To all 'whom-15 mag/concern: Y

Be it known that I, CHARLES H. How- LAND-SHEARMAN, a citizen of the United States, residing at Indianapolis, Vin theV My invention relates to improvements in machinery for automatically manufacturing brooms such as shall be adapted to supplant the prevailing methods of manual manufacture, and itsparticular, objects are:

` First, to supply a broom press capable of automatically bringing together broom corn, or similar materials, when cut to proper lengths and` fed into said machine, so as to form the shoulder of the broom,

ready for sewing to complete same for the v broom; second, to supply a broom press particularly adapted to collect together brooms of that style of mechanically made brooms havingdetachable handles, such bringing together of said brooms being completed by the press before any handles are applied to same; third, to provide a broompress mechanism adapted to automatically apply upon'the broom materials a ring which shall serve to constrain the same in a state of high compression, instead of the previous methods by binding the material by wire upon handles as in manual manufacture, or

-by rigidly 'clamping the same between riveting clamps or screwed retaining members as in .mechanical manufacture; fourth, to provide a broom press embodying automatic mechanisms adapted to respectively receive the `rings for the quantity of broom corn and secure each-bunchV of broom cornA together in the press, a'mechanisin adapted to receive individual chargesof broom material for making the individual brooms of uniform size, and mechanism` adapted to I attain the objects stated by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my broom press; Fig. 2 is a top plan view of same; Fig. 3 is an enlarged detail of the clutch 'release mechanism near the rear end of the clutch shaft; Fig. 4 is anl enlarged detail of the forward end of the same clutch mechanism; Fig. 5 is an end elevation of the broom press showing the relative position of the motor, power gears, crankshaft'and crank; Fig. 6 is an enlarged detail taken partly in section showing the man-ner in which the rear section of the crankshaft is journaled in a bearing in the rear end of the intermediate section thereof; Fig. 7 is atop plan view of the compacter mechanism; Fig. 8 is a transverse section, vtaken onfthe line 8-8 of Fig. 2 looking in the direction of the arrows, showing the automatic broom corn feeding mechanisms, ring feeding mechanism, jaw mechanism and broom corn stripping and conveying mechanisms, with the contact mechanism of the power clutch; Fig. 9 is an enlarged top plan view of one ofthe larger sizes of dies adapted to be interchangeably used instead of the smaller size of die shown in Fig. 2; Fig.

15 is an enlarged partly sectional elevation of the straw inserter roll crank, taken on enlarged detail, partly in transverse section and partly in elevation taken on the line 16-16 of Fig. l, showing the press frame,

the `linel-l of Fig.V 1; and Fig. 16 is an and pins in operative position, on the line Similar numerals refer to similar parts throughout the several views.

Referring to Figs. 1, 2 and 5, 1 is the 1e` press frame, which is supported on legs 2,

3 and 4, and having securely mounted thereon the motor 5, the axle 6, which bears on its front end the motor pinion 7, preferably of the noiseless liber type. Said motor pinion meshes with the intermediate gear 8,

on the intermediate shaft 9, which is journaled in the front pedestal 10 and rear pedestal 11 superiorly secured upon the table 12 of said press frame 1. A set collar 13 prevents rearward endwise motion of said intermediate shaft 9 and forward endwise motion of same is prevented by the intermediate pinion 14, keyed thereon, and cheeking against said rear pedestal 11, said intermediate pinion being also preferably of a noiseless 4fiber construction. The flywheel 15 is keyed upon the eXtreme rear end of the intermediate shaft 9, for the purpose of placing intermediate to said flywheel and the intermediate gear 8 the high pressure delivery torque of the intermediate pinion 14, found by experience to be indispensable for the successful operation of my invention. r The intermediate pinion 14 meshes with the crank gear 16 journaled on the rear section 17 of the crankshaft, of which the rear end turns in the rear yoke pedestal 18 of the rear yoke 19, supported on the leg 2, and the forward end of which, as especially shown in Fig. 6, is provided with a reducing 'y forward end in the crank-pedestal 28, beth f ate-11u29 of `the l 0 t s j -i iwhichyis' jointedt 555.`

and a tension spring 41 respectively secured to said leg 2 and said clutch lever 30 causes the latter to normally throw the movable clutch disk 26 into engagement with the fixed clutch disk 23.

