To all whom t may concern.'

Be it known that I, WILLIAM L. SECHLER, a citizen of theUnited States, residing at Braddock, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Irojectile-Protectors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and inexpensive Ayet an efficient and durable device for encompassing the usual copper packing rings of projectiles to guard the same against injury during handling and transportation, and with this general object in view the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application, and in which,

Figure 1 is a side elevation of a projectile Showing the application of one of the protectors thereto;

Fig. 2 is an enlarged longitudinal section of the protector applied;

Fig. 3 is a vertical transverse .section on the plane of the line 3 3 of Fig. 1 showing more particularly the construction of the Split laminated ring and the joint for securing the ends thereof together under ordinary circumstances Fig. 4 is a detail section similar to the upper portion of Fig. 3, but showing the manner in which the joint may be Severed;

Fig. 5 is a duplicate of Fig. 1 with the exception that it illustrates a different form of protector;

Fig. 6 is a longitudinal section of tector shown in Fig. 5;

Fig. 7 is a rear end elevation thereof with parts broken away and in section;

Fig. 8 is a detail section similar to the upper portion of Fig. 3 showing a slightly different form of construction; and

Fig. 9 is a detail transverse section through main guard ring, showing another manner in which the same may be constructed.

In the drawings above briefly described, the numeral 1 designates a common type of the 4proprojectile while 2 has reference to the usual 'another'.

copper packing ring at the rear end thereof, said ring being provided with the usual grooves 3 which are packed with grease before shipment of the projectile. It is the object of the present invention to retain this grease in the grooves and prevent the entrance of dust and the like thereto as well as to guard the ring 2 against injury during handling or transportation. To attain these results, the improved protector' may be constructed in a'number of ways, but its essential features are a main continuous guard ring-4 to surround the rear end of the projectile in abutting relation with the rear edge of the ring 2, an auxiliary and split guard ring 5 to surround said projectile in contact with the front edge of the ring 2, and a split flexible collar 6 extending between and secured to the two rings 4 and 5.

In Figs. 2, 3 and 4, the ring 4 is shown of laminated construction, the laminations 7, with the exception of the outermost thereof, being in the form of split rings preferably formed of wood fiber with the grain of contacting rings running in opposite directions to gain strength. Alternate laminations 7 extend beyond the intervening laminations, as shown clearly in Figs. 3 and 4, so .that practically a tongue and groove joint is provided between the two ends of the ring 4, this joint being free to spring open as indicated in Fig. 4 when the outer lamination 8 is severed, if it should be desirable to remove the ring 4 in this manner. Said lamination 8 is the only one of the series which is continuous, the two ends thereof being riveted together by a rivet 9 while other rivets 10 extend through the several laminations to secure them together.

The rivets 10 also pass through one edge of the canvas or the like of which the collar 6 is constructed, said edge being interposed between certain of the laminations 7 of the guard ring 4 so that the latter projects both inwardly and outwardly from said collar to more or less guard the latter when the projectile is being rolled from one point to The sheet of material from which the collar 6 is formed, is passed around the auxiliary guard ring 5 and the free edge portion is secured by several rows-of stitching 11 to the inner face of the collar proper, so that an annular hem isprovided in which a circumferentially corrugated ring 12 of ,fiber or thelike is located to assist the collar guarding the packing ring 2 against injury.

The auxiliary guard ring 5 is by preference constructed of several layers or4 laminations of liber, the ends of which are in no way joined but are alinedsubstantially with the split 13 of collar A6, a strap 14 being provided for normally holding the ends of said v possible, both the strap 14 and the outermost lamination 8 of the guard ring 4 willfbe cut with a knife or other suitable tool, said lamination being severed adjacent the meetlng -ends of the otherlaminations 7 so that the ring 4 Will expand to thef position indicated in Fig. 4. The entire protector is 'thus free to be quickly withdrawn from the projectile.

In Figs. 5, 6, 7 and 8 the construction is substantially the same as that above described. In these figures, however, the outermost lamination 8 of the main guardv ring 4 is tapered at its ends so as to form a joint which will offer no obstruction to rolling the shell. In this type of the invention the material of which the collar 6 is formed is folded around the ring 4 as well as the auxiliary ring 5, 'the outer and inner portions of the folded material being stitched together at 11 so that an annular seam`is formed in which one of the rings or bands 12 is located.

Another point of dierence between this type of the device and that above described is that the strap 14 is eliminated in favor of a cord or small rope 14 passed around the collar 6 adj acentthe ring 5 with its ends tied together. This cord may be either untied or cut to permit the device to be removed, and .whenever required vthe lamination 8 may be severed so as to permit 'the entire' device to expand as'above described.

As a modification of the ring 4, it is shown in Fig. 9 as constructed of a main body 15 of wood, a number of laminations 7 secured in contact with the inner face of said ring, and an outer lamination 8 corresponding to the parts 8 and 8 above described. This form of ring may be preferable in some instances since it will not only be less expensive to manufacture but will be much stronger than rings constructed totally' of fiber.

When the improved devices are applied,

j the vmain and auxiliary rings 4 and 5 as well as the collars 6 and rings 12 effectively serve to guard the packing ring 2 against' injury and prevent the entrance of dust and grit into the grease in the grooves 3. The prounderstood that within the scope of the invention as claimed, numerous changes may be made without sacrificing the principal advantages. y

While I have shown and described the invention as being applied to the projectile from its rear end which of course is the most practical Way, since it may be done while the projectile is held by a grapple, it will be understood that the invention maybe applied from the tapered or front end of the projectile, or used in the position reverse from what is shown in the drawings.
