To all whom it may concern:

Be it known that I, SAMUEL J. WENT- WORTH, a citizen-of the United States, residing at Newport, .in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Heel- Seat-Forming Machines, of which the follow in is a specification .y invention relates to an implement for forming. the heel seat of a shoe bynniformly and smoothly turning over the. counter.

The object .of my invention is, first, to gather and turn over and lay down upon the ast-the up eror counterportion of a shoe. Second, to ammer'or press the turned over ed e so that it will lieinthe sha ed position. Thlld, to draw arid la over t e counters edgesmoothly u on t e heel of the insole avoiding al l wrin' es or uckers.

In the ordinary metho of forming the heel seat, the counter and upper are brought over by pincers and tacked down to hold them in. p a

co. Owing to the stiffness of the counter there are puckers ,or ribs 'betweenthe tacks leaving an uneven surface. Heretofore it was customary for the operatorto beat out by hand this uneven surface to form a .flat heel-seat.

In practical work with my invention, preferably, the upper andoounter are ulled over and secured-upon-the sole of the ast by two or three tacks, the last'is then presented to my machine which breaks over the counterand up er and lays them down upon the sole of the ast. This facilitates the work of the consolidated lastingmachine. After the ac-' tion of this lasting machine the lasted uppers are a ain sub ected to'my machine and the 'irregu larities are beaten out and a flat surface or heelseat-is formed. My machine'is 'ada ted to perform this character of work' in t e lasting of shoes in McKay work, welt work, or turned work. Also, my tool operates'advantag'eously upon the toe portions of the upper and is generally useful'in removing irregularities and more perfectly ada ting theupper to the last at this stage of t e manufacture -of boots and shoes.

The features of my invention are more fully setiforthin the description'of the ac-' wcompanyin'g drawings,- formmg a part of this Figure 1 is'a side elevation of ,my improv especification,- inhwhfch ment in: position for-use. 2 is an end elevation of the device shown m-Fig. with sleeve D an iheelend of the respective spr' contact therewith, and that t e opposite collar hasa cut away portion h adjacent 11o the guards removed.

These flanges form su orts for the irons. v

G represents beating members'or irons. These irons are preferably attached to the free end of the spring arms F,'by means of a lug a pro'ecti'ng from the lower edge of the 9.0 irons, and screw bolts b passing through the arms F and lugs. Theseirons arepreferably made curved and their .eneral outline is shown in Fig. 4, they are inclined and alter-' nately lap ed past each other. Said lug is' 5 placed bac of the center of the iron, so as toallow the forward end to'be depressedmore than the rear end for the purpose of;an"in-. ward drawing motion.

The collars. .engage under t e edges of the springs and they maybe set closer together or separated on. the sleeve D to adjust the tension of the p n It will be observed that the collars at the bars are in to desce'n r the-.-reg'ular distance. 1t Wlll'l)B observed-are wider at Th lia is doneit'o reate "an inward wipingaction,

to the drawing or wiping members disposed on a rotary member to afiect the Q eration herein set forth. It is also to be un' erstood that in the direction of movement of the rolry member the outer diverging ends ot-the.
