No. 818,07 5. Specification of Letters Patent.
Appication filed September 9,1905. SerialNo. 277,720..
Patented April 17., 19,06,
To all whom it may concern.-
Be it known that I, MARTIN BYE, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improved Cylinder-Stop for Revolvers, of which the following is a specification, reference being made therein to the accompanying drawings.
This invention relates to an improvement in the construction and combination of the mechanism whereby the cylinder-stop device is formed with an upwardly-inclined rigid arm arranged for operation in conjunction with the lifter, which is provided with mal engagements of their upper end with the parts actuated thereby.
P indicates the cylinder-stop device pivot ally fulcrumed on a transversely-disposed pin 2 within the frame A and arranged: to have tilting movement. The stop-piece is formed with a supporting body portioncarry ing a cylinder-engaging member3 and inac cordancewith my invention is provided with a rearwardly and upwardly extendingrigi'di arm 6, having at or near its end an offset or! lateral stud 5, which normally stands in adjacence to the upper end of the lifter I, which latter is also provided with an offset lateral stud 7, adapted for upward engagementwith. the stud on the arm of the cylinder-stop- A suitable spring device is provided for pressing upon the cylinder-stop, so that its end or member 3 will normally engage the cylinder C, which has the usual external notches 4 at its periphery. Said spring device, as herein shown, consists of a coiled wire spring 9, inserted in a recess 10 in the head of the trigger F and carrying a stud 12, that acts against the under surface of the rocking stop-piece P, as best shown in Fig. 2. A spring of other form may be employed, if. in any instance preferred, for pressing forward the cylinder-stop device in equivalent manner.
The engaging means or studs 5 and 7 are disposed so that the one on the cylinder-stop arm is adjacently above that on the lifterpawl when the hammer is down or at rebound position and when the cylinder-stop is in the notch of the cylinder.
In the operation of my invention the primary movement of the lifter I, either by a pull of the trigger or by thumb cooking the hammer, causes the stud 5 of the cylinder-stop arm 6 and by movement of said parts to swing the engag ing end 3 of the stop device P from the notch of the cylinder, as indicated in Fig. 6, thereby unlocking the same and keeping the stop I indicates the lifter for automatically from the cylinder-notch for an instant sufficocking the hammer, and Gthe finger or pawl cient for permitting the starting of its rotafor rotating the cylinder. Said lifter and tion by the finger G. Then the stud7 of the finger are both pivoted to the heel of the triglifter moving upward and the stud 5 of the ger at e, and the finger is provided with a i stop device moving with the swing of the arm spring n, that acts against the lifter and 6 causes the stud 5 when it reaches a posiserves both for pressing the finger forward tion in a plane in front of the path of the stud objects being to provide a convenient, durable, and less expensive construction; to avoid the necessity of a yieldable part on the stop-piece, and to render the action stronger and less liable to become broken or deranged.
The nature of my present invention is illustrated in the drawings, wherein Figure 1 represents a side view of mechanism embodying my invention as applied to a revolver. Fig. 2 is a fragmentary view show ing the trigger, lifter-pawl, cylinder-stop, and adjacent parts. Fig. 3 represents a back view of the trigger, lifter, cylinder-actuating pawl, and cylinder-stop device. Fig. 4 is a separate plan view of the stop-piece. Fig. 5 is a front view of the stop-piece and the re turn-spring, and Fig. 6 is a view from the side opposite that shown in Fig. 1 and illustrating the primary action of the devices. Figs. 2, 3, 4, and 5 are drawn on a somewhat enlarged scale.
Referring to the drawings, the part marked A represents the frame, B the barrel, C the revolver-cylinder, D the hammer, and F the trigger, all of which parts may be of wellknown or suitable construction as heretofore 1 employed. The hammer is pivoted at d and pressed forward by the mainspring M. The trigger is pivoted at f and pressed forward by the usual spring.
and pressing the lifter rearward to afford nore the lifter-stud 7 to engage for unlocking t 7 to escape or throw off from the lifter-stud, this being effected at about the position indicated in Fi 6, and the stop device then falls 1nt o norma relation for stopping the cylinder at its next notch, while the lifter I moves upward for full cocking the hammer or until it is released by the escape of the lifter-nosed movement and until the nose of the lifter drops into the notch h at the front of the tumbler. Then the stud 7 passes under and takes position beneath the stud 5 ready for the next action. The form of the engaging faces of the studs 5 and 7 may be any suitable contour and size to effect their interengagement and throw ofi at the desired instant of action. I
By my invention an efficient and simple construction of cylinder-stop mechanism is produced in which the action is effected by the lateral engaging studs carried upon parts that permit of strength and durability in their structure. The stop device is without delicate and yieldable members, and since there isno frictional contact with or displace ment of the stop-arm while the trigger is returning to normal position on release of the trigger a trigger-spring of moderate strength or tension may be employed, rendering the action easier, while the working of the mechanism is accomplished smoothly, with less wear, and with more satisfactory result.
What I claim, and desire to secure by Letters Patent, is
