fo all whom, it may concern:

'Be it known that we, HENRY LAWRENCE G LLINE and IRvINELIAsHoToHms, of the town of Granby, and ARCHI-BALD IVES GIL- LIES, of Sherbrooke, in. the Province ofQne; bee, Canada, have invented certain new anduseful I mprovei'nents in Metal-Forming Machines; and we do hereby declare thatthe following isa full, cleaizand exact des'cription'of.tl1e same.

, Heretofore in the manufacture of horse collar rims or like'frames for other purposes it has been necessary to form the said rims by'hand, and this, besides-requiring skilled labor, has taken considerable time.

Our invention relates to the type of metal forming machine set forth and claimed in our pending application, filed under Serial No.

' 11,557 on the 4th of April, 1900; and the objectthcreof is to provide an entire'lymecham icz'tlly-operated mechanism whereby a complete horse-collar rim or other like frames for other uses can be produced;

The invention may be said, briefly,'to consist of astationary'adjustable part of a contour to give the required shape to the article to be formed-and mechanically-operated trav- 'eling forming mechanismto travel around aiid in close proximity to the stationary part to coact therewith, and thereby form the complete article from a length of metal by en.- tirely mechanically operated means.

' As in the above-mentioned pending application we elect to set forth our invention as applied to a machine for the manufacture of the rims of horse-collars where z flanged tu- The traveling peak-forming mechanism of the present embodiment of our invention is operativelyconnected to the traveling portion of' the throat-formingmechanism and is conse- I uently actuatedtherebyand simultaneously. therewith, means being provided -to-a\ 1tomatically guide, said traveling peak-forming mechanism during the performance of its function. p as before mentioned, similar in every respect 11,557. For full comprehension, however,' of

racks, means for moving the racks, and means can he stitched to the body of the collar. The

stationary portion of this throat-forming mechanism consists of a circular block die \ided horizontally intoupper and lower parts 1 b and a, respectively, the edges of the adjoining' faces whereof are grooved tocon ointly IOO constitute a circumferential groove d, while the perimeter of the upper part b is beveled, as at e. The lower part c of this block has a concentric boring which is contracted at its lowerend to form a collar f and is supported upon a pin 9, set rigidly in the bed-plate A of the table 13 at about the middle of said bedplate. This pin 9 is ofsufficient length to provide a fulcrum for a-lpair of swinging arms h, to be hereinafter described, and a portion thereof projects-above said arms and is diminished to form a shoulder upon which the collar f of the part c rests and further diminished and screw-threaded to receive an annular nut 11. The upper end of this nut is formed with a pair of spanner-holesj, whereby it can be turned into or out of place by any approved form of spanner, (not shown,)

and the said screw-threaded portion of said pin is formed on diametrical opposite sides with a pair of keyways 70, while the portion of said lower part c of the stationary form-' ing-block which overhangs the ends of the swinging arms is supported upon a 'shogt standard Z, diminished at'both' ends and screw-threaded at its iower'end to takeinto a tapped boring in the table and into a 'borpart -b, a pair of ing in the under side of the said part c. The upper part b of this stationary formingblock is'carried upon the lower end of a rod m, sliding in a vertical tube a, secured rigidly at its upper end to the eeiling,and slotted, as at 0, near its upper end, in which a pulley p is mounted. The interior of this tube has its lower end enlarged in diameter, as at p,

. and a keyway g extends longitudinally thereof from said enlargementfor adistance within the tube greater than the length of the rod m, while saidrod has a key'rnear the upper end thereof to, under certain conditions, take into said keyway and retain said'rod against rotation and under other conditions to be loeated in the said enlargement p to allow of the rotation of said rod, aswill b'e'presently pointed out.. pins 3, projecting from its underside to take into borings in th'e'nppe and is forming-block are separated-being supported upon said sleeve u. This disk s has a series of perforations 4'with diminished upper ends,

' in which a re carried a series ofthumb-se'rews 5, having transverse pins against con'iplete withdrawal'from "the said.

disk, while the upper face "of the: part b of the stationary forming-block has aseries of tapped borings into which said screws take.

The interior of the sleeve it has a pair of keys 7 with thei-rinner facesscrew-threaded, and ahandle 8 is keyed upoi the .ro'dm a. short distance above the'disk s, where it is held against upward displacement by a pair Thisnpper 'partb of the .sta: tionary forming-block has a series of dowelr side of .the part c,

connectedto the lifting-rod m bya disk s, centrally perforated to take over the 6 to retain. them" ofjam-nuts 9,-taking upon the rod, which is screw-threaded at that point. Between this handle 8 and the disk 3 is located a circular box 10, also keyed to the rod m and resting upon a washer 11, which in turn rests upon the top of the disk. A retractile helical spring 12 is located within said box and has its ends taking, respectively, into a perforation in the inside of the top thereof and in the disk s, while a rope 13 is connected to an eye 14 in the top of said rod and taken upwardly through the tube n and over a pair of suitablymounted pulleys p and 16 and has a weight 17 at its end. to counterbalance and lift said rod and all the parts connected thereto when the sleeve to is free of the ping.

