specificatidh forming part of Letters Patent No. 169,941, dated January 26,1875; application filed December '11, 1814.
To all whom it may concern: I
TEE, of Boston, inthe county of- Suffolk and State of Massachusetts, have invented certain Improvements in Supportin g-Olamps for Rock- Drilling Machines, 850., of which thefollowingmay be set at any inclination desired by turnis a specification:
My invention relates to a universal clamp or joint for supporting a rook-drilling machine, and permitting the same to be adjusted in all required directions; and it consists in the 00111- bination of a' standard, a clamp encircling the same, and a drill-frame provided with a-trunnion mounted in the clamp, as hereinafter de- V cannot be placed and secured.
scribed. v e
.Figure 1 represents a side elevationof a drilling-machine provided with and supported by my clamp; Fig. 2, an enlarged side vie of thesame; Fig. 3, a top-plan view of the same; and Fig. 4, atransverse horizontal section .of the clamp.
A represents a round upright or standard, which will be held in place by stepping its ends in the rock, as shown, or by a suitable frame. 13 1s a band or'clamp encircling the standard-A, and having-one side split or divided, andprovided on its ends with two arms, a, which extend outward parallel with=each other-each arm. having a hole made trans.
versely through it, as shown in Fig. 4. 0 represents the frame on which the drilling mechauism-is mounted, provided on one side with a horizontal trunnion, d, which extends through the holes in the two. arms a of the clamp B, as shown. .D represents a bolt passed centrally through the-trunnion, from the frame outward, and provided on its outer end with a washer,
e, and a nut, f, as shown in Fig.4. The washor e bears upon the side of the clamp arm (1.,- and the trunnion dis made of such length that a small space exists between its end-and the washer, as shown in Fig. 4, so that upon turn-..
ing the nut f the two arms are drawn together, so as to compress the band or clamp tightly around the standard, and also tighten the trunnion, so that it cannot turn in the arms.
' It will thus be seen that by simply tightenposition.
mg up the nut the parts are all clamped tightly together and prevented from moving, and the machine thus secured rigidly imposition. By simply'loosening thenut the trunnion is re leasedand the clamp or band loosened. 'By turning the frame on the trunnion the drill height, and thus it will be seen that there is no position or inclination in which the drill In practice. it will be found that by slightly loosening the out the part-smay he-releztseiL .suflicien'tly to admit of their being readily adjusted, while at the -same time they will'be sustained and prevented from falling.
It is obvious that, instead ofnsing the bolt, the thread maybe cut on the end-of the trunnion, and the nut placed; thereon; that the form of the frame and construction of the drill are immaterial. i
' It is also obvious that, in placeot the nut,
a wedge or eccentric .or other tightening device may he used.
The invention is applicable not only to stonedrilling machines,but to other machines and devices which requiresimilar support and adjustment.
What lclaim as my invention is- Asupport forfrockedrilling machines and similar devices, consisting of a standard, A, a
band, B, encircling the standard, and provided,
witharms a, and a frame, 0, provided with a trunnion. passing through the arms of the clamp, and provided with a nut, f, or equivalent tightening device, substantially as shown and described, whereby tightening the single nut serves to clamp all the parts rigidly in EDWARD S. WINCHESTER. Witnesses: I v C. O. L. DrLnnwnv, W. A. TRIPP. E
