'To all wh o'm, it mag concern:
known that I, SAMUEL Gr. G znnn,
Be. it captain, Ordnance Dept, U. S. Army, a citizen of, the Unitcd States, stationed at Washington, D. 0., have invented anImprovement in Adjustable Shoulder-Rests, of which. the following is a specification.
The invention described herein may be used by the Government, or any of its officers oremployeesin prosecution of work for .the Governmennor byany other person in theUnited States, without payment of any pending V inafter.
'ed on a hollow Specifically, the improvement resides, z'nt er aha, 1n a shoulder rest having a length-c wise adjustable gun attaching portion, pref ,erably comprising telescoping sections.
The improvement rcsides, also, in an adjustable shoulder-rest piece, slidably mountsheet metal standard, which is shaped in a novel mannerfrom a single piece of material and suitably secured to the gun-attaching portion.
' Theinvention 1s graphically shownin the i accompanying drawings, whichshow an exemplary construction embodymg the underlying principles of the invention. Like reference characters designate corresponding 7 parts throughoutthe several views, Briefly described Figure 1 is a view in side elevation of my improved shoulder-rest;

Fig. 10 is a similar view of the inner telescoping section; and
Fig. 1 1 isa collective, detail viewof the support ng collar for the. aforesaid gun-attachlng port1on, which collaris secured to the shoulder-rest standard.
Referring, now, in det ailto the drawings: The gun attaching portion'of the shoulder-rest comprises, i in this instance, two telescoping tubular members, an outer men'iberv .1 and an inner member 2, whereby said portion is adjustable asto length.
The outer member (shown in detail in Fig. 9) 1S P1QV1d6ClWltl1 a longitudinal slot 3. extending from one end thereof, to. permit of contraction of the member by suitable clamping 1neans, c ompr'ising, in thisinstancefa strap 4 preferably welded to the exterior of the tube 1 and carrying a pivoted clamp screw 5, carrying a clamping nut 6, whereby the tube may be clamped around a gun. The clamping means described formsno part of the joresent inven- 'tion, since it is fully shown and described in my said co-pending application.
Thetube 1 is also provided with a second longitudinal slot 7 through which projects a threaded clamp bolt 8, which passes, also, through an aperture 9 in thetinner tube 2. On the bolt 8 is screwed a wing nut 10. Between the nut andthe tubel and between the head ll of the. bolt and the inner tube 2 are disposed washers 12-12, each having, as
shown in Fig. 2, a curvilinear face conformmg to andfbearlng against the circumference of the tube.
"It will thus be noted, that when the nut 10 is loosenechthe tubes 1 and Q may be moved relativeto each otherto lengthen or shorten the gun-attaching portion of the nels or slide-ways 15-15 shoulder-rest, and that the tubes may be secured in the desired adjusted position by tightening the clamping nut.
The inner tube 2 is suitably secured to a standard 13 (shown in detail in Figs. 5 and 6) which, from the standpoint of practicability in manufacturing and lightness in weight, is preferably of sheet metal cut out and bent u from a single blank, and the longitudinal over-lapping ends lll welded together.
Two opposite sides of the elongated hollow sheet metal member thus formed are bent or crimped in, as shown in Fig. 6, to provide two longitudinally-extending chanto guide a slide 16, constituting the shoulder-rest piece (hereinafter more particularly referred to), in its movement on said standard 13. Each of said crimped-in portions is provided with a longitudinally extending slot 17, for a purpose presently appearing.
Each crimped-in portion, at each end thereof, carries a tongue or lip 18, the two tongues, at each end, being bent toward each other so that their free ends meet, as clearly shown in Fig.
be welded together. By this peculiar con struction, the hollow standard is braced and strengthened against collapse or buckling inward of the walls thereof. It will be noted that the standard 13 is in one piece and that it is simple and practical from a mechanical standpoint, being easy and cheap to manufacture and light in weight, while possessing the requisite strength and durability.
The means for securing the tube 2 to the standard 13 may obviously be variable. An exceedingly simple and efficient form is shown in the drawings and will now be described.
A collar 19 (shown in detail in Fig. 11) is provided with a lateral circumferential flange 20, which may be welded to a side wall of the standard 13. The collar may obviously be threaded interiorly, and, in such case, the tube 2 would, of course, be exteriorily threaded at its end, so that it may be screwed into the collar. However, I prefer to make the collar unthreaded and to slide the end of the tube 2 therein, and then weld the collar thereto.
Adjustably supported on the standard 13 is the slide 16, constituting the shoulder-rest piece, shown in detail in Figs. 7- and 8. The slide is preferably formed from a single piece of material and comprises two side walls, which are crimped or bent inward, as shown, to form longitudinally-extending ribs or tongues 2121, which fit in the complemental slide-ways 1515 in the standard 13, whereby the shoulder rest piece is guided in its sliding movement on 6. Such meeting ends may' the standard. The shoulder-rest piece is 6 provided with a wing 22 havln a curvilinear face 23, to fit the shoul er of the user, and which face may be transversely serrated, or otherwise roughened, to prevent slipping when the shoulder-rest piece is in use.
The crimped-in portions 2l-21 are r0- vided with diametrically opposite e orations 24, through which projects a t readed clamping bolt 25 carrying a wing nut 26, and which bolt passes through the slot 17 in the standard 13, whereby the ribbed 0rtions 2121 of the slide may be tig tl clamped against the standard and the slidz or shoulder-rest piece thereby securely frictionally held in adjusted position.
Having described my invention, what I claim as new and desire to secure byLetters Patent, is
1. A shoulder rest comprising a 'gun attaching portion adjustable with reference to length, a standard carried thereb positioned transversely thereof, and a sli e, constituting a shoulder-rest piece, adjustably supported on said standard. v
2. A shoulder-rest. comprising a gun at taching portion in two telescoping sections positioned transversely thereof, a standard carried by one of said sections, and a slide, constituting a shoulder-rest piece, adjustably supported on said standard.
3. A shoulder-rest comprising a gun attaching portion intwo telescoplng sections, one of said sections being provided with a longitudinal slot extending from one end thereof, and with a second longitudinal slot, clamping means encirclingsaidfirst mentioned slotted portion for contracting the same around a gun, clamping means passing through said second slot and through the other section. for securing saidsections in adjusted position, and astandard transversely carried by one of said sections, and a slide constituting a shoulder-rest piece adjustably supported on said standard.
4. A shoulder-rest comprising a standard formed from a single sheet metal blank and bent longitudinally to provide side walls, two of said walls being bent inwardly to provide longitudinally extending channels, a slide, constituting a shoulderrest piece, having complemental bent portions engaging said channels, and means for holdin the slide in adjusted position on said stan ard.
5. A shoulder-rest comprising a standard formed from a single plece of metal and bent longitudinally to provide sidewalls, two of said walls being bent inwardly to form longitudinally extending channels; means for bracing said standard against collapse, comprising tongues carried thereby and bent toward each other with their free ends abutting; a slide having complechannels; means for bracing said standard 10 against collapse, comprislng tongues carried thereby and bent toward each other with their free ends abutting; a slide having complemental bent portions engaging said channels; and adjusted position on said standard.
