le all 1who/m. it may concern: Y

Be it known that I, WILLIAM F. GEHRIG, a citizen of the United States, residing at Newark, in the county of Essex and, State of New Jersey, have invented certain Improvements in Repeating Cap-Pistols, of which the following is a specification.

The objects of this invention are to secure a pistol of the repeating type which can be easily and conveniently loaded with a fresh roll of caps; to secure a construction in which this is done by breaking the pisis automatically removed entirely from the cap-strip on its return stroke; topr'ovide means for throwing said feeding finger into positive engagement with the cap-strip again; to enable said means, the feeding iin ger and the hammer, to'be operated by a single spring; to prevent backeiring of the pistol; to secure a simple construction which can be stamped out of sheet-metal, and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several figures, Figure 1 is a side elevation of the pistol with the hammer down and parts in normal position, thenear side-piece being removed; Fig. 2 isa view of the pistol from the reverse side, the near side-piece being removed and the barrel swung up into loading position. Fig. 3 is a view similar to Fig. 1, but showing-the parts in their positions just previous to falling of the hammer when the trigger is pulled; Fig. 4 is ,a similar view immediately after the hammer has fallen and before the trigger has returned to normal position; Fig. 5 is asimilar view with the trigger almost back to normal position, and the feeding nger about to be rengaged with the cap-strip. Fig. is a section of the pistol with the barrel in normal position, taken on line A-A of Fig. 2, looking .in the direction indicated by the arrow; Fig. 7'is a perspective view of the anvil and slideway member detached; Fig. 8 is a perspective view of the hammer detached; Fig. 9 is a perspective view of the trip detached; Fig. 1 0 is a perspective view of the trigger detached, and Fig. 11 is a perspective view of the feeding nger detached.

W In the specific embodiment of the invention illustrated in said drawings, l, 1 indip cate the side pieces forming the casing of the stock of the pistol, and 2 indicates the barrel. At the rear end of the barrel is the magazine, comprising a top 3 with depending anges 4, 5, adapted to enter the casing of the stock, between the said'side pieces l, 1, as shown, said magazine and the barrel being preferably formed of a single piece of sheet-metal. A hinge pin 6 extends through the pistol sides 1, 1 and the flanges 4, 5, near the rear end of the-magazine, pivotally securing the magazine and barrel to the stock. By virtue of this feature, thebarrel may be swung upwardly, as illustrated in Fig.' `2, to Permit the insertion of a new roll 7 of caps between the flanges 4, 5. To receive said roll, preferably one flange, as 4, has stamped therefrom to stand perpendicular thereto, the pivot 8, and the other flange as 5 is cut away, as at 9, to permit the ready insertion of the roll of caps upon the pivot 8. Upon the hinge pin 6 is also mounted a member 10, which comprises a strip of sheet metal of a width approximately equal to the distance between the side pieces l, 1, said strip having ears 11, 11 bent forwardly and perforated to receive the hinge pin 6. From said ears downward the strip forms a slideway 12 for feeding the cap strip over, and it will be noted that the slideway is inclined downwardly forward, as shown in Figs. 1', 3, 4 and 5, at an acute angle to the barrel. Above the ears 11, 11, the strip forms a vertical anvil 13, at substantially right angles to the barrel, and at an obtuse angle to the slideway 12. Beyond said anvil 13 the strip is bent downward to the plane ofthe top 3 vof the magazine, as at 14, and then extends forward, as at 15, substantially in said plane and is rigidly connected to the magazine, as by tongues 16 grasping the rear edge of the top 3 both above and below the same. The member 10 is thus rigid with respect to the magazine and barrel, and swings therewith.

To-hold'the barrel down in normal position and prevent inadvertent swinging upward, the upper edges 17 of the side pieces 1, 1, which are substantially flush with the I top 3 of the magazine, have at their forward ends inwardly bent lugs 18 which spring over the top 3 when the barrel 1s pressed down into normal position and hold the pistol and' is firmly held in such position when the side pieces 1, 1 are fastened t0- gether as will be hereinafter more fully explained. Secured to this plate 19 is the pivot 2O upon which is mounted the trigger 21, and properly positioned therefrom and also secured to the plate 19 is anotherpivot 22 upon which is mounted the hammer 23. Other pivots or studs 24 and 25 are likewise secured to the plate 19 to hold the requisite springs. One such spring 26 bears at one arm 27 against the stud 24, bows downward in its length to the t-rigger pivot 20, which pivot it encircles any convenient number of times, and from which pivot the other arm 28 of the spring projects so as to engage the rear side of the trigger 21 and tend to retain the same in forward position against a shoulder 29 formed by the casing. The tension of this spring acts always to return the trigger to the position illustrated in Fig. 1,

` when no'external force, such as the application of the operators finger, actuates the trigger otherwise in opposition thereto.

