MACHINERY COMPANY, OF BOSTON, MASSACHUSETTS, 'A CORPORATION OF MAINE.

To all whom it may concern:

Be it known that I, ANGELO PERRI, a citizen of the United States, and resident of Bellingham, county of Norfolk, State" of Massachusetts, have invented an 'Im rovement in Machines for Lasting Stitchedown Shoes, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to a machine for lasting stitched-down shoes and'particularly to a lasting machine of that type which has a, member or element against which the shoe is held during the lasting operation and which operates to tuck or press the upper 'into' the angle between the side of the last and the projecting margin of the sole, and

a beater cooperating with said member to beat or press the marginal portions ofthe The feature of the present invention relates to an improvement in the tool or ele-- Inent operating to" press the upper into the angle between the sole" and the side of the last which tool accomplishes its function without distorting or wrinkling the upper as the shoe is fed past the tool. This end is accomplished b providing a rotary tool or member and a so by providing means for positively rotating it Sothat 'its action against the upper will counteract any tendfeatures will be pointed out in the appended claims.

' Application jfiled March 3, 1921. Serial No. 449319;.

Patented Nov.'29, 1921.

The machine herein shown comprises a work-supporting member against which the upper face of the projecting portion of the sole of the shoe is held, and a beater or presser elementcooperating with said worksupporting member to press together the marginal portion 4 of the upper and the marginal portion of the sole. This worksupporting member "comprises a disk-like member 5 and a bed member 6, the latter being received in a'recess 7 formedin the under side of the member at 5 and the under face of the two members 5 and 6 forming chines of this type. These parts are supported on a suitable frame9. The beater 8 is carried by a slide 10 that: is slidably mounted in ways formed in a carriage 11 that in turn is constructed to reciprocate vertically of the frame 9. The slide 10 is yieldinglyconnected to the carriage and for this purpose the slide'is provided with an apertured boss 12 through which extends an adjusting screw 13 that is screw-threaded into the carriage 11, said screw carrying a spring 14: which provides the yielding connection between the slide and the carriage; The carriage is provided with rack teeth 15 which are engaged by teeth formed on a lever 16 pivoted to'the frame at 17 'andsaid lever is actuatedfrom a crank pin 18 on a driving shaft 19, said pin being connected to the lever'by the link 20.

The partsas thus far described, with the exception of the member 5, are substantially the same as shown in the co-pending application of'Benjamin'S. La Fleur; Serial N 0.

416,605, filed Oct. 13, 1920 and in the operation of the device the shoe' is held as shown in Figs. 1 and 4 so that the edge member 5 will engage the upper in the angle between the side of the last and the projecting margin of the sole, and as the' shaft l9: isrotated the carria efll will be reciprocated verticallyv and uring each upward movement the beater Twill first be brought against the and?! fa e o the sole @Qltbir pressiiig'flie The carriage 11 is provided with a trima ming knife 21 which cooperates with the bed ymember 6 to trim or rough round the sole.

' marginal portions of the sole and upper together, and while such portions are being thus pressed together the carriage will have its final upward movement to cause the knife 21 to trim or rough round the sole.

In this invention the member 5 is mounted in a stationary support 22 which is adjustably secured to the frame by means of a clamping screw 23 which operates through a slot 24 formed in the support 22. This ad justment is provided so that the operating edge of the member 5 maysbe adjusted nearer to or farther from the cutting knife 21, thus providing for trimming the sole so as to the last. V c

i In using the machine, if it be assume l'that the shoe is held against the member 5, as shown in Figs. 1 and 4t and then is moved in leave the desired width projecting beyond the direction of the arrowa in Fig. 6so'as to cause the member 5 to follow thecontour V of the last, the frictional engagement between the marginal portion 4: of the shoe upper and the under face of the member v5 will-tend to pull the marginal portion 40f the upper in the direction opposite tothe arrow a thus distorting the upper and preventing perfect lasting] of the shoe. In order to counteract all this distortion of the marginal portion of the upperylpropose/to rotate the member 5 positively and in'such a direction that the rotation'thereofwill offi set; the tendency to distort the upper above referred to. For thus rotating the member 5 I have shown it as rotatably secured to a gear 25 which in turn is fast on a shaft 26 that isrotatably mounted in the support 22. The gear 25 mesheswith and is driven by a gear 27 whichis fast on a shaft 28"also sustained in the-support 22 and this shaft 28 is connected" by beveled gears 29 toa horizon tal shaft that is journaled in bearings 30 and 31' and provided with gears 32 by which it is driven from a shaft 33" journaled-in the frame 9. This shaft 33 inturn is driven from the'shaft 19 by suitable gears 34.

".VVith this arrangement the member-5 is rotated in the direction of the arrow in 7 Fig.6 and as a result, when the shoe is fed, as shown by the arrow at, the dragging movement of the upper against the member 5 will be overcome by the rotation of the 7 member 5 and thus the upper will belasted without being distorted.

In order to permit the adjustment of the support 22 on the frame, as above described, I propose toma'ke the shaft journaled' in the bearings 30, 31 in two sections haVinga tele scopic" relation. These two'shaft sections are indicated at'35 and 36 respectively. The

.lshaft wsection '36 hasvthe tubular portion'37 into. which the end of the shaftsection 35 extends, said shaft section35 having a pin 7 38 operating ing; slot 3-9zformed in thetubu- :lar portion 37; In this way' adriving coniiig. member.

nection is always provided for rotating the member 5 but at the same time the support 22' with itsbearing30 canbe'adjusted on-the frame without interfering with suchdriving connections.
