KEY CONSTRUCTION Original Filed Jan. 25, 1928 Patented Nov. 1, 1932 STATES CHESLEY '1. SMALL, ST. LOUIS, MISSOURI KEY CONSTRUCTION Original application filed. January 25, 1928, Serial No. 249,385. Divided and this application filed August 3,
My invention relates to a key construction and in the form shown is adapted for use in connection with a roller plunger support such as shown in my application Serial No. 249,385 filed January 25, 1928, of which the present application is a division.
In the accompanying drawing, which illustrates one form of key construction made in accordance with m invention, Figure 1 is a vertical section; Ff re 2 is a side elevation; and Figure 3 is a slightly enlarged perspective view of the key. 7
The stem 1 of the plunger, the lower part only of which is shown, is provided with threads 2 and a key way S. A ll-shaped bracket composed of a cross bar 4 and a pair of arms 5 has formed in the cross bar an unthreaded aperture 6 of such diameter as to allow the stem 1 to slide longitudinally therein. Formed in the bracket is a cylindrical opening 7 to receive the cylindrical part 8 of a lroy 1 having a square head 9 engaging the key way 8 to prevent rotation of the stem relative to the bracket.
Surrounding the stem above the cross bar is a nut 10 of hexagonal or other form suitable for engagement with a wrench. Below the cross bar is a second nut 11 having formed in its periphery a number of openings 12 which may be engaged by an adjusting rod thrust between the arms 5 and so rotated. This construction permits of exact adjustment of the bracket longitudinally of the stem and hence the exact positioning of the can carried by the plunger. Secured in the lower ends of the arms 5 is a short shaft 13 on which is mounted a roller 14:.
In the preferred form of the key shown in Figure 3 the diameter of the cylindrical portion 8 is equal to the distance across the head 9 from face to face, so that the key may be formed from square studs by turning or otherwise reducing a portion of the stock to form the cylindrical part 8. The key being positioned from the interior of the aperture 6 cannot become displaced while the stem 1 is in the aperture. Owing to the form of the part 8 the key is capable of pivotal movement and consequently the square part can accommodate itself to any unevenness of the Serial No. 383,325.
key way so that binding between the stem and its bearing is prevented.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. In a device of the class described, the combination with a shaft provided with a key way, of a member having a bore in which said shaft is movable longitudinally, a lateral bore in said member intersecting said first named bore, and a key comprising a cylindrical stem and a rectangular head, said head having sliding engagement with the key way, said stem being located in the lateral bore and having pivotal movement therein to compensate for unevenness in the key way.
2. In a device of the class described, the combination with a threaded shaft provided with a key way, of a member having an unthreaded bore in which said shaftis movable longitudinally, a lateral bore in said member intersecting said first named bore, a key comprising a cylindrical stem and a rectangular head, the stem of said hey being positioned in said lateral bore and the head thereof in said hey way, and a pair of nuts engaging the threads of said shaft, one being disposed at each side of said member, whereby the rotation of said nuts will cause longitudinal movement of the member relative to the shaft but the key will prevent relative rotary movement of said parts.
In testimony whereof, I hereunto afix signature, this 30th day of July, 1929.
CHESLEY T. SMALL.
