Application filed April 17, 1856. Serial No. 199,198. (No model.)

To all whom it may concern.-

Beitknown that I, ABRAM A. RHEUTAN, of Vorcester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Mechanical Movements; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which Figure 1 is a side View, partly in section, of my invention. Figs. 2, 3, and 4 represent skeleton side views thereof with the various parts in different positions to more fully illustrate the operation of said mechanical movement. Fig. 5 represents a plan view of my invention, showing said invention applied to a feeding device for automatically feeding forward sheets of paper or similar articles, as hereinafter more fully described; and Figs. 6, 7, and 8 are skeleton side views of my invention, representing its application aforesaid as a feeding device, the various parts being shown by full and dotted lines in different positions to more fully illustrate the operation thereof hereinafter described.

My mechanical movement consists of a roeking cam-lever pivoted between its extremities, a locking device at each end of said lever, a yielding body traveling within the are of oscillation of said carn-1ever and between said locking devices in first one and then the opposite direction, and adapted to bear against the cam-lever or parts thereof, .whereby the said traveling body at each end of its reciprocation will cause the cam-lever to be unlocked atone end and locked at the opposite end, thereby removing out of the line oftravel of said traveling body one part of the cam-lever and bringing within its line of travel another part of said lever, as hereinafter described. Incidentally, too, a force or power may be accumulated within the said traveling body, and such force or power may be released within the limit of oscillation of the cam-lever, and the said force or power when created or released may be used for any useful effect.

Hy invention when in practical operation is capable of imparting a pressure or draft power to any mechanism connected therewith, as hereinafter described, either in a vertical,

horizontal, or any other plane, according to the positions occupied by the various parts comprising said invention. It is designed more especially, however, to be applied to use as a feeding device, and that others may fully understand its nature and application to prac tice I have shown and described the same as being thus applied, both in the drawings and the following specification thereof, said ap plieation serving to illustrate one of the many ways in which the power imparted from the device embodying my mechanical movement may be utilized when applied to practice.

To enable those skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe it more in detail.

Referring to the drawings, the part marked A represents the cam-lever hereinbefore referred to, having in this instance the cam-surfaces A A upon the under side of each end thereof, and pivoted at its center to the stationary bearing A extending up from the bed H. Any other form of lever may be employed to produce the result hereinafter described, and it may be pivoted at any point between its extremities instead of as above described, if desired, without departing from the principle thereof. Both ends of the lever A are arranged to be alternately locked when in a depressed position, as hereinafter described, by means of the swinging dogs B O, hinged at their upper ends to the stationary bearings 13* O", and provided with the notches or shoulders B 0, against which the ends A A" of the lever A bear when depressed so as to come under thesame. A constant forward pressure is imparted to the swinging dogs B O to hold the latter against the ends of the lever by means of their own weight or the springs B 0, one end of said springs being fastened to the pivots of said dogs, while their other ends are arranged to bear against the outer sides of the pins (4 a, fastened in the dogs. Therefore it is obvious that when one of the ends A of lever A is under its respective notch B or C it is held in said locked position until released therefrom by pushing back its holding-dog and forcing up said end of the lever, as hereinafter described, the latter operation, as will also be seen, causing the opposite end of the lever to be depressed and looked, as above described.

The cam-surfaces A A, hereinbefore referred to, are formed in this instance bymaking the lever A bow-shaped, the pivot of said lever being arranged above the level of the holding-notches B (3 to accomplish said result; One end of the lever is unlocked and forced up, so as to depress and lock the opposite end thereof, as hereinbefore stated, by means of a body having a forward and backward reciprocating movement, and adapted to travel and press against said lever upon the opposite side of the holding notches or shoulders of its locking devices hereinbefore described. The above operation is performed by said traveling body striking and forcing back the swinging dog which comes in front of its line of motion, and thereby releasing the lever, which is at once forced up and its opposite end consequently forced down or depressed below the holding-notch of its dog, thus locking the same by the springing forward of said dog, as hereinbefore described. It is obvious'that by thus locking one end of the lever by the operation of unlocking its opposite end a rigid cam-surface is brought in the path traveled by the moving body at each reverse movement thereof between the ex tremities of the lever, thereby causing said body to be depressed at each of said reverse movements, and the lever to be alternately rocked in first one and then the opposite direction, so long as the reciprocating movement of the body is continued. Any desired movement or movements may be imparted from the lever to said traveling body as the latter trav-, els over the hearing or cam surfaces thereof by varying the contour of said surfaces to correspond to the motion or motions desired to be obtained. The pivot of said lever may also be varied to one side or the other of the center, if necessary, to produce the desired result.

Power may be transmitted from the device by connection with either the lever or the traveling body, and said device may be arranged to operate in a vertical or any other angle or plane than that shown in the drawings, so as to transmit motion therefrom in any desired direction. Said motion, it will be understood, always being either a pressure or draft power, which it is obvious may be utilized in an innumerable variety of ways ingoperating different kinds of devices and machinespr parts thereof-as, for instance, it maybe ni ployed for operating the cut-off of a steam-,

engine by connection therewith in any suitable and convenient manner, It may also be connected with a rack or lever having a pawl for operating a gear or ratchet wheel, respectively, to in turn operate mechanism connected therewith; or it may be used for operating a shipping-lever connected with mechanism requiring to be started up and stopped alternately at regularintervals. Still another use to which said power may be applied is to engage and disengage one gear to and from another for producing an intermittent motion to mechanism connected with the driving-gear.

