MACHINE FOR MARKING LEATHER.
Application led November 13, 19724. Serial No. 749,632.
To all whom it may concern Be it known that I, CARL citizen of the United States, and resident of Manchesten county of Hillsborough, State of New Hampshire, have invented an Improve- 'ment in Machines for vMarking Leather,
. ufacture of shoes.
of. which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing likeparts.
4This invention relates to a'machine for marking leather or other sheet material for the pu'v pose of providing the latter with guide ypoints or guide lines. As illustrating one use to which the invention may be put I would refer to the man- In making shoes of some types it is customary to mark on pieces of upper leather before they are stitched together certain guide indications which may be in the nature of guide lines to indicate `where the line of stitching should be placed,
or may be in the nature of guide indications to shovsT where buttonsy should be sewed to the upper or eyelets should be punched.
. Thefpresent invention has for one of its objects to provide a novel machine by which such indicating marks can be made on the pieces of leather that are used in the manufacture of the shoe, orl in fact on pieces of any sheet material, becausethe invention is not limited in its use to the marking of shoe uppers. A
The marking of the leather or other sheet material vis accomplished by plac'ng on the leather a marking temp-let which as marking projections on the face thereof which engages the sheet material and by pressing the templet against the sheet material yto cause the project-ions to make indent-ations therein. If the sheet -material is to be lmarked to give a guide for a line of stitching, for instance, then the templet will have formed on its operative face a plurality lof projections arranged in a line corresponding to the desired line of' 'stitching so that when thetemplet is pressed against the sheet material'thline of indentations formed therein by theprojections will give the guide -for One feature of the present invention re- Alates to a novel manner of retaining the templet land sheet material in position while the templet is subjected to pressure.
The marking will preferably be done in a machine having the nature of a press in C. HAYDEN, a
plet is held in position on the work support' by magnetic means, the work support eing provlded .wlth suitable magnets which by their magnetic attraction hold the templet in position, it being understood that the templet is of a material which is responsive to magnetic attraction.
.Other features of the invention relateyto Aa novel construction bywhichthe work support is movable into and out of a position beneath the presser memberfsaid work 'support when withdrawn from beneath the presser member being in position where the operator can readily place the work thereon and i by its movement beneath the presser member .carrying the work into position to be marked'. y u
When the machine is set in operation the Work support will be carried into a position to bring the work beneath the presser mem-r ber and then said member will make its operative movement to subject the templet to .pressure and cause it to mark the goods after which the Work support will be returned to its initial position. As stated above the work is heldin position during this movement of the work support by magnetic means.
Other features ofI the invention have to do with various improvements in machines of this type all as will be more fully hereinafter set forth.
In order to give an understanding of the invention I have illustrated in the drawings a selectedv embodiment thereof which will now be described after which the novel eatures will be pointed out in the appended claims.
In the drawings:
Fig. 1 is a side view fof a machine embodylng my invention;
Fig. 2 is a section taken on substantially the line 2 2, Fig. 1; j
Fig. 6 is a reduced section o'n substantially the line 6 6, Fig. 1 showing the work support in plan view;
Fig. 7 is a perspective View of a. 'templet embodying the inventionsuch 'as would be used in marking a shoe upper to indicate the proper position for a line of stitching;
Fig. 8 is a perspective view of a piece of leather which has been marked with the -templet shown in Fig. 7;
sheet material accordin to this invention involves the use of a s eet metalumarking piece of contour of the material 1 to be marked andv templet having marking projections formed on one face thereof and also involves pressing said face of the templet against the sheet material to be marked to cause the projectioilis to make indentions in the sheet materia It will be` obvious that a templet embodying this invention may be used for marking a great variety of articles and as' illustrating one-such use I would refer to the marking of the quarters of a shoe upper to indicate the line to be followed in stitching the quarter to other partsof the shoe.
In Fig. 8 one ofthe quarters of a shoe upper is indicated at 1 and the line to be followed in stitching the quarter to other parts of the shoe is indicated by the line of indentations 2. The templet which is used in producing this marking on the sheetl material 1 is indicated at 3 in Fig. 7 and it is a sheet metal having preferably the provided on one face with a plurality `of projections 4 which have anl arrangement i corresponding to the marking which it is desired to produce on the quarter 1.
The marking operation is accomplished by placing the work 1 on a suitable work sup- A port 5 -superposing the marking templet 3 on the work and then subjecting the templet to pressure by means of a plunger or presser member 6 which forces the projections 4 intothe surface of the work 1 and produces the indentions.
