TRAClNG-CLOTH IVIANGLE Specification of Letters Patent.

Patented June 26, 1906.

, T @ZZ whom, t may concern:

Be it known that I, WILLIAM B. WAECHTER, a resident of Garfield, Bergen county, in the State of New Jersey, have invented certain new and useful Improvements in Tracing- Cloth Mangles, of which the following is a specification.

This invention relates to a machine technically known as a mangler, and is in the present instance used for a special purpose in the manufacture of tracing-cloth or the like 1n which sizing or starch is employed, it being necessary in order to produce perfect tracingcloth, that the sizing or starch be thoroughly pressed or forced into the interstices of the fabric, so that the same will become properly impregnated therein and not be liable to erasure, which occurs in ordinarily prepared tracing-cloth. By means of my improved machine the sizing is so thoroughly forced into the fabric that cracking is less liable, as the sizing and the fabric become practically one, which is not the case when the sizing is confined to the surface of the fabric, as in bending the surface of the fabric has a tendency to work away from the sizing.

To attain the objects before mentioned, I employ the special means which will hereinafter be described and claimed in conjunction with the accompanying drawings, forming part of this specification, wherein- Figure 1 illustrates my improved machine as viewed from the front, the starch or sizing reservoir being shown in section. Fig. 2 is a sectional end elevation of my improved machine, the section being taken on a line a, c in Fig. 1; and Fig. Sis an enlarged cross-sectional view of the mangling-roll, showing the engraved or roughened periphery.

Like numerals and letters of reference indicate corresponding parts in the several views.

Referring to the drawings, the numerals 1 and 2 indicate the frame-standards, which are suitably anchored to the floor or the like. As will be seen by Fig. 2, the standard 2 is provided with a guideway 8, 'the standard 1 being likewise provided with a guideway.

Within said guideways boxes 4 4 are slidably fitted, Fig. 1, and within the boxes 4 4 a wooden pressure-roll 5 is rotatably mounted by means of the trunnions 6 6 thereupon. Below the roll 5 I place a coacting pressure or material roll 7, which is rotatably mounted in the boxes 8 8 by means of the trunnions 9 9 thereon, the said boxes 8 8 being slidably mounted in the ways 3 in the standards 1 and 2. In order that the roll 7 can be leveled and v maintained so I provide threaded adjustingjacks 10, one under each box 8. (See Fig. 2.) The jacks 10 engage at their lower extremities a nut 11, while the upper end 12 of the said jack is provided with a Spanner-nut 13. The end 12 can enter an opening 13 inthe boxes 8 as a security against displacement, the nut 10 resting upon the shelf 14 at the bottom of the ways 3. By means' of these jacks the rolls 5 and 7 can be leveled simultaneously and their peripheries always maintained in contact. When the roll 7 is leveled it becomes a fixture, and the contacting pressure of these two rolls is supplied by the upper roll 5, the said pressure being produced by weights 15 15, which are adjustably mountedupon the ends of levers 16 16, which, as will be seen in Fig. 2, are fulcrumed to the standards 1 and 2, as at 17; but the weights 15 may be otherwise applied, if desired. The

levers 16 have attached thereto connectingrods 18 18, which are composed of two members 19 19', connected by turnbuckles 20 20 for the purpose of adjustment. The upper ends '19 of the rods 18 18 are connected to secondary levers 2l 21, which are fulcrumed to the standards 1 and 2, as at 23, the said standards being slotted, as at 24 24 to receive the lends of the said levers, and, as at 25 25, for the said levers to pass through, the slots 25 25 being long enough to allow said levers 21 a free up-and-down movement. Through an openin 26 in the levers 21 a threaded spindle 27 free y passes, the lower end of which engages the boxes 4 4, as shown and is free to rotate therein. The spindles 27 carry shoulders 28, upon which the levers 21 rest, the threaded portion of the spindle 27 passing through the cap 28 on the top of the standards 1 and `2 and has thereupon a hand-wheel 29 which is normally out of contact with the said caps, as shown. From the foregoing descripti on it is obvious that the full weight of the weights 15 15, multiplied by the leverage, acts directly upon the upper roll 5, Vthe amount of pressure being governed by the position of the weights 15 15.

