BURLING OR PERCHING ROLL.

SPECIFICATION forming part of Letters Patent No. 776,260, dated November 29, 1904.

Application filed March 30, 1904.

To all whom it may concern:

Be it known that I, ARTHUR L. ROBERT- SHAW, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Burling or Perching Rolls, of which the following is a specification.

My invention relates to an improvement in burling or perching rolls. It provides means for mechanically reeling the web in either direction, so that the percher is able to give his full attention to the inspection of the cloth and is not required to manipulate the same by hand.

It further consists of convenient means within the reach of the percher or operator for changing or reversing the motion of the web.

It further consists of novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents in perspective a set of perching-rolls embodying my invention. Fig. 2 is a fragmentary side elevation of a portion of the device in a different position. Fig. 3 represents in front elevation a modified form of my device. Fig. A is a vertical section through the line m, Fig. 3.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a roll mounted on a shaft 2, which is rotated in bearings 3 by means of a pulley 1. 5 designates a similar roll mounted on a shaft 6 rotatable in bearings 7 by means of a pulley 8, the axes of the rolls 1 and 5 being parallel with each other. Substantially above the rolls 1 and 5 are suitably-supported guiderolls 9 and 10. The pedestals 11, in which the bearings 7 are found, are provided with parallel upward projections 12, forming therebetween a slot 13, in which is rotatable and vertically movable a shaft 14, bearing a roller 15. Belts 16 17, passingover overhead pulleys, (not shown,) engage with the pulleys 4 and 8, respectively, but are normally slack thereon. Pivoted in a lug 18 is a lever 19,

having secured thereto a transverse rod 20, the ends 21 22 of which are turned at a right Serial No. 200,699. (No model.)

angle and so as to bear against the belts 16 17, respectively.

The operation is as follows: A web of cloth 23 is wound on the roll 1 and its end passed over the guide-rolls 9 and 10 for examination. After starting the work of perching or examining the cloth the operator winds the end of the web around the roll 15. He then pushes the lever 19 back to the position shown in Fig. 1, so that the end 22 of the rod 20 bears against the belt 17. This tightens the belt on the pulley 8, which is thereby caused to rotate the roll 5 in the direction of the arrow, Fig. 1. By reason of the friction of the cloth 23 on the roll 5 the roll will be rotated and the cloth slowly wound off the roll 15, the roll 1 running idly. By varying the position of the handle 19, so as to produce a certain amount of slip of the belt 17 on the pulley 8, the operator may reduce the speed of travel of the web 23 to a Inininuin. It is obvious that he may at any time stop the movement of the web by bringing the handle 19 to a median position where both belts are slack, so that he is enabled to dress the cloth or remove any imperfection. It is also clear that by drawing the lever 19 to the forward position (shown in Fig. 2 of the drawings) he is able to reverse the travel of the web, so as to rewind it from the roll 15 onto the roll 11.

Any one of several well-known means may be applied to the lever 19 to hold it in its adjusted position,so as to prevent any movement of the rod 20 except that given it by the operator. l have therefore deemed it unnecessary to illustrate or describe any particular mechanism for this purpose.

In the form of device shown in Figs. 3 and at of the drawings the web of cloth 23 is wound on a roll 15 and a second roll, 24:, having a shaft 25. In each of the pedestals 11 are mounted shafts 6 and 26, respectively, carrying rolls 5 and 27. Mounted on each pair of pedestals 11 are parallel transverse rods 28 29, on which slide brackets 30 31, provided with parallel upward projections 32 33, leaving spaces 34. therebetween. Vertically adjustable in these spaces 34: are shafts 14 and 25, respectively. It is evident that when the handle 19 is brought to its rearward position, as described in connection with Fig. 1, the belt which actuates the roller 5 will be tightened and the roller turned in the direction of the arrow, Fig. 4, to draw the web 23 downward and forward by means of the frictional contact of the cloth on the roll with the roll 5. It is also clear that when the handle 19 is brought forward to the position shown in Fig. 2 of the drawings the roll 27 will be rotated to rewind the cloth on the roll 24. To insure the even movement of the cloth on both rolls, I connect the rolls 5 and 27 by a web or band 35 of heavy cloth, canvas, or other friction-producing material. It will be understood that the brackets 30 31 may be shifted longitudinally of the rods 28 29, so as to accommodate web 23 of different widths.

It is evident that various changes may be made by those skilled in the art which will come within the scope of my invention, and 1 do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A perching device comprising a clothroll, a guide-roll above said cloth-roll, a rotary roll parallel with said cloth-roll, a second clothroll, bearings for said second cloth-roll adjustable with relation to said rotary roll and alternative means for actuating said last-named roll and said first-named cloth-roll.

2. A perching device comprisinga plurality of cloth-rolls, pulleys operative to rotate said cloth-rolls, means for holding the cloth in position for examination, belts normally slack on said pulleys and manually-controllable means for alternatively tightening said belts, whereby either of said rolls may be rotated.

3. A perching device comprising parallel rotary rolls, brackets longitudinally adjustable adjacent one of said rolls, a cloth-roll above said last-named roll, a shaft on which said cloth-roll is mounted, and bearings in said brackets in which said shaft is vertically movable.

4. A perching device comprising rotary rolls, rods mounted parallel with one of said rolls, brackets longitudinally movable on said rods, a cloth-roll, a shaft on which said clothroll is mounted, and hearings in said brackets in which said shaft is vertically movable.
