To all 'whom t may Be it known that I, LEWIS J. BAZZONI, a

4citizer/ of the United States, residing at' Swampscott, in vthe county" of Essex and nection with the accompanying drawings, is s a specication, like reference characters on indicating like parts lin rthe several figuresl" This invention relates tothe formation of perforations or indentations 'in a piecev of, material and the application1-' vof a coating4 or other substance to the edgesrof -suchperforations or indentations, and ifs hereinillustrated in connection vwith vamachine for forming perforations in pieces of leather y"and for inking the edges-of such perforation's.

In the manufactureof boots vand shoes it. is' customary to ornament the tips and certain' other portions of the upper by forming i the margin'thereof a row of perforations. ,Inasmucln however, as the dye wlth which the leather is colored seldom permeates the leather-completely, the edges of theperforations are usually of-a'color different from that of the surface of the leather. For example, when black leather is perfofn rated there is commonly exposed a stratum of lighter color. Hitherto, this stratum has been colored by 'dipping the piece of leather into ink. The dipping process necessitates the subsequent removal of the surplus ink which adheres to the surface of the leather, and this removal has been accomplished by lwiping oft1 the surplus ink with a piece of cloth. The coloring of the edges of the perforationshas thus involved a slow process, wasteful both of time and of ink or other coating substance. l -1 The general object of the present invention is to do away with the handoperations outlined above. v To this end one 'feature of the invention consists of a support for a perforatedpiece' of stock, a carrier Vfor a coating substance,

. and means for causing said carrier to enter said perforation. Each carrier for the coating substance 1s so formed Vand arranged-as to 4measure a predetermlned Aquantity of Specification of Letters Patent.

coating substance from the container andto transfer such predetermined quantity to the stock. Convenlentlythe carrier may be' the punch itself.v

Another feature of the invention therefore consists ofa supporty for a piece of stock, means for perforatlng said piece, and means for applying a .coating substance to the edge o f) the perforation. 1t is very desirable, particularly when parts of shoes are being operated upon, that the application of 'coatmg -substance be confined4 to the edge of the perforation so Athat none of the substance may escape upon-the lsurface of the leather.

` Another feature of the invention, then,

' jconsists of a supportv for a perforated piece of stock, means for applying pressure to the stock aboutth'e edge of the perforation,`

-andme'ans-for applying a coatingv substance to said edge'during the continuance vof said pressure. Here again,'if desired, thepunch itself may serve as a. conductor or carrier for the coating substance so that, as stated above, the .perforating and the coating may be accomplished in a single operation.'4 These and other features of the invention,

* including-certain details of constructionand combinations of parts,l will be described in connection with an illustrative machineand pointed out in the appended claims. Referring now to the accompanyin draw-l ings, Figure 1,is a front elevation o a machine in which the p resent invention is ernbodied, a part of the ink container being broken away to expose the punches; Fig. 2 is an endelevation of the machine viewed from the right of Fig.l y1, and Fig. 3 is a cross section on theline 3h55 of Fig. 1, the parts being shown inthe position occupied dufring the inking of the edge of the perforation.

Fast to the uprights 1 of the frame of the machine are brackets 5 in the grooves of which` ribs 7 of the ink container 9. are slidablefso that said container may readily be removedwhen desired. Mounted in verticalguideways 11 in the uprights 1 are slides 13.

Fast to the upper ends of the slides is 'a cross head 15, and similarly fast to the lower ends v coating substance is thus measured and cartively to/said slides.

ried from the container, and no more than such predetermined quantity can be transferred .at any one operating stroke of the punch.