Referring to Figs. 1, 2 and 5, the set collar 42 secured upon the intermediate section 22 of the crankshaft and cheeked against the crank pedestal 26 prevent-s longitudinal movement of said intermediate section in onedirection while the crank disk 43 keyed upon the forward end of said intermediate section and checking upon the front fac-e of said pedestal prevents longitudinal nieveinent of shaft-section 22 in the opposite directien.` `Said inner crank disk 43 is united to the outer crank disk 44 by the nkpin 45 respectively secured thereto by .he nuts 46 fand 47, so as to give a perfectly firm bearing for the crank link 48. rilhe outer crank disk 44 is keyed upon the cuter section`49 Of the crankshaft which is jiournaied in the brake pedestal 50 borne on the front yoke 51 of the leg 2 and the front end of sa id section 49 has keyed thereonthe friction brake 52, the function of Iwhich vent the crankshaft parts from inofr l inertia beyond the peint to which tl are .carried by the power after 1 1 nection of the clutch disks. The crank link 48 has provided thereon the fork wl is articulated by the cross head pin 54 to the tang 55 of the power cross head 56. Said power cross head 56 is pref `-Iably made as shown in the views referred te, in the form of an ordinary piece of shaft-in adapted to slide smoothly in the bored ackets 57 and 58 secured upon the table 12 of the frame f1.

The cross head collar 59 is rigidly secured upon said power cross head o6 and bears dependently secured to its. nder side the cam bolt 60, attached to and supporting one end ofthe wedge plate 61. the opposite end of which is attached to and supported by the wedge bracket 62, also rigidly secured to said cross head 56. The trunnion block 63 slides freely upon the power crossheadv 56 but iskep't from turning laterally thereon by the feather 64 secured in said power cross head which also slidablyfengages with the bored bracket 58.

outer arin of the crank-arm and tothe inner fork 71 of the synchronizing` link 72. Said inner crank-arm 70 is journaled upon a pivot-pin 7 3 to a bracket 74 secured to frame 1 and j its outer arm projects through the inner opening 7 6 leadiinel from the inside to the outside of said frame, especially shown by Fig'. 2. The outer arm ofV saidsynchronizing` link 72 is jointed by the pin 77 to the out-er end of crank-arm 78, the outer arm ofV which likewise makes egressrthrough an opening 7 9 in the frame. It will Ybe clear from Fig'. 2 that the` inner crank arm 70 is greater than a rightiangle, but that the outer crank arm 78 isV correspondingly less than right angle, in order that the simultaneous actuation of the cranlnarms in the direction of the arrow by the synchronizinglink 72 shall operate them equally, but in opposite directions, both toward common center. Said outer crank arm 78 is journaled upon the outer pivot pin 80 arranged in bracket 81, secured to frame 1. The inner end of said inner crank arm v70 is jointed by the inner knuckle pin 82 to the inner straight link 83, the inner end of which is in turn jointed by the inner thrust pin 84 to the inner thrust block 85, secured upon the inner die block 86 sliding in the ways 87 within which it is secured by the cap plates 88, tbc inner end of the outer crank arin 7 8 is jointed by the outer knuckle pin 89 to the outer straight link 90, the inner end of which isv jointed by the outer thrust pin 91 to the outer thrust. block 92 secured to the outer die block 93 running in the Ways 9a within which it is held by the cap plates 95.

Referring` to Fig. 2, in connection with Figs. 9 and 10, the several sizesof dies, 96, used by me in my broom press to form brooms for the respective trade-sizes of brooms all lit interchangeably in the respective die blocks 86 and 98, so that Vsaid dies face eachother with their` broom form-ingr configurations registering oppositely as cach of said die blocks is driven Vtoward the opposite die block when the respective opposing toggles thereto attached are simultaneously actuated Said dies are and are held securely upon their seats'by die bars screwed to' said die blocks, as 98, (.lppositely renisterinnv rinp' slots 99 are provided in said die blocks, ada d to admit the broom rin gsvfhich, upon en `ri ance therebetween, drop behind the abutment shoulders 100 upon the ring ledges 101, upon which they aresecurelv held by the springs 102 secured by screws10., to the die. j Als sai-cl die blocks 88and98 are brouobt ton ,i her with an oval rino;` (as 104;, Fini'. 8) field upon said ledges between said dies, Vthe ring is first flattened along' the straipght faces 104'ci and then given Vthe final curved ends of the Yhand lover housing),1 1,13.

