FOLDER FOR DYNAMITE-SELL macmrns.

To all whom it may concern:

Be it known that 1, JOHN A. Jomrsrou, a citizen of the United States, residing at Emporium, in the county of Cameron and State of Pennsylvania, have invented certain new and useful Improvements in holders for Dynamite-Shell Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This inventionrelates to an improvement in the art of machines for forming paper shells or cartridges used for packing dynamite, and the invention consists more specifically in an attachment for folding or tucning in the ends of the shells or cartridges after the same have been wound or formed in the usual manner, said attachment being designed for use in connection with any of the well known machines used to wind or roll the shells or cartridges.

The object of the present invention is'the provision of a folder of this character which is of a simple. construction and which is wholly automatic in o eratio'n.

A further object of tlie invention is the provision of a folder of this character employing apluralityof folding members, either of which may be brought into position to operate upon the end of the tube to be folded, whereby said device may be used with equal success upon tubes of various sizes.

Other objects of the invention will be apparent from the detaileddescription hereinafter, when read in connection with the accompanying drawings forming a part hereof, wherein a preferable embodiment of my invention is shown, and wherein like characters of reference refer to similar'parts in the several views.

Referring now more particularly to the drawings, Figure 1 is a side elevation of a machine for forming shells for )acking dynamite,-with my improved attac unent secured thereto. Fig. 2 is a fragmentary front elevation of amachine for forming dynamite shells, with my attachment secured thereto. Figs. 3 and 4 are detail views illustrating two diflerent forms of folder wheels. Fig. 5 is a detail fragmentary view showing the folder wheel disclosed in Fig. 3 as making the fold on the end of the tube, and Fig. 6 is an end view of a tube alter the same has been folded but before the folds have been tucked in.

in the drawings, A designates a mandrel of a machine for forming paper shells used for pacln'ng dynamite which is designed to be Specification of lietters Patent.

driven in any suitable manner and u on.

which the tube may be wound or lorme by any of thewell known methods. Secured in the lower part of the frame of the machine and positioned at one side of the mandrel A. and extending parallel therewith, is a shaft B upon which is secured a lar e gear wheel B. The shaft B is ada ted to e driven by the driving means whic actuates the mandrel A and is connected thereto by gearing which may be of any suitable construction and which, as it forms no part of the present in vention, has for the sake of olearness been omitted from the drawings.

C designates a fixed shaft. which is suported in any suitable manner. from the rame of the machine and whch is positioned above the shaft B and exten s arallel thereto. Mounted upon the shaft O so as to rotate freely thereon is a small gear wheel D which meshes with the gear Wheel B socured to the shaft B, and a somewhat larger gear wheel D which is also loosely mounted on the shaft C and is connected in any suitable manner with the small gear wheel D so as to rotate therewith? Loosely fulcrumed on the shaft C at one side of the ear wheel D mounted thereon is a lever E, t e, lower end of which extends into proximity to the shaft B and the upper end of which is adapted to be swu in a path across the outer end of the man rel A. Journaled in the end of the lever E is a shaft F to which is secured a car wheel F, which'is cared to the ear w eel l3 mounted upon t e fixed shaft through the medium of an idle ear wheel ll, journaled on the lever E an meshing with the ear WheelD, from which construction it will e a parent that the shaft F will be constant y rotated regardless of the position to which the lever E may be moved on its fulcrum. Rigidly connected in any suitable manner to the end of the shaft F adjacent the outer end of the mandrel A is a folder tube. In the form of the invention dis closed in. the accompanying drawin the folder is shown as provided with five ngers, as this number has been found to work successfully with tubes of all sizes, but it is obvious that the number of fingers may be varied, if desired, without departing from the spirit of the invention. n using the folder in connection with shells of a ve small diameter, it has been found that if the form of folderheretofore described is used, the first fold or tuckis apt to spring out before the shell is engaged by the next succeeding finger to make the second tuck or fold, and hence it has been found necessa to provide a folder wheel of a special form fbr tubes of such a size. H designates a folder wheel designed for this urpo'se. The wheel G is removably secure in any suitable manner to one end of the shaft F so that it may be readily removed and the position of the shaft reversed according as it is desired to use either the wheel G or the wheel H, the wheel G being used upon the larger and the wheel H upon the smaller tubes. It is obvious that the same result may be obtained by removably securing the 'wheel H or both the wheels G and H to the shaft. The wheel H is rovided with five'fingers it, which are simi er in construction and location to the fingers g of the folder wheel G heretofore described, with the exception of the first finger, which is provided adjacent the rear portion of the outer edge thereof with a sucplplemental finger h, which projects outwar g be 0nd the outer edge of the finger of whic it orms a part. In the operation of the device, when this form of folder wheel is employed,

