4suitably ,journaled inthe zright handhereafter referred .to ,as the ffront--endl of basevorlfnamellxis hollow shaft .46 carryingat oneenda conventional, comparatively large grinding `,Wheel 48, `preferablybut not necessarily enclosed Within a protecting guard .50, open only` at52 toiallow a portion o'ffthe circumference of ,Wheel 48 to engage apiece of work, specifically, as shown, a
shaft 54 to be ground on its exterior circumference. On the opposite end of hollow shaft 46 is a pulley 56 to which power is com- -municated by means of a conventional belt i of base 34 and this sleeve 46 is selectively securable in non-rotative position by means of a lock or latch 66 reciprocal through said housing 64 against the action of spring 68 from the position shown in Figure 3 to a depressed position in which the lower end port-ion or point 70 of latch 66 enters recess 72 provided for it in the circumference of sleeve 46. Latch 66 is movable as described `by an operators pressing downward, as
shownV in Figure 3 on handle 74, provided for the purpose. It is lockable in the depressed position in notch 72 by, in that position, rotating the handle 74 and consequently the latch until pin 7 6 ceases to be in register with the notch (Fig. 7) provided for it in plug 82 and engages the bottom surface 7 8 of the plug. The entire locking mechanism is, for convenience of manufacture, mounted in this plug which is, as clearly f shown in Figures 3 and 7 screw threaded into an opening provided for it in the eX- terior wall of housing 64. Grinding wheel 48 is rigidly secured upon hollow shaft 46 by suitably threaded conventional nut 86 and pulley 56 is correspondingly held on the hollow shaft by a similar nut 88. The ends of shaft 46 beyond these nuts 86 and 88 are slotted to form tapering screw threaded lingers 90 engaged by laterally tapered nuts 92 and 94 which, when in the position of Figure 3 compress these fingers 90 together and rigidly lock them upon a central, solid shaft 96 carrying at one end-specifically as shown the left hand end-a small grinding wheel 98, capable of use in grinding the interior of work such as cylinder 32. With the construction just described, grinding wheel 98 and shaft 96 are for practical purposes rigid with hollow shaft 46 and therefore rotate with it when the motor 60 drives the hollow shaft and as shaft 96 is rigid with hollow shaft 46, it is necessary to manipulate the entire tool carriage of the lathe in order to reciprocate wheel 98 lengthwise of the axis of cylinder 32 to be worked upon.
ln thc alternative construction of Figure 7,' shaft 100, corresponding in many respects with shaft 96, is provided at its lefthand or working end, as viewed in Figure 7, nwith key ways 102, slidable'upon inwardly projecting keys 104 on the interior of special nut 106 substituted for nut 94 of the preferred construction. In the construction of Figure 7, nut 92 is left so loose that it does not cause fingers 90 to grip shaft 100, or this nut may be entirely omitted without departing from the invention. Shaft 100 is provided at itsy right hand end, as shown in the drawings, with a conventional form of handle 108 by means of which the operator may, while hollow shaft 46 is rotating, and the lathe tool carriage is standing still, reciprocate the shaft 100 through hollow shaft 46, thereby moving grinding wheel 98, being simultaneously rotated through the agency of hollow shaft. 46 and keys 104, forward and backward along the length of work case 32.
The key ways 102 in the solid shaft are wholly unnecessary when the mechanism is to be operated as described in connection with Figure 3 but they may be provided, as indicated in Figure 3 in shaft 96 without departing from the invention and, when this is done, all that is necessary to convert the device from one construction to the other is to substitute nut 106 for nut 94 and provide a handle corresponding in function to handle 108 on shaft 96-this while simultaneously loosening or removing nut 92.
It is obvious that by loosening nuts 92 and 94, the operator may reciprocate shaft 96 through hollow shaft 46 to any position desired for wheel 98 and then 'by tightening the nuts 92 and 94, secure the parts in a new position.
From the foregoing, it will be seen that this invention pro-vides a grinding tool which is practically universally adjustable with reference to the tool carriage of a lathe or the like; that it carries a large wheel for external grinding; a. small wheel for internal grinding; that the latter wheel may be reciprocated while rotating lengthwise of the work being treated either by moving the entire grinding mechanism carried by the tool carriage of the lathe, or by manipulating the grinding wheel itself alone with reference to the driving mechanism. By using the latch 66, the tubular shaft 46 is held stationary so that nuts 88, 94, 86 and 92 may be readily tightened orv loosened for the purposes heretofore described. In actual practice one grinding wheel is wholly removed from the machine while the other is in use; this because their working uses require different speeds and the large wheel would not stand the speed of the smaller wheel without going to pieces.
Having thus described my invention, what l claim as new and desire to secure by Let-ters Patent is:
l. In mechanism of the class described, a support, a hollow tool carrying shaft rotatably journaled in said support, a second tool carrying shaft within and longitudinally movable with respect to said hollow shaft to adjust the posit-ion of the tool carried thereby with respect to said supporty and with respect to the tool carried by said hollow shaft, means carried by and movable with respect to said hollow shaft for vsecuring the two shafts together whereby they may be rotated in unison, .and mea-ns to lock said hollow shaft against movement to facilitate manipulation of the means for securing the shafts together.
2.. In mechanism of the class described, a support, a hollow tool carrying shaft ro'- tatably journaled in said support, a second tool carrying shaft within and longitudinally movable with resp'ect to said hollow shaft to adjust the position of the tool carried thereby with respectto said support and with respect to the tool carried by said hollow shaft, means carried by and rotatable with respect to said hollow shaft for securing the two shafts together whereby they may be rotated in unison, and means to lock said hollow shaft against rotation to facilitate manipulation of the means for securing the shafts together.
3. In mechanism of the class described, a support, a hollow tool carrying shaft rotatably journaled in said support, a second tool carrying shaft within and longitudinally movable with respect to said hollow shaft to adjust the position of the tool carried thereby with respect to said support and with respect to the tool carried by said hollow shaft, means carried by and movable with respect to said hollow shaft for securing the two shafts together whereby they may be rotated in unison, a pin movable into engagement with said hollow shaft to lock the same against movement to facilitate manipulation of the means for securing the shafts together, a spring constantly tending to move said pin out of engagement with said shaft, vand means to latch said pin in engagement with said shaft, said pin, said spring and said latch means all being carried by a member detachably carried by said support.
4. In mechanism of the class described, a support, a hollow tool carrying shaftk rotatablyjournaled in said support, a second tool carrying shaft within and longitudinally movable with respect to said hollow shaft to adjust the position of the tool carried thereby with respect to said support and with respect to the tool carried by said hollow shaft, means engaging and movable with respect to one of said shafts for securing the two shafts together whereby they may be rotated in unison, and means to lock lsaid shaft against movement to facilitate manipulation of the means for securing the shafts together.
In witness whereof, I have hereunto subscribed my name.
