PRESS FOR SEPARATING SHAFTS FROM GEARS AND THE LIKE.
Application filed December 19, .1921. Serial No. 523.481.
To all whom it may concern Be it known that I, PnRoivAL J. OLDER- SHAW, a citizen of the United States residing at Harrington, in the county of Lincoln and State of Washington, have invented new and useful Improvements in Presses for Separating Shafts from Gears and the like, of which the following is a specification. P
The object of my said invention is the provision of a simple and durable press for separating shafts from gears and other elements. mounted thereon, and one possessed of a wide range of utility.
To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.
In the accompanying drawings, forming part of this specification Figure 1 is a view partly in side elevation and partly in vertical section, showing my novel press.
Figure 2 is a front elevation of the same with parts in section.
Figure 3 is a top plan view of the press.
Figure 4 is a section taken in the plane indicated by the line 4-4 of Figure 2, look ing downwardly.
Figure 5 is a. perspective of a special base plate for use in the press frame.
Figure 6 is a perspective of another base plate for use in the frame, it being understood that there are preferably ei ht of the said plates provided for use interc angeab-ly in the press frame, the openings in the iplates varying in size to receive shafts of di erent diameters.
Figure 7 is an enlarged perspective of a member designed for interposition between the screw of the press and the shaft to be separated from a gear or other element thereon, it being understood that six of the said members of different sizes and lengths are provided for use interchangeably in 'th press.
Similar numerals of reference designate corresponding parts in all of the views of the drawings. In Figures 1, 2 and 3 I show a portion of a bench top 1, and on the said bench top 1 is fixed by screws 2 or other appropriate means a bracket 3 the forward portion 4 of which is comparatively thick for the connecframe 6 is provided with a lower cross por tion 7. in which is a bifurcation 8, of a size sufficient to receive the largest shaft on the said plates 13 having kerfs'14 of difier-' ent sizes. I would also have it understood that for special work I may employ plate 13, Figure 5, this plate being peculiar in that its kerf 14 is defined by a flange 15 of less thickness than the remainder of the plate, a rabbet 16 being afforded between the upper side of the frame 15 and the upper side of the plate 13 I Said plate is hardened on account of its being extra thin.
My invention also contemplates the employment of an anti-friction member 17 between the lower end of thescrew shank and the upper end of a shaft such as 18 which is to be separated from a gear or other element 19 thereof. I refer to provide the members 17 in three di erent lengths, and two different sizes for use interchangeably. I also prefer to provide the members 17 in three different sizes for use interchangeably according to the location of the gear 19 on the shaft 18, and it will be noted that each of the members 17 is provided at its lower and upper ends with tapered protuberances 20, one of the said protuberances to take into the socket 12 of the screw, and the other protuberances to take into the socket generally provided in the end of the shaft represented.
arranged in the bifurcation of the base plate and so that the gear 19 carried by the shaft is superimposed on the base plate. An antifriction member is then engaged with and held on the upper end of the shaft, after which the screw shank is fed downwardly and engaged with the protuberance at the upper end of the member 17. The screw is then turned downwardly to force the shaft 18' downwardly through the gear 19'with the result that the gear will .be rendered loose on the shaft and can be readily disassociated therefrom. i
It will be apparent that because of the interposition of the member 17 between the shaft 18 and the screw, a powerful thrust can be exerted on the shaft and yet the screw will be subject to but little torsional friction. From this it follows that the screw can be turned with but little effort on the part of the operator. All wearing parts of the improvement are case-hardened and the press can be made from any material suitable to its use.
l have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear andexact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts inasmuch as in the future practice of the in- A press comprising a frame having a bifurcation for the lateral introduction of a shaft bearing an element from which it is to be disassociated, and also having means to ofier an abutment to said element, a screw bearing in said frame, and an anti-friction member for interposition between confronting ends of the shaft and screw, said member having central tapered protuberances at its ends, and the frame including a bracket'with a threaded aperture for the bearing of the screw, said bracket fixed to and extending laterally from. the frame and adapted to be fixed to an appropriate support.
' lln testimony whereof, ll affix my signature.
