Specification of Letters Patent.
Patented Sept. 12, 1916.
Application filed March 3,' 1916. Serial No. 81,905.
To all whom it may concern Be it known that I, STANISLAS MALo, a subject of the King of Great Britain, residing at Quebec, in the Province of Quebec, and Dominion of Canada, have invented certain new and useful Improvements in Shell- Making Machines;-and I do hereby declare the following to be a full clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to a shell making machine.
The object of the present invention is to provide a simple, practical and etlicient construction for shell making machine adapted to enable a punch of the requisite strength to be employed and equipped with means for properly positioning shells with relation to the punch and the die adapted to be automatically moved out of the way when a thickened or reinforced portion of the die moves inwardly into the bottom of the hopper or shell receptacle and capable when the punch is withdrawn of automatically moving upwardly to its initial supporting position for holding the next shell in position to be operated on by the punch.
A further object of the invention is to provide a die of increased durability and enable the cost of the upkeep of the machine to be materially decreased.
\Vith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the drawings Figure 1 is a side elevation partly in section of a portion of a shell making machine embodying the invention, Fig. 2 is a vertical sectional view of the same taken substantially on the line 22 of Fig. 1, and illustrating the punch and showing a portion of the coacting die, Fig. 3 is a sectional view of the die.
Like numerals of reference designate corresponding parts in the several figures of the drawings.
In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the shell making machine comprises 1n its construction a hopper 1 adapted to receive shell'blanks 2 and suptical movable support 5 having a tapered shell receiving recess 6 located at an opening 7 in the bottom of the hopper and constituting a bottom for the same and adapted to support the lowermost shell blank in proper position to be operated on by a punch 8 and also in proper position with relation to a die 9 into which the shell blank is forced by the punch to properly shape the shell. In order to provide a punch of the requisite strength the stock 10 is thick ened and is tapered at 11 adjacent to the shell forming cylindrical portions 12. The die 9 is positioned at the-side of the hopper as clearly illustrated in Fig. 2 of the drawings and in order to enable the tapered and thickened portion of the stock to move across the bottom of the hopper over the shell support 5 the latter is vertically movable in the chamber or recess and is guided and limited in its movement by a horizontal pin 1% extending across the recess and passing through a slot 13 in the shell support 5. The opposite walls of the chamber or recess d are vertical and the support 5 has smooth vertical side faces to fit the said walls. The shell support 5 is yieldably maintained normally in an elevated position by spaced coiled springs 15 arranged in vertical openings 16 of the body 3 and mounted upon adjusting screws 17 arranged in threaded counter bores 18 of the said interfering with the proper operation of the m chanism- The die comprises in its construction three members, namely a holder 19 and sections 20 and 21. The holder which is provided with a flange 22 has a tapered opening 23 and the section 21 is exteriorly tapered to fit the opening 23. The front section 20 is provided with a flange 24 which fits against the flange of the holder. This construction enables the section 21 to be renewed without discarding the entire die.
The die and the other parts may be mounted in any desired manner and any suitable means may be employed for actuating the punch and as the invention resides in the construction of the punch, the die and the means for feeding the shells and yieldably supporting the same, illustration of such supporting and actuating means is believed to be unnecessary.
The front and rear sections are provided with cylindrical bores or openings 25 and 26" and the bore or opening 25 of the front section is enlarged and inwardly tapered at 27 to receive the tapered portion of the punch. The flaring portion of the bore or opening of the die forms an enlarged mouth and provides for an easy entrance of the shell and the centering of the same.
Material advantage and economy result from the particular construction of the die, which, should it become worn or broken may be removed and set aside until a number of dies require regrinding so that the same may be reground with one setting of a machine. This will result in the dies being of a uniform size with. the cylindrical portions of the opening of the same length. The regrinding of the dies will shorten the tapered portion of the bore or opening but the reduction in the length of the tapered portion will not interfere with the operation of the die. A great saving in both labor and mate-- rial results from the use of the particular construction of the die.
W hat is claimed is 1. A shell making machine of the class described including a hopper, a die located adjacent to the hopper, a yieldably mounted shell supporting device arranged to hold a shell in proper position with relation to the die and a punch having an enlarged portion adapted to move across the yieldable support and force the same from its normal supporting position.
2. A shell making machine of the class described including a hopper, a die located adjacent to the hopper, a yieldably mounted shell supporting device arranged to hold a shell in proper position with relation to the die and a punch having a thickened stock provided with a tapered portion and adapted to move over the yieldable support which is forced out of its normal position by the said punch.
3. A shell making machine of the class described including a hopper provided in its bottom with an opening, a vertically movable support provided in its upper face with ashell receiving recess, yieldable means located beneath the support and normally maintaining the same in a supporting position and a punch having an enlarged stock provided with a tapered portion arranged to move the support and force the same downwardly.
4. A shell making machine of the class described including a hopper provided in its bottom with an opening, a vertically movable support provided in its upper face with a shell receiving recess, spaced springs located beneath the support and normally maintaining the same in an elevated supporting position, adjusting screws engaging the lower ends of the springs and a punch having an enlarged portion arranged to move over the support and adapted to force the same downwardly.
5. A shell making machine of the class described including a hopper provided in its bottom with an opening, a. vertically movable support provided in its upper face with a shell receiving recess, said support being also provided with a horizontal slot, a fixed pin mounted in the slot for limiting the movement of the support, yieldable means for urging the support upwardly and a punch having an enlarged portion arranged to move over the support and adapted to force the same downwardly.
6. A shell making machine of the class described including a die, comprising a, holder having a tapered opening, and front and rear sections, the rear die section being tapered and fitted in the tapered opening of the holder and the front die sections being fitted against the said holder at the front thereof.
7. A shell making machine of the class described including a die, comprising a holder having a tapered opening, and front and rear sections, the rear die section being tapered and fitted in the tapered opening of the holder, said holder and front sections being provided with abutting laterally projecting flanges.
In testimony whereof I affiX my signature in presence of two witnesses.