The table or work support 23 is provided with sockets or bores 25 to receive the punches and has at its ends slideways which movably embrace the slides 13 so that said support may be raised and lowered rela- The purpose of raising the support is to force the stock tightly against the bottom of the ink container prior to the downward movement of the punches uwso thatwhen the punches have reached the position sho-wn in Fig-3 the ink in the recesses or pockets 9 may be elfectually prevented from rea-ching the surface of the leather. These relative movements of the work support and the cross head are brought about by the following mechanism: Sur-' rounding an eccentric 27 which is fast to the shaft 29 is an eccentric strap 31 to which is fast an arm 33. A pivot 35 connects thel arm 33 with a second arm 37 the hub 39 of which is fast to a rock shaft 41 mounted in the frame of the machine and held from longitudinal movement by collars 43. Yielding upward movement is imparted to the work support 23 from the rock shaft 41 through aspring 45 one end of which bears against a plate supported by an adjusting screw 47 threaded through a. portion of an extension 49 of an arm 51 the hub of which is fast to the rock shaft 41. The other end of the spring bears against the bottom of a socket formed in a second extension 53 of a second arm 55, said second armvbeing pivoted at 57 to the arm 51 and having at its outer end an enlarged.. portion 58 provided with an elongatedk eye 59 which coperates with a roll 61 the pintle of which is mounted in ears v63 formed 0n the work support 23.

'Thus when the shaft 29 is rotated theeffeet .of the rst part of the rotation is to rock the shaft 41 in a clockwise direction and thereby force the work upwardly against the bottom of the ink container 9, the pressure of the work support against the work'being progressively increased by thc compression of the spring 45 until the shaft 29 has been moved through 180.

In order to move the cross head 15 and the punches 19 downwardly as soon as the work support has pressed the work against the bottom of the container, the collars 43 have formed on their lower portions yokes pulley 81 by whichit may be driven, and

preferably a nerevolution clutch, not shown,of any approved type is provided to cause the machine to come to rest automatically in the position shown in Figs. 1 and 2.

As has been stated., the work support is provided with bores to receive the punches, and these bores open at their lower ends into a chamber 83 which receives the pills produced by thepunching operation. The punches may-be of any suitable form and in the illustrated machine are shown as being provided with V-shaped notches at their lower ends to facilitate the production of a clean perforation. o

In order to maintain a uniform level of ink in the container 9 a passage 85 leads into a cup 87 into which extends the neck of an inverted bottle 89 or other receptacle for ink.

T he operation of the machine is as follows: lith the parts of the machine in the position shown in Figs. 1 and 2 a piece of leather is placed upon the work support 23 and the driving shaft 1 is caused to make a revolution. The eii'ect of the first part of the revolution is..y to 'raise the work support and thereby press the work against the bottom of the ink container. 9. About the time this has been accomplished the yokes G5 engage the projections 67thereby rotating the arms 71 and pulling down the cross head l5 and the-punches 19. Meanwhile the spring 45 has been compressed still further so that when the 4punches reach the position shown in Fig. 3, wherein thel pockets have been moved from a position in the ink container into a position in which the ink is applied to the edges of the perforations, the work will be held very tightly and no ink can escape to the surface.- The further rotation of the shaft 29 restores the parts to the position shown in Figs. l and 2.

The invention has been set forth in con-4 nectionwith a machine for applying ink to the smooth edges of the perforations made in a piece vof leather by cylindricalpunches,

:but it should be understood that neither the nature of the stock in which the perforations are made7 nor the character of the edges or Walls of the perfor-ations, nor the substance .which is applied is material to the invention.

Although .in the illustrative machine the purpose of gripping the stock in the manner described prior to the punching opera'- l 30 substance. an

tion has been-stated to be to .prevent the ink from reaching the surface of the leather, it'` should be noted that it serves the further purpose of producing a clean perforation.

It should also be noted that the punches are at all times prevented from theslightest bending so that the perforations 'are perfectly true and uniformly located with vreference to one another. l

Throughout the claims the term coating substance Willbe used in referring to the substance Which is'app-lied, since itis evident that liquid, viscous, pasty, granulated v and other suitable substances or materials 16 may be employed if desired. 'i