Many other ways of applying the power produced by my mechanical movement may be adopted in addition to those above described.

In the present instance I have represented the traveling body hereinbefore described by means of a cam-roll, D, which is mounted on a stud formed upon the crank-arm D of a'horizontal shaft, G. Said roll is arranged under or in line with the rock-lever A, and is held against the cam-surfaces A thereof by means of a spring, D, one end of which is fastened to the shaft G or passed around said shaftand arranged to bear upon the top of carriage G, as shown, while its other end bears upon the under side of a pin, b,fastened in the crank-arm. The shaft G is fitted to turn in bearings G G, extending up from said carriage G, and

the latter is fitted to slide forward and back alternately in first one and then the opposite directionin suitable ways or guides formed in the table or bed H, as shown in Figs. 1 and 6. The aforesaid reciprocating motion may be imparted to carriage G in any well-known way, according to the nature of the device or machine to which my invention is applied.' Ordinarily levers J, the upper ends of which are shown in Fig. 5, would be employed for that purpose, the same being connected directly with or by means of links J with said carriage, as is also shown in said Fig.5.

In the first four figures of the drawings I have shown only such parts as are necessary to illustrate the practicability of my mechanical movement, while in the last four figures I have shown in addition thereto such parts as are necessary to illustrate the application of said invention to a feeding device, this being one ofthe main purposes for which the invention is designed in practiceviz., for feeding paper, envelopes, and other articles of a similarnature in the usual operation of printing, manufacturing, or otherwise operating upon the same. v

In the drawings the feeding device is designed for feeding forward sheets of paper I from a pile of paper, I, placed in front of the gripping-jawsK of said device. I have shown three sets of said jaws. The lower half or arm, F, of each jaw is made rigid upon the carriage G, while the upper parts, E, thereof are fastened to the rock-shaft G. Therefore it is obvious that when the carriage is moved s-forward and back, as hereinbefore described, the'upper arms, E, being operated by the lever A through the cam-roll D crank-armD, and shaft G", the jaws are alternately closed and opened to grip and release the sheet of paper I in feeding the same forward, as hereinafter described and shown in the drawings.

The operation of feeding forward a sheet of paper, I, by means of the aforesaid feeding device may be briefly summed up as follows: Assuming that the left-hand end of lever A is locked, as shown by full lines Figs. 1, 4, and 6, and dotted lines'Fig. 8, and that the car- 'rro riage G and parts mounted thereon are moving from right to left toward said locked end of the lever, the jaws K being at this time closed, by a continuation of said movement toward the left the cam-roll D comes in contact with the cam-surface of said lever, and is forced down as it continues to move forward, thus depressing the crank-arm D, and in con sequence turning the shaft G a partial revolution,which operation, as will be seen, causes the outer ends of the arms E (constituting the upper parts of the jaws) to be raised above the stationary arms F on the carriage, thereby opening said jaws K to receive the sheet of paper 1. The latter may be raised from the pile I, so that the jaws may grasp it, or not only raised, but fed forward between the jaws in any well-known way. As it matters not what way is adopted in practice to produce said result, and the same constitutes no part of my invention, I have simply shown the positions of said paper in the drawings.

In Fig. 6 I have illustrated by dotted lines the jaws as being open with the sheet of paper to befed forward between the upper and lower parts of said jaws. As the carriage continues to move forward when the cam-roll comes in contact with the locking-dog B, the latter is pushed forward and disengaged from the end of the lever, thus allowing said roll to be sprung up, when the jaws K are then closed upon the paper, as hereinbefore described and shown in Fig. 7 of the drawings. The above operation not only closes the jaws K, but also by forcing up the end of the lever causes the opposite end thereof to be locked, as also hereinbefore described and shown in Figs. 2, 3, 7,and 8, thus bringinga rigid cam-surface in the line of travel of the cam-roll when reversed. Said reverse or return motion now takes place and the paper is drawn forward from the position shown by full lines to that shown by dotted lines in Fig. 7, where it is left by the.

jaws again opening and releasing the same by the cam-roll coming in contact with and being forced down by the rigid cam-surface at this end of the lever, as shown by full lines, Fig. 8. The roll shown by full lines in said figure is represented as having arrived at the end of the lever in its movement toward the right and just ready to unlock said end of the lever. As it continues to travel forward, it pushes forward the dog 0, and thereby performs said unlocking operation, as in the former instance, at the opposite end of the lever. The movement of the carriage G is now again reversed toward the left,when the closed jaws are moved forward to grasp and feed forward the next sheet of paper, as hereinbefore described, and so on continuously for each succeeding sheet of paper. As the closed jaws move back for the next sheet, as aforesaid, they pass under the sheet previously fed forward, as shown by dotted lines in Fig. 8, the forward ends of said jaws being beveled back, as shown, to facilitate said operation.

Any convenient way may be adopted for controlling the movements of the lever A when unlocked, and its ends are sprung up by the cam-roll, as hereinbefore described. In this instance I have shown two stops, L L, for the above purpose arranged one upon each side of the pivot of said lever. (See Figs. 1 andG.)

Having described my improved mechanical movement and one application thereof, what I claim as new and of my invention, and desire to secure by Letters Patent, is-

A mechanical movement comprising a rocking cam-lever pivoted between the. extremities thereof, and adapted to be alternately unlocked and locked at first one end and then the other by means of suitable locking devices, in combination with a traveling body having a reciprocating movement between said lever-locking devices adapted to unlock the latter and to press against the surfaces of the lever, substantially as and for the purposes set forth.
