for its object an improved form of the vertical rotary spindle type of lock. These locks are not broadly new. The invention here relates to the hearing by which the vertical spindle is held against longitudinal movement, and in which it is allowed a free rotary movement. Ordinarily a rotary spindle of a lock of this type is iournalled in the front plate or cover plate. 1 one of the prior patents the cover plate fits in notches in the spindle to prevent it. from moving longitudinally. It is the object of the present invention to journal and hold the spindle entirely independently of the cover plate and the front plate, This permits the bearing to be a separate small member which maybe made of a moresuitable metal for this purpose, such as brass, which will not rust, and which is recognized as a better metal for bearings and bushings.

In the drawings:

a designates the front plate, 6 the face plate, 0 the sliding bolt, and d the roll-back. On the sliding bolt is an abutment e, adaptperspective of the other part of ed to lee-engaged by the crank portion f, of"

the vertical spindle g. This spindle is retated by the handle h. This much of the construction is old, and some of the features of it are described more particularly in a prior application of Andrew Andersen, #522,986. In that application the bearing for the rotary spindle is formed by corrugations in both the cover plate and the front plate, which engage around the spindle.

In the present invention I employ the corrugation in the front plate designated 2'. In

' this corrugation is fitted the half-sleeve j,

plate, a sliding bolt guided transversely preferably of brass or some other non-rustmg material that forms a suitable bearing metal, and held a ainst longitudinal movement by the shoul ers 7' as shown in Fig. 5. The vertical spindle is then laid in the two sleeves which are placed in the groove 6,

resting on either side of the crank portion 7 of the spindle. Thereupon, the bearing: caps k, of a similar metal are fitted over the outside of the spindle and the lugs m are passed through slots n of the front plate, and turned over or riveted over as shown in Fig. 2. This securely clamps the bearing to the front plate. This obviously provides a desirable bearing to permit rotation, and engaging the crank portion of the spindle, prevents longitudinal movement.

What I claim is: V

1. In a lock, combination of a front thereof, a rotary spindle parallel with. the front plate and perpendicular with the sliding bolt arranged to retract the bolt, and a. bearing therefor, comprising a sleeve abutting against the front plate, and a bearing cap engaging about the spindle opposite the sleeve and secured to the front plate.

2. In a look, a combination of a front plate, provided with slots, a sliding bolt guided transversely thereof, a rotary spinle parallel with the front plate and perpendicularto the sliding bolt, and meansindependent of the other parts of the lock for supporting the same, oomprisingbearing parts in the form of a half-sleeve on one side and a bearing cap on the opposite side provided with lugs that may be pamed through the slots in said front plate and clamped thereto.

3. In a lock, the combination of a housing 5 plate provided with a corrugation, having shoulders formed therein, a bearing sleeve set in said corrugation between the shoulders, a cap clamped over the bearing sleeve,

and a rotary spindle held between said bear- 10c ing sleeve and cap.

4i. In a lock, the combination of a front plate, provided witha depression, a sliding bolt guided transversely thereof, a rotary spindle parallel with the front plate and 105 independent of the other parts of the lock, 110

said bearing comprising a sleeve fitted. into the depression carried by the front plate and.

a bearing cap engaging about the spindle opposite the sleeve and secured to the 'tront 5 plate, whereby the sliding bolt and spindle are clamped to the front plate. I

5. In a lock, the combination of a front plate rovided with slots anda bearing seat,

a. sliding bolt guided transversely on the front plate; a rotary spindle journaled in the 10 bearin seat and located perpendicular to the sli ing bolt, and a bearing cap supported over the bearifi seat and rovided with pontions that may e inserte through the slots in the front plate to clamp the bearing cap to the spindle.

In testimony whereof I aflix 111 Si ature.
