GUN.

Application filed .Tune 29, 1916, Serial No. 106,675. Renewed November 22, 1922.

To @ZZ whom t may concern Be it known that I, JOHN LUND, a citizen of the United States, residing at Bethlehem, Northampton County, State of Pennsylvania, have invented certain new and usei'ul Improvements in Guns, of which the tollowing is a specification.

This invention relatesto guns and more particularly to guns and carriages which are separable into convenient parts, for transportation. u

The main object of the invention is to provide a gun so constructed that it may be quickly and easily knocked-down or set-up without in any way separating the delicate moving parts such as the recoil mechanism, elevating mechanism and traversing mechanism. i

These and other features of the invention will be described in connection with the drawings and pointed out in the appended claims. i

In the drawings, in which like reference characters indicate the same part,

Figure l is a side elevation of the gun and carriage, certain parts being broken away to show other and hidden parts in section;

Figure2 is a side elevation of the gun bari rel and sleigh for supporting the same, the latter appearing in section;

Figure 3 is an end elevation of the parts shown in Figure 2 as seen from the right;

end; l

Figure 5 is a sectionall view on the line 5-.5 of Figure 4 showing the manner of connecting the front end of the gun barrel and the sleigh;

Figure 6 is an end elevation of the cradle and part of the elevating mechanism;

` Figure 7 is a side elevation of the cradle and part of the elevating mechanism;

Figure 8 lis a sectional view taken ou either of the lines 8 8 of Figure 7 Figure 9 is a side elevation of the top carriage, the axle and plate locked to the saine being shown in section;

s Figure l0 is a front elevation of the axle and plate, showing thejmanner of locking the latter to the axle.

Mountainy guns `are generally knocked down for transportation, by separating the l.parts of the gun whichk move relative to each other in firing or adjusting the gun. Thus,

in removing the gun barrel, the guides on Figure 4 is an elevation of the opposite Again in rel with the consequent injury to the gun, by

providing means whereby the gun maybe dismantled or knocked-down withoutseparating any of the parts which move on each other when tiring or adjusting theugun.

As shown inv F iguresl and2, the gun barrel 2O is adapted'to be attached to a sleigh 2l. This sleigh reciprocates on guides '3l provided on the cradle. The gun barrel is connected to the sleigh 21 by means at the front and rear ends thereof.y At thelfront end the gun barrel is provided with two prongs 22, which are adapted to iitin corresponding recesses 23 formed near the end of the sleigh. While two prongs are shown, v

it is obvious that a greater' or less number' might be used. y At the breech end of the gun a.. downwardly extending lug 24 is providedL which is adapted to extend into a hollow or recess 25 formed in the corresponding end ot the sleigh. As shown, the rear face of the lug 24 is substantially perpendicular to the axis of the barrel. The opposite face,

however, is inclined so that the lug has the form of a wedge. The straight side ofthe lug is adapted to contact witha corresponding straight surface in the recess 25 and the inclined side of the lug cooperates with a similarly inclined surface in the `recess 25 so that when the lug is introduced into the recess it will tit tightly therein because of the inclined side. The sleigh is formed with a substantially semi-cylindrical seat 26 and the lug 24 is provided with a corresponding seat 27 which is adapted to register with thc 'first seat, the two seats when in register forming a complete cylindrical surface. A pin28 is rotatively mounted andv adapted to nt in they seat 26 andvis provided with a handle 29 whereby it maybe rotated. At the oppositev end from the handle it is threaded and a nut 69 fitted thereon vso that the pin may beheld in proper position. On one side for a distance substantially kequal to the breadth of the lug 24 the pin is ioov slabbedofto provide a flat surface 29. The arrangement ot this flat surface is such that when the pin is rotated` to proper posi the said surface will lie yflush with .the ccntacting surfaces ot the lug 24 and recess 25. thus permitting` the lug to be withdrawn troni the recess 25. it will therefore be apparent that it vthe pin 28 is turned to the above mentioned `position that the `lug 24 may be withdrawn from the recess and thereafter the prongs 22 inay be disengaged trom the recesses 23 by moving the barrel ot theV gun slightly in a forward direction. rlhus the gun barrel will be disconnected from the sleigh 2l and without disturbing any parts which move on each other while the gun being tired. The sleigh 2l provided at' opposite sides with ways 3U- which are adapted to slide on vthe guides 3l carried by 'the cradle. iis shown in Figure i., the end of the sleigh which has the recess 25 formed therein is connected to the recoil mechanism 32,-the latter being carried in a cylinder 33.

