SPECIFICATION forming part of Letters Patent NO. 779,799, dated January 10, 1905.

Application filed July 18, 1903. Serial No 166,121-

To all whom it may concern:

Be it known that I, LOREN W. PENNEY, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts. have invented a new and useful Improvement in Drawing-Frames and Similar Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

Heretofore the rolls of drawing-frames and similar machines have been yieldingly held together by means of weights which have been so coupled or attached to the upper rolls as to require that the weights be lifted and disengaged from their couplings and that the couplings when thus released from the weights be lifted from the rolls in order to permit of the removal of the upper roll or of both the upper and lower rolls from the stands.

As it is neceesary to quite frequently remove one or both rolls from the stands and as the weights and their couplings are so arranged within the machine as not to be readily reached, handled, and moved and as the weights are also heavy, it followed that the release of the rolls from their weights or their adjustment to varying lengths of staple was a somewhat arduous and slow undertaking, and it is to overcome the objection caused by this unhandy and undesirable construction and to save time in the adjustment and operation of the machine that the present invention has been made.

The invention consists in so connecting the weights with the rolls and their stands that the rolls, or any of them, may be disengaged from their weights and from the stands by a movement of each weight coupling or connection which shall not require that the weights be lifted with regard to the rolls or that they be disconnected from their couplings and which shall also so connect the roll-blocks with the weights that such of the blocks as may require to be moved horizontally upon their supports for the purpose of varying the distance between the rolls to adapt them to,

work upon varying lengths of staple may be so adjusted without disconnecting their respective weights from them that is, the various blocks and their respective weights are adjustable together .without changing in any way the relation of the weights to the blocks or of the weight-couplings to either.

In the form of the invention as hereby disclosed the blocks form a part of each stand and contain bearings for the lower rolls and holders for the boxes of the upper rolls. They are made longer than has heretofore been customary and so as to extend beyond their supports, and excepting the first one in order they are horizontally adjustable with respect to each other and lengthwise the support. Each of the blocks, including the stationary one, is combined with one or more weights by means of a weight-coupling attached to the block in such a manner as to be capable of a turning movement in it, a slight vertical movement in it, and a horizontal movement with it and with the weight it supports. Each coupling may also be so combined with the box as to prevent undue rocking or chattering of the upper roll.

The vertical movement of the coupling is for the purpose of permitting the upper roll to be lifted from the lower roll by the staple or roving which passes between the rolls. The turning movement of the coupling is for the purpose of permitting its offset upper end above the block and roll-box and which acts as a foot and also as a handle and as a turning device to either actively rest upon the box of. an upper roll or to passively rest upon the roll-block at one side of the upper roll-box when it is desired to remove the upper roll and its boxes from their holding-blocks and also the lower roll, if necessary. This turning movement of the coupling is a quarterrevolution in extent and enables the rest to either extend across the upper roll-box or to be moved upon the block to be lengthwise it and to be then'in that position so held as not to overlap upon the outer side of the block or upon its box-holding recess. This is essential, because the space between the box-holding recesses of the boxes, which are close to each other when short staple is being worked upon, is so narrow as not to afford any other disposition of the coupling handle and foot. The surface of the box upon which the coupling-rest bears and the surface of the block upon which the co u pling-rest also bears should be of substantially the same level, so that the rest may be easily and readily turned from one to the other.

The combining of the weight or weights of eaclrblock with the block by means of a coupling which connects the weight or weights with the block permits the simultaneous movement in the adjustment of the blocks and rolls for variations in length of staple of the block, the weight or weights, and the coupling or couplings without changing their operative relation to each other.

The provision for preventing the rocking of the upper roll consists in so arranging the coupling-foot that a portion thereof when it projects over the roll-box shall upon a downward movement of the roll-box caused by a rocking movement of the roll-shaft come into contact with a stop on the block, thus relieving the upper roll and its box from the stress or effect of the weight while the end of the roll is depressed lower than is desirable because of said rocking motion, and this release of the roll from the weight tends to reduce the rocking movement and also to prevent it from being unduly worn by said rocking movement.

By causing the weight-couplihgs to pass through the blocks of the roll-stands the couplings are also protected by the stands from accumulating deposits of grease and other matter, so that they do not require cleansing as often as they do with the constructions now in use, the roll-stands acting in the nature of a housing for the couplings.