by the foiining curves 105, 106, formed upon the interior edges of the tool steel die-, liners 107, 108, secured at'either end of the die body 109, so as to give the resultant conipressed brush a rounded'oblongcross section at the point at which the ring,y is coinpressed upon same. The exterior edges of said dier- liners 107, 108 have angular faces 110,- 111 preferably of 1-5 degrees angularity for accommodating between saine the corresponding' angular faces of the tool steel abut- `ment blocks 220,l 222, which receive the thrust of the eXtreme ends'of the ring, form# l ino' tangente to said curves 105, 106, as the dies close, as will be clear frdoin Fig. 2.

s shown in Figs-1 and 2, the parts of my broom press are arranged for the proper .crank throw and stroke conditions to make a given standard size of brooms, but when it is desired to make a different standard ed, will properly forni the altered size of broom required. This provision for adapting` my press to various sizes of brooms is one of much practical importance and has been proved by eXperience upon actual inachines to be quickly and reliably operative in its results.

Referring' to Figs. 1, 2 and 8, the hand lever housing 118,` issecured upon the front of the frame in line with the central transverse axis of the toggle mechanism, and infcloses'the several elements which control the presss entire operation. The hand lerer 114 is mounted in the bracket 115 upon the fulcrum 116, which is provided at its top with handle 117 for fijoverning the press operation.

When the broom materials are admitted through the chute 118, supported by the circular frame 119, secured to the boss 120 on the broom ring; chamber 121, they drop through the compacter upon the resilient table 1:23 of the floor plate 124, provided with ears 125 through which the pin 12b is. jointed to the floor plate link 127, in turn jointed by the pin 128 to the vertical arni oit' the floor plate bell crank 129, which is j ournaled upon the fulcruin pin 130 in the bracl-:et 131 made integrally upon the floor The short arm of said floor plate bell crank 129 has Vfixed therein the `pin 182 adapted to engage the closed slot in the slot link 184, the

lower end o'twhich is jointed by the pin 185 to the curved crank-arm 136 of said hand lever 114, the forked short arm 137 of which is jointed by the pin 138 to the ring feed bar 139, used for actuating my ring feed mechanism as hereinafter' described. The hand lever housing 113 is provided with a central transverse aperture 140 through which the members 134, 136 and 137 operate with free clearance. r1`he chute 118 shown in Fig. 8 and in slightly modified form in 10 Fig. 12 is adapted to admit the broom materials for proper alinement upon the floor plate 124, prior to compaction of same with 1n the broom ring. Said chute may be elongated to any desired height, so as to permit nl5 the broom materials to acquire. sufficient gravitational momentum for their ready alinement upon impact, or it may be shortened if it be desired to insert the materials manually in individual broom charges through said chute and thus aline them upon the floor plate, or the chute 118 may be constructed with any desired number of internal apertures as shown by 141 Fig. 12 for the purpose of keeping separate tbe correspending kinds of material employed in making the broom, this formation of the chute being used when manufacturing brooms of the type having fine hurl covering over coarser interior iillers. Fig.' 14

details the construction of one of my standard forms of floor plate, in which the resilient table 123 is supported on springs 142, which keepl its flanges 143, 144 normally pressed up against the retaining flanges 145,

