To all whom t may concer/n.'

Be it known that JOHN T. THoMrsoN, a citizen of the United States of America, and resident of Newport, in the county of Campbell and `State of Kentucky, have invented new and useful Improvements in Cartridge-Lubricators, of which the following is a specification. i

This invention relates to apparatus for lubricating cartridges and the like and more particularly to a combined cartridge loader and cartridge lubricator for lboth feeding cartridges into a cartridge holder and lubricating the cartridges in a single operation.

In many types of firearms employing cartridges it is desirable to lubricate the contacting surfaces between the cartridges andthe tiring chambers so as to reduce the friction between these surfaces. This is particularly desirable in certain types of automatic guns where the empty shells are lautomatically ejected before thev gas pressure Within the shells has been relieved since the gas pressure expands the shells against the circumferential walls of the firing chambers and increases the friction between said surfaces. This friction is frequently so great that the head of a shell is blown off by the gasI pressure-while the body of the shell is held against the wall of the tiring chamber, thereby rendering the gun temporarily inoperative. And even if the results of the high friction are not more disastrous the wear on the firing chamber is so excessive when the cartridges are not lubricated that the life of the gun is unduly shortened.

Tt has been proposed to lubricate eartridges at the time of manufacture, as `by coating the cartridges with a lubricant which is solid at normal temperatures, but this method entails many difiiculties which have not as yet. been overcome. VFor example, the coating is likely to become soft and sticky in hot Weather, impurities in the coating are apt to cause deterioration of the cartridges, foreign matter' is prone to adhere to the coating and carry into the firing chambers, and the guns employing such cartridges frequently become gummed. It has also been proposed to provide lubricating` brushes on the boxes or cases in which the cartridges are transported in clips so that the cartridges are brushed with lubricant as the clips are removed from the cases, but this method is obviously impractical; the method is only applicable when the cartridges are carried in clips, each carrying case must be provided with brushes, the brushes are apt to become dirty or broken -in transit, and the brushes soon become dry firearm for lubricating the cartridges, butV according to the present invent-ion the lubricating means is preferably combined with a loader for filling cartridge holders.

In its broader aspect the present invention comprises a `channel adapted to have cartridges fed therethrough and rotary means for lubricating cartridges in transit through the channel. The rotary mea-ns may comprise a brush or pad or merely a smooth surface for feeding lubricant to the cartridlges or the rotary mea-ns may be employed merely to bring the cartridges into contact with a lubricant carrying body. lVhen supplying lubricant to the rotary member the member may be caused to dip into a lubricant reservoir or the lubricant may be supplied to the member at one or more points along its path of rotation as by dropping or spraying lubricant thereupon. The rotary means may be rotated either in the same direction or in the opposite direction to the motion of the car- Y tridges through the channel but it preferably rotates in the same direction so as also to function to feed the cartridges along the channel.

In conjunction with the aforesaid rotary means I preferably employ stationary means disposed in spaced relationship to the rotary means so as to form a passageway therebetween. The stationary means is preferably circular so that the passageway is of substantially uniform width and the width is substantially equal to the diameter of the cartridges to be lubricated so that the cartridges will be engaged on opposite sides. Thus rotation of the rotary means causes the cartridges to roll along the stationary means, and also along the rotary means in an opposite sense, whereby the cartridges may be thoroughly and uniformly lubricated throughout their entire peripheries. Either one or both of the opposing surfaces of the stationary and rotary means are preferably more or less rough and absorbent so as to roll the cartridges and to carry a substantial amount of lubricant. These characteristics may be afforded by providing pads of absorbent material upon one or both of said means and in the preferred embodiments of my inven tion 1 provide such pads upon both means.

1n a more limited aspect my invention comprises a combined loader and lubricator adapted to lubricate cartridges as they are fed to a gun magazine or cartridge holder. 1n this way both the loading and lubricating functions may be effected in a single operation and with little if any more time and energy than is ordinarily needed to load a magazine or holder. My improved apparatus is adapted to any type of cartridge holder whether it be a Lewis drum, a Colt belt, the ordinary rifle magazine, or other type of holder, and this phase of the invention will be more apparent from the following description and the accompanying drawings, in which- Figure 1 is a side elevation of one embodiment of my invention showing it in operative relationship to the cartridge drum of a machine gun of the Lewis type and showing parts in section;

Fig. 1a is a view similar to Fig. 1 showing a modification;

Fig. 2 is a horizontal section on line 2-2 of Fig. 1;

Fig. 3 is a side elevational view from the left of Fig. 1, of a modied embodiment of my invention in operative relationship to a machine gun belt of the Colt type;

Fig. 4 is la horizontal section on the line of Fig. 1;

Fig. 5 is a side elevation of a further embodiment of my invention, parts being shown in section; y

Fig. 6 is a side elevation of an embodiment similar to that shown in Fig. 1, viewed from the left of Fig. 1, showing the apparatus in operative relationship to an ordinary magazine rifle.

