This up- The apparatus comprises a frame 1 in setting tool 61, constituted by a simple rewhich is provided a clamping screw 41 havcess, is actuated in its rotary movements by the train of gearing 61 127 the wheel 127 being fixed on the end '127 of the driving shaft.

The double socket 125 presents a web 125 engaged between the flanges of the frame 1 and is removably connected to the frame e. g. by screws.

A. removable abutment 18 having a thrust collar 97 is engaged by a centering plug 98 in the upsetting socket 60.

The carriage 19 consists of two elements, a socket 140 and a carriage body 141.

The socket 140 is formed as a nut and is screwed onto the threaded portion of the driving screw 12?. It is of rectangular cross section (Fig. 3) which prevents it turning relative to the frame 1, whilst permitting it to slide on the frame. Two vertical guides 142 142 are carried by the socket 140.

The body of the carriage 141 has a recess 37 for the engagement of the flange of the head of a sporting cartridge case when of the appropriate calibre, an aperture for the ejection of the detonated cap and for the en gagement of a new cap and a truncated conical seating 19 to receive the flange of the sporting cartridge case durlng the upsetting.

The body of the carriage 141 has two vertical slides 143 1 13 (Fig. 1) by means of which this body engages on the vertical guides 1 12 1 12 of the-guide socket 140.

This arrangement enables the instant removal of the body of the carriage body 1411 and its replacement by another carriage body corresponding to the calibre of the cartridges which are to be operated on.

The socket 140 is engaged by a web 19 (Fig. between the flanges of the frame 1 and rests by means of a machined surface 19 011 the machined surface 1 of the frame, which ensures "the proper guidance of the carriage during sliding.

The above described apparatus operates in the following manner. In order to recondition a used sporting cartridge 55 (Fig. 5), the flange 50 of the head of the cartridge case is engaged in the recess 37 0f the car riage 19 (Fig.

The crank 9 is then operated, turning the screw 12? in a direction so that the carriage 19 is displaced in the direction 130 (Fig. 1) relatively to the frame.

The paper tube 55, enters the free space left between the mandrel 5 and the socket 3 and is guided during this movement by the conical surface 12 of the mandrel 5.

' The mandrelmoreover is turned constantly about its axis by the gearing 127 128 and 5 and thus ensures the exact calibration of the sporting cartridge case -55 and the smoothing of the surfaces of such case.

At the termination of the above movement, themechanism actuating the mandrel 5 is cut out by sliding the intermediate wheel 128 by means ofits slot on the intermediate spindle 128 which enables this wheel to be separated from the spur wheels 127 5 The rotation of the mandrel 5 is thus interrupted.

However, the carriage 19 continues its displacement in the direction 130 (Fig. 1), so that the detonated cap 56 encounters the ejecting nipple 13, (Fig. 5) the border of the cap engaging in the neck 14.

The cap 56 is thus ejected through the aperture 25 and drops outside the carriage 19. The rounded shape of the neck 14 prevents the expansion of the cap 56 during the preceding thrust and facilitates its extraction.

Moreover, there can be no fear. of the upsetting of the wall of the cap 56, under the action of the mandrel 5, the; mandrel being unclutched and ceasing all rotary movement, as has been explained above. For these various reasons the border of the cap 56 remains smooth. The cap is therefore easily ejected from the head 86.

At the termination of the preceding movement the head 86 comes to bear against the annular face 85 of the mandrel 5, which ensures the flattening ofthehead, after ejection of the cap 56.

A new cap can then be inserte into the cartridge. To effect this, the cap 'is placed in the aperture 25 ofthe carriage 19, the cartridge '55, re-conditioned and dispossessed of its detonating cap, being mounted by means of itsflange 56 in the recess 37 of the carriage (Fig. '5). The crank 9 is then'actuate'd so as to displace the carriage 19 in the opposite direction i. e. reverse to arrow 130, the carriage body taking with it the cartridge 55 and the new cap 60 This cap therefore will encounter the abutment 18 which efiects the insertion of the cap into the head 86, and the cartridge is thus capped.

The apparatus moreover avoids any error 7 in capping, because if the cap 60 is not com pletely inserted in the head 86, it is impossible to disengage the cartridge from the carriage 19, owing to the cap remaining engaged in the aperture 25. In that case a re newed operation of inserting the cap is effected.

The re-capped sporting cartridge case is removed from the carriage 19 and is charged with powder and shot in the ordinary manner. It is then necessary to upset the cartridge case. To eiiect this, the cartridge is engaged by its flange in the truncated conical seating 19 of the carriage, and the capping-abutment 18 isremoved from the .upsetting socket 60, which thus becomes open ended (Fig. 7 The crank9 is -then turned in a direction so that the carriage 19 moves in a direction opposite to arrow 130. The

cartridge case enters the upsetting socket 60. The upsetting tool 61 is at these-me time rotated by means ofthe train o f gearing 127,

61 and thus effects the upsetting of the cartridge.

gans (60, 61 are mounted so as to be instantly removable. A sportsman can therefore use one and the same apparatus, employing several different sets of these organs, each set corresponding to a particular calibre of cartridge (12, 16, etc.) the same apparatus thus enables the re-conditioning of cartridges of various calibres.

It should also be noted that the re-conditioning organs, the carriage and upsetting organs being mounted on one and the same driving shaft, the actuation of the apparatus is efiected by one hand, the other hand of the operator remaining constantly free.

Moreover the carriage 19 being mounted on the same shaft 127 as the re-conditioning and upsetting organs, such carriage is constantly centered with precision relative to those two organs.

The apparatus forming the subject of the invention can also be used for the calibration of deformed new cartridge cases. For this it suifices to mount the new and capped cartridge case in the carriage 19, to remove the uncapping nipple 13 from the mandrel 5 and to turn afresh such mandrel by means of the crank 9. Thus the calibration of the car tridge is effected, without risking any shock to the new cap, this cap being actually located opposite the aperture 25 of the carriage, and the nipple 13 of the mandrel 5 being removed.
