T0 all whom t may concern,.-

Be it known that I, ALFRED A. THRESHER, of Dayton, in the county of Montgomery, State of Ohio, have invented certain new and useful Improvements in Telescopic Rammers for Ordnance; and I do hereby declare the ,following -to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to mechanically-operated rammers for ordnance, and more particularly to that class of rammers formed of telescopic sections and adapted to be located on a fixed mount in rear of the gun. This class of devices is primarily designed for use in confined areas-as, for instance, a turret of a ship. Hence compactness combined with great power are prime essentials; and it is one of the objects of the present invention to provide a compact and self-contained structure embodying the rammer mechanism proper, together with the motor for operating the same.

A further object of the invention is to provide an improved means for securing the motor in the rammer-mount, which will permit of the motor beinfI constructed as an entity, which may be readily placed in position and secured in its pro er position with relation to the rammer mec anism or removed therefrom should occasion require, and ,at the same time the arrangement will'be such that the rammer with its motor will occupy practically no greater space than the rammer mechanism and its mount.

Referring to the accompanying drawings, Figure l is a side elevation, with portions broken away and in section, of a rammer embodying the present invention. Fig. 2 is a vertical section in a lane at right angles to Fig. l and-centrally o the motor.

Like letters of reference in both the figures indicate the same parts.

The rammer mechanism proper or the telescopic sections, together with themechanism directly connected therewith for extending and retracting the same, is similar to that now in common use and "is substantially as described in United States Patent N o. 627,404, granted to T. C. Fenton June 20, 1899. Specic description of the same is therefore unnecessary; but it will be understood that the telescopic sections A are operated by the shaft-B through the medium of the rack and pinion O and hauling-in rope D. The said telescopic sections, together'with their operating mechanism, are carried by a mount or frame F, adapted' to be located permanently in rear and in line with the gun when the latter is in loading position, and in the present invention said mount contains the motor mechanism, as well as the manually-o erated mechanism, for imparting rotation to t e shaft B. Said shaft B is connected at one end with the usual train of gearing G for manual operation of the rammer, and at the opposite end or on the opposite side of the mount it is provided with a relatively large sprocketwheel H, around which a drive chain H passes. Drive-chain H extends back to and around a small sprocket-wheel K, located directly on the motor-shaft L.

The motor is an electric motor which is self-contained and is located in the rammermount directly beneath the telescopic sections or in such position that its armature is in the mount, while its shaft projects at the sides. In its construction the motor embodies a center or field ring M having an external fiange m and inclosing heads N and N in which the shaft L is journaled. The fieldring adjacent the flange m and the head N are formed to fit openings in the opposite side walls of the rammer-mount, while the flange m fits against the outer side of one of sald walls, all as shown clearly in Fig. 2, the whole motor being rmly held in place by bolts O passing through the flange m and both sides of the mount. The annular flange thus constitutes the means for locating and securing the motor in place, although, if desired, head N may also be secured to the mount by tiepieces P, held by the bolts O, against the side of the mount and by boltso against the outer face of the head.

The motor illustrated is of the inclosed type, and the head N is as a consequence dished outwardly to accommodate the shaftbearing Q and commutator R within it. To permit access to the commutator and armature, the head N may be provided with a door S.

Both of the shaft-bearings, it will be seen, are on the inside of the heads. Thus there are no projecting parts liable to be injured and throw the motor out of action. The motor serves to brace and strengthen the rammermount and occupies a space .heretofore notl preferably IOO IIO

utilized for any purpose, a consideration of much importance in the restricted areas where apparatus of this character is used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a telescopic rammer for ordnance, the combination with the telescopic sections, mount in which they are supported having an opening extending transversely therethrough below the sections and gearing for operating the sections, of an electric motor for said gearing located in said transverse opening, a flange on the motor and bolts uniting the flange and mount 3 substantially as described.

2. In a telescopic rammer for ordnance,the'

combination with the telescopic sections, the mount in which they are carried having transverse openings in its sidewalls below the sections and gearing for operating the sections, of an electric motor for said gearing having its frame extending through and fitting said openings and a flange seating -against one of said side walls and connected thereto 3 substantially as described.

3. In a telescopic ramrner for ordnance,-the combination with the telescopic sections, the mount in which they are carried having transverse openings in its side walls below the sections and gearing for operating the sections, of an electric motor for said gearing having a frame extending into the mount through one of said openin vs and inclosing heads for said frame locate at each side of the mount `and having the bearings for the motor-shaft on their inner sides; substantially as described.

4. In a telescopic rammer for ordnance,the combination with the telescopic sections, mount in which they are carried having openings in its side walls below the sections and gearing for operating the sections, of the motor for said gearing having its frame fitting the openings in the side walls of the mount, the flan e fitting against one of said walls and the olts passin through said flange and walls; substantial y as described.

5. In a telescopic rarnrner for ordnance,the combination with the telescopic sections, mount in which they are supported having a transverse opening therethrough below the sections, of an electric motor for operating said sections having a flanged field-'ring ttin in said opening bolts uniting the flange an mount `and heads for closing the ends of said ring having internal bearings for the motorshaft; substantially as described.