The particular embodiment of my invention shown in Figs. 1, 2 and 1, comprises a casing 1, which is in general circular in shape, a rotary member 2 mounted in the casing to rotate with the shaft 3, a channel member` 4 mounted above the casing 1 and an oil cup 5 mounted on the casing 1. The-v rotary member 2 is mounted in the casing 1 so as to rotate in spaced relationship to the inner wall of thc casing and at the righthand side (Fig. 1) of the rotary member the cartridge passageway 5.0 between the member and the casing is of substantially the thickness of the cartridges to be lubricated.

penings

6 and 7 are provided at the upper and lowerl ends of the passageway 50 and the channel member 11 is arranged to extend upwardly from the upper opening (5. The channel -l is open on one side as shown in Fig. -l and is provided with two projecting ribs or ridges S near the base of the channel te fit into the grooves at the bases of the cartridges. Thus, when cartridges are fed into the channel at the top with theshoulders at the bases ofthe cartridges fitting into the grooves behind the ribs 8, the cartridges are guided along the channel way and are held therein notwithstanding the fact that they project a con` siderable distance out of the channel. The ribs or ric ges 8 are preferably extended along the passageway in the casing shown in Fig. 2, so that the cartridges are guided thereby during their passage through the casing.

The opposing faces of the wall 9 of casing 1 and of the rotary member 2 are covered with lubricant carrying pads comprisy ing layers 10 and 11 of felt or other suitable lubricant absorbing material and covers 12 Vand 13 of leather, fabric, or other suitable material for covering the felt pieces 10 and 11. The oil cup 5 may be of any ordinary or suitable type and is threaded into an opening in the top of the casing 1 so as to communicate with the interior of the casing through the opening lll. A handle 15 isl fitted to the outer end of the shaft 3 for the purpose of rotating the member 2. A projecting ridge 16 is provided at the bottom of the casing adjacent the opening 7 so as to form a concavity 17 adapted to contain a pool of oil or other lubricant. rThe projection 16 extends upwardly somewhat above the level of the lower side of the rotary member 2 so that the rotary member may if desired dip into a pool of oil contained in the concavity 17. At 18 is represented a drum of the Lewis type with its filling opening 19 disposed below and iu alinement with the opening 7 at the bottom of the casing 1.

The operation of the apparatus shown in 1, 2, and 4L is as follows: Cartridges are ted into the channel Ll from the top, as for example. from clips containing` live cartridges cach, these cartridges passing by gravity to the passageway 50 between the rotary and stationary lubricating pads in the casing 1. The width of this passageway is preferably such that the cartridges wedge in between the two lubricating pads and do not slide freely therethrough. Nhen the rotary pad is rotated in the direction of the arrow (Fig. 1) by mea-ns of the handle 15 the cartridges are rolled downwardly along the stationary pad 12 and thence pass through the opening '7 into the drum 18 where they are forced around the passage 'way in `the drum `by the weight of the cartridges and 'by the impelling act-ion of the rotary pad 2. As the cartridges are rolled downwardly along the stationary pad they .also roll upwardly relatively Ato `the rotary pad. Thus lubricant carried by the pads is effectively and uniformly distributed over the peripheral surfaces of `the eartridges.- he lubricant may be allowed vto accumulate in concavity 17 so that the rotary pad dips' thereinto, but I preferably supply oil to thepads merely by dropping it from the opening 14 directly to the rotary pad, the rate of `supply ,being so regulated that no excess of oil will be permitted to accumulate in the concavity 17. rilhe oil dropped to the rotary 'pad is carried around to the cartridges and lthey in turn transmit a part of the oil to lthe stationary pad. Obviously a second lsource of oil sup'- vply may if desired be associated with the stationary pad.

:instead of making both of the lubricating surfaces relatively rough and absorbent one or both of these surfaces may ifdesired be made smooth. For example, the wall 9a (Fig. la) may present merely a polished surface so that the lubricant would be applied wholly from the rotary member. Moreover a very light coat of lubricant or other substance may be applied to the cartridges or other articles by making both the wall 9 and the rotary member 2a smooth and hard as shown in Fig 1a. When so constructed vthe rotary member may advantageously be rotated in a counter clockwise direction that is, in a direction opposite to the direction of motion of the cartridges. The cartridges may then be permitted to pass through the passageway solely by gravity and the counter clockwise motion of the rotary member tends to rotate the cartridges in a clockwise direction.

