SET-SCREW.

SPECIFICATION forming part of Letters Patent No. 791,548, dated June 6, 1905.

Application led Hay 23, 1908. Serial No. 158,437- I To all whom it may concern:

Be it known that I, MAx H. FISCHER, of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvementsl in Set-Screws; and I do hereby declare the following to be a full, clear, and exact description of the same,

reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to improvements in set-screws, and has for its object to provide an article that can be readily and cheaply manufactured, but which will obviate many of the diiiculties of manipulation that have characterized the use of former devices. The ordinary set-screw formed by cutting threads upon the outer surface of solid cylinders of metal and providing One end thereof witha shallow slot or recess. for the key or other instrument by means of which it is adjusted has been found to have as its chief objection a tendency to become jammed either from rust, mutilation, orthe lodgment of foreign substances inthe tapping, and the means provided have proved inadequate to effect its immediate removal. Furthermore, when once f broken or crushed yin its adjusted position it has required a large expenditure of time and labor to extricate the fragments. Therefore I have' devised an article which effectually eliminates these difficulties, as the force exerted to cause its removal is directly applied throughout its whole length, which equalizes the strain anddissipates any tendency it may` have to twist or break; and my device is further designed to provide a simple and 4convenient. method of locking the screw in its ad-v justed position by using it in conjunction with another in such a manner that both maybe easily released witlfout necessitating the separate removal of either.

1n the drawings, Figure 1 is a'perspective view of the screw. Fig. 2 is a cross-sectional lview of' a shaft and hub to which the screw is applied`with the latter in process of -adjustd ment, and Fig. 3 is a similar view showingthe method of Operating the locking connection.

Similar reference-numerals in the three figures indicate similar parts.

The device consists, essentially, of a hollow engaging screw 1, closed at one end and provided with an aperture 2, which Ihave shown hexagonal in shape to conform as near as possible with the contour of the piece without weakening it, though it may be of any anguwrench inserted therein. The closed end is beveledat 3 and provided with either a convex or concave face 4, accordingly as adapted to engage a flat or rounded surface. The locking member 5 is similarly constructed, but is 0pen\at both ends and has the aperture extending throughout its entire length. The inner end of the locking member and the outer end of the nut are each provided with the attened faces, as shown, so that as the former is forced into engagement with the latter there will be considerable frictional engagement between the abutting faces, which will serve to hold both the nut and the locking member in position. v v

The method of using the device is as follows: The locking member is slipped upon the shank of a mandrel or key 6,` similar in crosssection` to its interior and adapted to engage therewith, and the latter isthen inserted in the aperture in the member'l, when both are driven together until the latter forms a/bite with the surface-to be engaged. The key is then partially withdrawn, as shown in Fig. 3, until it engages with the locking membe/Il only, when the latter is independently driven into firm contact with theupper surface of the engaging member, securing it in its position. In releasing the connection/the locking member is first started until the keyshank is permitted to operate in the aperture in the engaging member, when vboth may be withdrawn either totally or partially. I

It will be understood that I- do not limit my.

lar or irregular form that will not admit ofL n the free rotation of ay similarly-shaped key or self to a set-screw of two-parts only, as any number may be used in series and locked suc-- A set-screw composed of two exteriorly-,

threaded sections, one of said sections having en irregular aperture extending ltherethrough and the other an raperture therein adjacent thefirst section, said sections having on their proximate ends faces adapted to frictionally IO engage with each other;

MAX H. FISCHER.
