rnnnnr n. at, or BROOKLINIE, nassncnnsnrre,
application filed. Aprfl l, 1916.
To all whom it may concern:
Be it known that l[, Pnnnnr R. Grass, a citizen of the United States, residing at Brookline, in the count of Norfolk and State of Massachusetts, ave invented certain Improvements in Punching and Folding Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures This invention relates to machines for op erating upon the margin of a piece of flexible material and is herein illustrated in connection With a machine for folding the margin of a piece of upper leather and for forming along said margin a row of ornamental perforations.
It is customary to fold the margins of cer-. tain parts of shoe uppers and to ornament them by a row of fancy punch holes, and although Vamps, foxings, etc., are very commonly so treated the present invention w ll, for convenience, be described in connection with a machine speciall adapted to fold and attached to the end of a short vamp by a row or rows of stitches located near one edge of the tip; and this edge, in a flat died-out tip is slightly curved.-
Hitherto it has been customary to skive the margin of the tip, then to cement the skived margin, then to fold said margin on a suitable machine and finally to form the ornamental perforations by means of a punching machine. According to the present invention the skiving and cementing are carried out as before, but the folding and punching are accomplished progressively in a single operation.
One feature of the invention comprises, in a machine of the class described, a support for a piece of stock, means for feeding said stock intermittently over said support,
means for forming afoldin the margin of said stock, means for hammeri the fold, and means for unching the stoc near the edge thereof a er the fold has been, made.
With such a construction the two operations of folding and punching are going on at the same time whereby the former practice of performing two separate operations is ohviated and a large saving of time is eflected.
he tip is ordinarily atented ept. a, ran.
N0. htfitil- I Another feature of the invention coniprises in a machine of this general type, a feed member movable in a path the curve of which corresponds approximately to the curvature of the edge of the material which is to be operated upon, and an edge ge to facilitate proper location of the stori with respect to the feed member. 18 these means s insured uniform folding an punching of the difierent pieces of material, a result which is diflicult to secure when the two operations are performed separately.
These and other features of the invention including certain details of construction and combinations of parts will be described in connection with an illustrative machine'by which an exemplary method may be carri out and will be pointed out in the appended claims, Referring now to the accompanying drawin w igure 1 is a front elevation of an illustrative machine in which the invention in embodied;
Fig. 2 is a perspective of the mechanism Fi 3 is a detail, partly in section, showing t e connection between the clamp and the feed member;
Fig. 4: is a detail perspective of a portion of the clamp;
Fig. 5 is a perspective machine;
Fig. 6 is a detail perspective of the punch and its operating mechanism;
Fig. 7 is a detail, principally in section, showing more particularly the whole punch in mechanism, and
ig. 8 is a erspective of a shoe tip which has been fol ed and punched on the machine.
The present invention is illustrated in connection with a foldin machine which is similar to that shown an described in British Patent No. 15,405 of 1912. The present machine, like that of the patent, comprises a fiat bed or support, herein shown as comof the top of the posed of two plates 1 and 3, over which the the margin thereof about the end of the creaser to form the fold, and an oscillating hammer or presser 207 to press the fold thus formed. In the machine of the patent the hammer co5perates with an anvil to grip the fold; and while the work is thus gri ped the hammer and anvil are moved in a 1rection to feed the work. In the present machine the movable anvil and its operating mechanism, as well as the mechanism for moving the hammer in the direction of feed, have been omitted, and a separate feed mechanism which will presently be descrlbed has been provided. No further descriptlon of the folding and pressing mechanlsm will be given since its details of constructon form no part of the present invention and any suitable folding and pressmg mechanism may be employed. The partlcular mechanism illustrated in the present machine forms the subject-matter of certain prior United States Patents Nos. 1,270,753 and 1,281,555.
The two plates 1 and 3 have formed between them a segmental guideway 5 to receive a segmental rack 7 the'curvature of which is approximately the same as the curvature of the edge of the piece of upper material which is to be operated upon. In the operation of the machine the shoe tip 100 is clamped to the rack, and the rack is then moved to present the margin of the tip progressively, first to the folding mechanism which has been indicated above, and then to the punching mechanism shown in Fig. 7. The clamp 9 (see Fig. 3) is connected by a stem 11 with a block 13 having in it two vertical bores. A pin 15 driven tightly into a socket in the rack 7 is encircled by a spring 17 which tends always to hold the clamp 9 in contact with the rack 7. In order to maintain the clamp in proper alinement with the rack a second pin 19, loose in the second bore in the block 13, is held in a socket in the under side of the rack 7 by a coiled spring 21, a handle 23 being provided to permit this pin to be withdrawn from engagement with the clamp when desired.
