Fig. is. asectioual view ofgthe frame work 1n Figs.' I 7, 8 and 9. (putI together as ninvFigs. 1 and 2) on the lines c-c, 4d and e-e respectively,

exposing the A mechanism contained within the chambers thus intersected; the dog 11 is omitted; Fig. 12 is a section on the line f--f in Fig. 7 ofthe wipers only. l Y

Referring to' t-he'drawizgs by reference numerals, l designates the main frame or bed of the machine which may be secured to the floor by' screws 2. Inview ofthel position of theheel and toe of the last 3 and shoe 4 in-Figsf1 and 2, I will for shortness refer to the' left hand end of the machine' as the toe end and the opposite end as the heel States, residing at.

j' rearend islprovided 'with 1u lc nd. twill then be'seen that'. above the' 'l1nes.g'-g'in Figs.:.2, 3 and tthe parts are' 'so similar 'that themfollowingdescription will answer for both ends. -Ina chamber having at .its rear ende ratchet rack 6 .and its top closed bya cover 7 with a slot 8 in it, is arranged a slide 9 (see F ig. 8) whose v 10 between which -is pivoteda dog l1 adapted to engage the racl-t andhold the slide-1n the desired forward position.,-"1`o'the,front corn rs of .the slide are pivotedat 12 ltwo links 13., -in whose front end's'fare fixed vertical pins 14 extending. upwardly through obliquelyc diverging slots 15 inthe cover and engaging in holes in tliz rear ends of two plates ll' known "as thgi wipers',.'because their front ends are formed with rounded edges 17 adapted to act in a Wiping'mnnner to' gather the edges llSof the'l upper leather upward and inward upon the sole 19 which is tacked on the last,"and hold them while'they are bcing tacked to the vsole and-the last preparatory to furtherwork on the shoe. The, pins 14 may also extendT downwardly into slots 15 in the bottom ofthe chamber. The wipers are pivotally-s'ecured 'together atf20; and at 'opposite sides. from said pivot cach wiper is provided with' a fixed pin 21,z whose lower end is guided inail obllqueslot 22 in the cover 7,.and its upper-end may be guided in 'similar slots 22* in a lid 23, which 1s hinged at 24 to lugs'25 of thel cover 7 and is held closed over the wipers .by a latch 2 6 pivoted upon alateral lug 27 .ofthe cover 7 the latter having opstanding side.ribs 28 for the lic. to reston, a Wiper chamber 29 (see Y Fig. 7 is thus? provided for the wipers., The slide 9`is operated by a hand lever() pi'voted lat'witli one e'nd -t-o a bracket 31 fixed eitheiron the chamber 5 as shown, (or 'it may b: on the cover 7 thereof), and engaging a stud 32 projecting upward from the slide tfirough the slot 8 in the cover.

At the toe end of the* machine the chamber 5 hasahottom rib T34 whose ends are provided with cavities Sli for the points .of

pivot screws 3.6 to engage and trunnion the chamber soit may be'tilted to either side;

lic

. tached to a doublearmed foot lever 59, 60,

'v ,idsl'fo'f the leversI 75. The stud 81, is slid 4'end connected bya rod' 56 to a rack 57, which -each made 1n two'sections joined vtogether engaged by their upper ends. The slide 38 is adjustable 4to and from the lastby means of a screw 43 threaded in a .lug 44 of the frame -plate and having one end provided with a hand wheel 45 and the other end with an annular groove (not shown) engaged by a pin 47 in the slide.