35. 146'so that Said resilient table shall be flush with the top of the plate, and said springs 142 are retained lat the base by the tool steel slide plate 147 secured by screws 148 to the floor plate 124, air apertures 149 being supplied to permit free passage of the airin the rise and fall of said resilient table 123. I' frequently employ large sections of very open-pored rubber Sponges in the cabinet 150 of the floor plate, for resiliently supporting said table 123 instead of the springs 142, both constructions being successful in operation. The function of the resilient table 123 is to yield sufficiently upon impact of the broom materials, when gravitated sharply upon the floor plate, so that upon the rebound of said member 123 it automatically alines any bers which may have lfallen in .advance of other fibers ofi the frlfn'oom. i This `function has been proven by flink 152, in turn jointed by the pin 153 to the compacter slide 154, sliding'in the guide formed integrally in. the top 'of the `hand lever housing113, and a pin 156 joints to fsaidfslide' the ratchet hook 157, adapted to @156,15engage'V the ratchet j 158 on the compacter yoke 159, secured upon the front ends of the wedge- rods 160, 161, by which the compacter is actuated as below explained. rlhe compacter 122 is made as a hollow rectangular frame provided with crossbars 162, 163, secured to either side thereof, for the purpose of. sustaining the central mechanism of said compacter. Four quadrangularly disposed bosses 164 on the compacter frame are adapted to receive the upper ends of the compacter rods 165, secured to the compacter by nuts 166. Long wedges 167, 168, engagedly sliding upon the respective guides 169, 170, at either end of the compacter frame, are secured at the in ner ends of the wedge- rods 160, 161, and compression springs 171, 172 surrounding the rods 160 and 161 tend to normally push rearward said wedges 167, 168, and thus withdraw toward the compacter frame the compacter yoke 159 when the compacter is opening for reception of broom materials. After the reception of broom materials, the actuation of the handle 117 withdraws said compacter yoke 159, compressing said springs 171, 172, and causes said long wedges 167, 168 to push inward the short wedges 173, 174, secured on the outer ends of the plunger bolts 175, 17 6, sliding in the plunger sockets 177, 178. Each of said plunger bolts is provided with a collar as shown at 179, Fig. 7, and encircled by a compression spring 180, impinging against the fixed sleeve 181 secured within the inner end of the socket, thus keeping each plunger bolt, as 17 5, with its small wedge, as 173, normally pressed outward against its respective long wedge, as shown, Fig. 7. Each of said plunger bolts is also pierced by a slot 182 engaging the pin 183 driven through said fixed sleeve 181, which prevents the plunger bolt from turning. On the inner ends of the respective plunger bolts 175 and 176, vertical pins 184 and 185 are provided upon which are jointed the two sets of curved interlapping compacter lingers 186 and 187 on said pin 184 and 188 and 189 on said pin 185, the internal coniiguration of all of said four compacter lingers being so curved that when the compacter shall be compressed upon theV broom materials, the ngers will take the position shown in Fig. 7 and combine to form an inclosed space` between them,` corresponding tothe oval contour of.` the broomjring held in the die blocks below", as f shown at 104,

Figa` 8, through which the compactedina- `terials are to be-passed. `The'inner*end `of `each of the compacter lingers isprovided wwithfa roll as y190', turning onj ai pin as 191, i .which rolls face each other' `and impinge upon' the sides ofthe wedges 192,1securedly imposed onthetop of each vof the plunger bolt sockets as `,17 8, with the resultthat, as each of the small wedges 173, 174 is forced inward by the long wedges 167 and 168, the

outer ends of the said Acompacter fingersv through such la broom ringas 104 Figq8.`

Tubular spring j return- members 193, 194, hingedly jointed uponsp'ring arms as 195, secured on the outer ends of each of said compacter `lingers, draw said outer ends together and keep theV rolls as 190 in constant contact upon the wedge 192, when'the inward motion of the compacter yoke permits the plunger bolts 175 and 176 to ily out` ward, and thus the iingers of the compacter open for the reception of anotherl charge. Detent bars 196, 197 each providedwith duplex spring bolts 198, 199normally press down the respective detent pins 200, 201, so that the same shall engagein suitable holes in the respective campacter rods 160, 161 tol hold the compacter mechanism locked in its compacted position as in Fig. 7 during Vin sertion of the broom materials through the broom ring, but, upon the compacter being drawn down to the bottom of its vertical `stroke by the compacter rods 165, said spring bolts- 198, 199 are forced upward vby lcontact with the upper side of the frame" 1, as indicated in Fig. `1, thereby simultaneously releasing bothV detent bolts 200 and 201, which permits the compacter yoke 159 to recede toward the frame 'and all parts of 'the compacter to return to theiropen positions for receiving another charge.

The preferred form of my invention, in which a compacter of the typeof compacter 122 is employed, embodieswhat l term a broom corn inserter linkage, for the purpose.` of drawing down said-compacter 122 after the compaction of each charge of `materials andinserting the same -through the ring which is to be compressed thereon.