In order to raise the clamp 9 at the end of the punching and folding operation, the lower end of the pin 15 has formed upon it a rack 25 with which a pinion coiiperates, so that by turning the pinion the clamp 9 may be raised against the action of the sprin 17. Automatic turning of the pinion to raise the rack is accomplished through a crank 29 fast to the stem 127 of the pinion and a curved rod 31 having adjustably fastened thereon a stop collar 33 (see Fig. 1). The rod is slidable through a hole in a part of the frame of the machine and moves with the segmental rack 7 until the collar strikes the frame, after which further forward movement of the rack causes the rod 31 to pull the crank 29 and thereby to raise the the spindle 51 on which the beveled gear 45 is loosely mounted, and an intermittent gri device 53 rotatable on the spindle 51 and adapted to impart rotation to the clutch member 49. Since any suitable intermittent gnp device ma be employed the one illustratedvwill not e further described. On the back of the beveled gear 45 (see Fig. 1) is a tapered cam 55 which, when the beveled gear has nearly accomplished a revolution, engages an abutment on a yoke 57 between the arms of which the clutch member 49 is revolubly mounted, thereby swinging said yoke to the left about its pivot 59 and separating the clutch members 47 49. A spring pin 61 holds the yoke lightly as shown in its rearward position after the yoke has been moved as described above. When the yoke has thus been moved, the feeding rack 7 has reached its extreme forward position, the clamp 9 has been raised by the pull of the rod 31, and the punched and folded tip may be removed from the machine. To permit the rack 7 to be returned to its initial position a strap 63 has one end fastened to a drum 65 which is integral with the hub of the beveled gear 45. When the rack has been returned to its initial position by pulling upon the strap 63 the clampe9 is still raised to permit a new tip to placed in position, and the clutch members 47, 49 are still separated.
In order to cause these clutch members to engage so as to start the feeding movement of the rack and to trip the latch 35 so as to permit the spring 17 to lower the clamp 9' upon the tip, the following mechanism, shown best in Fig. 2, is provided: A bell crank lever 67, the horizontal arm of which is connected with a treadle rod 69, has its upright arm arranged to engage a boss on the yoke 57 when the treadle is depressed whereby the clutch member 49 is moved into engagement with the clutch member 47. This bell crank lever 67 is also connected with a rod 71 slidable in a boss on the frame of the machine and provided at its upper end with an arm 73 which overhangs the tail of the latch 35, a spring 75 tending to hold the rod 73 and bell crank lever 67 in the position shown. When, theretore, the treadle is depressed to throw in the clutch the arm 73 disengages the latch 35 from the rack 7 and-permits the clamp 9 to be brought down upon the tip or other piece of work, the
amazes The intermittent grip device 53 1s operated continuously. through a link 77 pivoted at oneend to a movable part of said device and at the other to an arm 79 fast on a rock end an arm 83 to the outer end of which is pivoted the upper end of a forked link the lower end of which is pivoted to a-block 817 adjustable in a slot in an arm 89 so that the extent of the intermittent feed movements may be regulated. The arm 89 is identical with the feed operating arm in the machine of the British patent referred to above. It is pivoted about a rod 91 and is oscillated continuously by aneccentric93 on the driving shaft 95. If it isdesired at any time to change the extent of the intermittent feed movements the position of the block 87 in the slot in the lever 89 may be changed by rockin about its pivot 133 a yoke 135 which em races a pin 137 carried by said block. To facilitate so rocking the yoke, a
The punching is done from beneath, since the lies grain side down on the feed rack 7. e punch 97 (see Figs. 6 and 7) is mounted on an arm 99 pivoted to the frame of the machine at 101. The outer end of the arm carries a roller 103 held down on a cam 105 by a spring 107. The cam is fast to a ear 109 driven by a small gear 111 which is fast on the main driving shaft 95. The gearing by which the punch is actuated and the cams and levers by which the intermittent grip device 53 is actuated are proportioned and adjusted in accordance with the pattern of punch which is used. In the present machine, with the parts adjusted as shown, two intermittent feeds occur to one punching operation.
Referring now more particularly to Fig. 7, the punch block 113 has a stem 115 adjustably held by a set screw 117 (Figs. 1 and 5), an adjusting screw 119 being provided to facilitate proper positioning of the block. The block, as well as certain elements of the folding mechanism, is mounted upon an overhanging arm 11.2. The block is provided with a passageway having guides-121. Through the passageway, around the guides, and across the face of the punch block runs a strip of paper 123 which furnishes a backing for'the tip during the punching operation and thereby insures clean cut punch holes. A U-shaped guide 125 adjustably fastened to the arm 112 holds up the upper run of the paper strip; and the strip is wound from one roll to another in anysuitable manner, for. example by a reel stand such as that shown ,in' United States Patent No. 941,704, connected by abelt with a pulley 129- on the driving shaft 95. The
operation of the machine is as follows:-
Starting with the parts in the position shown in Figs. 1 and 2 with the clamp 9 raised and the rack 7 in its starting po-. sition which results from pulling down upon the strap 63, the operator places a tip 100 between theclamp and the rack with its edge which is to be folded against the gages 131. He then depresses the treadle rod 69, the effect of which is to trip the latch 35 thereby permitting the spring 17 to bring the clamp 9 down upon-the tip and throwing the clutch members 47, 49 into engagement. The tip is then fed intermittently first past the folding and pressing mechanism and then past the punching mechanism with the result illustrated in Fig. 8.. To-
ward the end of one revolution of the beveled gear 45, the cam 55 .engages the yoke 57 to separate the clutch members, and the rod 31 exerts. a pull on the crank 29 to raise the shown in said figure except that the rack is at the extreme end of its feeding movement.
The operator then removes the punched and folded tip and pulls down on the strap 63 to return the rack to its initial position.
Although the invention has been set forth in connection with .a particular machine, it should be understood that the invention is not limited in the scope of its application to the articular machine shown and described.
aving thus described my invention, I claim as new and desire to secure by Letters Patent:.