If it should be desired for any reason, such as placing cloth between the rolls or for any IOO ' by the said gear 53.

other pur iose, the roll 5 can be raised from roll 7 an maintained out of contact therewith by means of the hand-'wheels 29, as said wheels may be rotated to Contact the ca s 28', and by rotating still further the spindlis 27 will be raised, thereby raising the roll 5. The levers 21, rods 18, levers 16, and weights will of course be raised also. For the purpose of mangling the cloth and forcing the sizing into the weave I use an engraved or roughened mangling-roll 30, which by means of the trunnions 31 31 is rotatably mounted in adjustable boxes 32 32, which are in turn slidably mounted upon ways 33 33 and adjusted toward or away from the roll 7 by means of threaded spindles 34 34, which are screwed into lugs 35 upon the standards 1 and 2, and carrying operating-wheels 36 36. The periphery of the said roll 30 is roughened, as at 37, Fig. 3, and the projections may be of any configuration that does not have a knife-point or a point that would tend to perforate the cloth. Under the roll 7 I place a reservoir 38 for containing the heated sizing material 39, Fig. 1, said reservoir being suitably secured to the standards, and under therolls 7 and partially or entirely submerged in the sizing 39 I place a small roll 40, which is rotatably supported by the reservoir 3S. Said roll 40 is a mule or idler pulley to keep the cloth submerged in the sizing as it passes along to the rolls 5 and 7. The cloth A is held by brackets 41 and is passed over an idler 42, under the roll 40, up between the mangling-roll 30 and roll 7, then between the rolls 7 and 5 at their pressure-points, and onto a receiving-winch 43. A more detailed description 'will hereinafter appear. As I desire to take advantage of a high belt speed transformed into a slower motion, I employ a system of gearing and shafting comprising a driving-shaft 44, which carries a friction-pulley 45 and a pinion 46, the said pinion meshing with a gear 47 upon a counter-shaft 48. The counter-shaft 48 carries a pinion 49, 'which meshes with a gear 50 upon the eX- tended trunni on 9 of the roll 7, which is rotated by said gear 50. A larger pinion 51 is also mounted upon the shaft 43 and meshes with an idler 52, adjustably mounted on the standard 2, the said idler in turn meshing with a gear 53 upon the extended trunnion 31 of the mangling-roll 30, which is rotated Y The proportion existing between the diameters of the pinion 49 and its gear 50 and the larger pinion 51 and its gear 53 is such that the peripheral speed of the roll 7 is somewhat slower than that of the mangling-roll 30. The roll 30 therefore tends to lead in peripheral speed the roll 7, which has a grinding effect on the cloth, which acts to force the sizing thereinto. The train of gears is suitably mounted upon standards 54 54 and an outlet 55 for the sizing is supplied.

The o eration of the machine is as follows:

Aldry ro l of cloth A is placed in the brackets 7the weave more thoroughly by the pressure of the weights 15 15. The cloth is then rolled on the winch 43. When the roll A has 'become exhausted, the cloth is then again passed through the machine and over the roll 5 and collected. (See dotted and dash lines B, Fig. 2.) To get a smooth finish, the roll 7 may be replaced by a compressed cotton roll. As hereinbefore stated, one of the principal objects of this machine is to force or grind the sizing into the weave of the fabric, which is accomplished by the roughened periphery of the mangling-roll 30. The proj ections upon the said periphery will tend to separate the weave of the fabric, at the same time forcing a large part of the sizing therethrough, it being understood that the sizing is placed in the reservoir in a heated condition. The difference in peripheral speed of the material-roll 7 and mangling-roll 30 causes a slip at the point of contact of said roll, which has a grinding effect upon the cloth and sizing. The projections upon the surface of the m angling-roll will not, of course, perforate the fabric, the difference of speed being only suflicient to cause a moderate slip and not enough to tear the material. The pressure of the roll 30 upon the material-roll 7 can be varied, as has been stated. The proportions of the gearing will be such as to give a slight difference in the speed of rolls 7 and 30, and any desired difference in speed may be obtained by changing the gears 51 and 52.