The frame plate 40 normally rests upon a support-ing plate 48, which is pivoted at 49 tothe top of a support 50 provided upon the main frame 1. The frame.40 is provided with downward studs 51 guiding in holes in the plate 48, and isalso provided withlugs -52 projecting through slots 53 in the sup# porting late and'operated by links 54 and 'bell-cran levers 55, the latter being mounted on the support 50 andhaving each=one is slidable vertically between guides 58 fixed on the-support, and has its lower end at- 4whichY is fulcrumed at 61 and normally holds the rack elevatedjby the action of a spring 62 which supports the main arm 59 of. the lever. -On the support- 50 is further pivoted a finger operated dog 63, normally held inengagement with the rack ',by'a spring 67". The plate 48 may bev tilted on its joint 49, by` a 'screw 64, having its upper end connected to the plate by a balland-socket Vjointl 65 and 'its lower eid threadedin a nut block 67 trunnionedfin,y the support 50. To perm'it 'more readily 'such tilting the rods 56 are by aftngmbuckle 68. The screw` 64 is rvided'witha s1nall:wheelf69 by,which 1tis turned. 1

. At'the heel end ofthe machine the elements 49, 65, 67 and\69, being like the corresponding parts at the toe end, need no further description; but at the heel end it will4 be seen that the support 50", is not rigid but is a portion of a carriage70, sliding on'a TJ. shaped rib 71 at the top' ofthe bed-plate 1," and is operated by means presently??l to bej described, 'The heel end of the machine is' different from the toe end by having the.' frame plate 40 pivoted directly at tlief.'l joint 49, and' furtlicrhy haring l' \t\vcenthe rib 84 and the-slidechamber 5 a chamber 72, (see Figs. 4, 9, 10 and 11,) in which is located `the following pad-actuating mechanism.

In the chamber' 72 is slidably guided a plate 73, upon which are pivoted at 74 two levers' 75, to whose front ends are pivoted at 76 clamping-blocks 77, to which are secured the ends of the heel pad 78 (of leather or other flexible material),'whose middle is secured'by one or more screws 79 to apush bar 80,,`whose rear end is guided ona stud 1:"1 andy connected by links 82 with the rear blyfmouuted in a vlug' 83 V'of 4'the plate 73,

'd'hasvits rear end butting against the point-of a thumb screw 84 threaded in a lug 85 of the chamber 72. Said screw is to regulate the tension of a spring 86, which is interposed between the end of the push-bar 80 nd a nut 87 threaded upon the slidable stu As best shown in Figs..2 and 5, the carriagei hasa dovetail rib 88, on which slide two dovetailed blocks 89 and 90, each of which is moved and held by a hand screw 91, threaded through a lugv 92 ofi the carriage and swivel-jointed on a pin v93 inthe block, In the block 89.is threaded the lower end of a prop 94, whose top end 95 is crutchshaped to support the front part of thelast 3. In the block 90 is similarly threaded a prop 94, whose upper end asses into a hole siderable lateral strain, is guided in a bracket 98 fixed upon the prop-carrying block 90.

Forpurpose-of moving the carriage 70, it is provided with a rack 99, which is engaged by the upper edge of a cog-wheel 100, mounted on a stud 1014on the frame, and having its lower edge engaged by a Adog 102, pivoted to the lower endof a hand lever 103, which is also mountedon the studvlOl and is provided with a finger lever 104,. whose spring 10.5 causes the dog to normally engage the cogs of the wheel. The. wheel is h eld in any desired position by a dog 106 normally held in engagement with the wheel by a spring 107, said dog has an arm 10S, for the operator to press on with hisvfoot to disegage the dog while he operates the handlever 108 and the nger lever thereon so as tomove the carriage toqthe desired position or proximity to the toe end of the machine, according to the length of the shoe to be operated on.

To keep the last firmly down upon its supporting props during operation, l provide.l asin Fig. 5, a pair of bool; levers 109 adaptedto take holdvupon the last 3- as shown.' The said hook levers are pivoted at 110 together and to a foot lever 111, which is are formed with lateral fingers 116 adapted to engage the inner edges 117 of a 'cam bracket 1.18, fixed on the carriage, and thus spread the-upper ends of theA hook levers to 'the dotted positions. shown in Fig. 5. When the foot lever is down it may be swung slightly sidewise and thus engaged and held down by a catch 119 on the main' frame.
