Patented July 19, 1932 UNITED STATES PATENT orrics EDWARD F. TERRY, JR., OF DENVER, COLORADO, ASSIGNOR TO GARDNER-DENVER COM- IPANY, OF DENVER, COLORADO, A CORPORATION OF DELAWARE noon DRILL SUPPORT Application filed March 28, 1929 Serial No. 350,691.
The object of the present invention is to provide a novel combination whereby the feeding means for a rock drill constitutes a part oi the self-sustaining support for the drill during drilling operations.
The preferred embodiment of the invention is illustrated in the accompanying drawings, .wherein Figure 1 is a rear elevation of the struc- IQ ture,
Figure 2 is a longitudinal sectional view on the line 2-2 of Figure 1 and with one of the supporting legs shown in section.
In the embodiment disclosed, the drill per 51 se consists, as usual, of a drilling motor 3, adapted to operate on a tool or steel 4. This structure is well known in the art, and it is believed needs no specific description. As shown it is of the pneumatic hammer type.
For the purpose of feeding the drill 3l to its work, an extensible feed leg is employed, which in the present structure comprises a lower cylinder member and an upper piston member. The lower member comprises a cylinder 5 having a lower head 6 provided with a spur 7 adapted to engage the ground or other supporting surface. Suitable means are employed for introducing air or other motive fluid to and exhausting it 30 from the cylinder, this means being controlled by avalve indicated at 8. Fixed to the upper end of the cylinder 5 is a guide shell. or cradle 9 having guideways 10. In the bottom of the said shell or cradle is fixed a longitudinally disposed rack 11. The drilling motor 3 is slidable in the guideways' 10 and has a longitudinally disposed rack 12 located in opposition to the rack 11.
The piston member comprises a piston ead 13 that reciprocates in the cylinder 5 under the influence of the'motive fluid admitted thereto. This head carries a piston rod 14 that projects beyond the cylinder into the cradle or shell 9 and carries a pinion 15 in mesh with the racks 11 and 12. Obviously therefore when the piston is moved upwardly. the drilling motor will be moved upwardly and as the drilling of the hole progresses the motor will be fed to itswork.
The under side of the upper end portion of the cradle or shell 9 is provided with a transversely disposed ear 16 through which eX- tends a bolt 17. This bolt constitutes the pivotal mounting of brackets 18 that are journaled on its projecting ends. The brackets 18 have depending ears 19 and to these ears are pivoted by bolts 20, the upper ends of the tubular sections 21 of extensible legs. These legs in addition have rod sections 22 slidable in the tubular sections 21 and adapted to be held at any desired position by collars 23 secured to the rod sections and abutting the tubular sections 21. 'Set screws 24; serve to secure the collars in any desired position on the rod sections.
With this structure, it will be noted that the cylinder member of the feed leg constitutes part of a tripod, of which the legs 21-22 form the other members, and that therefore these members can be set up to provide an upstanding self-sustaining support for the drill. The drill can be set at different inclinations and by extending the legs as desired the support can be placed on rough and uneven surfaces.
From the foregoing it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
What I claim, is:
1. In a rock drill, the combination with a stationary teed cylinder having a spur on its lower end and a longitudinally disposed guide shell on its upper end, of a drilling motor slidable in the guide shell, a movable piston in the feed cylinder having connections with the drilling motor to slide it in the shell, and legs for supporting the cylinder and guide shell in an upstanding position, said legs being connected to the shell.
2. In a rock drill, the combination with a stationary feed cylinder having a spur on its lower end and a longitudinally disposed guide shell on its upper end, of a drilling motor slidable in the guide shell, a movable piston in the feed cylinder having connections With the drilling motor to slide it in the shell, a bracket pivoted on a transverse axis to'the underside of the shell, and legs ivoted to the bracket to swing transversely of the'shell and constituting means for Sup! porting the cylinder and guide shell in an upstanding position. v i 3. In a rock drill, the combination Wit-ha stationary feed cylinder having a; spuron its lower end-and a longitudinally disposed guide shell on its upper end, of a drilling motor slidable in the guide shell, a movable piston in the feed cylinder having connections With the drilling motor to slide it in the shell,i2t bracket pivoted on a transverse axis to theunderside of the shell, and extensible legs pivoted to'the bracket to swing w transversely of the shell and constituting means for supporting the cylinder and guide shell in an upstanding position.
o In testimony whereof, I affix my signature.
EDWARD F.v TERRY, JR.
