SPECIFICATION forming part of Letters Patent No. 638,975, dated December 12, 1899.

Application inea August 2, 189s.

To all whom, it may concern:

Be it known that we, CHARLES MILLs, ot' Newton Upper Falls, and LOREN WV. PENNEY, of Newton Highlands, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Drawing-Frames, of which the following is a descriptionsufliciently full, clear, and exact to enable those skilled in the art to which it appert-ains or with whichit is most nearly connected to make and use the same.

This invent-ion has relation to that class of machinery employed in the preparation of textile bers for the operation of spinning, commonly known as drawingrames or drawing-machines, employed chiedy for the purpose of improving the parallelizing of the tlbersand the equalization of the weight and thickness of the slivers treated thereby.

It is the object of the invention to so improve an organized drawing-frame as that the principal purposesthereof may be carried out more efficiently, economically, and conveniently than heretofore.

In the disclosure of the invention as will hereinafter appear a description will be given of the structural character of the improvements created and the mode of their operation will also be set forth, and in connection therewith, where it isnecessary, the advantages gained and mischiefs or objections overcome will also be stated.

Reference is to be had to the annexed drawings, and to the letters marked thereon, forming a part of this speciiication, the same letters designating the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure lis a plan view',partially in section, of so much of a drawingmachine as it is necessary for the purposes of this speciication to show, the said drawingmachine being equipped with our improvements. Fig. 2 is a plan view of a portion of the rear roller of the pair of delivery-rollers detached, showing our improvements so far as they are -connected therewith. Fig. 3 is a vertical cross-sectional view taken through the upper part of a drawing-machine provided with our improvements. Fig. et is a partially-sectional view of a trumpet and its adjuncts and some of its copcrating parts,

Serial No. 687,532. (No model.)

as will more fully appear hereinafter. Fig.

p 5 is a diagrammatic View, in side elevation, of

a stand for supporting the gearing for operating the rollersV of the several heads in a drawing-machine. Fig. 6 is a plan view of the stand and most of the gearing, as well as the pulleys for operating the gearing. Fig. 7 is a plan View, on enlarged scale, of one of the coiler mechanisms, together with atrurnpet and appurtenances. Fig. 8 is a sectional detail view of a coiler-tube gear, its drivinggear, and some of the associated parts.

In the drawings, @designates the fixed supporting means of the machine, which may be called the frame b designates the drawing-rolls, arranged in sections or deliveries and receiving the material to be operated upon from the feedrollers c, back of which is theguide-plate cl.

The parts so far described form no part of our present invention, and therefore may be of the form shown or any other suitell'to the purpose for which they are used.

Ve designates the front calender-roller, one being required for each section or delivery, the journals of which rollers are loose in their bearings, as usual, so as to afford play to the rollers in directions to and from the rear driving calender-roller f, which is made in one piece extending the length of the frame. We make the rear calendering-roller f smaller in diameter than the front rollers and arrange the pair of rollers so as that the lowest lines of their peripheries shall be upon substantially the same horizontal plane in order that when viewed from above the rear roller will appear to be and to all intents and purposes will be lower than the front roller. This construction, for one thing, enables us to cant the trumpet h in'such manner that the sliver passing from the drawing-rollers to the cal-V ender-rollers may extend upon a more, nearly direct line than though the trumpet were held in level position, the latter arrangement resulting in advantages obvious to those skilled in the art, chief among which is the vertical delivery of the slivers into the tube of the coiler-gear.

Where two calender-rollers of the same size are arranged with their axes in the same horizontal plane, the sliver coming from the loo , downward.

drawing-rollers is required to make too sharp a bend into the trumpet, which with this arrangement of calender rollers necessarily stands vertically over the bight between the latter. On the other hand, if the calenderrollers are arranged obliquely to allow a disposition of the trumpet which will avoid the abrupt bend of the sliver, the latter will be shot forward instead of delivered directly To overcome the above mentioned difficult-ies, it has been customary to employ three rollers, the two calender-rollers set obliquely and the third being a guidingroller to direct the sliver straight downward into the coiler-tube. By our arrangement above described the extra roller is dispensed with, while all the advantages of the threeroller arrangement are retained. As above stated, the reduction in diameter of the rear calender-roller, while its lowest peripheral line is kept in a horizontal plane embracing the lowest peripheral line of the larger front roller, provides for sufficient canting of the trumpet to avoid too sharp a bend of the sliver. Again, although the axes of the ltwo rollers and the line of contact between them are in an oblique plane, yet the sliver will be delivered directly downward, owing to the fact that the large front roller is longer in contact therewith than is the small rear roller, it being borne in mind, in this connection, that the sliver expands immediately after passing the line of contact between the rollers.

We construct the driving calender-rollerf preferably of one solid piece of steel, turning down the same at intervals to form bearingnecks and cut gear-teeth z on the end of each section,-as shown, which gear-teeth t engage the teeth of the gears j, secured on the ends of the front rollers. The gear-teeth i are shortened to their pitch-line relatively to the teeth of the gears j with which they mesh. Under this improvement the front roller is disengaged from the driving means of the rear roller and delivery is stopped before a com paratively great amount of fiber becomes wound thereon and before delivery would be stopped under the construction in common use. This is a matter of much importance, since if the machine is not stopped quickly after the fiber commences to wind on the rollers serious mischief results. Again, it is more advanta geous and economical to eut the teeth upon the roller f, as we do, than to make the gear in halves and pin said halves on the roller, as was necessary heretofore with the inner gears, since they could not be slipped 'on from the end of the roller, and in addition to this the gears t, as we form them, are more durable than those heretofore formed, since it is obvious that if the teeth were long or of full length they would be more likely to be broken by reason of their subjection to greater strain. Moreover, by making the rear rollersmaller, as we do, and cutting the teeth t' thereon, as described, more space is left at the end of the roller for the employment of a greater ran gc ofchange-gearing forpreservingthe right tension upon the sliver.

k designates the main gear-stand, which is provided with a anged base Z, whereby provision is made for bolting or otherwise securing it to the top of the roller-beam in, so that,

when once secured in place it becomes to all intents and purposes one with the beam. The main gear-stand above its base may be made of a Hat piece of metal, milled on both of its sides and on its foot, so that it is easy and economical to make and finish, besides being otherwise advantageous, as will presently appear.