This mechanism is clearly shown inFigsj 1, 2, 15 and 16, in lwhich 202 is 'the roll crank brackets, inferiorly secured to the frame 1 and bearing therein the fulcrum pin 203, upon which are journaled the paired roll cranks 204 and 20,5,.{betweenthe shorter crank arms of which is journaled upon the pin 206 cam roll 207 adapted to be actuated by the wedge cam` 208 of thel wedge plate 61, Athe cranks having secured between them the adjusting yoke 209 pierced by the lock-nutted adjusting4 bolt 210, dependently sustaining the slide yoke 211, provided with four lateral ears, as 21,2, Fig. 15, on the front and back thereof, embracing the smooth slides 213, along which the position of said slide yoke is variably fiXed by said adjusting bolt, to Vregulate the motion imparted-from the roll crank. The pin 214 in the` slide yoke 211 joints the same to one end of the broom corn inserter link 215, the opposite end of which is jointed by the pin 216 to the forked rock lever 217, secured upon the rockshaft 218, journaled in the brackets 219, 21921, dependently secured to either side of theframe 1. Paired rock links 221, 221"L are securednext to either of said . brackets 219, 219a upon the `rockshaft 218,

and, as especially indicated in Figs. 8 and 16, are jointed bythe pins 223 to the duple compacter links 224, which are in turn jointed by the pins 225 to the compacter bases, as 226 Fig. 8, from which latter view the rear of the said compacterbases, with its links, has been broken away for clearness in drafting. lThe weight of the compacter is balanced by the counterpoise 227, the arm 228 of which is rigidly secured upon the rockshaft 218. The latter has secured upon its eXtreme rear. end the spring lever 229, jointed at its topby the pin 230 to the forked spring rod 231, ridingin. the spring bracket 232 and provided with strong compression springs 233, held under compression against said spring bracket 232 `by the spring cap 234. The function of said spring rod and spring lever is to accelerate the upward return of the compacter 122 after it has deposited each the pin 235 to the forked short arm'236 of the duplex release lever 237, the two sides of which embrace the interstitial ring feed lever 238, commonly fulcrumed with said release lever on thepin 239 in the fork 240 of the ring` feed bracket 241. rllhe top of the ring feed lever 238 is Vj ointed by the pin 242 to the plate link 243, in turn hingedby the rod 244 to the clamp 245 within which is secured the ring feed plate 246, provided Vat its inner end with a curved jaw 247,

having a contour adapted to fit the exterior of the oval rings 104, and of a thickness equal to one only of said rings, so that upon recedence of said ring feed plate 246, one ring only from the gravitating pile of rings in the ring feed chamber 121 shall enter and fill the jaw of said ring feed plate. On either end of the rod 244 are secured brackets 248 and 249 through which telescope the guide` rods 250, 251, secured to the frame 1, encircled by springs 252 and 253, which nor mally tend to throw outward the ring feed plate 246 whenever the lever 238 is released. Said ring feed plate 246 rides upon the hardened steel base 254 and is inclosed within the U-shaped cap plate 255, resting upon said base. Cap-plate 255 is providedv with an aperture through which the broom rings are fed from chamber121, and said cap is provided in its lower or under surface with a channel 256 forming a passageway for the rings in their movement toward the dies.

The duplex release lever 237 is provided with brackets 257 upon the pin 258 on which is ifulcrumed the release crank 259, provided with a fork 260 engaging interiorly the collar 261 and eXteriorly the crown 262 of the acorn bolt 263, which is normally kept in engagement with the socket 2611 of said ring feed lever 238 by the spring 265 c0mpressed between the release crank 257 and the lug 266. l/ihen the action of the hand lever 114, through the ring 'eed bar 139 throws vforward the ring l'eed lever 238, the release crank 259 makes contact with the release bolt 267, secured in the ring feed bracket 241, thus withdrawing the acorn bolt 263 'from the socket 26l in said ring eed lever 238 and permitting said bolt to ride idle over the tace of the arc 268, which extends integrally flush with the face of said ring reed lever 238 and the latter, being thereby released, `is instantly forced backward by the springs 252 and 253 to admit another ring 104- to the mouth 247 of the ring leed plate 2fl6, while the release lever 237 remains in its forward position until released by a return stroke of the handle 117.

