I v e,416,7s 2 a I 1 ADJUSTABLE v-BLooK Paul Valish, Waterbury, Conn. Application May 12, nit-seal; Noi'5e5'3s3 The invention relates to a shaft support or rest, and more especially to an adjustable, v-block for machinists use.

The primary object of the invention is the provision of support, rest or block of this character, wherein the same can be keyed to a machine table, so that a machinist can accurately line a shaft for the truing thereof, without the use of shims or other like parts, and such support, rest or block is susceptible of easy-and quick adjustment for the proper setting of the shaft.

Another object of the invention is the provision of a support, rest or block of this character, wherein the construction thereof is unique and novel, it being readily and easily. applied and removed to and'f'rom the work, and is applicable to varying diameters of shafts for the truing operation thereon.

A further object of the invention is the provision of a support, rest or block of this character, which is simple in its construction, thoroughly reliable and eflicient in purpose, strong, durable, compact, serviceable for various kind of work, and inexpensive to manufacture and install.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which show the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is an elevation of the device constructed in accordance with the invention.

Figure 2 is a top plan view thereof.

Figure 3 is a sectional view on the line 3-3 of Figure 1, looking in the direction of the arrows.

Figure 4 is a sectional view on the line 4-4 of Figure 1, looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail A designates generally the support, rest or block constructed in accordance with the invention and hereinafter set forth in detail.

The support, block or rest A comprises a solid base I 0, having at the lower flat faced portion centrally thereof in a longitudinal direction a key II for fitting in the slot in a machine table (not shown). Upon this base I is built a boxing including the vertical side walls l2, which are of uniform height with respect to each other and. meet the upper face of the said base III, while at right angles to the said side walls are end walls 3 Claims. (01. co -59$ l3, these being united to the side walls inany suitable manner, and have their lower edges elevated from the upper face ofthe base. The upper edge of the'end'walls' I have provided; therein horizontally aligned V-shapednotches l4 opening upwardly therefrom. r

The inner surface of the side walls l2 'ar e beveled as at I5 so as to converge in one direction toward each other, and between the side and end walls l2 and I3 is createda well I6 in which is loosely fitted a centering lifting jack including a turn screw l1 threaded centrally in an adjustable, bearing head l8, which is V-notched in its upper face for accommodating upwardly divergent rest or contact plates I9, these being V-set corresponding to the notch or crotch 20in the. saidhead 18 for the support or resting of a shaft (not shown) to be trucd in a truing machine which is also not shown in the drawings.

The meeting faces of the head l8 conforms to the inner surfaces of the side and end walls l2 and I 3 of the well l6 created by the boxing. The screw I! has its lower spindle end 2| displaceably fitting a recess 22 in the base I 0 provided-therefor. This recess 22 allows for the centering of the head I8 when supporting a piece; of work, as for example a shaft, in the truing. thereof.

Next to the spindle end 2| .of the screw I1 is integrally formed thereon a peripherally socketed turning rim 23 so that a pin or bar can be se- ,lectively engaged with a socket therein for the easy turning of the screw in the adjustment of the head l8 to raise and lower the same for the lifting or lowering of the work held thereby.

Tapped centrally in the end walls It .are horizontally arranged set screws 24, wrench engageable, and one of these screws 24 plays against a gripping plate 25 countersunk in the end wall l3 next thereto, and this plate 25 has contact with the head l8, the plate 25 being held from dropping or displacement by retaining pins 26 from its seat in a vertical direction.

The rim 23 is accessible through openings 21 between the base [0 and the end walls I3, so that the screw I! can be regulated in the adjustment of the head l8, and such access is had with respect to either end of the support, rest or block.

Many times in a machine shop shafts having a number of unequal diameters or dimensions have to be machined. The machinist has toset the shaft in a V-block or blocks and line up the shaft by placing shims under one or the other end of such shaft.

The shims may be one-fourth or one-half inch scrap steel, tin or mere paper, a very flimsy but common method; used in some of the best shops, so by using the device herein described, this method is entirely eliminated.

The device is always looked in place centrally,

and it can be keyed in the machine table slot with which the said device is used.

The sides and ends l2 and I3 are preferably united together by fasteners 28, while the plates are secured in position with respect to each other by fasteners 29, respectively.

From the foregoing itis believedthat the con:- struction and manner of useof the device will be clearly understood and therefore a more extended. explanation has been omitted for the salient v r v Changes, variations and modificationsimay'be" brevity.
