Application ined June zz, 1897. l

To @ZZ whom-it 11j/ty concer-n.-l

Be it known' that I, 'PHILIPP'GroLIDsCHMIDT7 a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented'certain new and useful Improvements in Lease Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in the construction of the warp-reed as it is known and used up to the present date, and as my invention has for its object to provide a novel construction as a substitute for any of the warp-reeds now used a description of the old reeds will be in place and a necessity in order to properly understand wherein m yinventive idea lies.

As the object of my invention will appear most clearly defined in a comparison of the old system with my improvement, I willirst enumerate and explain the different figures and then proceed with the description of the old system of reeds, accompanied by a parallel statement of the object of my invention.

Figure 1 is a side view of the warp-reed bracket attached to any ordinary warpingmill. Fig. 2 is a top view of parts shown in Fig. 1; Figs. 3, 4, 5, and 6, the different kinds of reeds that can be used in forming the crosses in the warp; Fig. 7, a front view of my improved combination warp-reed; Fig. 8,

a side view of Fig. 7; Fig. 9, a detailed side view of parts of Fig. 8; Fig. 10, a side view of one of the side frames of my improved reed; Figs. 11, 13, 15, and 16, broken Views of the bars, each figure showing one of the four faces of t-he two bars with the dilerent systems of teeth; Fig. 12, an end view ofthe bar pair illustratedin Fig. 11; Fig. 14, an end view of the bar pair shown in Fig. 13; Fig. 17, a front view of one of the dent-guides; Fig. 19, an end view of both dent-guides; Fig. 18, a top view of Fig. 19, and Fig.`20 shows my improved dent.

In Fig. 1, A indicates the warping-mill on which the warps are wound after having the Serial No. 641 J774. (No model.)

cross inserted which separates the threads into single, double,threeply, or double-and-single warp.

A represents a bracket which at one end has attached to it any one of the four reeds illustrated, of which B produces a singlethreaded warp; B2, double Warp; B3, threeply warp, and B4, single-and-double warp. Through one of these warp-reeds-B, forinstance-the threads are guided, each coming from its'spool on lthe creel. From there it passes through what is called the sectionreed B5, from whence it passes under a roll B6 and over a roll B7 and on to the warpingmillA. It is during the passage (indicated by letter @c in Figfl) from the warp-reed B to the section-reed B5 that the cross is secured, binding the threads into the necessary divisions which form the warp, and this operation is accomplished in the following manner:

Supposing that the reed B (shown in Figs. 1, 2, and 3) be taken as an example, it will be seen when looking at Figs. 3 and 2 that if a thread be inserted between each of the vertical dents they will appear as illustrated in the top view Fig. 2 and that if the operators arm or a stick be laid across the entire span of threadsat, for instance, the place marked Y--and a downward pressure be eX- erted on the stick the threads, which are all inserted at the line Z, Fig. 8, will divide themselves into two distinct and separate partsin fact, form a shedfor the reason that every other thread will be stopped at the parts marked O in the reed B', said part C being the piece of soldering that joins two dents together, thus forming a rest or stop for a thread, While the other half of the threads will be carried down to the bottom of the frame. The operator then inserts between the shed thus formed a thread, technically known as the cross-thread, forming the cross, and this ties together in the warp proper the threads thus divided, ready then to be wound on the warping-mill. It will then be apparent that if another division of the threads is required or any other cross is desired in the warp-for instance, the double warp, as in the shed formed by the reed Fig. 4--and the same process be followed by the operator then in the division of the threads in the case of Fig. 4 two threads will be stopped IOO at the soldered parts C', while the next two will be carried down to the bottom of the frame, and so on, and consequently when the cross-thread is inserted in the shed thus formed a double warp will be formed, and such will also be the case in the use of the reed Fig. 5, when three threads will .be

stopped by the soldered parts O2 and the next three threads be carried to the bottom of the frame, and in the use of the reed Fig. 6 one thread will be stopped by the soldered part C3, while the next two will be pressed downward. erations into one, or, in still plainer terms, in