Referring to Figs. 2, 3, l. and 8, the bracket 2e9`bears an integrally dependent lug 269, in which is secured the tappet screw 270, adapted, upon Yforward motion of the hand lever 114, to contactively actuate the rock link 271, secured upon the upper end olf the rockshaft 272 turning in the vertical boss 273 integral upon the ring Vfeed bracket 2l1. Upon the bottom end oi said rockshatt is secured by the nut 275 the rock lever 276, the forked ond 277 of `which engages by the pin 278 with the release hook 279, the opposite end or' which engages with the clutch release link 280 journaled on the clutch shaft 39 and normally kept thrown behind the clutch release crank 281 turning upon the tulcrum 282 secured to the under side Vot' the frame 1, as shown in Fig. 2 by the action oii the barrel spring 283, surroundingesaid clutch shaft and impinging against the collar 284 secured thereon, but capable of being withdrawn from engagen'ient with said clutch release crank 281 by contact of said `tappet screw 270 with said rock link 271,`

thus giving the parts the position shown in Fig. 3, in which position the power clutch disk 23 is in engagement with the clutch disk 26, thus placing the press into full operation. The hub oi' said clutch release link 280 is bored to lit the clutch shaft 39 and is engaged by the feather 285 secured in said clutch shaft. The motion of the said release link 280 is limited by the collar 286 also secured to said clutch shaft. The release crank 281 is actuated by the thrust thereonwf the vertical release bar 287 dependently secured on the die block 93, with which release bar said crank is constantly kept in contact by the tension spring 288, secured between said bar and crank, as clearly shown inF ig. 3.v

rit the completion of each broom compressing cycle of my press, as the jaws open, said release bar, acting through its thrust upon said release crank and thereby actuating through the release link 280, the clutch shaft 39, disengages and holds in disengagement the clutch 26 from the clutch disk 23, until another operation of the hand lever 114 shall have caused the rengagement of the clutch by action ot said tappet 270 upon said rock link 271.V The manner in which the clutch disks are automatically engaged j by the clutch lever 30 upon release of the said clutch shaft 39 is clearly stated in lines to 70 page 2.

Ejecting and conveying mechanism is indicated by Figs. 1 and 2 and partly depicted in enlarged detail by Fig; 13. lThe ejector bolt bracket 289 is secured upon the die block 86 and is jointed by the pin 290 to the ejector bolt 291 sliding in the socket link 292 and adapted to contactively engageV the spring bolt 293, normally caused to protrude transversely within said socket link 292 by action oi. the compression spring 29-1- beneath the collar 295. is jointed by the pin 296 to the ejector crank 297, journaled on the ulcrum 298 of the ejector bracket `299, the long arm of which is jointed by the, pin 300 to the drop link 301, the opposite end of which is-jointed by the pin 302'to the ejector lever 303 journaled on the fulcrum pin 304i in the bracket 305 secured upon the cross bar 306 of the leg 3.

rlhe shorter rear arm 307 of theejector lever 303 is jointed by the pin 308 to the fork 309 of the spring bolt 310 surrounded by the compression spring 311 impinging beneath the spring bolt bracket 312 secured upon the frame 1 and the spring bolt is provided with acollar313 at its upper end to limit the downward stroke ot saidspring bolt. The counterpoise 31a at the inner end ot said short arm 307 is of sutlicient weight to exactly counterbalance the longer arm 303 'of the ejector lever, with all 'parts supported thereby. Said long arm ofthe ej ector lever 303 `is of such length that its end pin 315 coincides with the transverse axis of the jaw mechanism of' the press. The ejector pinis journaled by said pin 315 to the ejector link 316, jointed at its upperend by the pin 317 to the inner face of the cross head 318, riding in the crosshead way 319,A secured to the inner face of frame 1 and retained Jtherein by strips 320. Broom hooks as 321 are adapted to be interchangeably and renewably secured in the upper part of said ejector crosshead 318 by the screws 322, said broom hooks being, as indicated in Fig.

The socket link 292 clutch shaft, as indicated in Fig. 5, carries the chain 326, by which it drives the sprocket-wheel 327 mounted upon the rearV end of the conveyer axle 328 which also has intermediately secured thereon between the sides of the duplex leg 3 the plain conveyer pulley 829 adapted to actuate the endless conveyer belt 323 by which the finished -brushes are conveyed from the press in the VVdirectionof the upper arrow of said belt.

