Definitions
- This invention pertains to toggle action weapons, and is particularly directed to means for causing a blow back toggle to hesitate before being tripped to recede into the handle of the pistol by gas pressure generated at the time offiring.
- This invention is particularly directed to toggle action weapons such as pistols wherein the toggle is tripped from an under-center locked position by gas pressure from the gun barrel when the gun is fired.
- the toggle after a predetermined hesitation is caused to recess into the handle of the pistol to offset the effects of firing recoil.
- a new and improved toggle action weapon which utilizes the gun barrel pressure directly to drive an undercenter toggle from its locked position to a tripped position.
- the bullet has left the barrel of the gun and the residual pressure in the gun after a predetermined hesitation actuates the toggle to its fully retracted position in the handle of the weapon.
- Recoil springs in the gun return the toggle to a predetermined under'center position which position accomplishing the function of a locked over-center position.
- Another object of this invention is to provide an improved weapon having a predetermined hesitation before being tripped to cause it to recede to a retracted position.
- a further object of this invention is to provide a new and improved toggle actuated weapon employing means for adjustably positioning the gun barrel to compensatc for various under-center locked positions of the toggle capable of firing rifle cartridges with safety.
- a still further object of this invention is to provide a weapon with a toggle design such that there is only one point of contact in the moving parts going rearward and one point of contact in the moving parts returning to their original position, so as to make the operation of the gun completely silent.
- a still further object of this invention is to provide a weapon having an under-center toggle tripped by pressure generated in the gun barrel which controls the breech pressure at the time of opening so as to eliminate or greatly reduce residual pressure at the time the breech opens.
- a still further object of this invention is to provide an adjustably positioned under-center toggle for a weapon that employs a predetermined hesitation before being tripped and is dynamically balanced so as to accomplish a smooth, consistant, and continuous pressure through out the movement of the bolt after tripping in which the line of force from the moving parts is directed to the palm of the hand thereby virtually eliminating all noticeable recoil.

- FIG. 2 is a cross sectional side elevation taken on the line 2 2 of FIG. 1 showing a gas operated toggle action weapon incorporating the features of this invention
- FIG. 3 is an enlarged fragmentary sectional view on the line 3 3 of FIG. 2;
- FIG. 4 is an enlarged cross sectional view of the weapon shown in FIG. 2 taken along the line 4 4;
- FIG. 5 is an enlarged fragmentary sectional view taken on the line 5 5 of FIG. 2;
- FIG. 6 is an enlarged fragmentary sectional view taken on the line 6 6 of FIG. 2.
- FIGS. 1 6 illustrate an example of one embodiment of this invention.
- FIGS. 1 and 2 illustrate a pistol having a frame 10, and a handle 11, a trigger 12 with trigger guard 13, and bullet magazine 14.
- a demountable adjustably positioned barrel 15 has a rear end diameter portion 16 which is received in the semi-circular bore 18 and groove 19 in the front end of the frame 10.
- An elongated clamp 20 is pivotally mounted on a suitable hinge screw 21 secured in the frame 10 so that the clamp 20 can swing outwardly as shown in FIG. 2 to the broken line position 20a.
- the outer end of the clamp 20 is provided with a mating semi-circular bore and groove to match bore 18 and groove 19 to grip the diameter portion 16 to secure the gun barrel 15 in firing position on the frame 10.
- the rear end portion 16 of the gun barrel 15 is provided with a radially disposed flange or dogs 17 which are threaded around the gun barrel.
- the outer end of clamp 20 is also provided with a mating groove 21 for receiving the flange 17.
- the surface of barrel adjacent the outer end of clamp is provided with a plurality of serrations 22 extending longitudinally of the barrel to form a ratchet type wheel arrangement around the barrel.
- a pawl 23 is mounted in clamp 20 adjacent the serrations 22 so as to engage the serrations to control the longitudinal movement of the gun barrel in either direction.
- the clamp is secured in closed position by suitable screws 25 in the frame 10.
- the bullet magazine 14 is demountably secured by the usual releasable latch in the guide sleeve 27 of the frame 10 to feed the bullets 28 into insertion and firing position by the usual bolt 29 which moves on the guide keys 30 in appropriate guide slots 31 and 32 in the frame 10 and clamp 20 longitudinally of the breech opening 33 of the rear end of the barrel 15.
