DEVICE FOR WEIGHTING ROLLS IN TEXTILE 0R ANALOGOUS MACHINES.
SPECIFICATION formingpart of Letters Patent No. 632,947, dated September 12, 1899.
Application filed April 3, 1899. Serial No. 711,611. (No model.)
To aZZ whom/ it may concern.-
Be it known that I, FRANKLIN P. RAND, a citizen of the United States, residing in the city and county of Providence and State of Rhode Island, have invented a new and useful Device for Weighting Rolls in Textile or Analogous Machines, of which the following is a specification.
My invention is applicable to all textile and analogous machines in which the character and quality of the product is dependent in any wise upon the degree of pressure maintained between the rolls which immediately act upon the material of which such product is composed.
Heretofore in textile machines in which the material operated upon passes between rolls in the process of manufacture under a greater or less amount of pressure, dependent upon the character or quality of the product to be obtained, such pressure has been secured by the use of metal weights suspended from the top roll or rolls, the amount of pressure between the rolls being determined by the avoirdupois of the weight used. Such arrangement has necessitated the keeping on hand as a part of the machine equipment of a number of weights of different avoirdupois.
The purposes of my invention are to provide in textile and similar machines a compact and inexpensive means for readily adjusting and regulating the pressure of the rolls without the use of weights and forchanging the degree of pressure at will. I accomplish the end desired by the novel construction, combination, and arrangement of parts hereinafter described and shown in the accompanying drawings, in which Figure l is a front elevation illustrating the manner of applying my invention to the front rolls of a machine. Fig. 2 is a section on the line at so of Fig. 1, showing also the application of my invention to the rear rolls of a machine. Figs. 3 and 4 are detail views.
Similar reference -numerals indicate like parts where they occur in the drawings.
In the drawings I have shown simply a portion of the beam, the front and rear rolls, and their stands as the same are ordinarily arranged in a textile machine, asI consider this sufficient to properly illustrate and explain the construction, application, and operation of my invention. I have also shown my invention as applied to the rear as well as to the front rolls of such machine.
1 represents the beam of the machine upon which are secured in the well-known manner stands 2 2, in which are journaled in the usual way the front top and bottom rolls 5 and 6 and the rear top and bottom rolls 7 8 and 9 10.
The form of my invention as applied to the front rolls consists of a strap 11, provided at one end with a shank terminating, preferably, in a headed or enlarged portion, to.
which is secured one end of a coil-spring 12, and at its upper end terminating in a hook 11, adapted for engagement with the top roll, Figs. 1 and 2. 13 represents a strap provided at one end, preferably, with an enlarged or head portion 13', to which is secured the opposite end of said coil-spring 12, and at its opposite end, preferably, with an eye 13 adapted for engagement with a toothed or serrated hook 14, secured upon the beam 1. Said teeth are out upon an incline and so graduated from pointto back of the hook that by moving the eye 13 into engagement with one or another of said teeth the tension of the spring 12 can be increased or diminished, and thereby pressure equivalent to the weight required for the particular work in hand be brought to bear upon the top roll. For convenience in adjusting the eye 13 in the teeth of the hook 14 I provide laterally-extending thumb-holds 14 14 The rear rolls because of their location in the machine are not so readily accessible as are the front rolls. I have therefore found it more convenient to use the form of hook shown in Figs. 2 and 3, in which the hook 15 overhangs its body portion, which is provided with an elongated slot 15 and is adjustably secured upon the beam 1 by a bolt, as 16, passing through said slot and into the'beam 1. I also for convenience of use in connection with the rear rolls modify the upper strap of the device by making said strap in flattened form, as 17, and providing the same with an eye 17, through which is passed the well-known saddle 18, which, as commonly used, rests upon two rear top rolls, Fig. 2.
The spring 12 is normally in the closed position, as shown in Fig. at, and is distended when the device is in engagement with the rolls and serrated hook, Figs. 1 and 2. The serrated book being graduated as to its teeth, as before stated, so that the tension of the spring 12 is increased or diminished as the strap 13 is caused to engage with one or another of said teeth, pressure equivalent to the force of said tension is brought to bear upon the rolls. In other words, the engagement of my invention with the rolls and serrated hook puts the spring under tension, thereby storing in said spring energy, which by means of the hook is so graduated as to maintain the required pressure between the rolls.
1 claim as my invention- 1. In a textile or analogous machine in which the character or quality of the product is dependent upon the degree of pressure maintained between rolls which act formatively upon the material entering into said product, the combination with the top rolls and beam of such machine of a strap provided at one end with means for engagement with the top rolls, a second strap provided at one end with means for engagement with a serrated hook secured upon the beam of the machine, a coil-spring arranged to serve as a yielding spring connection between said two straps, and a graduated serrated hook secured upon the beam of said machine, and adapted to serve as a means for storing energy in said spring, and also as a means for graduating such energy to maintain the required pressure upon the rolls.