To secure thepart b firmly in place, the sleeve u is inserted in the central opening until the partsb and ccome into contact with one another. The handle 8 is then moved srew-thread's'upon the interior of the keys 7 and the screw-threaded portion of the pin g,

and retaining them in place, and the reverse action willdisengage the parts from one another and allow the weight to raise the upper rigid stops 18, carried by the disk s, limiting the movement of the handle 8 in either direction. I

To enable the semicircular blocks 23 to be adjusted toward or'away from the stationary block b c to accommodate different diameters of tube from which the rims are made, we provide. means for adjusting the slides 21. adjusting means-is the same consists of a-ratchet-bar 29, resting loosely in a slot in the underside of the slide and upon the top of the swinging arm. The outer end of this ratchet-bar is rotatably connected-to the inner end of a thumb-screw'30, taking through artaper ed'boringv in the vertical portionof the "bracket 2-1. To enable these semiclose engagement with the {rim metal, which is inserted between them and'the stationary .throat-bloek,-.as will be presently shown, a hen-crank lever 31 is fulcrumed in a block 32,

carried rigidly i'n each's'lide. tar-m oft-this bell-crank lever is elongated and formed with a handle '33, andthe end of the other arm has a'pawl 34 pivotally connected of the ratchet-barj29. to hold the rim metal in place when it is first inserted between the-stationary and movable par-ts of the throat forming mechanism, and consists :of a flat. i-ng'one endp'iece and formed with its end to fit over- ,37 secured rigidly; thereto spending in-angle tothe beveled upper porto fit agaihstthe flange of the'rim metal and of which takes through the middle perforathereby through the connection between the circular blocks to he moved and" locked into The end 'of' one thereto and rests-in engagement with the teeth.

A clamp isprovided bar 36, set on edge and ha-va semicircular recess 38 atthe tubular portion f-- the rim metal, and a beveled portion 3-9, corretion b of the stationary throat-forming block,

having a 'pair of dowel-plns-40, theupperone drawing said parts I) and c firmly together This for each slide and longitudinally within said boring 74 and is, connected by a'pin 77 to the-hub ofa gland 78, movable by-means of said rod into en- 70 tion in the i'lange and the lower end into a guiding-perforation in the lower portion of said stationary throat-forming block. This bar 36 is .forced into tight engagement with the rim metal to secureit firmly in place upon the stationary block-b c-by the following.

means: The outer end of the bar is thickened and-forme'dwith a guideway '41, in-which an adjustable raichet-lba'rf42 is supported by a pair of screws-4. 3,takingdowuwardly through,

slots-43 in saidibarand intov screw-threaded perforations in said ratchet bar. The outerend of the ratchet-bar has a tapped boring, therein, into which takes the end ofa screw 44, rotatably mounted, but held against lon gitudinal movement, in a bracket projection- 45 upon the u nderside of said ratchet-bar and constituting the end ofthe guideway 41-.-- A- bell-crank lever-is fulcrumed upon a spindle 46, carried in vertically-arranged bearing- 'plates 47 uponthe bed-plate of the machine. Theseibearing-plates are braced together at their'upper endsby a covertin the form of aplate. 4:8, secured'in place byscrews'. One

- arm 49 of th e'bell-crank-leve r is elongated and.

weighted, andithe other arm 50 thereof has a pawl 51 pivotally connected thereto and kept yieldingly in engagement with said ratchetbar by abow-spring 52, while a handle 53' is secured upon one end of said spindle'46, and

a handle 5; is secured rigidly upon the outer end 0f.the' barr36.. v

Th'ei'arms h. are caused v fulcrum-pin g by means of .a pair of quad-' rantal'racks 55 of T cross-sectiomset in'a circularguidewayefi, also of T cross-section,. in the bed-plate. Half of this-guide wayis.

covered .by a semicircular plate 57, secured: in place by screws 58, and the other half is. partially covered by a pair of semicircular.