reconstructing these four reeds B', B2, B3, and Y B4 into one single frame D, as illustrated in Fig. 7, having the necessary mechanical means to change the four diderent combinations of threads--single, double, three-ply,

and single-and-double warp--by oneeasy adi j ustable operation lies the objectofuny invenl tion. Thegreat advantage derived from this improved reed will be found to residenot only Y in the saving of the silk which has to be cut oi and wasted at the change from one of the old style reeds to another, but over and above all in the time saved bythe operator, inasmuch as each individual lthread has to be led between the dents and adjusted proper1y,'a piece of work that generally occupies from one to two hours, whereas in my improvement, as will appear presently, this whole transaction of changing `from one reed to another only occupies at most five minutes. tioned two of no smallimportance, the first being this, that as all the dents E in the old style of reeds are in one body on account of being soldered together, the said soldering 1C,

C', C2, and C3 forming the rest `for half `of the have been unwou nd looser from the spoolthan its neighbor the probabilities are that it would become entangled with it, and in time oneor both `threads would snap. This is easily overcome in my invention, as will be apparent as the-description proceeds later on by setting one of my reed-bars a trifle apart from the other, thus separating the individual threads and preventing` their becoming entangled.

From the above explanation of the dents, describing their loose and "independent `attachment to each other, it will be readilyseen that the mechanical `means embodying the principle of changing the different sheds re- In the combination of these four op- Of other benefits derived may be mensides, broadly, in a connection between the dents and the bars, enabling the latter by appropriate means to be connected and disconnected from the dents at any desired moment-that is, when a change of shed is demanded.

I shall now proceed to the description of my improved' warp-reed as illustrated in a front view in Fig. 7, Where F and F constitute the two side frames in my reed and are attached by lugs F2 and F3 to the bracket A', taking the place of reed B', as shown in Fig. 1. Securing these two frames together are ythe dent guide-rods G', which pass through the holes G2 and are secured on the outside by nuts G4. The dent-guides Gr themselves act as bracing-rods between thetwo side frames, being secured in notches G3, cutout in each frame to that effect.

H indicates my improved dents, having slits H', through which the threads pass, and loops H2, into which tit the teeth R, `secured to the four surfaces of the square bars K' and K2. This connection between'the loop in the dent andthe pin or tooth on the `bar-face is, as can be readily understood from the drawings and the description, entirely loose and must of ,a necessity be so inorder that the pins or teeth R on the bar maybe capable of elevating all the dents `simultaneously and immediately when a new pairfof contiguous oppositely-'lyin g bar-faces are presented, and equally so at the same time `the pins must `be capableiof instantaneous disconnection from the loops when another pair of bar-faces are desired. The dents are further supported on the dent-rest J, which itself is pivoted on pivots J' and J2, said pivots fitting into holes J3 in each side frame.

As seen in Fig. 8, `the dent-rest will swing around the pivots if unsupported, `and to keep it in a horizontal position, so as toma'ke it a rest for the dents, `a pin J, with a tapered surface on its underside, is secured in the frame F', said `pin J" manipulated by a knob J5. Sliding in guiding-grooves L, cut out longitudinally in each of the side frames F and F', `are tworods L', being .placed with regard toeach other individually and with regard to the side frames F .as shown in the illustration in Fig. 9. Each one of these rods L is at the top furnished with a fork L2, which forms one of the bearings or supports forthe bar, while each rod L' `is furnished with teeth at the bottom, forming a `gear-rack L3, with which gear-racks a pinion L4 meshes, giving, consequently, when pinion L4 is turned in the direction of :arrow-head L5, an upand-down motion in the direction Yof vertical arrow heads simultaneously to ,each of 4therods L'.

