To all whom it muy concern.'

Bo it known thn l, (irnonon S. Cornu., u citizen oil the United Sintes. residing at Lynn, in lhe County oi' Essex und Slate of iliusuchusettn. have invented oeriuin lmprovements in Rotary hooleatin Mu,- frhinos, ol which rh@ following description, in connection with the ncf'onilmnying drnwings, is n Specifioation, like reference char- :ulers on the drawings indicating like pui-is in lh@ several figures.

This in vent ion relnles io machines for use in the manufacture of boots sind Shoes nud pnrtirulurly to Shoeelmping unlehinee und is: embfnlirul in n machine of the typo shown in printed British Pnlent No. 1fi.5S9 /08,

The invention comprises Certain improvementi;V upon the machine shown in that.. )intent designed to perfect the o'pention of that machine on verl'ain clueees of Work and to render tha nnu-,hine more durable.' This type of machine comprises n rotary hesiter flint includes :1 huh hnvinglr annular Hanger; lwtweon which flanges extend rods upon nach of which is mounted a' plurality of rings the interior diameter of which is suh- Sinntinlly grenier thun the dinxueier of the rod. This nrrnngfemont provides that. the rings' shall standout radially from the lau'o by miniriiugal notion while the beater is rotating' und that the rings may vivid inwsufdly when they strike the work und may swing hnckwurdly on the rods as they glide over he work in rubbing Contact therewirh. lt hns heen found in practice that life operation or' this machine is wonderfully eeo five in suoli work, as, for example, in heutu ing down the overlneiecl` margmal portionof an upper because of the great number of blows: Struck on the Work per minute'by the somewhat light ringo. The machine used commercially strikes about fortyoighf hundred blows per minute. This great eli'wi'ivonesn of'- Hio beider has led to iho extension olr :is field of operation and it is: now uned for heating out Soles of turn shoes: und ihfiwm ing the upper around the sides ol nimes for slmpiugr the upper ro the hief. lu thin` operation upon the shoe upper und upon the dump tempered Soles of turn shone ii han been found that the rings of the nmohne .shown in the patent crease the soft stock und leave a perceptible line between euch laterally adjao ut Series oli'rin'gs, this line being slightly raised. It is to overcome this dilliculty that an im iortant feature of this invention has beeny evised. ln accordance with this,V feature of the'ini'oniou the rings carried by one rod are arranged in staggered. relation to the rings carried b v the rods on either side whereby 'he rings on esuh rod obliterte the lines und heat down the ridges which may he left between the adjacent rings on the rod thai precedes it in the rotation of the heater. in the construction shown this result is obtained hy employing on euch alternate rod end ringo which nre one and onohnl Limes the width of the other rings. In the prnetienl use of this machine through an extended period. of time it developed that the turning action of the rings upon their rods :is thevrings strike the Work and swing liucku'ardly in gliding over it turned the rods in the flanges of the huh and flint the severe outward pull of the rings caused h v rentrifugul force tended to wear the end portions of the rods that are contined in the finngnt. Experiments in the choice of sniinhle motori-.ils reduced ihls zic-,tion somewhat. hui: the wear was Sufficient to wenken the rods in die course of time and render poseible an accident resulting from a rod giving; way While the beutel' was in. use and throwing the rings intothe room und poesihly against the operator. To overcome this wearing of the rods and remove linhility of Such an arfident I have provided novel means for preventing the rotation in this hesiter of the rods upon which the rings swing. This is accomplished hy cutting into the outer face of one or both of'liihe flanges of the hnbnn annular grooveextending in the sememirele ns the holes' in the flange vinto which the rods project. I have also formed in the ond of each rod a recess :ind in assembling; the heater the recess in the rods is arranged in alinement with he groove in the huh fifmge and a wire or hoop in luid in rhin ooniinuous groove und oonstitui'oe n key whit-h prevenir. turningi movement of the rods in lhe fianges. The key is confined in place hy an annuler plate thin; is attached to the outer face of the flange.

`The several features of the invention 1nioo cluding certain details of construction and combination of parts will appear in the following description of the machine. l

Figure 1 is e front elevation of the niachine; Fig. 2 is a side elevation, partly in section; Fig. 3' is un inverted plan view showing the action of the beater upon a. shoe sole.

The frame of the machine. supports n shaft 2 upon which is mounted a hub hm'- ing end flanges 4 in which are supported the end portions of rods 5 that carry rings G. The internal diameter oi the rings is substantially" largerl than the` rods so that the rings are held outward by centrifugal. force while the beater is rotating. This arrange ment allows the rings to strike the work by impact with` a gliding blow and after hering contacted with the work to swing back- 'ivardly around the rod as they glide over tbe work. This action will be clearly understood from Fig. 2 in which u rin0r is shown us havingr struck the` work nur as being turned lmckwardly about the. rod ns it continues its movement over the work. The rings ure adapted to more relatively to one another as they strike the work in order to adapt themselves, that is, to present` an tuling face eouforn'iil'ig to the contour of the work. In practice there is necessarily n little looscness or play between the-rings and their annular edges are slightly rounded as at 7 to avoid marking the stock. Upon soft stock such as the tempered soles olV turn shoes and some upper materinls this torination of the rings tends to leave lines or ridges. As herein shown, the end rings (il, on each lalternate rod ure one and one-hull' times the width of the'othcr rings tl'iereby producing' a. staggered relation of the rings on adjacent rods whereby the rings on one rod beat out and obliterate the lines or ridges left by the rings on the preceding` rod.

The rods 5 are shown as confined ugulnst endwise movement in holes or sockets in the right 'hand Harige or disk 4. At their left hand ends the rods project through an annular series ofholes in the [lange and :1re erich provided with a, transverse opening or slot. The flange' is formed with an annuler groove 10v iassing through the rod openings. In nsse'mb ing,r the beater the rods are arranged with their openings in alinement with 'the openings in the groovevund a wire or hoop 12 is 'placed in the groove in engagement with u wall or walls formed by the openingsin the rods. The wire 12 thus constitutes' n' continuous key, extending around thebeatcr nndpreventing enr-.h of the rods from turning in its bearing in the flange. For confining the wire in place and preventing A:my endwise moven'ientof the rodstoward the .leftn eo'vrplulte 14 is nttached by screws to the outer end faceof the left hand ange.. The cover plete preferably has holes located over the ends ot' the rods but of smaller diameter than the. rodsand through which the ends o'l the rods und the Wire 12 may be seen to determine. at any time ii the wire has been sheared ollI and any rod hns thus been 'lreed to turn in its bearings.

Obviously, the eonstrurtion uhieh is described for the lel't hand end nl' the beater may also be employed at the right hund end but tlis has not been louud to he neces sary.

rl`he described construction has proven suliieient to ln'erenl the turning el' the rods and the wear of the rod ends which would result fromr snrb turning and would in time weaken the rodfl so that they might Qjive way to the, powerful rentiing-.tl orre whirh they nre called upon to withstand in the, rotalion of the beater at the high speed :it 85 which it is driven in the r-oulnurrinl nulchines.