The presser member 6 is in the form of a vertically movable plunger and the work support 5 is\ mounted for movement in a direction transversely to that of the presser member. The presser member has a shank or stem 8 which is movable vertically in guides 9 carried by a suitable frame 10, said presser member deriving its vertical movement from a crank 1l on a. drive shaft 12 which is journalled in the' frame land is operated by a suitable drive pulley 13.
'Ihe frame is shown as provi ed'with a horizontally-disposed slideway 14 on which the work support slides back and forth from the full to the dotted line y.position Fig. 1. .When the work support is 1n the full line position Fig.' 1 it is withdrawn from beneath 6. e operation of marking ient position for the o erator to place the work and the templet t ereon. The lmovement of the work support into the dotted line position carries 'the/templet and work beneath the presser member 6 so that when the latter descends it will press the templet against the work and thus .perform the marking operation..
Means are provided for -reciprocating the work support in timed-relation to the movements of the presser member. Said work support is shown as provided with a rack l5 on lits under face which meshes with a gear 16 on'a shaft 17 extending transversely of the frame. This shaft 17 has fast thereon a smaller gear or pinion 18 which meshes nected by a link 24 to a crank pin 25 formed on a crank disk 26 which -is fast on the driving shaft l2. The vertical reciprocating movement of the rack 22 will thus operate to moveqthe work support 5 back and forth horizontally on the ways 14.
The construction of the work support moving mechanism above described is such that during .the first part of the downward movement of the .presser member 6 the work support will be carried into position beneath said presser member and will remain at rest in such position during the final downward movement 'of the presser member and while the marking is being accomplished and also during the initial upward movement of'said presser member.
For accomplishing this I use a rack'n22 of such length relative to the throw of the crank 25 that therack will run out off-mesh with the pinion 21 before the crank 25 reaches its lower dead center and just at the` time that the work support 5 has been carried into the dotted line position Fig. 1. In
order to prevent overrunning of the work support due to momentum I propose to provide the gear 21 with a sto member 27 which is adapted to engage t e face 28 of the guide 23.]'ust-at the time that the rack 22 runs out of mesh withl the gear 21 as 'shown by dotted lines'. in Fig. 1. With this construction it will be seen that durin the first part of the downward stroke o the vpresser member 6 the work support 5 `will be carried into the dotted line position and will be brought to rest by the engageyment of the stop 27 against the stop face 28. At this time the rack 22 runs. out of mesh" with the gear 21 so that during the remaining portion ofthe first half revolution ofthe crank shaft which carries the presser member to its lower int the rack 22 will simplyV move away rom thegear 21 and the work supportv 5 will remain stationary.
During the other half revolution of the shaft 12 and when the presser member has been partially elevated the rack 22 will again come into engagement with thepinion 21 and will return the work support to the full line position Fig. 1 by the time the presser member 6 is fully elevated.
As stated abovesone feature of the invention relates to magnetic means for retaining the templet 3 in place on the work while the work support is moving from the full to the dotted line position Fig. 1 and during the marking operation. This is provided forby constructing the work support with magnets and by making the templet of material which is magnetically responsive 'so that when the magnets'are energized they hold l the templet in place by magnetic attraction.
The character of the magnets may vary more or less without departing from the invention. In the drawings there are shown two magnets incorporated in the work support, each magnet having 'a winding 29 and a core 30. The number of magnets, however, may be varied depending on the size of the temp-let.
The work support is herein shown as formed with a base member 31 which has guides 32 that engage the ways 14, an intermediate member 33 in which the magnets are placed and a top. plate or face plate 34 lwhich willpreferably be of fibre or some insulating material. The cores 30 of the magnets are shown as extending abo-ve the yvindings and into openings 35 formed in the face plate 34 so that the top faces vof the cores come flush with the top face of the face plate. 4
The current is delivered to the windings 29 through shoes or' brushes 36 which are carried by the base plate 3l and which slid- Asupport is preferably yieldingly supported so that the operative face of the work support may yieldl slightly to accommodate different thicknesses of material and material. which varies in thickness from 'one edge to.
the* other. The yielding support4 for the member 33 is provided v'for by means of a vplurality of supporting springs 42 which are received partial in recesses 43 formed in the intermediate member '33 and partially in v recesses 44 formed'in the base member 31.
These springs support th'e weight of the'v member 33 and hold it normally slightly separated from the base plate 31 but they permit a yielding movement of the work if such is rendered necessary by thev fact that different pieces of' work vary in thickness.
l45 indicates screws which pass through apertures in the base member. 31 and are screwed into the member 33, said screws limiting the expanding movement of the springs 42.