I will now describe the invention in conjunction with the drawings forming a part of this specification, where-- Figure 1 is a view in plan of enough of a drawing-frame to show the construction and operation of my invention. Fig. 2 is a view in cross vertical section thereof. Fig. 3 is a view in elevation thereof. Fig. 4c is a view in plan of a modified form of the construction of the roll-blocks of the rolls, which are placed closely together and so that they may be made sufliciently Wide in parts to contain the holes required for the connections between the weights and the rolls. Fig. 5 is a detail view of a roll-block and a portion of a coupling to illustrate the use of the block as a stop in preventing the coupling from following the downward movement of the roll-box beyond a given point and when the roll is rocking.

The drawing-frame shown in the drawings may have the common complement of lower rolls A and upper rolls B, and they may be of the usual construction. They are mounted in the roll-stand (J, as hereinafter stated. The

lower rolls may be continuous throughout the frame, and they are positively driven. The upper rolls are preferably in short sections of a length to span two stands only, and they rest upon the lower rolls or the roving which passes between them and are driven by the lower rolls through the roving.

A usual construction of the lower and upper rolls showing their working and bearing sections is represented in Fig. 3.

The stand comprises in part a number of blocks G. They are mounted upon a support 0 and have, with the exception of the first in order, horizontal adjustment thereon independently of each other in order that the rolls may be horizontally adjusted with respect to each other according as the length of staple which they work upon varies. The usual manner of mounting these blocks upon their supports, of adjusting them horizontally thereon, and of locking them thereto may be used. Each block is of a length to extend beyond each side of the support, excepting, of course, the end ones of the stand, to provide a part through which the Weight-couplings may extend, as hereinafter stated, (see Fig. 3,) and so that the couplings may extend through the blocks, but not through the supports for the blocks. Each block has opening fromits upper surface a deep box-holding recess 0, the rounded bottom of which forms a hearing c for the lower rolls, which are reduced in size at a, where they rest in the bearing, and between the shoulders a a upon each side of the block. (See Fig. 3.) The upper rolls are mounted in the boxes 6, (see Fig. 2,) and the boxes are squared to fit their recesses c and to be held from lateral movement by the sides 0 thereof; but they are free to have restricted vertical movement therein. The box-holding recesses 0 are open at the top to permit the ready removal from the stand of the upper rolls and their boxes and also, when desired, of the lower rolls. Each box has a longitudinal bearing 6 extending through it, into which an end section b of the upper roll extends. These ends are reduced in size as compared with the size of the working sections, and the boxes are sufficiently short in height to not come into contact with the sections (6 of the lower rolls. With this organization in mind I will now describe the means employed for yieldingly holding the working portions of the upper rolls in contact with the working portions of the lower rolls and in a manner to have such pressure as may be required immediately applied to them or immediately removed from them, and so that the rolls may be quickly disengaged from the stands and be replaced.

The most convenient way of applying pressure to the rolls of which 1 have knowledge is the manner now in useviz., weights. Two weights are employed for each upper roll, one near each end thereof, and this brings two weights adjacent to each stand,except the bed d and in the central and lower part of the frame, which is their usual location. Each weight is connected with a box 6 of an upper roll by means of a coupling-rod The rod is attached to the weight in a manner to permit itto be turned therein without turning the weight, and each rod extends upward through a long hole in the beam provided for them and through the vertical hole d3 in the overhanging end of each roll-block, which hole is arranged closely to one side of the boxrecess, (see Fig. 2,) and so that the rod shall pass up through the block at one side of the box and also outside of the block-supports. The rod projects abovethe block and is of suiiicient length to be there formed into an eye, button, or handle cl", the lower part (Z of which forms a rest which is adapted to bear either upon the upper surface of the box?) or upon the wall of the block, according as the rod may be turned. l/Vhen the rod is turned to release the box, its overhanging eye or handle will still support the weight, which will then rest directly upon the top of the block instead of upon the box, and the upper roll and its box and the lower roll are then free to be detached from the stand by an upward movement. I

The box may have a slight depression or seat (Z extending across it to receive and hold the seat (5 of the rod and in a way to prevent it from being jarred out of engaging position with it, the slight shoulder upon each side of the recess serving as a stop. The same result is secured by forming the cover E (see Figs. 2 and 3) with the lugs or plates 6, which close upon each side of the handles or eyes (1* when the rods engage a box and hold them from turning.