strips 59 to retain the racks 55 against verticaldisplacementand accommodate a ver-' tical bracket-piece 60, formed integrally with one' end of eachquadrantal rack 55 and rig idly conhectedjto the outer "ends of thearm's h by screws 61 These racks aremoved in, opposite directions in their guideway 36 by a pair of. bevel-gears 62, rigidly mounted upon a shaft 63, arranged transversely ofjthel pmachine and mounted at each end in bearings 64, supported upon brackets 65, hung from the under side of the bed-plate andabout midway ofits length in a bearing secured also upon the under side of the bed-plate, worm-wheel 67 is mounted rigidly upon the' transverse shaft and intermeshes with a worm 68,1'igidly upon a main driving-shaft 69,:bearing adjacent to said worm in bearings 70, supported in a hanging bracket 71, bolted tothe under side of thebed-plate and at one end in ".a bearing .72, supported in a hanging bracket 73', bolted' fto' the under side of the bed-plate near the front thereof, This shaft 69 is bored, 'as at 74,]Ongitudinally from its forward end to a pointfabout midway between said brackets 71 aiidITQ'an'd-is transversely slotted, as at, 75. A rod 176 takesinto and is movable pulleys 79 andSO. toswing upon the gagement with-the friction-faces either of a 'pair of oppositely-driven loose pulleys 79 and 80. A small adj ustable screw-bolt 81 takes intoa tapped boring'in the inner end of .oneof the racks 55 and held againstinward mov'eim'ent by a jam-nut 82, and this inner end of the said rack acts through .bolt 81 upon a slide connected on its undersidetb means to be now described for shifting "said-rod 76.

throat portion of the before=mentioned application filed on the 4th day of April, 1900, un

. derfierial No. 11,557.

. The stationary peak-forming block which 2 5 forms a part of slhe present embodiment of- 40 rated lugs 117- to take into the space between said bearing portion 114 "and through which said'pin 115 takes. These adjustable parts 116, as is. evident, serve to mask the frame 110 and presentmatrix-facesto coactwith a 5 pair of" traveling blocks to be hereinafter described to-foriii the peak. The joint exterior of these two maskingparts 116 is of a contour to impart the required shape to the peak of the rim, and said exterior is grooved, as at I22; in a line at its endadjacent to the traveling forming-block with the groove upon the periphery 6f the said stationary throatforming block, and this groove 122 is curved u pwardly' from its end adjacent to the throat-block formed in the exterior of said masking parts along the'upper'edges thereof and along the loweredges of thegrooves 122. The spaces between the nppe'r edges of the groves 122and the Go upper keyways are fiat to provide surfaces 119 to shape the flange of the rim. These masking parts 116 are adjfi'stable (to enablepeaks or rims of difierent sizes to be made) by a slidin g block 123, set in a T-groove formed in the? 6 5 inside of each of said parts, said sliding blocks being each formed with a transverse slot 124:- of almost circular cross-section, into each of bolt 126. These screw-bolts take into the opposite ends, which are oppositely screwthreaded, of a sleeve 127, fornied with a wormof and set in a transverse horizontal boring in the wb of the frame-piece 110, wherein it 129, held in place by a retaining-screw 130.

on, is set in avertical boring in the said web and the upperend of this spindle 131is formed date which the trimmer-bracket 135, to be presently described, has an opening 136. The space between the adjacent ends of the parts -.116 is filled by a dovetailed piece 137, interchangeable with other similar pieces of difor diminished by the adjustment of the said parts 116. Thetraveling mechanism of the peak-forming means-to coactwith this expan one end of each open and the side thereof facing the stationaryformi-ng-block formed with bayonet-keys 137 to take into and slide along the keyways 118. The side of each of these hasa socket 140 upon the center thereof, into which takes a ball 141, which constitutes, with the socket 140, a ball-and-socket joint, the ball being formed upon one end of each of a pair of rods 142, the opposite ends whereof ing arms h. these-boxes and is adjusted therein toward and from the side adjacent to the stationary formingblock by. means of a screw 145,

and connected at one end by a ball-and.- socket joint 146 to said block, while the outer end thereof is furnished with an adj ustment-- handle 14?. A pair of jain-- nuts 148take the function thereof is to set the 'predeter mined distance it is necessary to adjust the block 14-1; Eachof said adjustable blocks 144 carries an antifriction-roller 151, mou n ted therein, diagonally thereof, upon a spindle 155, and a bearing-block 156, rigidlysct therein at right angles to the outer face thereof.

