PIVOT-STAND FOR WHEELED GUN-CARRIAGES.
Application filed April 26, 1913.
To all whom it may concern Be it known that we, WALTER HniLE- MANN, residing at 22 Otmarstrasse, Essenon-the-Ruhr, Germany, and HEINRICH KANONENBERG, residing at 99 Rellinghauserstrasse, Essen-on-the-Buhr, Germany, both subjects of the Emperor oi Germany, have invented a certain new and useful Improve ment in Pivot-Stands for lVheeled Gun- Carriages, of which the following is a speciiication.
The subject matter of the present invention resides in a pivot stand for wheeled gun carriages, which is constructed so that it does not need to be tilted, when the height of the trail end changes during swinging around of the gun carriage.
In the accompanying drawing is shown one embodiment oi' the invention and Figure 1 shows a side elevation of the pivot stand together with a. gun carriage, Fig. 2 a top plan view ot' the pivot stand, and Fig. 3 a section of the pivot stand along lines 3-3 of Fig. l seen from the left.
The pivot stand has a pedestal A and an upper portion, which consists of two parts B and B1, to be described later. The pedestal A may be let into the ground and is provided with a bearing al for the pivot proper b2 of the part B. Between this part and the pedestal A is inserted a ball bearing c2. Two transverse bearings b3 see Figs. l and 3 are provided on the part B1 for the axle-tree G of the gun carriage. The bearings ?)3 are open on the side nearest the muzzle of the gun, see Fig. l, and may be closed by caps b4. The height of the pivot stand has been selected so that the wheels D of the gun carriage do not touch the ground when the axle-tree Gr rests in the bearings b3 b4.
ring R is revolubly but nondisplace ably mounted in an annular groove a3 of the pedestal A, which ring is composed of two parts. On this ring are provided two trunnions r1, situated diametrically opposite each other and on which a fork E is mounted to oscillate,vand which fork carries a sleeve with an eyelet e1. This eyelet is intended to engage with a hook f1, on the trail body F of the gun carriage. The fork E is provided directly transferring to recoil pull caused by the preventing the tilting of the pedestal A the shot, and thereby Specification of Letters Patent.
- Patented Dec. 8, 1914.
Serial No. 763,845.
the pivot stand under the action of the recoil pull.
The part B1 oi' the pivot stand is carried in the part B, by means of two flanges If which engage under iianges ZJ of the part B, see for instance Fig. 3, in such a manner that it may be displaced relative to the part vagainst rapidly moving targets (for instance air ships) it is brought upon' thc pi vot stand. For this purpose the pedestal A is let into the ground and the gun carriage is rolled up on wedges, see Fig. l, which are laid along the pedestal until the axle-tree G rests in the bearings b3. The bearings 3 are thereupon closed by means of the caps 224, the key bolt C taken out, and the eyelet c? of the fork E is brought into engagement with the hook f1 ot' the trail body. The gun carriage may thereupon be swung easily, around the axis of the pivot b2, by means of a training gear (not shown in the drawing), which is inserted between the pedestal`A and the part B; or by means of a hand spike the groove a3.
Should the trail end during the training of the gun carriage be lifted by means of the hand spike and then again laid down on the ground, or should the trail slide Ion uneven ground during the training of the gun carriage the fork E will then rock around the axis of the trunnions r1 and the axle-tree G will oscillate in the bearings b3 64. A displacement of the part B1 of the pivot stand relative tothe part B will simultaneously take place without tilting the pivot stand. i
The described displacement is caused by the raising and lowering of the point f2 of the trail body where the fork E is engaged by the hook f1 and this point travels in a circular arc described :from the axis of the trunnions r1, the distance of this point f2 from the aXle-tree remaining constant.
As the pivot stand in consequence of the described construction does not need to be tilted during the training of the gun carriage, this training of the gun carriage may take place With the least possible power consumption. The described arrangement moreover possesses the advantage that the trail end of the gun carriage, even on rough ground, can rest on the ground in any position of the gun carriage.
We claim l. A pivot stand for a Wheeled gun carriage having a trail comprising a pedestal, a pivotmounted to revolve on said pedestal,
a cradle constructed to engage with and supcradle constructed to engage With and support the forward end of the gun carriage;
said cradle and pivot having interengaging sliding members permitting displacement of the cradle relative to said pivot in the longitudinal direction of the gun carriage.
3. A pivot stand for a Wheeled gun carriage having a trail and an axle-tree, comprising a pedestal, a pivot mounted to revolve in said pedestal, a cradle mounted on 'u said pivot, a pair of transverse bearings on "fas F -g said cradle 'adapted to receivethe axle-tree ofthe carriage, said cradle being adapted to 'slide on said pivot in the longitudinal direction of the gun. i
4. A pivot stand for a Wheeled gun carria-ge having a trail and an axle-tree; comprising a pedestal, a pvot mounted to revolve in said pedestal, a pair of transverse bearings slidably mounted on said pivot and adapted to receive the axle-tree of the gun carriage; a trunnion ring mounted to revolve in a horizontal groove in said pedestal, a pair of diametrically opposite trunnions on said ring, a fork engaging said trunnion to oscillate thereon; an eyelet on said fork and a hook on the trail for engaging said eyelet; whereby the gun carriage may be swung in a horizontal plane around the aXis of said pivot.
5. A pivot stand for Wheeled gun carriages having a trail and an axle-tree, comprising a pedestal, a pivot mounted to revolve in said pedestal, a cradle mounted on said pivot to slide thereon in the longitudinal direction of the gun, a pair of transverse bearings on said cradle adapted to receive the axle-tree of the gun carriage; a trunnion ring mounted to revolve in a horizontal groove in said pedestal, a pair of diametrically opposite trunnions on said ring, a fork engaging said trunnions to oscillate thereon, and an eyelet on said fork, a hook on the trail for engaging said eyelet; whereby on raising the trail end from the ground the axle-tree Will rook vin the cradle bearings and the cradle slide on the pedestal.
