BRUSH FOR CLEANING GUNS AND THE LIKE.

Specification of Letters lPatent. i Patented Mar, 12, 19181.

Application filed April 6, 1917. Serial No. 160,288:

To all whom t may concern: Y

Be it known that l, GILBERT C. BEMIs` a citizen of the United States, residing at "a Torcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Brush for Cleaning Guns and the Like, of which the following is a speciiication. l

This invention relates to a brush, which can be made of any shape according to the use to which it is to be put, but is made preferably of cylindrical form so that it can be used for cleaning out cannon and the like.

The principal objects of the invention are to provide a simple, convenient and light construction which can be made-up of v a number of separate replaceable elements of such a character thatthe brush will not be excessively heavy and the brush fillers can be replaced readily and at small ex- Y pense when worn; to provide a construction in which the bristles will have a max imum cleaning effect so that the device will remove particles of copper and other metals from the interior of the bore of 'a gun; to provide an improved way of holding and clamping the brush fillers;y to provide Va simple yet effective means for more positively holding the fillers in position by 'applying pressure to the circumference of the brush; to provide means whereby 'the depth to which the fillers are placed'in the brush structure will be gaged by a. member separate from the separator disks which` provide theV sockets therefor so that the cost of these disks .can be reduced by eliminating the necessity of some of the precision of the operations necessary to make them; to provide means for supporting a brush, particularly one with soft bristles, in spite of the weight of the parts so that when it is used in cleaning out a cannon both its upper and lower bristles will come into action against the corresponding interior surfaces of the gun; to provide for eXtreme lightness by making the parts of aluminum, and especially to provide a construction which will be particularly eiiicient and durable for performing the necessary operations in cleaning heavy guns.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a side viewv ofl a brush of small size constructed in accordance-with this invention with parts in central longitudinal section;

Fig. 2 is a sectional view of the same on the line 2-2 of Fig. 1; Y

Fig. 3 is a face view of one of the separator disks for holding the brush elements in position;

Figl is an edge view of the same;

Fig. 5 is a view similarto Fig.v 1 showing a modied construction; v Fig. 6 is a face view of one of the y,disks used thereon; Y

Fig. 7 is an edge view of the same;

Fig. 8 is a view similar to Fig.' 1 of another modication in which the separator disks are made' of wood,land i Fig. 9 is a--sectional view in Fig. 8.v

Referring first to the first sheet of drawings, it will be seen that'the gun cleaning brush as'shown therein comprises a hollow The core 10 is' provided with a ange at one end and with` a washer 14: at the other end. These are both arranged to Ihave full thickness at their edges, but are recessed elsewhere as at 15 .so that the full width edges at their circumference will separators in the form of aluminum disks 16 .when fastened in position by meansof a nut 17 on the end of the core 10. This nut is also constructed in the same way preferon the line- 9 9 `press against the outer edges of la series of ably, so as to get the pressure out at the ,l

circumference. v

The disks 16 are provided with'semi-circular recesses 18 on both sides, but these are not in registration with each other on the two "sides, being offset slightly as indicated for a purpose that will appear. All of these disks or separators except the two end ones are provided with recesses on both sides, and those in the adjacent disks register with each other so as to form cylindrical sockets for the butts 21 of a series of brush fillers 20. The recesses are not fully semieircular so that when the separators are clamped together the pressure will come on the butts 2l and hold them firmly.

These metallic butts are shown as provided with circumferential grooves 22, one in each one, for two purposes. One purpose is to enable them to pinch the bristles '.43 which in this form are indicated as of wire, and the other purpose is to arrange for holding them firmly in position and prevent their ,displacement radially. It is to be noted that the gripping of the disks at their circumferences 1n the manner that has been described serves to accomplish this result, but an additional means is also Vshown in the form of a series of circular metallic plates 24. These'plates are placed between eachV two adjacent disks but are not intended to fill the entire space between them because it is desired to get an efficient gripping action on the bases ofthe brush elements, and consequently the disks are not intended to touch each other or theV plates 24k when tightened up against the brush butts. But theseplates are thick enough so that they are held substantially in stationary position, and they are provided with notches 25 into which the brush ends set, and these notches are Aprovided with opposite projections or lugs Q6 integra-l with them which t into the circumferential recesses 22 and .positively prevent displacement of the brushes radially in addition to the action above described.

Another feature is shown in these figures which is ordinarily not used when the brush elements are provided with metallic bristles, but is of particular use when they are made of soft bristles. ln that ease on accountof the weight of the brush there would be a tendency for it to drop down when used for cleaning guns so that the upper brushes would not acton the inner surface of the bore. For the purpose of preventing this and supporting the brush in a substantially central position a member 28 is provided between the two circumferential rows of bristles for supporting theV brush at the bottom in ease this difliculty occurs. InV this form .of the invention this is shown as an integral circular projection on one of the disks 16 and as extending all the way around so that they will'not ydig` in to the surface of the cannon.

In the form shown in Figs. 5, 6 and 7 55 many of the same features are illustrated, and this form also is made of aluminum. Here the central core 8O is of larger diameter than in the other case, but is arranged in a similar manner except that it is open at the end. In this case a ring Salis arranged at the outer end and held toward the flange 33 by bolts 35 which extend through cored recesses 87 in the cast aluminum disks 36. It will not be necessary to describe these disks as they are shown as made substantially like those shown in Fig. l with the omission of some parts, and they are cored out instead of solid. rllhey support thebrush elements Q0 and in this ease the plates 24E' are omitted, but it will be seen that the bolts' are located at the circumstances substantially so as to grip the outer edges of the brush butts and prevent their displacement. This is van important feature either in this form orin the form shown in F ig. l because as made heretofore the pressure Vhas been uniform from end to end and has'been distributed along the length of these 'metallic butts so that it was too much divided up and thej7 sometimes got'loosened and came out, thus necessitating loss of time and sometimes injuring the device being cleaned. The core 30 limits the position of the brush fillers.

In theV Vform shown in Figs. 8 and 9l a large size cannon cleaner is also shown, but in this case the metal core 40 is provided with a largerk flange El which' is recessed out at the center at and the nut 4a lis C arranged in the same way so that pressure is secured at-,the extreme circumference. In this case, however, the core 40 does not serve any function except to center a series of voeden separator disks i6 and receive the fastening nut 4t?. In this ease I haveshown the sheet metal plates 24 having the re? cesses 25 for the butts ofthe brushes and the projections 26 entering the vcircumferential grooves 22 as in Fig. l. rEhis is an important feature in the case of a large wooden brush especially because without it lf disks would have to be bored to provide the sockets for the brush heads, and this boring would han@ to be done with a great deal of precision in orderthat theends of the bores might serve to limit the position of the brushes uniformly and cause them to project to uniform distances from the circumferences of the disks. This I avoid by the use of these plates which are stamped out very economically and permit the boringI of these sockets to nonuniform depths without injuring the brush or making it noncircular. Y

Although l have illustrated and described several forms ofthe invention l am aware of vthe fact that' other modifications' can be distances from the center, and means separate 'from said separators for limiting the position of said llers. i
