adapted to be inserted in the production line for projectiles to be armed with nose fuses, for use in cutting a staking notch in the nose of a projectile.

The speciiic nature of the invention as well as other objects and advantages thereof will clearly appear from a description of a preferred embodimentas shown in the accompanying drawing in which:

Fig. 1 is a plan view of the support of this invention disposed in operative relation to a staking notch cutter and showing a projectile on the work table movable in the direction of the arrow' toward the support;

Fig. 2 is a view partially in elevation and par tially in section taken on the line 2-2 of Fig. 1 looking in the direction of the arrows.

Referring now to the drawing by characters oi' reference, there is shown in Fig. 1 a work table Ill arranged in the production line for projectiles II and adapted to receive the projectiles II in any convenient manner after certain prior operations thereon in the course of production.

The table I0 may be suitably inclined to provide for movement of the projectiles from left to right, as viewed in Fig. 1, under the influence of gravity or otherwise arranged to facilitate movement of the projectiles as desired.

A plurality of rollers I2 are journaled in the table I0 adjacent its rightmost end as viewed in Fig. 1, with their axes disposed in parallelism with the direction of normal travel of the projectiles upon the table. Each of the rollers I2 is so journaled in the table IIJ that its upper surface projects a sufficient distance above the surface of the table III as to support a projectile II resting on the rollers with its rotating band or bands I3 clear of the table in order to prevent injury thereto in movement transversely of the table. To further ensure preventing injury to the rotating bands I3 of the projectiles the rollers I2 are suitably covered with any desirable material softer than the material of the rotating bands.

In alignment with the rollers I2 and disposed on the same side of table Ill as the noses I4 of the projectiles I I is arranged a conveyor roller frame comprising spaced parallel side plates I5 secured to the bed frame of the staking notch cutter I8 or to any other suitable support, and having a plurality of hardened rollers I6 journaled therebetween in such manner as to receive a projectile II from the rollers I2 and con- Vey it in line forwardly. Movement of a projectile I I forwardly on the rollers I6 is limited by an adjustable stop plunger I'I, suitably secured to the bed frame of the staking notch cutter or other support, which engages the nose bore of the projectile to limit the forward movement of the projectile on the rollers I6. In the instance illustrated two hardened rollers I6 are employed, which are so arranged as to engage the bourrelet and body of a projectile, respectively, in lsuch manner as to support the latter with its axis in a horizontal plane. Moreover, the adjustable stop Il is so positioned relative to the rollers IB as to prevent forward movement of a projectile II thereonto an extent that will permit engagement of the rotating bands I3 with the rearmost of the hardened rollers I6. The stop I'I also, in addition to limiting forward movement of a projectile on the rollers I6, serves to rigidly support the nose of the projectile during the staking notch cutting operation to next be described.

The staking notch cutter I8 supported by its bed frame is arranged to cut a staking notch in the nose of the projectile in a plane of its axis as the projectile is urged forwardly on the rollers I6 against the cutter and adjustable stop Il.

After a staking notch is cut in the nose of the projectile it is withdrawn from the hardened rollers I5 to a position upon the rollers I2 With its rotating bands I3 clear of the rear end of the work table IIJ and transferred by means of a table, which may be a continuation of work table ID, to another work station.

Having now described a present preferred embodiment of the invention I claim:

l. In a support for projectiles in combination, a work table arranged for movement of a projectile thereon transversely of its axis, a plurality of rollers journaled in the table with their axes disposed in parallelism with the direction of said transverse movement adapted to receive and convey a projectiie longitudinally of its axis, a plurality of conveyor rollers disposed on one side of said work table in alignment with said work table rollers adapted to receive a projectile from the latter for continued axial movement, a stop supporting member provided forwardly of said conveyor rollers in alignment therewith, and a longitudinally movable stop mounted on said stop supporting member arranged to be engaged by and support the nose of said projectile for limiting axial movement thereof on said conveyor rollers. y t

2. In a supportrfor projectiles in combination, a work table arranged for movement of a projectile thereon transversely of its axis with its rotating bands unsupported by the table, a plurality of rollers covered with a material softer than said rotating bands journaled in the table with their axes disposed in parallelism with the direction of said transverse movement adapted to receive and convey a projectile longitudinally of its axis, a pair of hardened rollers disposed on one side of said work table in alignment with. said work table rollers adapted to receive a projectile from the latter for continued axial movement, a stop supporting member provided forwardly of said conveyor rollers in alignment therewith, and a longitudinally movable stop mounted on said stop supporting member arranged to be engaged by and support the nose of said projectile to limit its axial movement upon the hardened rollers to a position where the rotating bands of the projectile do not engage the rollers.

3. In a support for projectiles in combination,

a work table arranged for movement of a projectile thereon -transversely of its axis with its rotating bands unsupported by the table, a plurality of rollers covered with a material softer than said rotating bands journaled in the table with their axes disposed in parallelism with the direction of said transverse Ymovement and their upper surfaces projecting above the upper surface of the work table a distance greater than the depth of the exposed parts of said rotating bands adapted to receive and convey a projectile longitudinally of its axis, a pair of hardened rollers disposed on one side of said work table in alignment with said work table rollers adapted to receive a projectile from the latter for continued axial movement, said hardened rollers be-V ing arranged to support the projectile with its axis in a horizontal plane, a stop supporting member provided forwardly of said conveyor rollers in alignment therewith, and a longitudinally adjustable stop mounted on said stop supporting member arranged to be engaged by and support the nose of said projectile to limit its axial movement upon the hardened rollers to a position where the latter only engage the bourrelet and body of the projectile forwardly of the rotating bands, respectively.
