REGULATOR FOR PAPER-MAKING MACHINES.

Specification of Letters Patent.

Patented Sept. 17, 190-7.

Application filed October 13,1906. Serial No. 338,797.

To all whom 'it may concern:

Be it known that I, WILLIAM F. PicKLEs, a citizen of the United States, and a resident of Buckland, in the .county of Hartford and State of Connecticut, have invented a new and Improved Regulator for Paper-Making Machines, of. which the following is a specification.

My invention relates to the class of devices for regulating the heat supply to a cylinder or the cylinders of paper making machines, and the object of my invention is to provide a device of simple construction which will effectively accomplish the purpose in view; and a further. object of the invention is to provide a device of this class that shall readily and quickly respond to the forces upon which it depends for operation.

A, form of device in the use of which these objects may be attained is illustrated in the accompanying drawings, in which- Figure l is a view inside elevation of a portion ofa paper making machine showing my invention applied thereto. Fig. 2 is a detail view in cross-section' through the machine showing one end thereof and a portion of the opposite end, the center being broken out.

In the accompanying drawings the letter a denotes 4the frame of the machine, b the cylinders suitably mounted thereon, c a supply pipe for a heat medium for said cylinders, d delivery pipes to the cylinders, e a valve for controlling the supply of the heat medium, f apron rolls for supporting the Wire or apron as it travels in the machine, andg web rolls for supporting the web of paper as it travels through the machine. All of the parts above described may be of well-known form and construction and a further detailed description is therefore deemed unnecessary herein, as the method of operation -will be readily understood by those skilled in the art merely from an examination of the drawings. The web rolls, in the ordinary construction o such a machine proper, are rigidly mounted on the frame, but I have ascertained that by mounting one roll so that it may have other than a rotatable movement in its bearings such movement may be utilized in the Operation of a device for regulating the supply of heat or` of a heat medium to the cylinders. Such a device is illustrated and described in my United States patent dated July l0, 1906, No. 825,612, to which reference is hereby made for such understandingof the invention as may not be obtained herefrom.

The numerai 5 indicates bracket arms rigidly secured to the machine frame, 6 pivots secured to said'arms, 7 movable web roll supports pivotally sustained by said pivots, 8 a web roll mounted in said supports, 9 a link extending from the supports to a regulator frame l0, pivotally mounted on the machine frame, ll a regulator shaft mounted on the regulator frame, 12 a ratchet wheel secured to said shaft, and 13 a pin eccentrically mounted in the end of a shaft hereinafter mentioned. All of the parts just mentioned and designated by 11urnerical characters are shown and described in my patent above named. The numerals from 20 upward are hereinafter employed to designate the parts forming novel features herein.

The numeral 2O indicates 'a shaft extending across the machine from side' to side and driven as by means of a belt 21 passing from a pulley 22 on the shaft of one of the web rolls g to a pulley 23 secured to the shaft 20. The pin 13 is revolved or eccentrically moved by means of this shaft 20 to which it is secured. Bearings 3() are formed on the frame of the machine within which a sleeve 3l extending across the machine is mounted. The shaft 20 extends through and is rotatably supported in the sleeve 3l and arms 32, keyed to this sleeveat opposite ends, extend upward and are pivotally connected by the link 9 with the movable web roll supports 7, so that swinging ymovement of the web roll is communicated to the arms 32.

A slide support 33 is formed on the regulator frame l0v within which is located la slide 34. The lower end of this slide has an opening or slot 35 for the reception of the pin I3. To this slide, preferably at its lower end, a pawl 36 is pivoted. This pawl is forked, its branches lying on opposite sides of the ratchet l2, and the ends of the branches being formed to engage the face ratchet teeth formed on the opposite sides of the ratchet, said teeth being inclined in opposite directions as shown.

The shaft l1 bears a movable member consisting of a worm 37 meshing with a'worm wheel 38 about the hub of which a llexible connection h is wound, said connection extending to the valve lever i of thevalve e.

The pawl 36 is engaged and disengaged from the ratchet wheel by means of a part located inthe path of movement of a part on the regulator frame l0. The means herein shown for accomplishing this result consists of an arm 40 from the pawl 36 extending between pins 39 on the face of the support 33. These pins are preferably located in sliding engagement with the arm 40,l so that the latter may freely move in the reciprocation of the pawl, but the least movement of the frame l() will be imparted to the arm 4() and hence to the pawl 3G. I

From the above description the operation of the device will be readily understood, the roll 8 moving to the right or left, as seen in Fig. l, under the expansion or contraction of the-web lc caused by the decrease or increase of heat in the cylinders. Supposing the cylinder to be heated beyond a degree required to secure proper drying of the web, such web will contract and canse the roll 8 to be swung to the left. This movement will swing the regulator frame l0 on its pivot, carrying the upper portion to the left, and by engages ment of the pins 39 the arm 40 from the pawl 36 is carried to the left swingingthe left branch of the pawl into engagement with the ratchet wheel I2. As the pawl moves downward in its reciprocating movement it heat to the cylinders.

l causes the ratchet 12 and shaft 1l to be rotated in the direction of the arrow shown in Fig. 2. The Worm'37 being a right-hand Worm the Worm Wheel 38 is rotated in the direction of the arrow in Fig. 1, causing the Connection h to be wound upon the hub of the Worm wheel 38 thus closing thevalve e and reducing the supply of Should the Webbe insuliciently dried the operation of the parts above described is reversed.

It will be noted', as shown by the drawings herein, that the shaft l1 is located on the back ol' the regulator frame, the ratchet wheel 12 projecting through an opening in the regulator trame.