The main or leading feature of our improved main gear-stand is that it is so constructed as to adapt it to carry all of the end bearings and gearing necessary for driving all of the rolls and the frontcoiler shaft, whereas under former constructions of this kind it required two or three separate stands to accomplish the same purpose, which former stands had to be removed or separately adjusted when any roll or gear was taken off or adjusted.

The sta-nd is provided with a curved slot n in form concentric with the axis of the shaft 0, having affixed upon it the driving-gearp, one end of the slot a being enlarged, as at q. By this means'when it is necessary to change the speed of the calender or finishing rollers the nut for securing the journal-stud of the change-gears r in place may be loosened, the said stud moved up to the enlarged point q of the slot, the stud and gear removed, another gear or gears substituted, and the parts returned to and secured in place without disturbing the stand, and the work can readily be doneby one person. The form ot' t-he slot n provides for keeping the gear s2 in proper mesh with the driving-gear p and also for adjusting the gear r (which is fastened on the hub of the gear s2) into requisite mesh with the coiler-shaft gears on the end of the coiler-shaft d@ which gear s isa change-gear for varying speed to suit different sizes of coiler-cams.

The calender-rollers, itwill be understood, are driven from the change-gear r (which is practically compounded with the gear s2) through the medium of the coiler-shaft gear s and the idler s meshing with thegear on the back calender-roller. The gears s s for the sake of clearness are omitted from Fig. 6.

The draft-gear u, which is also a changegear, has its journal-stud supported in a bracket e, which is adjustable on the maingear stand by means of a bolt w, which may move in a slot formed in the bracket, which slot is curved in form concentric with the driving-shaft, as shown. The bracket u is on the driving-shaft, so that it can be swung concentrically thereabout, keeping the crowngear y (with which the draft-gear n is compounded) in proper mesh with the drivingwheel and also allowing the draft-gear u to be brought into proper mesh with the gear which it drives.

IIO

IZG

The removable and change gearing are arranged, as is necessary to a practical and economical construction, on the same side of the stand as that from which the rollers eX- tend. This improvement is important, since, as before shown, itv is economical and efficient, permits the work to be done by one person without removing the stand, and allows any gear to be taken out without removing the others.

.e a" designate fast and loose pulleys, from which the machine is operated and by which it is governed.

a designates the front half of the cover for the coiler-tnbe gear b,the support b" for which cover and gear extends out over the coilercan c and is rabbeted at c to accommodate the lower edge of the front half ot the cover. The front half of the said cover is made removable, While the back half Uf'is stationary. This construction enables us to readily remove the front half a of the cover by simply lifting it off and placing it to one side around the adjacent cover, as is shown in Fig. l, (a portion of the front calendering-roller being represented as broken away to better show the construction,) in order to get in to correct anything in connection with the coilertube gear or to remove the latter or any of its connections. The back part of the cover connects with adjacent covers, all of the joints being close andthe upper surfaces smooth, so that neither dust nor lint can get below the covers and so that the surfaces can easily be cleaned by dusting or brushing. Heretofore in case the sliver passing through the coiler-tube gear should bung up or in case of other similar mishap it was necessary to remove the entire cover and generally the gear also to set things right.

d designates the coller driving-shaft, arranged below the covers a and provided at each head with a small bevel-gear e', which meshes with a like bevel-gear f', setinto and connected with the hub gf, Fig. 8, of a gear 7;', which meshes with and drives the coilertube gear h'. The hubs of the gears f' and 7L turn on a stud t', set into the frame-plate, and the latter is countersunk to provide a bearing for the rimj of the hub g', so that the said countersink may be freely supplied with a lubricant and the overflow therefrom may iiow over to the recess formed in the plate for the rim-bearing 7c of the coiler-tube gear.

By the construction just described the parts are brought close together verticallyin order that they may be made compact, be easily lubricated, and otherwise made eiiicient vand ready of access.

The pivoted arm l of the trumpet is provided on its under side with an adjustingscrew m', Fig. 4, which supports the trumpet in position by resting upon a pivoted lever n', the latter in turn resting upon the coiler-gear or its cover, so that as the coiler-can becomes filled and raises the coiler-gear the trumpet willbe raised and the machine will be stopped.

The usual stopping mechanism is shown in Fig. 3, on which the arm of the trumpet acts through the medium of the usual con'trivances to stop the machine.

In Fig. l we have-shown the front half of the cover to one coiler-gear as removed and placed around and over the front part of the coiler-gear next to the right. This gives opportunity for free access to the coiler-gear and its adjuncts in an easy and convenient way.

Vte may repeat that we regard the single main gear-stand as a very important part of our invention, since in addition to what has already been said of it it leaves room for a greater range or extent of change-,gearing and allows of the same being easily and quickly adjusted and secured in place.

Having thus explained the nature of the invention and described a wayof constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is- 1. In a drawing-machine, t-he combination with an obliquely-set trumpet; of front and rear calender-rollers, the rear one being appreciably smaller than the front one and the lowest peripheral lines of the two rollers being in substantially the same horizontal plane.