the supplemental finger it will engage the projecting end of the paper shell or cartridge and form a supplemental fold therein which will prevent the fold, formed by the first finger h from pushing out before the second fin er of the folder engages the "meeting on of the shell to form the secon fo d, the remaining folds being formed successively by the remaining fingers h.

The folder wheels G and H are each. provided with collars on the inner faces thereof,

which serve to space the same res ectively eel F and the s1 e of the from the gear w lever E. The collar on the inner face of the folder wheel G. is however, considerably wider than the collar on the folder wheel H, whichfthrows the folder wheel G in nearer the end of the mandrel when the same is used than the osition occu ied b the folder wheel H w on that wheel is used This construction is essential as deeper folds must be made on the ends of the large tubes in connection with which the folder G is employed, than on the ends of the smaller tubes in connection with which the folder H is employed.

The gearin between the driving means for the mandrel H and the .folder wheels G and H is of such a construction that the relative speeds of rotation of the mandrel and folder wheel are such that by the time the mandrel has made one complete revolution after the proper folder wheel has been thrown into operative position, all of the fingers of'the folder wheel will have engaged the projectiw end of the shell on, the mandrel and forme the re er number of folds therein, after whic t e folder wheel will be thrown to inoperative position and the folds tucked in, as'will be hereinafter more particularly set forth.

The desired folder wheel is normally held v in an inoperative position by means of a spring I which connects the .e t e fulcrum thereof 1th a suitable portion of the frame of the machine, but is adapted to be periodically thrown into operative position by an arm or cam B, which is carried by the shaft B and is adapted during the rotation of said shaft to engage the lower end of the lever E and move the same outwardly. From this construction, obviously, as long as the cam or arm ll remains in engagement with the lower end of the lever, it is apparent that the folder wheel will beheld in operative position and that as soon as the cam or arm rides off the end of the lever the folder wheel will be withdrawn from operative position by means of the spring I. The gearing which connects the driving means of the mandrel A and the shaft B is adapted to be of such a construction that the folder wheel will not be thrown into operative position until the shell or cartridge has been completed -u on the mandrel and the construe tion of tlie lower end of the lever E and the cam or arm B is such that the folder will be held in o erative position just long enough to form all of the folds in the end of theshell.

K is actuated to engage t e folds previously made by the folder wheel and tuck the same l into the end of the shell or tube, after which 1 the arm is lowered and the shell or tube re 'moved from the mandrel by any suitable means. Any suitable means may be provided for operating the arm K, but I prefer to provide the same adjacent its fulcrum wit tends a link 11: which may be actuated in any suitable manner by the same means which imparts-rotation to the mandrel A. if the arm K is actuated in this manner, it will be obvious that the construction employed must be of such a nature that the movement of the arm K must be so timed as to occur imme diately after the folder has been moved to an inoperative )osition. The in It is preferver E above Pivotally-mounted in the forward part, of

u an offset it", from which pivotally ere i upper end a pin k which is provided. with a ably adjusts ly secured in t e upper end of the arm K, a preferred construction being crests 0 shown in sccoznpsnyin drewing', in

which, the pin is thresded one is held in soy desired position by e not positioned on opp-osite sides of the error.
