Patented June 19, 1923..
' reales PORTABLE nnrLririve MACHINE.
Application filed Ju1y`2, 1920. Serial NO. 393,761.
(GRANTED UNDER TH PROVISIONS OFTHE ACT OF MARCH 3, 19'21, 41 STAT. 1313.) y
Torall whom t mag/concern.' Y f Be it known that I, HENRI CoLoMBnLLn, a citizen of France, residing at Le Raincy, Seine, France, have invented certain new and useful Improvementsin Portable Drilling Machines (for which applications have been filed in France, March 1.,- 1915 (Patent No. 485,064),- November 28, 1917, and September 12,1919; in Germany7 December 16, 1919; in Switzerland, December 22,- 1919; andin Canada, January 27, y1920), of whichv the fol-lowing is a specification.
The present invention has for its" object a portable drilling ymachine which is easy to work and is so constructed as to be capable of being fixed at any desired point for the purpose ofbeingy used on a particular piece of work. This apparatus ise essentially com-V posed of a frame carryingthe parts of the drilling machine and which.,l under the action of an operating lever, is adapted to be moved along a vertical rod at the bottom 'of which is provided a clamping system with a vertically adjustable clamp jaw whereby the apparatus may be readily fixed at thechosen point in all cases of ordinary practice.
The invention is represented in a constructional form, by way of example, in the accompanying drawing in which:
Figure 1 is a side elevation of the whole apparatus7 the operatinglever being lowered.
Figure 2 is a similar partial elevation, showing the operating lever brought back to its position of rest.
The apparatus comprises a frame a the side lugs b Z) of which are adapted to slide along the rod d. This'frame a carries the drilling machine proper c and the whole can be moved vertically by means of the lever e the part e1 of which forms a cam which bears upon the roller f mounted on the upper part of the apparatus.
The lever c is pivoted in a stirrup g which is xed by a suitable means to the rod cl, at the height required by the work to be done. This means of fixation which must be easy and rapid to operate, will preferably be as follows. The stirrup is provided with a lateral socket which embraces the lrod CZ and which is formed by a fixed part r to which is pivoted by a hinge, a movable part s. These two parts r and s carry lugs t one of which is shown and which can be embraced, once they have-been brought close up; to each other7 by means of a lever e which has a forked .end with inclined sides and mounted` in. such a manner that thenarrow portion of said fork produces an energeticfclampingaction when the lever isl lowered. This lock-ing` dev 'icemay also be replaced by any other which answers the required conditions.
HENRI coLoiviBELLn, on LE RArNcYV, rnance. f
vThe vertical rod CZ is preferably mounted on a horizontal bar or rod by ymeans o which the apparatus can be fixed at vtwo.
points more or less remote from the point where the drilling takes place. For this purpose, the lower end ofthe rody al' is locked., by suitable means in the vertical sleevev by a member having. a vhorizontal sleeve mounted on the horizontal rod y' on'4 which itcan slide but withthe possibility of being Exed thereon at any desired point by means of a suitable locking device. In the example shown, the said sleeve z' is splitand provided with lugs `which receiveclamping screws. y
v Upon the rod j are mounted two members Qone ofl which is shown,7which areada'pted to slide along Vthe said'rod a-ndb'elfixed thereon at any desired point by means of fixing screws Z. Each of those members 7c carries a shaft 701 onwhich rotates the upper jaw m of a clamp the corresponding lower jaw n of which is connected to the 4former by a suitable clamping device. It will thus be understood that the horizontal rod or bar 7' can be rmly fixed and fastened by means ot the clamps which it carries, and can be placed or set in all directions and arranged at any desired distance according to requirements. The machine can be placed on the rod or bar j and xed at any desired point.
Preferably the movable jaw n of each of the clamps can slide along a rack m on which it can be set immediately at a determined point by thethickness of the member to l engages under a catch p acted on by a spring. To release the lever e,- it suiices to push back the said catch p.
The apparatus .thus constructed presents practical advantages in that it can be mounted on the article to be operated on without this latter having to be moved. Once it has been mounted in place, itv affords the same guarantees and the same facultiesl of operation as a fixed drillingmachine.
It must be understood that modifications or variations may be made in practice particularly as regards the arrangements of the `details of the clamps and the locking devices and devices for fixing the different parts.
Having thus described the nature of the said invention'and the bestmeans I know of carrying the same into practical effect, I claim-z y y Y i V1.Y A yportable drilling machine, comprising a supporting rod, a frame mounted to slide and swing upon said rod, colla-rs pro-- vided upon the frame for supporting a' breast drill, a feed lever having a curved endy portion, a` fulcrum mounted to slide and swing upon the rod and in which the vend of` the lever is-mounted, and a roller mounted in the frame in a line with the axis of the ydrill with which the curved portion `of the lever contacts when the lever is swung to feed the drill. t
2. A portable drilling machine, compris-y ing a supporting rod, a frame mount-ed `to slide and swing upon said rod, means provided upon the frame for supporting la breast drill, a feed lever, a fulcrum mounted to slide and swing uponthe rod'and'in which one endyof the lever is, mounted, and
-means on the frame in a line with the axis of the drill with which the lever contacts 'when said lever is swung to feed the drill.
3. A portable drilling machine comprising a supportingv rod, a frame mounte-d to slide and swing upon said rod, means provided uponv the frame for supporting a breast drill in position substantiallyparallel to said rod under all conditions of operation, a fulcrum member'mounted vto slide and swing upon the rod, a. feed lever pivoted at one end in said member, and means on the frame arranged in line with the axis of the drill with whichsaid lever contacts when the lever is swung to feed the drill.