rlhe structurewhereby the cradle may be separated from the top carriage will now be described. The trunnion plate 34 is riveted to the cradle and 'carries the oppositely e1;- tendingtrunnions 35. which are adapted to seat inthe trunnion bearings 36 on the top carriage andto be held in place by hinged caps (not shown). Connectedto the cradle by means presently to be' described is an elevating segment 37, which is adapted to be engaged by'worin 38, the latter` being carried bythe top carriage. Guides 37 on either side ot this elevating segment engage corresponding =grooves Aot the elevating worm bearings 38, preventing these two parts from being` separatedexcept by means ot continual turning ot the worm until these two members are disengaged. rl`he upper side ot the elevating segment is formed with two upwardly projecting

lugs

39 and 40, which are adapted to engage corresponding lugs 4l and 42 formed on the trnnnion plate. ris clearly shown in Figure 7, one of the faces ot thelug 40 and a corresponding tace ot the lug 39 are inclined and adapted to engage correspondingly inclined surfaces on the trunnion plate. The

lugs

39, 40, 4l and 42 are ,termed with alined bores 43 in which is adapted to seat apin 44. provided with a handle 45. The wall between the bore 43 and the bottom ot each of the lugs 41 and 42 is cut away as at 46 in Figure 8. Adjacent the two lugs 41, 42 the pin 44 has its opposite sides slabbed o1'i` as at 47 `and 48 so that when the pin is turned with the two slabbed surfaces substantially vertical the trunnion plate and its connectedcradle may be renioved :tronithe segment, the pin 44 sliding through the openings 46. It is therefore apparent that the cradle may be separated from the top carriage without disturbing` the 'two plates 50 spaced. end to end which are provided with lugs 5i. 'forming grooves 52 adapted to lit and Slide on the guides 53 provid'efil on a traversing plate 54. Any suitable traversing mechanism is provided and operative between the plates and 54 vwhere- Y by these plates maybe moved longitudinally with respect to eachother. is Vshown a worm 'TO carried by plates 50 engages-teeth 54 on the edge of plate 54. taclied tothe plate 54 and adjacent one end is a pair of downwardly extendingprongs 55 and at the other end is another pair ot oppositely projecting prongs 5G. The two prongs o the pair 55 and likewise the pair 56 are each spaced apart so as to straddle the axle 57. The axle is formed with two transversely eX- tendingg; bores 58 which are located so as to register with the inside curved surfaces of the prongs 55and 56. A pin 5,9 is adapted to tit'in each ot the bores 58 and is provided with a handle 60 for rotating the same. Adjacent the

prongs

55, 56 each ot the pins 59 slabbedotf as shown at 61 in Figure l0 so that when the said slabbed off portion is arranged kvertically the end (32 ot' the prongs nia-y pass by the pin so that the plate r54 may be disconnected troni theaxle. is clearly shown in Figure 9 the pins 59 are formed with a groove 63 into which is adapted to project a set screw G4, t'or `the `purposeotl holding` the said pins @longitudinally in position. A. spring pressed pin`65 maybe provided and adapted to engage recesses 66 in a pin 59 'to hold the Said pin in'either a. position which locks the plate 54 to the axle or onewhichpermits it to be removed there from.

In the operation ot the construction which has just been descrilied the gun barrel is removed from the sleigh by turning the pin 28 through substantially G00 'troni its locking position, then raisin-p; the corresponding end ot the gun barrel, then moving' the` gun barrel slightly Aforward to disengage `the prongs 22 at the 'forward end ot the cradle. The gun barrel is then entirely free of the sleigh. The sleigh` andI cradle which includes the recoil mechanism may now be removed from the top carriage by turning the 'pin 44 through ,substantiallyQOO Aand the additional operation ot opening the hinged trunnion caps previously referred to. The next; step isV to turn the pins 59L each through substann tially 1809. vThe plate 54, together with the assembled traversing and elevating mechanisin. or in other words the top` carriage, may then be removed from the axle.

It is obvious that a gun construction has been provided which permits the knockingdown or disassembling of the same for shipment without disturbing any of the parts which move on each other when the gun is being fired or adjusted.
