Specification of Letters Patent.

' Patented Oct. 13, 1914..

. Application filed June 29, 1907. Serial No. 381,403.

To all whom it may concern Be it. known that we. ALBERT BALL and FRANK A. BALL, both citizens of the United States. and residents of Claremont, in the county of Sullivan and State of New Hampshire, have invented an Improvement in Quarrying-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Our invention relates to machines for quarrying or mining use, and while capable of application to other uses and appliances, is herein shown as embodied in a drill carrying quarry bar.

Our invention will be best understood by reference to the following description when taken in connection with the accompanying drawing showing one illustrative embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings :Figu1e 1 shows in rear elevation a truck mounted, adjustable quarry bar embodying one form. of our invention; Fig. 2 shows the same machine in end elevation; Fig. 3 shows the same machine in plan; Fig. 4 is an enlarged plan in section taken through the quarry bar and hanger blocks, with the quarry bar par tially broken away: Fig. 5 shows an enlarged section in plan taken through the hanger block and standard where the former is clamped to the latter, Fig. 6 is a front elevation of one of the two hanger blocks.

Referring to the'drawings and to the embodiment of our invention-which we have there selected for illustration, we have shown a quarry bar 1 adapted to support one or more drilling or other stone working machines 2 (shown only in Fig. 2) in operative relation to the work, which bar is supported upon trucks by means of a skeleton frame work, such that the bar may be raised or lowered to any desired height and there rigidly held while the drill 0r drills are at work, while, on the other hand, the entire machine may be moved about the irregular surface of a quarry with flexibility and ease.

The drill or drills 2, which are shown as rock drills of standard conventional form,

are mounted each upon a saddle 3 of any ordinary or usual construction, of which two are shown in the drawings, although one or any number may be employed according to the number of drills which it is desired to place in simultaneous operation.

In order that the drills may be adjusted to cut in any desired plane or at any desired angle, and also for the object of independently adjusting the drills so that, if not alined orfsupported in just the same way, they may be accurately adjusted to work in the same plane, each saddle '3 is preferably mounted upon a quill or sleeve 1, about which it may be adjustably clampedby means of the clamping bolts 5 at any selected angle. The drill may he therefore worked in a horizontal plane or vertical plane or at any other intermediate angle.

Each quill or sleeve is mounted to fitand slide along the quarry bar, the latter being provided at one side with a spline 6 and at the opposite side with a toothed rack 7, by means of which parts the quills are prevented from turning.

Each quill with its attached drilling machine may Be moved or adjusted lengthwise the bar by means of the pinion 8 meshing .with the rack 7 and secured to an upright shaft 9 journaled in the quill, to either squared end of which shaft a crank handle may be applied to turn the pinion and longitudinally adjust the drill.

The quarry bar is supported at one end by the hanger block 10 and at the opposite end by the hanger block 11, each provided with removable caps, said blocks, during the operation of the machine, being each rigidly clamped tothe face of an end standard 12. Each standard is provided with the base portion 13, having at opposite ends the trucks 14, upon which the entire machine may be wheeled along the quarry bottom.

The body of the standard is of box-like cross-section (seen in Figs. 4 and 5) having a flat front face provided with a slot in which the clamping bolt 15 is adapted to work, the head of the bolt engaging the inner walls of the standard portion and the outer threaded end of the bolt being engaged by a clampin nut 16 resting on the spacing spool or was or 17, the latter engaging the body of the block. By means of the clamping nut 16 either block may be clamped length the clamping y the block 10 is ,ing or lowering of the bar,

rigidly to the standard or loosened thereon, so that it may b1 raised or lowered. The slot in the face of the standard is of sufiicient to permit the necessary range of vertical adjustment of the quarry bar and is provided at its upper and lower ends with an enlargement throu h which the head of the bolt 15 may be wit drawn.

Each block at its upper end is attached to the end of a suspension chain 18 which passes up and over a guiding wheel 19 journaled near the top of the standard and thence down to and about the winding drum 20 journaled between frame pieces 21, the latter bolted one at either side of the standard. The chain may be wound about or unwound from the winding drum by means of a hand crank (not shown) which may be applied to the squared end of a shaft 22, the latter connected with a pinion 23 meshing with a gear 24 fixed to the chain winding drum 20. A pivoted pawl 25 engaging the teeth of the gear 24. may be employed as shown to hold the bar against descent during and after the winding in of the chain. After the bar has been raised or lowered to the selected position, the bolts 15 are tightened and the hanger blocks clamped rigidly in position.