A convenient way of attaching the weight to each rod is represented in Fig. 2, where the weight is represented as having a hole (Z extending across it near its upper end, the upper surface cl of which is slightly inclined and from which extends upward the recess (Z open at one side. The hole (Z is of a size to receive the adjustable collar (Z10 on the lower end of the rod. The collar is detachably secured to the rod by a set-screw and has the rounded surface (i upon which the inclined surface (Z of the weight bears, and the rod extends through the recess (Z This permits the rods to be readily placed in their boxholes or to be removed from them, the weight and the rod to be easily combined without detaching the collar, and it also hangs the weight upon the rod, so that jar will not serve to disengage or work the weight from the collar, such jar as there may be serving to maintain the weight centrally seated on the collar. The construction is also such as to permit the turning of the rod and collar within the weight without turning the weight.

It will be understood that each upper roll is held to the lower roll by two independent weights, that each of these weights engage an end of the upper roll through its box by a rod, that each rod serves to connect a weight with or hang it upon the roll, that it also serves to communicate the slight vertical movement of the roll to the weight, and that it further serves as a means for disengaging the Weight from the roll without disengaging it from the block. Consequently it has capacity for vertical movement in the block and capacity for turning upon it, so that the por-- tion which engages the upper roll or its box may be moved from itto a position at one side of it. It will further be noticed that the rod serves also to hold the weight to the block when it is not engaged with the upper roll or its box. While these various functions are illustrated as contained in a single integral connection between the'weight and the the roll-box, as this seems to be the best form in which the invention can be embodied; I do not, of course, confine myself to a structure employing a single integral rod, but may use any modification of the structure which shall insure a connection between the weight, block, and the rollbox which shall be capable of engaging the weight while coupled to the block with the roll-box or disengaging it therefrom and without disengaging the weight therefrom.

The coupling of the weights to the upper roll through the standblocks secures the weights to the stand-blocks and permits the stand-blocks to be used as a means for adjusting the horizontal position of the weights and of the weight couplings when horizontal adjustment of the rolls with relation to each other is necessary, and either in the original putting together of the machine or later for exigencies of operation.

I prefer that the rest (Z of the coupling-rod be of sufficient length in its active position on the roll-box to extend from the box over the portion of the block between the straight part of the rod and the box, (see Fig. 5,) and this part of the rest, in connection with the block, serves to hold the weight from following downward the roll-box in case of the tipping of the roll in rocking to a position below the upper surface of the portion of the block referred'to, and thus prevents an .increase or continuation of the rocking movement of the upper roll and injury to it while rocking as well.

It is hardly necessary to describe specifically the operation of the invention, as the way in which the rods are operated by turning to make engagement between the weights and the roll-boxes and disengagement therefrom so that the rolls and roll-boxes may be removed has been sufficiently given. I would add, however, that the arrangementwhich I have shown is very desirable, not only for the reasons already given, but because it is a cheap and simple construction and one that is also very compact and disposes of the means for engaging and disengaging the weights so that they are not in the way at any time, do not conflict with each other, and are equally unobjectionable in their position whether a'cting to hold the weights engaged to the rollboxes or whether acting to simply suspend the weights from the stand when it is desirable to remove the rolls from the stand.

Some of the rolls require to be placed closely together notably the first and second sets of the seriesand where this is the case the bearing-blocks must be made narrowso narrow, in fact, that unless provision is otherwise made the holes (6, required for the connecting-rods, will pass through the edges of two blocks. This, of course, is not a desirable construction, and I therefore for such blocks so make them that the parts through which the holes (Z pass shall be of sufficient thickness to permit the entire holes to be formed in them, and this is accomplished by forming these blocks as represented in Fig. 4, where recesses are formed near each end of one block, which permit corresponding enlargements to be made near the end of the next adjacent block and in which enlargements the holes d" are formed.

I prefer that the blocks be made relatively long and to have a considerable overhang from their supports, also that the boxes for the upper rolls extend laterally from the ends of the blocks an appreciable distance and that the coupling rods be arranged to extend through the blocks as near their ends as possible and when in engagement with the boxes of the upper rolls to bear upon them near the center of their length. This construction provides longer bearings for the rolls than has been customary and applies the weights to the upper rolls at the best place to reduce their rocking action.