I will preferably employ a one-revolution clutch for connectingthe driving pulley 13 to the shaft 12 and t-he clutch which I propose to use is one which will not repeat even though the treadle is retained in 'depressed position. The clutch itself may be of the familiar type which include-s a springpressed clutch pin or dog 46 slidably mounted in a collar 47 that is fast on the shaft 12 and which is adapted when released to engage a notch 48 formed in the driving pulley 13. When the clutch is released the clutch dog is held withdrawn yfrom lthe notch 48 by means of a controlling member 49 which is-shown as pivotally mounted at 50 and which has a wedge-shaped or pointed end 51. The pivotal movement of this controlling member 49 permits it to be swung from the operative position shown in full lines Fig. 3, and in which it is in the position to engage the projection 52 on the clutch dog, to the dotted line position Fig. 3 in which it is withdrawn from the clutch dog thus permitting the latter to operate. v
lVhen the controllinvf arm 49 is swung into thedotted line position Fig. 3 and lthe clutch dog is released it will automatically engage the notch 48 in. the clutch pulley thus clutching the pulley toI the shaft.
When the arm 49 occupies the full line position Fig. 3 then during the revolution of the collar\ 46 the projection 52 will ride up on the -wedge surface 51 thus disengaging lthe clutch. The arm 49 is controlled by a suitable treadle (not shown) and also by a spring 53 which tends normally to swing it into its operative position.. The treadle is connected by a link 54 to one end of a rocking lever 55 pivoted at 56'. The other end of said lever rests against a thrust rod. 57 which, extends Vup through an opening 58 formed in an arm 59'that is rigid with the controlling'arm 49. The thrust rod 57 has a shoulder 60'thereon which engages the under side of the arm 59 and with this oonstruction it will be clear that when the treadle is depressed and the vlever 55 is rocked into the dotted line position Fig. 3 the thrust rod 57y will be-elevated and thereby operating through ,theshoulder -60 and arm 59 to swing the clutch-controlling member 49 into its dotted line-position.
Means are provided whereby'the control ling'member 49 will be allowed to return to its' operative position before' the shaft 12- makes a complete rotation even though the treadle is retained inV depressed position. To accomplish this purpose the opening 58 of the'arm 59 is somewhat larger. than the thrust rod 57 so that the latter can umove laterally therein and the collar 47 is provided with a cam 61 which is adapted. to
engage a projection 62 carried by the upper end of the thrust rod. 'lhe engagement of the cam 61 with this projection will swing the upper end of the thrust rod to the right Fig. .3 into the dotted line position Fig. 4 thus releasing the shoulder 60 from engagement with the arm 59 and allowing the spring 53 to swing. the arm into its operative position. The clutch will, therefore, be disengaged at the end of each revolution regardless of whether the treadle is held depressed or is released.
63 indicates a spring which is connected to the thrustf rod 57 and which normally returns it to its lowered position when the treadle is released.
It. is only necessary that the magnets lshould be energized while the machine is operating. In fact, it is not desirable that they should be energized when the operation has been completed as otherwise the operator would be obliged to remove the templet from the work against the magnetic attraction of the magnets. I have, therefore, provided novel means connected with the clutch by which the circuit to the magnets will be opened when the clutch is'disengaged and will be automatically closed when' the clutch is thrown into engagement. For thisV urpose I provide a switch in the circuit othe magnet which is closed automatically when the clutch is thrown into engagement and is opened when the clutch is disengaged. While various v.types of switches may be employed for this purpose that herein shown `is one which comprises two contact members 64 and 65 connected to the two sides of the circuit and a bridging contact 66 which is acted on by a spring'67 that normally tends to close it against the contact 64, 65.
This bridging contact 66 is formedwith a stem 69 which is situated to be engaged by the clutch pin 46 when the latter is withdrawn, the.construction being such that the withdrawing movement of the clutch p-in 46 operates throughthe stem 69 to separate the bridging contact 66` from the other contacts 64,65. Therefore, when the clutchv is disengaged the switch will be opened and the magnets de-energized. The operation of throwing the clutch into engagement by releasing the clutch pin 46 willl allowthe a, spring 67 to close the bridging contact 66 against the stationary contacts 64, 65 thus closing the circuit to the magnets. With this construction the magnets will'be energized only when the clutch is engagedand fthe machine is in operation and as soon as `the machine comes to rest at the end" of a cycle of operations the circuit of the magnet is opened and the latter is de-energized so that the templet is free to be removed from the work.