`When l employ the modified form of the central structure of my invention shown by Fig. 12, in whichV the floor plate 124 is slid beneath instead of over the dies 96, as in the arrangement shown by Fig. 8, I am enabled to feed the. broom materials directly through the elongated chute 118 preferably supplied with the separating partitions, as 141. anddispense with the compacter 122 and the following connective members show-n in Figs. 1, 7 and 8, used solely to actuate said compacter, namely: 60, 61, 129, las, isc, 152,. 154, 157, `159, icc, ici, 20a, 204, 207, eos, en, Q15, er?, 221, een, and 165, together with the connective pins and fulcra shown therewith in the views. It will be obvious, where the functionsof the compacter 122 are thus dispensed with, it is desirable that thechute 118 be considerably heightened"` in order to provide sufficient-added gravitational momentum to the broom materials to force same through the necessarily more sharply convergent type of chuteemployed in Fig. 12,thegreater taper of which is used to replace the mechanical function of compaction eXer-ted by the compacter 122, but it has been practically proven that such added momentum is adequate for the purpose stated and the members elimi nated by such modification of my invention tend to materially economize its cost of construction. p

While the general arrangement indicated in the several views represents the preferred form of my invention as actually used by me, I do `not desire to restrict myself strictly to the precise members and arrangements shown, but reserve the liberty of varying the same to any reasonable degree withoutl departing from the spirit of my invention.

The operation of my machine, largely indicated by the foregoing description of the several groups of mechanisms may be summarized as follows: When the operator has received through the chute 118 a charge of broom materials, he actuates the hand lever 114 by the handle 117, thereby lirst placing a ring 104, gravitedfrom the ring chamber 121 through the ring feed plate 246 between the dies 96 and simultaneously compacting the broom materials by operation of the compacter hook 157 upon the mechanism oit the compacter 122. Shortlybefore the conclusion of said compacter operation, the slot link 133, until then running idle, makes contact with the pin 132 at the floor plate crank 129 and causeswithdrawal of the floor plate 124, at the conclusion of which action, and the end of the hand lever stroke, the tappet bolt 270, by contact with the rock link 271, releases the release link 280 from its enga gement behind the release crank 281, thus permitting the spring 41, as indicated in Fig. 5, to actuate the clutch lever 30 so as to throw into engagement the then still clutch disk 26 with `the continuously rotating clutch disk 23 constantly driven through the train of gears 16, 14, 8 and 7 by the motor 5, thus throwing into operation through the clutch shaft 22 the crank disks 43 and 44, the crank link 48 and the crosshead 56. During the iirst increment of motion-of said crosshead 56, the wedge bracket 62 thereof moves away from, and the crosshead collar 59 moves toward the stationary trunnion block 63, through which said crosshead 66 rises idle while the wedge cam 208 actuates, through the roll crank 204, the broom corn'inserter link 215, rock lever 217, rock links 221 and 221, compacter links and compacter rods 165, the compacter 122, so as to insert its compacted charge through the wai-ting oval broom ring 104, as indicated in Fig. 8 at the end of which vertical stroke of the compacter the contactlof the spring bolts 198, 199, with the frame 1 releases the detents 200, 201, so as to open the compacter for receiving its next charge.

Upon the end ofthe broom corn inscrter Y stroke, the crosshead collar 59, by contact with the trunnion collar 63, imparts the power through the crosshead links 66 and 67 directly to the crank arm 70, and simultaneously through the synchronizing link 72, to the crank arm 78, thus synchronously giving a straightening actuation to both cranks and compressing the materials i11- closed within the broom-ring held between the dies 96, until the same shall have been given the full compression required for the formation of the brom. Atthe end of the foregoing semi-cycle, which consumes the first 180 of the revolution of the crankpin 45, the direction of motion of said crosshead 56 being reversed, the respective crank arms 70 and 78 are each actuated in a direction opposite to that first imparted to them, thus moving the cranks which had been Straightened by the foregoing compression operation, and the press starts to open, releasing i. sequently ejects the broom with which said hook is engaged, so that it ialls down upon the eti-bearing conveyor belt Near the extremity of the ejector stroke, the tappet bolt 330 depresscs said spring1 bolt 293, thus permitting the plungerbolt 291 to pass thereover, as the then compressed spring 310, acting in unison with the counterpoise 314 ele= yates the ejector beam 303 and broom hook 321 to t-heir first position, which return is instantaneously accomplished. Near the extremity ot the outer opening stroke oirI the opposite die block 93, the release crank 281 makes Contact with the release link 280 and throws the same inward, thereby releasing through the clutch shaft 39, the clutch crank 38 and the clutch lever 30, the clutch disk 26, from engagement with the clutch disk :23, and leaving all parts ot the broom press, excepting the continuously running gear train and the motor, stationary, in readiness `for the recept-ion ot another broom making charge oit materials, the position of the various parts of the machine then. being as indicated in Fig. f2.