to The outer edge of this block and the (302i! plete its rear end, while a pair of keyways 118 are" edge of the roller are grooved to correspond to and register with the groove in the stationary peak-forming block. A pair ol'counterbalancing weights 157 are connected by cords 159 to the boxes l-ZU to prevent their faliing rto the table after leaving thegrooves 122, as will be presently pointed out. this peak-forming mehaniSm-that is to say, the stationarypeak-forming block and the traveling formi ng-hloeksis adj usl-ed toward or from the throat-forming mechanism to. en-

able rims of diiierent lengths in be made by va bell-crank lever LS4, filltil'likic l, as at 185,

with a square socket 133 to receive the squared end of a removable crank 134, to accommo-' ferent sizes to fill this space as it is increased sible block consists of a pair of boxes 120,with

threaded through the opposite side of the box upon this screw 145, outside of its box, and

to the under side of the bed-plate of the chine, and the end of one arm i-hereotbein'g'i slotted, as atjl86, and the end of the other arm '1 being forked,-as at 187. The slotted end 186 takes over the lower end of a pin -188,car-

ried 'rigidly'in the peak-block, as will be presently desci-ibed,- and the forked end 187' has an interiorly-screiv-threaded sleeve194, pivotallyinoilnted between the prongs thereof. A screw-threaded spindle 195 takes'into this pivoted sleeve and is rotatably mounted in a bracket 196 upon the under side ofthe bed-plate, but-retained against longitudinal.

displacement therein, and the outer end of,

this screw-threaded spindle hasacrank-handle 197 rigidiy mounted thereon; The pin 188 is diminished at its upper and lower ends and screw-threaded at its npper-end' and takcsthrough a. horingl89, extending through the peak-block frame and increased in diame ter at both ends to accommodate at its lower increasedend the enlarged portion of the pin 188 and at its upper increased end an expa'n silo-coiled spring 190. The upper end of this pin 188, projects above the top of the peakblock frame 110 and through a bracket forretaining-the masking parts 116 of the stationary peak against displacement and receives-a not 191, which serves to secure the pin rigidly in the said frame-piece 110 of the peak-block and said bracket 135 rigidly upon "the top of the web of said framepiece andthe masking-pieces, thereby'securing all of said parts rigidly together. The under side of this bracket is formed with a tongue and the upper face of the web with a groove to receive said tongue and retain the bracket when the not 191 is tightened against lateraldisplacement.

By turning this crank liaudle the normally stationary peak-forming block and all the parts connected thereto can be ad-' .j usted toward or away from, the th roat-forming mechanism to enable, rims oi different lengths to he made.-

The bracket 71 besides servingasa sup port for the shaft-bearings serves also as a recept-acle to catch the lubricant dripping from 'the worm, worm-wheel and the bearings 70, froin which receptacle it can be drawn 0E by .the drip-cock 230 and again utilized.

.-The operation of our machine is as follows:

-' The length of flanged tubular metal is first set in placehetween. the stationary and traveling lparts ofi the throat-formiug-inechanisin and with the;ini-ddlefperforatrimi G of the flange of said tubular-"length in line with the clamping-ban This bar is then jammed by its leverinto tight contact with the flange of the, rim n' etal, and withthgspinon the end of said clam ping-bar projecting'th'rougli the said middle perforation in the flange intoa hole in the upper portion of the throat-block. The

semieircularfthroatforming blocksare then moved by their levers into bearing relation with the rim metal. therebybending the'middie portion oi the flange to extend at atangent from the tube. Upon the n'iachinebeit is pushed out of the ends of its i'ng then started, said semicircular blocks will f'oll the rimmetal upon the stati nary throat- .forniing block for slightly more than onehalf of the circumference of saidblock, at

'wh ic hv point the machine will be automatically stopped, therebyleaving the ends of said rim metal projecting on each side of the stationary peak-forming block. pawls for locking thesemicireular blocks are then released and the-machine reversed,when it will return to its normal position and be antomatically stopped. One of the boxes 120 is then set in place wiih iiskeys 237 in the keyways at one side of the stationary peakforming block, and the hearing parts in said box are adjusted by the adjustment-handle into bearing relation with the rim metal The machine is then again started, and after the arms have moved a short distance the free end of the rod is lifted into and borne upon by the socket 143 of the adjacent swinging arm, and the said box is pushed along the full length of said keyways andout of the oppo- 0 site ends thereof, thereby impressing the rim metal upon the stationary peak-forming block, and imparting thereto theform necessary to the rim of a collar bent at its peak. \Vhen thistraveling' forming mechanism reaches the limit-of its travel, the machine will, as before mentioned in the first cycle of opera- '.tion, be automatically stopped, and when reversed the ar .will return to their normal positions and the machine be again auto- I00 inatieally stopped. The other box is then se in place and the' above operation repeated to form the other side of the peak, the side just formed of the peak being sprung upward at its end to accommodate this other box 4 keywaysf.