A rod M has these two pnions L4 littingly se- IOO having the upper part N hinged to it by a hinge N2, is furnished for the front and rear side of each of the frames F and F', and said plate N is, by means of screws, secured to the frame in holes N3, drilled and screw-cut for that purpose in said frames. The upper part N is hinged in order to permit of the bars K and K2 being taken out and turned when a change of reed is wanted, and these hinged parts are locked to the side frames F by a spring N4, attached by a screw N5 to the top of the frames, said springs each having'knob N6, which permits the hinged part N to pass it, and then by the action of spring N4 holds it in against the frame. In Fig. 7 for the sake of clearness in illustration the two rods L', lying in front, are omitted, showing thus the grooves L in full view, while on the right side frame F part is broken away to show the gear-rack L3 on the rear rod L in full. The guides G are four in number-two front and two rear. Their construction and function are best understood from Figs. 17, 18, and 19. Each one is furnished with a square groove P for every dent, and as there are two sets of dents lying opposite to each other-a front and rear set-there is a front and rear guide corresponding to each set, as seen in the top viewin Fig. 18. To keep these separated from each other,and thus maintain the proper distance, and to keep the dent in the groove, a bar Q of the same length and height dimensions as the guide and a breadth or thickness equal to the distance between the front and rear rows of dents, (indicated by the letter W in Figs. 12 and 19,) is provided, and these guides, by having the longitudinal semicircular groove G3, alluded to formerly, furnish a rest for the rods G', that secure the side frames F and F to each other. Each of the bars K and K2 is placed with one of its ends in the bearings L2, furnished at the top of rods L', and each front and rear bar is consequently supported, respectively, in two front and two rear supporting-rods. The part of the end of bar fitting in said bearings L2 is a groove K3, cut at a vright angle with the axis of the bar. Each bar is a square in cross-section, and each of the four surfaces has a channel K4 running lengthwise with the axis of the bar. On each of the four surfaces of the bar (and as they both are constructed alike one description will suffice for both) there is in a suitable mechanical manner affixed a row of pins or teeth, as they appropriately might be termed, (called R in Fig. 7,) and to each of these rows of teeth when the two bars are in their 'proper places secured in their bearings, and consequently the teeth from each upturned surface act in unison, as in the position shown in Fig. 8, corresponds a reed of the old style, as seen in either Figs. 3, 4, 5, or 6. The comparison is as follows: To the singlewarp reed B correspond in function the two rows of teeth shown on the first surfaces of each of the bars in Fig. 11. To the doublewarp reed B2correspond the two rows of teeth shown in the second pair of surfaces shown in Fig. 15. To the three-ply-warp reed B3correspond the two rows of teeth shown on the third pair of surfaces in Fig. 13, and, finally, to the double and single warp reed B4 correspond the two rows of teeth shown on the fourth pair of surfaces shown in Fig. 16.

I have said in the foregoing that the bars are constructed alike, but with this one difference, that, as will be observed in all the Figs. 11, 13, 15, and 16, the teeth R, that catch in the loops H2 of the dents H, and consequently the dents themselves, are placed crosswise toward each other, so that the space between two dents in row O in Fig. 11 has a dent in row O lying opposite to it, and so throughout both of the rows, and as this applies to the dents that are laterally fixed by the guides the front and rear rows of dents are thus placed crosswise toward each other-viz., a dent on one side and a space on the other, and so on-and in order to facilitate a better understanding of the mechanical principle of my invention it may be said that this crosswise position of the dents makes this invention a possibility.

