Application filed August 7, 1916. Serial No. 113,448.
comprehensive specification and exposition, the same home; such as Wlll enable others to make and use the same with exactitude.
The object of my present invention, broadly stated, is to produce new and useful machine elements which will be strong and durable in construction, neat and attractive in appearance, simple in arrangement and operation, compact as to space required therefor, which will greatly facilitate the accuracy of the work performed by the ma chine in which it is incorporated, and which can be manufactured and utilized at a comparatively low price.
More specifically stated, my object-is to provide a spindle adjusting mechanism for lathes, grinding machines, and other similar tools, whereby the usual end play of the spindle or shaft will be entirely eliminated, and by which the usual wear incident to such devices may be compensated for, thereby permitting absolute accuracy in the work produced thereby.
Other minor objects and particular advantages of the invention will be observed and brought out in the course of the followin g specification, and that which is new will be correlated in the appended claims which terminate this specification.
The preferred means for carrying out my invention in a mechanical and a practical manner is shown in the accompanying drawings, in. whichFigure l is a longitudinal central vertical section of the invention, showing the spindle in full-line elevation.
Fig. 2 is an end elevation of the parts shown in Fig. 1.
Fig. 3 is a detail plan view of the pulley and the adjusting collar connected thereto.
Fig. 4 is an elevation of the adjusting colla-r alone.
And Fig. 5 is a perspective view of the set-pin alone.
Similar indices denote like parts throughout the several views.
In order that the construction, the operation, and the advantages of my invention may be more fully understood and apprec a e l w l new t k 1? a detail-ed d ption thereof, in which I will set forth the same as briefly and as comprehensively as possible.
Referring now to the drawings in detail, numeral 1 denotes the base of a machine, which has two upwardly extending standards 2 and 3, carrying the respective heads 4 and 5, which latter have a horizontal aperture therethrough, which are in alinement with each other, and in which are secured the respective bearings 6 and 7.
Extending through and fitting in said bearings is the spindle or shaft 8, which extends beyond the bearings at each end thereof. In this instance the ends of the spindle are reduced in diameter, as at 9 and 10, and the major outer parts of the reduced portions are threaded, as at 11 and 12, to provide means for securing" an emery wheel 13, or other tool, on one or both ends of the spindle, as bymeans of the disks ab and c-Z, to be clamped in place by means of the respective nuts 14 and 15, as shown, or otherwise if desired.
Numerals 16 and 21 denote caps which fit around the spindle 8 and close the outer ends of the apertures through the heads 4: and 5, pressing the felt rings 18 and 23 in contact with the bearings 6 and 7 and also into contact with the spindle 8.
In like manner the fiber washers 17 and 20 close the inner ends of the apertures through the heads, pressing the felt rings 19 and 22 in contact with the bearings and with the spindle.
Numerals 24 and 25 denote oilers for the spindle bearings.
-The invention proper comprises the fol lowing devices: Letter A denotes the belt pulley which is rigidly secured on and around and concentric with the spindle by means of the pin B, or otherwise, the said pin being inserted. at right-angles through the central portion of the pulley and through the shaft as indicated.
A flange D extends out from around one end of the pulley to prevent a belt from sliding off. The flanged end of the pulley contacts with the fiber washer 17, or some other stationary part of the machine. the opposite end of the pulley there extends the exteriorly threaded nipple E, whichis integral with the pulley and it extends in an axial direction to near the fiber washer 20, or some other stationary part of the machine, The said nipple is of less diameter From than thebodyof thepulley,thereby forming a square shoulder as shown.
Letter F denotes the adjusting" collar,
which is in the nature of a round nut, and it is adapted to be screwed on the nipple E V and extends from said shoulder at the in'tersectic'in' of the pulley and the nipple to" near the fiber washer 20. .Formed in the face of the collarF are sockets G to receive the prongs of a spanner wrench whereby the collar may be rotated independently of the pulley.
The locking wwcmS.-Formed in the center of the periphery of the collar F, and at right-angles to the spindle, is the in'teri'o'rly threaded socket H which is slightly deeper than' is the length of the set-screw I which is adapted to'be screwed therein. The socket adapted to slide in the aperture J and hav- 5 ing a heart L which is slightly less than the diameter-of the socket H in which it is 10- cated, The inner end of the set-pin is provided with threads M which are adapted to fit the threads of the nipple E when the setpin' pushed inward to ,its limit.
p v Modde opera halt.
From the above it will beapparent that by loosening the set-screw I the collar .F
maybe turned uponthe nipple E, thereby contacting the right-hand face of the collar against the fiber washer 20 and contacting the left-hand face of the pulley against the fiber washer 17 thereby taking up all .bf the end play or endwise movement of the shaft. -lifter the above mentioned adjust? ment has been made then the set-shrew I should be run in or tightened, which will press the pin K'inward thereby engaging the threads. M securely in mesh with the threads of the nipple E, and without injury thereto, which manifestly will lock the collar against inadvertent movement.
"Itis to be understood that Ireserve the right to make minor changes in the details of the invention, from that herein shown, and that the invention proper is not to be limited to the type or character of machine which is herein shown therewith.
'Having now fully shown and described my invention, whatI claim and desire to secure by Letters Patent of the United States, is
' i Gaines tr this patent may be obtained for 1. A spindle adjusting mechanism comin combination with two bearings anola spindle mounted therein, a pulley rigidly secured to the spindle and located between said bearings, a threaded nipple projecting from one end of the pulley, and a collarthreaded around on said nipple, all substantially as shown and described.
2. A spindle adjusting mechanism comprising in combination wlth two bearing and a spindle mounted in the bearings, a pulley secured around the spindle and located be tween said bearings,- a. nipple projecting from one end of the pulley, a collar threaded around on said nipple and adapted to move in an axial direction toward and from the pulley, and means for locking the pulley in its adjusted position, all substantially as shown and described.
3. In combination with two spaced apart stationary elements and a shaft revolubly mounted in. said elements, a pulley secured around said shaft and located at one end in contact with one of said elements, a threaded V nipple projecting in an axial direction from the other end of said pulley, a collar threaded around on said iiipplc and adapted to project beyond the free end thereof to contact with the other element, all substantially as set forth.
4. In combination two spaced apart stationary elements and a shaft revolubly mounted in said elements, a pulley secured around saidshaft and between said elements and adapted to contact with one of said elements, a projection extending from one end of the pulley and in an axial direction and tonear the other one of said elements, a collar surrounding said projection and adapted to be moved parallel with the shaft and to contact with the otherone of said elements, and means for locking said collar to the projection.
5. A device of the character set forth, comprising in combination with a spindle, a pulley surrounding the spindle, means for securing the pulley to the spindle, a projection extending in an axial direction from one end of the pulley, a collar surrounding the projection and adapted to be moved endwise toward and from the pulley, and means for locking the collar upon the projection.
In testimony whereof I have hereunto subscribed my name to this specification in the presence of two subscribing witnesses.