Inorder to make the machine as light as ossible, while, at the same time, permitting it to be wheeled over the rough, irregular surface of the quarry without injuriously wrenching the various parts of which it is composed, he latter are preferably constructed with a view to allowing considerable flexibility in the position assumed during transportation and until the drills are started in operation, when the parts may be clamped rigidly in the position which they naturally assume in the selected position of the machine.

During the working of the drills, the ends of the quarry bar are rigidly clamped within the clamping blocks 10 by means of the clamping bolts 26, but during transportation bolts for the block 10 are unloosened so that the smooth end of the bar may turn within the said block if needs be; the key way and rack, however, being preferably extended through the opposite block 11 to prevent the turnin of the bar therein. Endwise movement of 5m bar relatively to prevented by means of the enlarged cap or collar 27.

Where the clamping bolts 15 pass through the hanger blocks, the latter are preferably provided with a somewhat elongated "slot 28 shown in dotted lines in Fig. 1, in plan in Fig. 5 and in front elevation in Fig. 6, which latter shows the detail of the block with the bolts and other parts removed. During the one place to another as well as in the raisthe clamping wheeling .of the machine frombolts 15 are preferably loosened, so that if the machine settles down at one corner and the standards therefore become thrown out of line, not only can the bar turn in the block 10 to adapt itself to this condition, but each block can swing sidewise or move up or down within a certain limited range. This provides a very flexible frame support, which can readily be transported over very rough surfaces without straining the connecting parts. On the other hand, when the selected position is reached, the clamping bolts may be set up and the bar held rigidly by its supports, which latter, however, are in the position which they naturally assume with reference to the irregularities of the quarry supporting surface.

In order to tie the standards and their bases together without at the same time decreasing the fiex-ibility of the machine, there are preferably provided the lower distance rods 29, one at each side of the machine, said rods being preferably provided with adjustable devices, such as the turn buckles 30. The distance rods 29 are provided at their ends with eyes which engage the projecting upper ends of hubs 45, the latter be ing secured to the base piece. In order to hold the machine steady while the drills are working, there is preferably provided some means in addition to the trucks. Such means may consist of suitable clamping devices or the like, but herein the pins 31 pass through the standard and are provided with preferably hardened ends 32 adapted to engage the surface of the rock. \Vhen the machine is positioned, these pins may be driven down into the rock and fastened by set screws 33.

At the top of the machine there is also preferably provided a distance rod or member 34 extending from one standard to the other, the upper distance member serving to maintain. the proper distance between the standards when the bar is lowered and the lower distance members 29'serving the same object when the bar is up and when the machine is moved abo it the quarry.

When the bar is loosened from the standards for raising or lowering, it is desirable to provide some additional support other than the steel pins 31 to kee the standards in position, and we have therefore shown each standard provided with a lateral brace rod 35 hinged to a pair of ears 36, each brace being preferably made up of a length of tubing provided with a clamping collar 37 and an extensible point 38. When not needed the Points 38 may be telescoped' within the tubing portion of the brace and the latter swung up and fastened to the side of the standard by means of the locking device 39. When the machine is positioned and it is desired to adjust the bar, the braces may be swung out steel or other hardened and the F ig, 1

In order to brace the topof the'machine against the reaction ofthe drill, any suitable means may be employed, such, for example, as the anchorwedge 40, which is adapted to be driveninto a cut in the block which is to bedrilled. This. wedge is connected by means of the strap or clevis 41 with the stay rod 49-. the latter passing through tlleSW-lVGlBdfilRIIlPlII block 43 in the top of the standard, towvd ich blockit may be fixedly secured by the set screw. 44*. An. anchor Wedge ispreferably employed for each standard as shown, although a single anchoring device only may. be used.

While we have shown! one embodiment of our invention and described the same in detail for thepurposes of. illustration, it is to'be understood that our. invention. broadly may be applied to other forms of. machines than the specific one herein shown and independently of andapart from the disclosed details of construction and form and relative points extended as represented. in

arrangement of parts, whichit is to be under- I stood may be Widely deviated from Without departing from the spirit of the invention.-
