6 Claims.
The present invention is directed to an impact producing implement and more particularly is concerned with a functionally and structurally improved serviceable lock pick gun and the objects, advantages, and features thereof will be apparent from the teachings of the following detailed description viewed in the light of the accompanying drawing wherein:
Fig. 1 is a perspective view of the lock pick gun according to my invention.
Fig. 2 is a front elevational View of Fig. l with parts broken away to show the internal construction.
Fig. 3 is a View similar to Fig. 2 howeverA illustrating the impact delivering rocking arm in a released position and ready to impart a blow to the vertically shiftabie lock pick shoe or holder.
Fig. 4 is a sectional View on the line 4 4 of Fig. 2.

Fig. 6 is a sectional View taken on the line 6--6 of Fig. 3.
Fig. 7 is a sectional view on the line 'I-I of Fig. 3, and
Fig. 8 is a perspective view of a modified form of shoe and support.
Illustrative of the embodiment disclosed, the lock pin gun is generally denoted Ill and comprises a hollow metal casing I I, a pivoted trigger I2, a trigger locking pawl or dog I3 pivotaily mounted on the pivoted impact delivering rocking armor hammer Iii, a vertically and bodily shiftable lock pick holder or shoe I5 and the lock w pick I6.
According to the invention shoe i5, is vertically guided between upper and lower stops II and I8 integral with the back wall I9 of the casing by a key or rib 2@ projecting from wall I9. More particularly rib 2S cooperates with the spaced transverse walls of the vertical keyway or slot 2| in the shoe to vertically and slidably guide the shoe between the baci: wall or plate I3 and the cover 22 of the case.
The shoe or pick holder I5 is provided with upper and lower anges 23 dening a channel in which the expanded part 24 of the pick is inserted and clamping means in the form of a bolt 25 and nut Z5 is utilized to hold the expanded part 2li firmly against the reduced part 2l ofthe shoe which overhangs the forward end of the casing. In the normal or retracted position of the trigger (Fig. 1) the shoe I5 is also in a retracted or elevated position, namely, the upper flange 23 together with the upper face of the shoe are against the upper stop Il which serves as the top wall of the casing.
In such retracted relation of the shoe, it will be' observed lower flange 23 is spaced or away from the lower stop or seat I8 and cap or tumbler 28 which is telescopically slidable in bore 29 of the rear part of shoe I5 and which is now against the stop I'I compresses the helicoidal spring 34)A in that the hammer portion 3l of the impact delivering device I4 is in its fully raised position and abutting the lower flange 23 of the shoe, thus supporting the latter.
The impact delivering device I6 includes the transversely arranged bore 32 receiving the fixed fulcrum post 33 which extends from the rear wall of the casing. By this arrangement the impact delivering device is pivotally or rotatably mounted on the fulcrum post 33. The impact delivering device also includes a recess 3 which is bridged by the fixed fulcrum post 35 secured to sides 3S- of recess 313, which sides serve to tiltably guide pawl I3 pivotally sustained by post 35.
The latch or pawl I3 has its longest arm :il normally urged outwardly by reason of the helicoidal spring 38 in part encompassing a, post 39 fixed to arm 3l and in part projecting into a recess lll) in the impact delivering device or rotatable lever I i which is provided with a bore I housing the normally expanded spring 52 surrounding the reduced stem of the slidable tumbler 43 telescopically receivable in bore M.
For controlling the power of the impact to be struck by hammer portion 3l of the impact delivery device Ill against shoe E5 means has been provided for adjusting the power spring 42. To this end a threaded set screw ill is employed. This set screw is threadabiy connected to stop II and to a depending lug integral with the stop and cooperates with the slidable tumbler 43 to regulate the desired kick back power in the spring 52.
As previously set forth the trigger I2 is normally in a retracted position as shown in Fig. 2. This trigger has one arm d5 pivoted on the xed fulcrum post t xedly carried by the rear wall of the casing. Another arm t6 of the trigger is provided with a nose or lip portion il having an inclined actuating shoulder or projecting catch G8 disposed in close proximity to end face 59 of the long arm 3l of pivoted pawl I 5. As shown in Fig. 2 the forward end of trigger I2, which is normally held in a retracted position by reason of reach 523 of the inverted U shaped leaf spring 5I appropriately retained within the casing, is interlocked with the forward end of the pawl, that is, end face 43 of `the pawl cooperates with shoulder 48 of the trigger to lock the latter against involuntary rearward displacement. If therefore the nger gripping portion El of the trigger is moved rearwardly, the trigger is caused to pivot rearwardly against the resistance of reach 5G.