The embodiment illustrated in Fig. 3 is similar to that shown in Figs. 1, 2 and l in that it comprises a casing 1 containing a rotary lubricating member such as 2 in Figs. 1, 2 and ll, a feed channel 4, an oil cup 5, etc. However,the apparatus in Fig. 3 is further provided with a base 2O having au openimT 21 passing entirely therethrough inunediately below the opening 7 (Fig. 1).

ln the opening 21 a bolt 22 is reeiprocat# ably disposed. The bolt 22 is provided with an opening 23 `through which extends a lever 24 pivotally mounted at 25 on a bracket 26 screwed to the side of the channel 4. The lever 24 is provided with a longitudinal slot 27 throughout the, central portion thereof and a crank 28 coperates with the slot 27 to oscilla-te the arm 24 back and forth about the pivot 25. The crank 2S #is mounted at kone end of a shaft 29 .and

upon the other end of the shaft yis mounted a handle 30 for rotating the shaft. Upon .the shaft 29 intermediate its ends is fast a bevel spur gear 31 in mesh with a bevel spur gear 32 fast on the end of a shaft corresponding to shaft 3 in Figs. 1 and 2.

The operation ofthe apparatus in Fig. 3 is as follows: WV hen the handle 30 is rotated the rotary pad in the casing 1 is rotated as in Figs. 1 and 2 .and the rod 22 is reciprocated to and fro. VJhen the rod is in extreme rearward position a cartridge is permitted to pass through the opening 7 (Fig. 1) to the opening 21 (Fig. in advance of the rod and when,` the rod is then advanced the cartridge is advanced as shown at 33 (Fig. A cartridge belt 34; of the Colt type is fed along in front of the opening 21 by suitable mechanism not shown or by Yhand and the cartridges are fed into the openings in the belt by means of the reciprocating rod The modification of my invention illustrated in Fig. 5 resembles the modification vshown in the other figures in that it coinprises a rotary lubricating member disposed at one side of a channel so as to spread lubricant over `the peripheral surfaces of the cartridges as they are fed past the rotary member. It also resembles the other modifications in that it comprises an oil reservoir in which the rotary member' is adapted to dip. The construction in Fig. 5 comprises a Ychannel as in the other figures, casings 35 .containing rotary brushes 36, the brushes Vbeing disposed on opposite sides of the channel. The brushes 36 may be of any suitable construction adapted to spread a thin film of lubricant over the surfaces of the cartridges and any suitable means may be employedV to rotate lthe brushes. The brushes may be driven in the same or opposite directions or they may be arranged to be rotated in opposite directions by the cartridges .passing therebetween. lhen rotated in the same direction, for example in a clockwise direction, they have a tendency to rotate the cartridges in the saine direction, one brush moving upwardly along one side of the cartridges and the other side moving downwardly along the other side. This serves uniformly and effectively to lubricate the cartridges throughout their entire surface. Owing to the fact that the cartridges extend outwardly from the channel7 one side of which is open, they can be lubricated throughout substantially their entire' length by means disposed wholly in front of the channel.

lThe modification shown in Fig. 6 is similar to that shown in Figs. 1 and 2, except in that it is adapted to lill the magazines of ordinary service rifles instead of filling `a drum of the Lewis type. The casing 1 v.is socfshaped at the Ybottom that it willifit into the receiver 37 of a rifle 38 with the opening 7 (Fig. l) disposed in alinement with the receiver openings so that cartridges 39 may be fed into the magazine 40 of the drum. The modification in Fig. 6 also differs from that shown in Figs. 1 and 2 in that the rotary lubricating member in the casing l is driven through spur gears l1 by handle 42 instead of directly by a handle as in Figs. l and 2.-

The operation of the modification shown in Fig. 6 is as follows: The lubricating apparatus may be rigidly mounted from the side in any suitable manner sok that a rifle may be placed thereunder as shown in the figure. Means may be provided for holding the rifle in this position but in view of the short time required to fill the magazine of a rifle it is preferably held in position during lling merely by hand.

ln Figs. l to 4: and Fig. la, the channel 4C and passageway 50 together form a guideway through which cartridges may be ted downwardly from the receiving opening at the top of channel tto the delivery opening at the bottom oi" the passageway 50, the cartridges being lubricated in transit through this guideway. Likewise in Fig. 5 the channel a comprises a guideway in which the cartridges are lubricated in transit from the receiving opening at the top to the delivery opening at the bottom. In Figs. l to 4f and in Fig. 6 the cartridges are fed through the guideway partly by gravity and partly by the rotating drum, the proportion between the two effects depending upon the snugness with which the cartridges ft between the two circular members, while in Fig. 5 the cartridges are fed solely by gravity.

While my improved apparatus may be employed at any locality for applying lubricant or other coating to cartridges or other articles, I have adapted it especially for use at the locality where the cartridges are to be employed, inasmuch as many disadvantages are eliminated'by lubricating the cartridges at the point of use as they are being fed into the holder from which they are to be fired.
