EDGE-FOLDING IVZACHINE POCKET-BOOK BODIES.

Application filed October 16, 1916.

To alt HVILONL it wmg/ concern:

Be it known that I, WALTER C. EIorIEL- Bnnann, a citizen of the United States, and resident of lVestBend, in the county of iVashington and State of Wisconsin, have invented certain new and useful Improvements in Edge-Folding Machines for Pocket-Book Bodies; and I do hereby declare that the following is a full, clear, and exact description thereof.

My present invention relates to new and useful improvements in machines for folding the edges of the bodies of pocket books, particularly that class which have hinged metal jaw pieces secured to the edges of the bod die of the principal objects of the inven tion is to provide a very simply constructed machine whose operation will be very efficient and speedy.

An additional object is to provide a machine, the parts of which are so arranged that the edges of the piece of work naterial being operated upon will be simultaneously forced inwardly into the proper position and pressed between a heating member and a movable body member normally supporting the material.

A still further object is to provide a novel arrangement of bending plates and means for quickly actuating the same.

With these and many other objects in view, the invention resides in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed.

In the drawings:

on the line '5-5 of Fig. 1 through the pressing and heating member of the machine.

Figs. 6 and 7 and 8 are partly diagrammatic views showing successive steps in the folding and pressing operation of the machine, the operation being carried out with out the use of the die blocks 9 in order to simplify the illustration.

Fig. 9 is a transverse sectional view through the pocket book body as folded by the machine.

Fig. 10 is a plan view of the body as folded.

Referring now more particularly to the accompanying drawings, the embodiment of my machine therein shown includes a bed plate 5 which is held in spaced relation above a table support 6 by depending edge wall portions 7 which serve to house a portion of the folding mechanism. The intermediate portion of the bed plate is downwardly offset to provide a recess 8 for receiving the pocket book bodies to be folded. To adapt the recess for operative reception of various sizes of pocket books, said recess has detachably seated therein the die block 9 the top face of which is flush with the top face of the bed block, this block being provided with a recess 10 the area of which corresponds to the area of the desired size of pocket book bodies when folded.

The edge bending means comprises a pair of flat side bending plates 11 slidable on the bed plate 5 and disposed forwardly and rearwardly of the die block recess 10 and adapted for movement longitudinally of the axis of the machine, these plates being adapted to bend the side edge portions of the pocket book body and being held for proper sliding movement by upstanding guide flanges 12 at the side edges of the body plate 5 and slidably disposed over the end portions of the side bending plates 11 are end bending plates 13 adapted for movement inwardly of the end portions of the recess to bend the ends of the pocket book body, the plates 11 being provided between the plates 13 at their inner portions with upstanding en- I 13 whereby simultaneous inward movement of all the plates is permitted.

tions of the plates 11 and 13 are provided with slots 17 and 16 respectively, extending at angles to the slots 15 and ,intersectlng said slots. Through the intersection of each set of slots 15, 16, and 17 is passed a bolt 18 projecting below the top wall 5 and hav ng mounted on its lower end a link 19 having its inner end pivoted to and extending tangentially from the peripheral portion of a plate 20 which'is journaled on a bearing sleeve 21 carried centrally by the off set portion of the bed plate 5. Thus upon rotation of the plate 20 the bolts 18 will be simultaneously drawn inwardly and will exert a cam action on the edges of the slots 16 and 17 of the bending plates to simultaneously move said plates inwardly.

To effect rotative movement of the plate 20, an arm 22 projects radially therefrom and outwardly of the bed plate wall througha slot therein. Secured to the link and to a pin 24 on the casing is a retractile spring 25 which normally urges the rotative ac- 1 tuating plate 20 to a position wherein the folding plates are in. retracted or initial position. The plate 20 is rotated tomove the bending plates to operative position by a cable 26 secured to the arm 22 and extending forwardly of the machine and about a pulley 27 at its forward end and thence downwardly for attachment to a pivoted treadle 28.

