REAMER-GU-IDE MECHANISM.
SPECIFICATION forming part of Letters Patent No. 434,035, dated August 12, 1890.
Application filed December 2, 1889. Serial No. 332,280. (No model.)
To all whom it may concern:
Be it known that we, \VADE J. W'ARNER, of North Amherst, Lorain county, Ohio, and ISAAC GRACE, of Berea, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Reamer- Guide Mechanism; and we do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
Our invention relates to improvements in reamenguide mechanism used in quarrying stone; and it consists in certain features of construction and in combination of parts hereinafter describechand pointed out in the claims.
In quarrying stone it is customary to drill a row of holes in line, and a so-called reamer is employed to cut V-shaped grooves on opposite sides of these holes to give direction to the line of fracture in blasting the rock. If the reamer is not held with considerable accuracy, the V-shaped grooves are not cut in line with the row of holes, and consequently the fracture of the rock will not run in a To avoid such diiiiculty and to save the expense of a man for holding the reamer, we have devised the improved apparatus illustrated in the accompanying drawings.
Figure 1 is a front side elevation partly in section. Fig. 2 is a plan. Fig. 3 is a detail of slotted tube F detached. Fig. 4' is a bottom plan of the reamer. Fig. 5 is a view of the upright arms detached. A represents a metal yoke mounted on three legs a a a, these legs being pivoted to the yoke so as to swing in planes toward and from the center of the apparatus in the manner of a tripod, by means of which the apparatus may be raised, lowered, or leveled. The lower extremes of the legs should be pointed, as shown, so as not to slip on the rock floor. To the inner face of the yoke are attached two upright arms B B, opposing each other, these arms being preferably dovetailed to the yoke, as shown in Fig. 2, the securing-bolts 1) extending through holes in the yoke and through slots 1) of the arms, with which construction by loosening these bolts arms B B may be raised or lowered a few inches, as may be required. The inner faces of these arms are provided with grooves B, in which operates the end section of cross-head C for guiding the latter. The lower ends of arms B are slotted, as-shown at B for receiving the end sections of cross-barD. The latter has shoulders at d for engaging the inner faces of arms ]3, and the cross-bar is provided with studs D, nuts D, and washers D arranged substantially as shown, and by tightening these nuts the cross-bar and arms are clamped firmly together. By loosening these nuts, the cross-bar may be moved up or down the length of slot B say, four or five inches, more or less.
E is the so-called reamer, substantially as heretofore used for the purpose, a bottom plan of which is shown in Fig. 4. -The reamer is usually about an inch broader than the diameter of the drilled hole in the rock, so that it will cut a V-shaped groove about a half an inch deep on either side of the drilled hole. The shank E of the reamer is square or rectangular in section. Cross-bar D has a slot D midway thereof, in which slot the shanks of the reamer may operate loosely; also, the
cross-bar is provided with holes D D opposite the center of the slot for purposes hereinafter mentioned. Cross-head O has a slot 0, preferably curved, as shown, and in this slot operates a bolt 0, the forward end 0' thereof being adapted to hook around shank F. to clamp the latter to the cross-head, this bolt being provided on the rear side of the cross-head with washer and nut, as shown at 0 F is a tube adapted to fit in the drilled hole of the rock, and this tube is closed at the bottom and has slots F on opposite sides of the tube, these slots extending from the top to the bottom walls of the tube. These slots are adapted to accommodate lips e of the reamer, the central or body portion of the reamer resting loosely inside the tubes. To
inserted in the hole in the rock in position with slots F in line with the desired fracture of the rock, usually in line with the row of holes. Next, the apparatus is set over the hole and the rounded ends of straps fare entered into holes D the cross-head D being raised or lowered for the purpose, as may be necessary. The legs are adjusted to bring the axis of the machine in line with the hole, the shank of the reamer E meantime having been passed up through slot D from the bottom. The reamer is-next inserted in tube F, the wings of the reamer of course protruding through the slots of the tube. Cross-bar O is raised to near the top of the guide, and shank E, by means of bolt 0, is rigidly clamped to the cross-head. The operator, by means of a sledge, drives the reamer down until the head thereof strikes the-end wall of tube F, or, rather, until the reamer strikes the cuttings accumulated in the bottom of the tube. It is evident that the cuttings of the reamer will all fall into the tube, and when the reamer is driven as far as it will go the reamer by engaging the cuttings packs the latter so firmly in the tube that the cuttings are all removed with the tube, when the latter is afterward drawn out of the hole, and henceis saved the labor of spooning out the hole. The weight of the cross head clamped to the reamer materially aids in driving down the reamer, so that one workman, by the aid of our improved apparatus, can do more work than could be done by two men operating with the old method. After the reamer has been driven home, cross-head O is drawn up to extract the reamer, and the apparatus is lifted and set aside. Next, tube F is removed from the hole, and the cuttings discharged from the tube, and this completes the operation.
The apparatus is not so heavy but that two men can readily lift and carry it from one hole to another, and as there are usually a large number of men employed at a stonequarry it is not necessary to keep an extra man to help remove the apparatus.
Vhat we claim is 1. In stone-quarrying apparatus, the combination, with the reamer, substantially as indicatel, of a'frame having upright ways, and a reciprocating cross-head adapted to be clamped to the reamer-shank, and a cross-bar adjustably secured to the ways at or near the lower ends of the latter, such cross-bar having 5 5 a slot adapted to receive the reamer-shank loosely, substantially as set forth.
2. In stone-quarrying apparatus, the co n-f, bination, with the reamer, a frame havlng" upright ways, a cross-head operating on such ways, such cross-head being adapted to be clamped to the reamer-shank, and a crossbar adjustably secured to such Ways, such cross-bar having a slot through which the reamer-shank operates, of a slotted tube operatively connected with such cross-bar, such tube being adapted to fit the hole in the rock for blasting and adapted to receive the body or central portion of the reamer, with the lips thereof protruding through such.slot, substantially as set forth.
3. In stone-quarrying apparatus, the combination, with the reamer and guiding mechanism, substantially aSiHCIiCZLiJMLOf a slotted tube having a closed lower end, such slotted tube being detachably connected with the guiding apparatus, such tube being adapted to fit the hole in the rock and adapted to receive the body of the reamer, with the lips of the reamer protruding through the slots of the tube, substantially as set forth.
In testimony whereof we sign this specification, in the-presence of two witnesses, this 20th day of November, 1889.
