JOHN J'. MILLER, OF NEW YORK, N. Y., ASSIGNOR TO PERFECT WINDOW REGULATOR COMPANY, OF NEW YORK, N. Y., A CORPORATION OF MAINE.

HANDLE CONSTRUCTION.

Application filed March 81, 1922.

To all whom it may concern:

Be it known that I, JOHN J. Minnnn, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Handle Constructions, of which the following is a specification.

My invention relates to rotatable handle or crank members and more particularly to the manner in which the member is mounted and held on a plate or wall or' other support.

In accordance with the invention the ro tatable handle or crank comprises two parts to wit: a bearing member and a handle member proper adapted to be rotated on the bearing member, the bearing member being mounted and secured to the plate in the novel manner and by the novel means hereinafter described.

The principal object of the invention is the production of a construction permitting the bearing member to be effectively and expeditiously secured to the wall or support while permitting free rotation of the handle or crank member.

In the accompanying drawings showing a practical embodiment of the invention:

Fig. 1 is a bottom plan view of my improved device.

Fig. 2 is a section taken therethrough (partly in. elevation).

Fig. 3 is a front elevation of the wall to which the device is secured.

Referring in detail to the several figures of the drawing:

1 indicates a metallic plate or other support to which the device is detachably secured. This plate may carry mechanism to be operated by rotation of the handle or it may be the wall of ahousing containing such mechanism. The plate 1 is depressed to form an annular neck 2 or other analogous upstanding flange provided with an opening 3 in the upper wall 4 thereof and two diametrically disposed L-slots 5 in the side wall thereof each terminating at its inner end in a notch 6. It will be noted that the vertical leg of the L-slots extends upwardly through the upper wall 4 of the neck 2 or in other words that said vertical leg is out both through the upper wall and I side wall of said neck.

7 indicates an annular hollow bearing Serial No. 548,470.

member which is provided with holes or openings 8 therein adapted to receive a spanner or other suitable tool to facilitate the rotation of said bearing member when so desired. The bearing is interiorly screwthreaded adjacent its lower end and it is provided with an annular shoulder 9 adjacent its upper end. 10 indicates the shank of a handle carrying an operating knob 11. The body of the handle is indicated at 12 and it is cast within the bearing 7 and around its shoulder 9 in such manner as to prevent removal of the handle from the bearing although permitting free rotation of the same on said hearing. The body 12 is provided with a squared opening 13 therein adapted to receive the squared end 14 of a cylindrical shaft 15 which extends through the opening 3 of the upper wall of a collar and which may be connected with a sprocket or other device 16 adapted to be actuated upon rotation of the handle 10. If so desired the opening 3 may provide a support or bearing for said shaft 15.

In order to effectively hold the bearing to the plate or support I have provided a hollow, continuous or non-split nut 17 adapted to loosely fit over the neck 9. and having lugs or ears 18 diametrically dis posed and projecting inwardly therefrom. The nut is placed on the neck 2 with the lugs or cars 18 in alignment with the vertical legs of the L-slots and it is then pressed downwardly and rotated. the lugs or cars being guided and riding in said slots until they are brought to rest, in an obvious mannor, by engagement with the inner walls of the horizontal legs of said slots. The bearing member is then screwed tightly on to the nut, its continuous rotation acting. as is manifest, to draw the lugs or ears upwardly into the notches 6 to effectively and detachably lock the device to the plate or support 1 and prevent movement of the bearing member in any direction.

What I claim as my invention is 1. An article of manufacture comprising a support. a hollow bearing, a rotatable member mounted thereon and a continuous exteriorly screw-threaded nut within said bearing on which said bearing is screwed. said nut being detachably locked to said support.

2. An article of manufacture comprising a support, an annular upstanding flange thereon. a bearing, a rotatable member mounted thereon and exteriorly screwthreaded means encircling said flange and locked thereto and to said bearing for holding said bearing to said support.

3. An article of manufacture comprising a support, an annular neck on said support provided with a slot therein, a nut encircling said neck and provided with a lug received by said slot, a bearing screwed on said nut and a rotatable member mounted on said bearing.

4. An article of manufacture comprising a support, an annular neck on said support provided with a slot therein, a nut encircling said neck and provided with an inwardly projecting lug thereon received by said slot, a hollow bearing screwed on said nut and enclosing said nut and neck and a rotatable member mounted on said bearing.

5. An article of manufacture comprising a support, an annular neck on said support provided with a slot therein, an upper wall on said neck provided with an opening therein, a nut encircling said neck and having a lug entering said slot, a hollow interiorly screw-threaded bearing screwed on said nut and enclosing said nut and neck, a rotatable member mounted on said bearing and a shaft extending through the opening in said upper wall and operatively connected with said rotatable member.

Signed at New York, in the county of New York and State of New York, this 29th day of March, A. D. 1922.

JOHN J. MILLER