- the rear end of the bolt 29 is pivotally connected by a pivot pin 34 carried in the front end of the front link 35, the rear end of which is pivotally connected by a pivot pin 36 to the front end of the rear link 37, in turn pivotally connected by a pivot pin 38 carried in the rear portion of the frame 10 to thus provide a toggle 37 for controlling the movement of the bolt 29.
- the toggle 35 37 is aligned, as shown in full line in FIG. 1, with the top surface 37a up against an adjustable locating abutment means 39 threadly mounted in frame 10 at which time the axis 40 of pin 36 is slightly below a line between the axes 41 and 42 of pins 34 and 38 so that the toggle 35 37 is in an under-center locked position as shown in full line in FIG. 1.
- a compression spring 44 is carried on a push rod 45 slidingly supported in a clearance hole 46 in a baffle 47 in the handle 11 and pivotally connected by a pin 48 to the link 37, the compression spring 44 operating between the baffle 47 and a flange 49 of the push rod 45 to normally yieldingly hold the toggle 35 37 against adjustment means 39 in under-center locked firing position of the gun.
- the toggle 35 37 is tripped from under-center locked position by gas pressure from the gun barrel when the gun is fired.
- the adjustment locating means 39 comprises an adjustment screw which makes it possible to hold the toggle 35 37 in one of a number of under-center toggle positions and to hold that position until gas pressure from the firing of the gun causes the toggle to recede into the handle.
- a pair of spring biased fingers 50 and 51 shown in FIGS. 2 and 6 are provided. These fingers are resilient in nature so that upon the application ofa given force the toggle arm 37 will over come the bias of the fingers and force them back against their spring biasing means 52 and 53 (as shown) and recede into handle 11.
- a compression spring 61 is arranged between a shoulder 62, formed around a bore 63 defined in a protruding lug 64 of bolt 29 and a ridge 62a formed in a bore 65 defined by frame 10 and clamp 20.
- Lug 64 is shown as being integral with bolt 29.
- the inertia of the bolt 29 continues rearwardly com pressing the recoil compression spring 61 until the end of the lug 64 engages a stop surface 67 of the frame 10.
- the bolt 29 and toggle 35 37 are returned to their original positions by the stored-up energy in the two springs 44 and 61. This completes the firing cycle and prepares the gun for the second firing, having picked up an additional bullet 28 from the clip magazine and placed it in the chamber when the bolt returned to its original position by well known conventional mechanism.
- a manual lever 70 is provided on the gun which when rotated by the operator clockwise against the action of spring 71 contacts the undercenter toggle 35 37 causing it to trip far enough to allow the operator to move the bolt 29 back sufficiently to allow a bullet 28 from the clip magazine 14 to enter the chamber of the gun for the first firing action.
- spring 71 Upon collapse of the toggle, bolt 29 is moved rearwardly by the operator pulling on rod 72.
- a toggle action gun comprising a frame, a handle on the frame, a hollow barrel having a firing chamber, a bolt movable in the frame axially to and from the firing chamber of the gun barrel, a toggle interconnected between the bolt and the frame, said toggle comprising a pair of pivotally connected links, the free end of one of the said links being pivotally connected to said bolt and the free end of the other of said links being pivotally connected to said frame, said toggle being movable to an under-center hesitation locked position slightly below a line between the pivotal connection of the toggle on the bolt and on the frame, and an adjustment means mounted on said frame immediately adjacent said under-center toggle for controlling the posi' tion of said under-center toggle to provide predetermined hesitation of the collapse of said toggle from its locked position, said adjustment means comprising biasing fingers mounted on the frame for holding said toggle to a given under-center position prior to firing of the gun.
- a toggle action gun as in claim 1 wherein a rachet means is provided on the frame and the barrel for actuating the barrel in the frame longitudinally of the gun to compensate for different under-center positions of the toggle.
- a toggle action gun comprising a frame, a handle on the frame, a hollow barrel having a firing chamber, a bolt moveable in the frame axially to and from the firing chamber of the gun barrel, a toggle interconnected between the bolt and the frame, said toggle comprising a pair of pivotally connected links, the free end of one of the said links being pivotally connected to said bolt and the free end of the other of said links being pivotally connected to said frame, said toggle being movable to an under-center hesitation locked position slightly below a line between the pivotal connection of the toggle on the bolt and on the frame, and an adjustment means mounted on said frame immediately adjacent said under-center toggle for controlling the position of said under-center toggle to provide predetermined hesitation of the collapse of said toggle from its locked position, said adjustment means comprising a bolt threadedly mounted in the frame and extending over the undercenter toggle for controlling in a number of possible positions the under-center lock position of the toggle.