The hammer 23 is preferably made of sheet-metal and comprises a striking face 30 from which arms 31, 31 curve rearwardly downward in parallel relation to' each other and are perforated near their extremities to receive a pivot 22. Intermediate of said face 30 and the pivot 22, a trip 32 is hung between the arms 31, 31 of the hammer by means of pintles 33, 33, preferably projecting from the opposite edges of the strip of sheetmetal from which said trip is preferably made. Said trip extends forwardly downward from the said pintles 33, as at 34, and is then bent at an acute angle to extend rearwardly, as at 35, beneath the pivot 22, but still between the arms 31, 31. Ears 39 projecting from the edges of said bottom part 35 at the rear of the arms 31, 31 serve to limit forward swinging of the said trip 32. The other end of the trip or strip of` sheet-metal formino the same, extends rearwardly downward from the pint-les 33, as at 36, and provides a seat for a spring 37 to hold the saine against lateral displacement, as by prongs 38, 38. Said spring 37 lies in the butt of the pistol, extending 1n front of the stud 24 and behind the stud 25, thus exerting a forward pressure at its upper end which engages the trip 32.A One effect of such pressure is to rock the trip 32 upon its pintles 33, 33 and throw the lower forward part of the trip forward until its ears 39 engage the armsiof the hammer, as shown in Fig. 1, for instance. Another effect or function of the said spring 37- is to swing the hammer forward with its striking face in contact with the anvil.

The trigger 21 preferably comprises a piece of sheet metal folded so as to form a finger piece 40 rounded at its front side and hollow at. its rear side to receive the arm 2S of the spring 26, said finger piece rojecting from the casing of the pistol stoc At its upper end the side iianges 41, 41 of the trigger are perforated to receive the pivot 20, and furthermore said side flanges are extended rearward, as at 42, 42, to form the tripping arm of the trigger. This tripping arm extends rearward beneath the trip 32 of the hammer, when the parts are in normal position as shown in Fig. 1, and preferably has thereat a feeding finger pivoted to itself and adapted to extend upward into engagement with a strip of caps upon the slideway 12. This feeding finger is shown as a piece of sheet-metal pivoted between said extensions 42, 42 by means of lateral pintles 43, 43, and normally engaged by the forwardly projecting point or angle of the trip 32,

whereby said finger is pressed into positive engagement at its free end with the cap strip. At its lower end or beneath the pintles 43, 43, the feeding finger preferably has a tail piece 44 which is curved rearwardly upward and forms an engaging surface projecting beyond the arms 42, 42. In this preferred construction, when the trigger 1s pulled, said engaging surface of 'the tail piece 44 engages the angular shoulder of the trip 32 and swings the hammer rearward away from the anvil, the feeding finger at the same time pushing the cap strip upward to feed a cap onto the anvil.

At a position substantially as illustrated in Fig. 3, the trigger disengages and passes the trip 32 of the hammer and said hammer falls againstthe anvil under the pressure of spring 37, exploding the cap. The parts are then momentarily in the position shown in Fig. 4, but the spring 26 instantly returns the trigger to normal position when the linger-piece is released, drawing its tripping arm downward over the inclined face 34 of the trip, which trip swings rearwardly under the pressure, without disturbing the ing thedownstroke caused by forward movement of the trigger until it is again engaged by the trip and yforced forwardsibly if the pistol was fired with the barrel Y Vwholly disengages said cap strip upon its, I

pointing downward, gravity would tip the feeding finger forward during its backstroke, but even this 'can be avoided by introducing va slight amount of friction at the pivoting of the feeding finger upon the 1 trigger, so that it will stay in the position into which it is swung. lt is an important point of my invention that a feeding finger is provided which positively engages the:

cap strip to feed the same forward, and

retractive stroke.

lt is'a further feature of the invention that the slideway l2 is at an angle to the anvil 13, so as to protect unexploded caps which are approaching the anvil.

bent over. When the two side pieces l, l are joined together, the 'pivots and studs 20, 22, 24 and 25 engage at their free ends the inner surface of the side piece opposite the `one against which the plate 19 lies and thus positively hold said plate in proper position.

lt will be noted from an inspection of Fig; 2'that when the pistol 'is broken for,

loading or the barrel member sprung outward as shown, the cap strip slideway l2 leaves the feeding linger 47, so that the same would fall forwardly. downward out of position if means were not provided for preventin it. I therefore provide at the lateral e ges of the feeding nger, above the arms 42, 42 of the trigger, shoulders 48, 48 which engage said arm when the cap strip slideway l2 swings away from the feeding nger, and prevent said feeding finger from falling so far out of position that the slideway will not automatically rengage it when the barrel member is closed back into position after loading. These shoulders may be formed in any suit-able manner, but l have shown the feeding finger for its portion ahove said shoulders as of the same width as its portion having the pintles 43,43, whereby a wider bearing of the end ofthe feeding nger upon the cap strip is secured.