It will now be seen that as the main principle lies in the application of the cross-thread in the formation of a shed which will permit one half of the alternate threads to be separated trom the other half, so that a crossthread can be inserted through the shed thus formed, tying the two separate positions of threads together, if such a shed could be formed for the operator,y leaving his hands free, a great advantage would be gained. This I accomplish in the instance just described, in the case of a single-thread warp, by having the pins R attached to each bar in rows O and O', each pin accurately fitting into its loop H2 of the nearby-lying dent H, so that when the bar is pushed into its two supports L2 all the pins enter their respective opposite-lying loops at the same time, ready for the manipulation of the hand-wheel. It' then hand-wheel M3 be revolved, hausing the rack-pinion L4 and the respective racks L3, gearing thereinto, to move, respectively, up and down, as indicated by the arrow-heads, the two barsv will be carried apart, and the pins attached to the bars each fitting into a -dent-loop the front row of dents will be elevated while the rear row is being depressed, or vice versa, and as the dents have the threads passing through the slits H it is easily seen by looking at Fig. 11 that every other thread in the dents having pins in row O in their loops will be elevated, while the threads in the dents having the pins in row O in their loops will be correspondingly depressed, and thus a shed will'be formed which when the cross-thread is inserted will form a singlethread warp. When a double warp is required, the warp-reed B had to be replaced by the warp-reed B2, the threads had to be IOO cut away,'and a new thread from each spool on tl21e creel had to be led between the dents in B In my improved device the threads remain inlthe dents, and the operator simply unlocks the hinged part N of the protection-plate N, (see Fig. 8,) takes out each of the bars, and inserts them again with the surfaces shown in Fig. l5 uppermost, the teeth turning toward each other. As the object in a doublethread warp, as apparent from Fig. 4, is to divide the two halves of threads up so that two threads are up while two are pressed down, two up and two down alternating all along in the warp, the pins must elevate or depress their respective dents to that eect, so that every other two threads will be depressed and every other two threads will be elevated. This takes place by R', for instance, elevating two pins, dents, and threads; R2 depressing two pins, dents, and threads; R3 elevating two pins, dents, and threads; R4 depressing two pins, dents, and threads, and so on. If a three-ply warp was desired, the threads had to be cut and again inserted through the frame B3, taking the place of B2 in the bracket, whereas the operator, as in the case of the double-thread warp, only need open the hinged plate N', take out both the bars, and turn them until the surface shown in Fig. 13 comes uppermost, when it will be seen that the pins are so arranged as to fulfil the requirements demanded by the frame BS-viz., to elevate every other three threads while every other three are depressed-as, for instance, pins S will catch up three successive threads and elevate them, while pins S will depress three, S2 elevate three, S3 depress three, and so on. Finally, in the case of a single-and-double warp being required the same operation of changing the bars will have to be gone through, and in comparing the reed B4, which would have to be inserted in the bracket A in order to provide a doubleand-single warp, with the pins on the surfaces of the two bars illustrated in Fig. 16 it will 'be seen that while pins T elevate two threads pin T depresses one, T2 elevates two, T3 depresses one, and so on.

An explanation of the mode of operation would plainly be a repetition of the foregoing, inasmuch as the cooperative elements have had to be so clearly defined and theY functions of these are so closely connected with the very simple operation of my device that in brief it is only necessary to state that in having a framework, as illustrated in Fig. 7, if two bars K and K2, furnished with pins on their four surfaces, each surface representing a diiferent kind of warp, are by means of a hand-Wheel M3 attached to a rod M, having rack-pinions L4 keyed to it, and each pinion gearing into a front and rear rack carrying said bars, moved to and from each other, a shed will be formed which, ac'

cording to whatever bar-surfaces may be uppermost, and thus actin g by the pins attached to them on the two rows of dents,will furnish a shed to the operator, out of which shed crosses can be formed for the function of either a single, double, three-ply, or singleand-double warp or any other warp that may be desired, which was the object of my invention.

From the foregoing it will now be easily seen how the operator can avoid two parallelrunning threads from becoming entangled, as frequently is the case in the old style of warp-reeds, where of a necessity the threads always must run parallel, by simply turning the hand-wheel M3` slightly, which then, no matter what warp is being formed, will separate the threads into two half parts-an upper and a lower-consequently lessening the chances of entanglement between the individual threads.

That I do not limit myself to a bar with either more or less than four sides will be apparent, inasmuch as if any one should elect to use only one or two or three surfaces with any assortment of either of the four mentioned warps or any other formation of warps that might be invented from time to time it would in. no wise be an innovation on my inventive idea, nor would the change in the cross-section of the bar from a polygonal to a circle, in fact making the bar a cylinder f1tted with means for operating the dents and having all the functions appertaining to a cylinder, alter the character of the conceptive idea in my invention, for

What I claim as new, useful, and not hitherto known, and desire to secure protection for by Letters Patent of the United States, is-
