Description

ets 45. However, in some instances the supporting frame will be made narrower than shown in the drawings, and in this instance the larger drum or bullwheel 'will extend suiliciently so that ,the cable will clear the frame. I a

To prevent backward rotation of the larger drum or bull-wheel 34 during the operati o'opi hoisting or pulling one of the heads of said druln q Ibull-wheel is termed into a ratchet-wheel 46 withwl ich engages a gravity pawl 47, the latter being'provided with. a removable. handle-bar 48 for moving it out of engagement.

The mast is braced by means of'inclined brace-bars 50, which are attached at their lower ends to the sup-' porting frame and at their upper ends are secured to the lower section.5.of said mast.

For the purpose of connecting the machine the supporting irameis provided atoppowheels 52.

stood irom the foregoing description, in connection with the accompanying drawings, for alter the machine has been placed in position and the mast extended to its full height by operating the drum 25, the latter is then connected to the shaft, and alter removing the cord 23 the drum 34 may be turned manually by means of the crank-handle ill, and the'hoisting cable being wound upon the drum ill will pull upon the tube or rod to which the cable is attached. It it is desired to operate 'the drum 34 by horse power. the drum 25 is first disconnccted from the shaft by removing the pin 29, and a rope is wound backward around said drum by turning the crank-handle; then after inserting the pin or key 29 and attaching a horse to the rope thelatter may then b pulled upon to turn the drum 25 and drum 34. in the operation of the drum in pulling upon the cable the pawl '47 is placed in engagement with the ratchet-wheel 46 of the drum so as to prevent backward rotation of said drum. After the rod or tube has beenpulled, and it is desired to lower the same to the ground the pawl 47 is disengaged from the ratchet-wheel 4n, and the brake (i0 is applied so as to gradually lower the tube or rod. -lt will. be seen, therefore, that I'provide a simple, compact and easily operated portable machine for pulling tubes and rods, and which may be readily moved l'roin place to place and quickly set up for work.

Having thus (lescribed'my invention l' tlo noi. wish. to t be limited in my patent protection tothe precise construction and arrangements of parts as herein shown and doscri bed, as it is obvious that changes may be made in the construction of the machine without departing from ihe spirit and scope of my claims and without sacrificing any of the advantages of tho machine.
