Patented July 19, 1938 UNITED STATES PATENT OFFICE DRILL PULLER 4 Claims.

This invention relates to improvements in drill pullers and more particularly a device to be used for removing drills from rock and earth which have become frozen against dislodgment.

The primary object of this invention is to provide a drill puller of the above mentioned character including an upright post to which is pivoted a fulcrum, bar carrying a pair of drill gripping dogs capable of effecting a vertical straight line pull on the drill.

A further object of this invention is to provide a drill puller of the above mentioned character having means for exerting force in an upward direction to the fulcrum bar whereby said means may exert more power thereto due to the fact that it is supported on the ground or earth from whence the drill is being removed.

A still further object of this invention is to provide a handle to be used in conjunction with the above mentioned means in order that the fulcrum bar may be oscillated after the drill has been loosened from its frozen position.

Other objects and advantages of the invention will become apparent during the course of the following description taken with the drawing, wherein Figure 1 is a side elevational View of the device embodying this invention, showing a portion broken away to illustrate the location of the drill gripping dogs;

Figure 2 is a plan view of the same and shows the manner in which the drill gripping dogs are carried by a pivotal plate carried by the fulcrurn bar, and

on lines 3-3 of Figure 1 looking in the direction of the arrows and illustrating the manner in which the fulcrum bar is pivotally connected to the upper forked end of the supporting post.

In the drawing, wherein for the purpose of illustrating the invention and wherein like reference characters will be employed to designate like parts throughout the same, the reference character 5 will generally be employed to designate a fulcrum bar supporting post having the lower end flared outwardly as at 6 and terminating in a flanged portion 1 capable of resting on the plank 8 supported on the ground or earth 9 in proximity to a drill D, the removal of which is desired.

The upper end of the supporting post 5 is forked as at I0 for receiving a fulcrurn bar II held in place b-y a fulcrum pin I2. One end of the fulcrum pin I2 is threaded for receiving a nut I3 and a lock washer I4 is interposed between the Figure 3 is a vertical cross-sectional view taken I nut I3 and forked member IU. A boss I5 is formed on the fulcrum lever I I to properly space the same between the forked end I0 of the supporting post 5 and the boss is arranged in such a manner as to allow the pivot pin I2 to extend 5- through the central opening I5 formed therein.

Journaled on the fulcrum lever II is a dog- `carrying plate I1 havingA an opening I8 formed intermediate its ends for receiving a pivot pin I9 extending through a central opening 28 formed in a boss 2l on the fulcrum lever II. Bracing ribs 22 are disposed on the fulcrum lever II and extend longitudinally thereof on opposite sides of the boss 2l) so that their inner ends terminate in the boss. One end of the pivot pin I9 is provided with a head 23 which is received in a recess 24 communicating with the opening I8. The opiposite end of the pin I9 is threaded as at 25 for receiving a locking nut 26.

Secured to the ends of the dog-carrying plate I1 are pins 21 and 28 adapted to carry a pair of dogs 29 having drill engaging teeth 30 presented to the drill D at an angle to cause the drill to be locked in place and the teeth grip of the drill to prevent slippage. The dog-carrying pins 21 and 28 are provided with bosses 3| to prevent displacement of the dogs 29 against lateral movement.

It willbe noted that the pin 28 is extended a short distance for receiving a strain plate 32 having an opening 33 at one end and an opening 34 at the opposite end. The pin 28 is received in the opening 33 While the opposite end of the plate has its opening 34 passed over the screwthreaded portion 35 forming an extension of the pin 21. A nut 36 may be threaded on the screw-threaded extension 35 to allow removal of the strain plate 32 when the device is being positioned for operation upon a frozen drill D.

The `free end of the fulcrum lever I I is provided with an oli-set portion 31 having an extension 38 for accommodating means for exerting an upward force such as a screw jack or the like. The extension 38 is centrally drilled as at 39 for receiving a handle 4D whereby a series of vertical movements may be accomplished after the frozen drill D has been loosened.

In the present instance a screw jack 4I is employed for -exerting a force in the direction of the arrows upon the free end of the fulcrum lever and said screw jack comprises a base 42 fastened or otherwise secured to an elongated plate 43. In order to prevent the elongated plate 43 from being pressed into the ground when the device is in operation, a plank or board 44 having a large surface area is mounted beneath the elongated plate 43. A rotary screw-threaded bar 45 is rotatably mounted in the screw jack 4i and is adapted to be rotated by means of bevel gears 46 manually operable by means of a crank 41. Formed on the upper end of the screw-threaded bar 45 is a swivel coupling comprising parts 4S and 49 between which is mounted ball bearings 50 to allow free rotation of the screw-threaded bar 45 relative to the part 48. A lug 5| is formed on the section 48 of the swivel connection and extends between a pair of depending lugs 52 formed on the extension 38. A pin 53 or other fastening means may be provided for coupling the lug 5l to the depending lugs 52.

The jack structure is normally separate from the extension 38 of the fulcrum bar H, but is readily attached thereto by means of the pin 53 inserted in the lugs 5I and 52. When the jack is separated from the fulcrum bar, the extension end 38 moves downwardly, the fulcrum bar being prevented from complete collapse by reception in the notch Illa in one side of the fork I for support in an inclined position as will be evident from an inspection of Figure 1. The fulcrum bar is then prevented from moving laterally with respect to the post so that injury to the bearing boss l5 will be eliminated.

It will be understood that the drill rod D will not be bent or twisted during its removal from the bore hole in view of the fact that the dogs 29 will maintain a parallel relationship irrespective of the movement of the fulcrum lever I'l and that the strain plate 32 will prevent undue stresses upon the dog-carrying pins 21 and 28.

It will also be understood that the device shown in the drawing is to be taken as the preferred embodiment of the invention but obviously changes in the shape, Size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-joined claims.

I claim:

1. A drill puller of the character described, comprising a support, a lever having one end fulcrumed to the upper end of the support, means carried by the free end of the lever for exerting a vertical force thereto, a dog-carrying plate pivoted intermediate the ends of the lever, and a pair of dogs pivotally attached to the ends of the dog-carrying plate for engaging a drill.

2.
