SHOCK ABSORBING STRUCTURE FOR FIREARMS Filed May 16, 1929 INVENTOR ATTORNEY Patented Dec. 2, 1930 UNETED STATES PATENT caries GROVER R. LEDFOR-D, OF SAN JOAQUIN, CALIFORNIA SHOCK-ABSORBING STRUCTUREFOR FIREARMS Application filed May 16,

that the shock of the recoil will be absorbed within or between these parts instead of being solidly transmitted to the shoulder of the shooter, as is the case with the ordinary rigid constructed firearms.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly efiective for the purpose for which it is designed.

Fig. 1 is a side elevation of my shock absorbing stock and butt construction, one of the cover plates being partly broken out.

Fig. 2 is a sectional elevation of the structure.

Fig. 3 is a sectional plan taken on the line 33 of Fig. 2.

Referring now more particularly to the characters of reference on the drawings, the butt 1 of the firearm is a member separate from the stock and is provided with a longitudinal and relatively large slot 2 which extends from the front end of the butt toward the back and is open to both sides of the same. The top and bottom of the slot are lined with smooth faced metal strips 3, while the sides are covered by removable metal plates 4, the butt being recessed about the slot as shown at 5 so that the plates set into the butt flush with the exterior thereof. The length of the plates is also such that they project ahead of the front end of the butt a short distance.

The rear end of the stock 6 of the firearm is provided with a rectangular tongue or ex tension which has a close sliding fit in the socket formed in the butt by the strips 3 and plates 4. This tongue normally pro ects nearly to the rear end of the socket so that a relatively long and substantial bearing area is obtained between the parts, maintaining them rigid against lateral or vertical distortion.

A fairly stifi compression spring 8 is disposed between the adjacent ends of the tongue and socket, being partly countersunk in recesses 9 provided in these parts so that a relatively long spring may be had w th only a 1929. seriaino. 363,549.

comparatively small space between the parts themselves. A pin 10 is preferably disposed inside the spring so as to prevent the same from possibly buckling without interfering with the necessary compressive action there- The top of the stock is in line with the top of the tongue but the bottom of the stock alines with the bottom of the butt so that a vertical ofiset 6a is formed at the forward end of the tongue, which offset is spaced ahead of the adjacent end of the butt the same distance as the spacing between the rear end of the tongue and socket. Said rear end space is of course enclosed in any event while the front space is covered by a plate 11 secured to the butt and which overlaps the adjacent end of the stock in close sliding relation therewith. In this manner the stock may move rearwardly relative to the butt without 7 faces. To limit the outward movement of the 8 same and so that the spring is always maintained under a certain compressive strain a bolt 12 projects vertically through the butt centrally of the width of and across the slot 2 and intermediate the ends of the tongue; passing through a longitudinally extending vertical slot 13 cut through the tongue. The plates 4 are secured at the back to the butt by vertical spaced screws 14. This cannot well be done at the front end however since the material of the stock to the sides of the plates rounds ofi somewhat sharply. A single bolt 15 is therefore used to connect the plates adjacent their front end, said bolt passin through a longitudinal transversely cut slo 16 provided in the tongue. This slot is of suflicient length to enable the necessary longitudinal movement of the tongue to be had without engaging the bolt and placing a mo strain on the relatively weak rear holding screws of the plates.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. In a rifle or like firearm, separate stock and butt portions, a tongue projecting from the rear end of the stock and sliding ina socket cut in the butt over the full width thereof, a compression spring between the" rear end of the tongue and the butt, plates covering the sides of the socket and engaging the adj acent surface of the butt, securlng means between the butt and the plates at their rear ends,and a bolt between the plates adjacent their forward ends projecting through a longitudinal slot in the tongue and connecting said plates together.

2. In a rifle or like firearm, separate stock and butt portions, a tongue projecting from the rear end of the stock and sliding in a socket cut in the butt, the bottom edges of the butt and stock being substantially in longitudinal alinement andthe adjacent edge of the tongue being parallel to but above said edges, a compression spring between the rear end of the tongue and the butt, and a plate secured to the bottom of the stock at the front and bridging the gap between the stock and butt and slidably engaging the stock.

In testimony whereof I afiix my signature.

GROVER R. LEDFORD.