During this operation shoulder :3 abuts the end face 4S of the pawl, thus bodily shifting the latter rearwardly and since the tapered tail or short arm 52 of the pawl is against the inclined face 53 of the rockable hammer or impact delivering device I4 the latter is pivoted bodily or counter-clockwise. Thus the hammer portion 3| of the hammer or the impact delivering device I4 is moved away from the shoe I5 and the latter drops by gravity on the lower stop I8 and such action is accelerated by the expansion of spring once the shoe I5 loses the support of the hammer. To resist tilting of the shoe I5 after the support of the hammer I4 has been removed, the rear end of the shoe has a projection 54 cooperating with the curved stop or seat to limit downward displacement, that is, the shoe drops vertically at the beginning of an operative cycle which starts to take place at the beginning of the rearward stroke of the trigger thus causing the upper flange 23 of the shoe to fall away from stop I1. As the cycle continues the trigger continues to travel rearwardly, lip 43 continues to abut the latch which in turn causes the impact producing device to rotate or pivot rearwardly, that is, counter-clockwise at which time the helicoidal power spring 42 becomes compressed in that the shank of the set screw 44 forces the slidable tumbler into bore 4I The impact producing device or hammer I4 rotates rearwardly until lip 41 of the trigger slips off from the end face LltI of the nose of the long arm 31 of the pawl I3. Thus the trigger becomes free of the pawl in which instant the power spring lower flange 23 of the shoe I5 which is abruptly lifted or raised from its stops or seats I8 and 55 and against the energy spring 30 to abruptly position the upper iiange 23 of the shoe against the stop I1. In other words, a sudden blow is imparted by the hammer portion to the shoe and consequently the pick thereof is also bodily lifted.
With the impact producing device I4 automatically restored to its normal position (Fig. 2), the trigger is also retracted automatically upon release of nger pressure on the manipulating portion 5I in which instant reach 50 of the leaf spring 5I urges the trigger forwardly. On the retraction of the trigger cam face 56 of the lip 41 contacts the bottom curved face 51 of the pivoted pawl I3 thus causing the long arm 31 of the latter to be rocked into the recess 34 against the action of spring 38 to permit lip 41 of the trigger to pass the nose or front end of the pawl after which spring 38 expands causing the arm 31 of the pawl to move outwardly again and interlock with lip 41, thus ending a complete cycle of operation and the trigger is again in its normal and waiting relation.
It follows therefore that on each cycle of operation, the lock pick drops against the lower stop as the trigger starts to recede, the hammer begins to pivot rearwardly, the power spring starts to store a certain amount of energy until the pawl becomes free of the lip of the trigger at which time the power spring suddenly dissipates its energy and the hammer automatically retract-s to strike the shoe carrying the lock pick. Therefore the latter is elevated against the upper stop. Following this impact to the trigger retracts automatically to interlock with the pawl. Thus by the present arrangement a certain vibratory motion is imparted to the pick when the trigger is snapped through several cycles. The lifting impact to the pick is utilized to control certain tumblers of a conventional cylinder lock (not shown) that is, in the matter of picking the latter. The lifting impact applied to the tumblers is transmitted to the drivers of the cylinder lock for parting the latter from the tumblers. Once this is established the cylinder lock is picked. This is in line with the well known principles of picking cylinder locks and further discussion in respect to the method of picking locks therefore need not be further discussed.
The shoe I5' according to the showing of Fig. 8 is provided with bore 62 for receiving the rear end of the pick I5 which is adjustably held clamped by the set screw 6 I Attached to the bottom face of the shoe I5 is the block 50 which is of a suitable sound deadening material. This block is provided with an arcuate shoulder 55 cooperating with the curved stop 55 to prevent tilting of the shoe when hammer portion 3| of the rockable lever I4 is operated. In other structural aspects the form according to Fig. 8 is along the lines of the embodiment according to Fig. 1.
Without further analysis, the foregoing disclosure will so fully reveal the gist of the present invention that others may by applying current knowledge readily adapt it to various applications without omitting certain features, that from the standpoint of the prior art, fairly constitute the essential characteristics of the generic and specific aspects of the invention and therefore such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.
