UNITED STATES PATENT OFFICE.
DANIEL J. CHICKERING, OF SPOKANE, )V'ASHIITG'ION, ASSIG-NOR OE FIFTY-ONE PER GENT TO EGGERS POLE & SUPPLY COMPANY, OF PARKWA'IER, WASHINGTON.
PORTABLE PUNCHING MACHINE.
Application filed April 2, 1925.
.10 all whom it may concern:
ING, a citizen of the United States, residing at Spokane, in Spokane County and State of lVashington, have invented certain new and useful Improvements in Portable Punching Machines, of which the folloi'ving is a specification.
My present invention relates to improvements in portable punching machines especially adapted for the purpose of punching holes in the surface of logs or poles, as telephone or telegraph poles preparatory to impregnating the wood of the pole with a preservative, such as carbolineum, which is applied as by dipping the punched pole into a vat or container for the preservative.
The machine is motor operated and manually controlled and manipulated and utilizes a gang of reciprocating tools for punching the surface of the pole. The machine is self-contained and its operating parts which are few in number are compactly arranged for speed in their movements and for quickly and satisfactorily puncturing or punching the pole.
In use the machine is placed upon the top of a horizontally disposed and properly supported pole or other object to be punched, and the machine, by manual power is shifted longitudinally of the pole, preferably stepbystep, from one end of the area to be punctured or punched to the other end and then returned. As the machine is moved forward and back the pole is turned on its longitudinal axis while the machine is main-V tained in upright position in order that the entire area to be punched may be filled with holes in desired number. A gang of punches are actuated by power from a motor as the machine is manipulated, said punches being mechanically lifted against the tension of springs, and by these springs forced downwardly to penetrate the wood on their working strokes.
In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged for the practical application of the. principles of my invention. i I
Figure 1 is a view in side elevation of a mach e n edr s y i n ive;
Serial No. 20,146.
Figure 2 is a top plan view of the machine of Figure 1.
Figure 3 is an enlarged detail elevation partly in transverse section showing the punch or tool frame and the gang of punches.
Figure 4.- is an enlarged vertical sectional view showing the cam actuating means for a punch.
The machine is mounted upon a main frame or carriage 1 of generally rectangular shape, and, with its parts compactly arranged for supporting the, operating parts of the mechanism. The transversely disposed axles 2 and 3 are provided for the carriage and provided with concave rollers l and 5 shaped to conformto the exterior surface of the pole P overwhich the rollers are designated to travel longitudinally of the pole. The machine is designed to be propelled manually along the pole backward and forward over the area to be punched, preferably with a step bystep movement, or an intermittent movementregulated according to the movement of the gang of punches.
Power for the operating mechanismcau ried by the main frame or carriage is supplied from an electric motor 6 which is lo cated at what may be termed the front end of the machine and by its weightadds to the stability of the machine. 7
The punching mechanism comprises two alternating sets of tools which are mechanically lifted or elevated and caused to' move on their downward strokes by spring pressure applied thereto. For elevating the tools or punches a cam mechanism is employed and operated from the motor 6 through a small pinion 7 on the motor shaft 8. A larger gear wheel 9 with its shaft 10 journaled in the main frame and also in a housing 11 at the side of the main frame receives power from the pinion, and the shaft 10 has thereon a smaller gear 12 which meshes with a driven gear wheel 13 on the cam shaft 14. The cam shaft is journaled in the main frame andextends transversely of the carriage or frame in position between the frontandrear rollers of-the carriage.
- --Upon the cam shaft 'are keyed -a series of cams or cam disks 15having spac ng collars 16 between ad oin1ng cams and these cams "9 m-di k ateeaa s l s e Sets ax alternately lift their respective sets of spring pressed punching :tools through the instrumentality of a series of levers also perating in two sets.
These lifting levers-17 are of identicalconstruction and are pivoted on the lever bar 18 arranged parallel with the cam shaft and supported in the upper part of-the main frame or carriage back of the cam shaft.
Each lever has a lug 119 on its under edge to ride upon the peripheral edge of one of the cam disks, as seen in Figure 4:, and at its free end the lever has a lifting lug 20 for co-action with the punching tool.
The punching tools are arranged in a series extending transversely of the machine and reciprocating in twoalternate sets. As seen in Figures 3 and at the tool preferably has a shairk 21 square in or ss section and a laterally projecting head 22, the latter for coaction with the lifting lug 2001i the free end of the cam lever. At its lower end the shank hasa socket 523 for apointedpunc'lr i'ng tool 24 which is d'etaehably secured in the socket by suitable i neans.
The punching tools are carried in the tool frame 25 located transversely-of the main frame and supportecbas by bolts therein. Asseenin "Figures and f the punch frame or tool fraime is provided with a plurality of sockets 2 6- "T-hich are arranged on angular lines which converge toward the longitudinal axis of the pole P in Figure 3 and the two sets of punches are located in these sockets and adapted to reciprocate thereini In the upper ends of the sockets are located tens n springs 27 *which are compressed and interposed between the top ends of the shanks 21 and screw ping-s; oi closures 28 for the sockets, and it willbe apparent that the springs are designedto urge or force the respective tools dew-n wardly on their working strokes toward the pole.
. co 'action of s. his the nan icated in dot ed ring is EQGIllPTBEh e s'pr and lever lift-the lines" in --i -igu'-r e t me handles 30are attached at the respective ed,- end a he sinus 1.4? 9f he are e dies verse movement on the pole. The operation of the two sets of tools is accomplished'in unison and on alternati'n strokes to reduce undue vibration of the inachine'and this alternate movement may readily be provided for by adjusting th'etwosets of the cams with relation to one another. After the carriage has traveled the required distance in one direction on the pole it is stopped and then propelled in the reverse direction with the tools in operation. The pole or other work being punched is turned at the .proper intervals in suitable manner, and the work, progresses until the desired result is accomplished.
Having thus fully described my invention-What I claim as new and desire to se-' cure by Letters Patent is- 1. The combination in a portable punching machine with a carriage, of a punch frame supported in the carriage and a series of 'reeiprocable punches in said frame, an
7 operating shaft and :1 motor 'on'the frame, I power transmission mechanism between said motor and shaft for lifting said punches, andmeans for automatically operating said punches on their down-Ward working stroke.
'2. The combination in a portable punching machine with a carriage, of a punch frame sup'ported in the carriage, agang of reciprocable punches supported in said frame and arranged in sets to move in opp'osite'directions, .an operating shaft and a motor and driving connections between said motor and shaft, means actuated by the shaft for positively 'liftingone set of tools and automatic means for causing a down ward Working stroke of the other set of tools wlii l'e rtheot'lier set is being lifted.
3. The combination with a. carriage of a punch frame having a series of sockets, a gang of punches in saidsockelts, a-motoi, an operating shaft and driving connections be tween sa idii'iotor and shaft, means actuated from said shaft for lifting said gang -in alternating-sets, and resilient means for causing downward working stroke of said punches. V y