To raise the pocket book body coincident with actuation of the bending plates 11 and 13 whereby the edge portions of the body are properly fed for bending operation a false bottom 2.) is slidably fitted in the recess 10 of the die plate 9 and a shaft 30 projects outwardly therefrom through the bearing sleeve 21 and is ap'ertured at its lower end for the loose reception of one end of an intermediately pivoted lever 31 which has its other end apertured to loosely receive a rod 32 extending downwardly through a slot '33 in the table 6 for pivotal engagement with the treadle 28. A head 34 is formed at the upper end of this rod and adapted to abut the lever to swing it and thus raise the false bottom 29 in the recess subsequent to the initial portion of opera tive movement of the bending plate. The

movement of this false bottom 29 also serves conducting material and provided with a cured by links 42 pivoted thereto and to crank arms 43 on a shaft 44 journaled'horizentally in the bed casing. This shaft being actuated by a handle arm 45 projected therefrom.

pressing and heating action at the edge portions of the folded pocket book bodies the intermediate bottom portion of the block 35 is cut away and fitted in this cutaway 7 portion is a preferably wooden block 46 to the bottom face of which is secured a thin metallic plate 47, the edge portions of which project under the edge portion of the block 35. To adapt the heating and pressing member also as a guide means for the edges of the work material during the bending operation thereof, in which instance itis not desired to exert a heating operation the block 46 is slidably mounted in the cut away portion of the block 35, being held therein and resiliently urged to retracted position by a leaf spring 48 secured to its inner'face and having its ends engaged in passages 49 formed in the block. Pivoted to an up standing ear 50 at the rear end of the casing is a bar 51 which extends through and is vertically slidable in a transverse passage 52 formed in the block 35 inwardly of the a block 46 and this bar extends forwardly of the pressing and heating member and is notched at its forward end for engagement with a hook member 53 which is manipulated by means of its pivotal connection with a plate 54 vertically slidable in a guide channel 55 on the front bed plate wall, and this plate is connected with the treadle 56 below the table by a link 57. V V l Taking up now the operation of the entire machine a flat pocket book body is first laid over the recess 10 of the die block 9. A flat holding plate 58 is placed on the body member and pressed to force the body mem bar into therecess 10, this plate being of but slightly less area than the area of the recess whereby the pocket book body and plate are frictionally held by their disposition in the recess this phase of the operation being indicated in Fig. 6. The handle 45 controlling the pressing and'heating block 35 is then swung forwardly to depress said block, and the treadle 56 is depressed to swing the hook 53 into interlocking engagement with the bar 51. The handle 45 is then partially lifted to raise the block 35 from the bed 8O Inasmuch as it is only desired to exert a V 7 i is procured.-

plate and work material, the block 4L6 and guide plate a7 being retained in lower position by reason of the hook 53. The operator then depresses the treadle 28 to operate the Y, bending plates 11 and 13 and to raise the false bottom 29 of the recess as heretofore described, it being noted that the plates 11 and inc inwardly between the bed plate and the plate 457 wl ereby exact folding lV th the bending treadle still depressed, the operator then pulls downward with considerable s ig'th upon the handle 45 thus pressing the rolded pocket book body between the raised false bottom 29 and the heating and pressing block 35, this position being retained for a suiiicient length of time to heat and sufliciently press the pocket book body to permanently retain the folds therein. During these pressing operations the treadle 56 controlling the hook 53 is released and upon the pressing operation being completed the handle 45 is swung backwardly lifting the heating and pressing block 35 and the folded pocket book body is removed, the plate 58 being subsequently detached therefrom.

In removing the die block 9 for replacement of another die block having a different shaped recess 10 to accommodate pocket book bodies of difierent shape it is obvious that it is necessary also to provide substitute sets of plates 11 and 13 and substitute false bottoms 29.

While I have shown and described a preferred form of my invention it is obvious that under differing conditions of use various modifications may be resorted to, hence the spirit of the invention is limited only by the scope of the appended claims.
