SHELL HANDLING DEVICE FOR TRENCH MORTARS Filed Dec. 1, 1942 Ell-wing Mklilcnxun Patented Sept. 9, 1947 V UNITED STATES SHELL HANDLING DEVICE FOR TRENCH MORTARS 14 Claims.
(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon,
This invention relates to a shell handling device, particularly to a device for loading trench mortar shell into the muzzle from a magazine.
It has been the custom in trench mortar firing to handle the shell individually, dropping a shell into the muzzle of the inclined barrel and relying upon gravity to accelerate the shell to a velocity suflicient to detonate the propellant charge on impact. Mortar firing based on this principle has a number of inherent disadvantages, the first of which is that the mortar cannot be operated below a predetermined minimum elevation. Another objection to this method of mortar firing is that it is slow and cumbersome.
It is an object of this invention to provide a device which may be attached to a trench mortar to permit firing of the mortar at any elevation, and to permit a rapid and uniform rate of firing. This is accomplished by a spring biased fork to grip the shell and force it into the muzzle at a given velocity in addition to its velocity due to gravity. The fork operates in a slotted guide which is secured to' the muzzle of the barrel and is aligned with it. An enlargement at the point of attachment permits withdrawal of the fork and release of the shell, which continues on to the bottom of the barrel where the propellant charge is detonated. A trig er holds the fork in shell receiving position. A magazine feeds shells to the guide and is provided with a stop to keep the shells away from the muzzle except when it is desired to feed a shell to the guide.
The specific nature of the invention as well as other objects and advantages thereof will clearly appear from a description of a preferred embodiment as shown in the accompanying drawings in which;
Fig. 1 of the drawings is a view in horizontal longitudinal section of a mortar muzzle with the invention attached.
Fig. 2 is a plan view of Fig. 1, showing details not disclosed in Fig. 1.
Fig. 3 is a view in elevation of the invention.
Fig. 4 is an end elevation view, with the trigger removed.
Fig. 5 is a side elevation detail view of the stop.
Referring now to the drawings in detail, 2 indicates the muzzle of a trench mortar or similar gun barrel to which the invention is shown attached. A guide 4 is provided with a collar 6 which fits snugly over the muzzle: end of the barrel, holding the guide in alignment with the barrel. The guide is slotted as at 8 to receive shell engaging means such as sliding block Iii carrying the forks or fingers I2 and provided with a handle M. Block I8 is movable in slot 8 axially of the barrel 2. Near the point of attachment of guide 4 t0 barrel 2, the guide is enlarged outward radially, as at I6, to permit withdrawal of shell engaging forks I2 from the shell as the latter is proj ected backward into the barrel. Shellsare shown in dot and dash lines at l8.
Block H] is preferably provided With spring mounted rollers 20' to facilitate its sliding along guide 4. A tension spring 22 biases block Hi toward the gun. Latch or trigger means 24 may be provided to retain block in forward against the bias of spring 22. A cord. 26 may be attached to the trigger to provide means for easy disengagement of-the trigger from theblock.
A magazine 28, is provided to hold shell [8 for feeding to guide 4. As can best be seen. in Fig. 4, guide 4 is substantially semi-circular in cross section, with its open face toward the right as seen in Fig. ,4; Magazine 28 is mounted to feed shells to this open face. A stop 30 is preferably provided to" keep shells from being moved into alignment with the mortar barrel. Stop 30 preferably consists of a substantially rectangular plate, as seen in Fig. 5, having an extending arm 32 adapted to be secured in non-rotating relation to one end'of a shaft 34. The other end of the shaft carries a pinion 36 which meshes with a rack 38. Rack 38 is preferably integral with a reciprocable rod 48, mounted in bearings 42 on the guided. Shaft is rotatable by the rack andpinion "in bearings 44 and 46. An upright rod 48 on rod is positioned to be engaged by handle l4. A spring 50 .on rod 40 may be provided to urge stop 30 downward when handle M is pulled out of engagement with rod 48.
To'insure proper alignment of each shell with the barrel, guide ext'ension'52=is provided in enlargement I6 of guide 4. Shells may be fed toward guide 4 from the magazine by gravity, for
' which purpose the magazine will be inclined, or
by a magazine spring, not shown.
Operation-With shells in the magazine, kept from the'barrel by stop 30, handle I 4 is pushed forward against the bias' of spring 22, moving rod 40 and rack 38 forward and raising stop 30 against the bias of spring 50. A shell rolls into position against guide 4 and is engaged by forks i2. If a latch 24 is provided, handle l4 and block I Bare held in the position shown in the drawings. When it is desired to fire the mortar, handle 14 and block are released for movement by spring 22. Where a latch or trigger is used, this involves pulling the trigger to release the block. Forks or fingers l2 thereupon carry the shell rearward into mortar barrel. As block 10 nears the muzzle, it is carried radially outward into ,enlargement i6, removing forks 12 :from engagement with the shell and permitting the latter to continue to the end of the barrel under the momentum imparted to it by spring 22.
Meanwhile, stop 30 has been dropped down :to hold the next shell away from the mortar muzzle.
If desired, the teeth at the inner end of rack 38 may be cut away, to permit stop 30 'to drop back into place after a shell has been released to the guide. In that case, a suitable ratchet or the like would be provided to permit pinion 136 to rotate loosely on the shaft for thefiring'stroke of the handle M and rack 38.
