Application filed March 28, 13114. Serial No. 827,925.

To all whom it may concern:

Be it known that I, Gnoncn M. JOHNSTON, a citizen of the United States of America, residing at Vandergrift, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Sheet Separating Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to metallic sheet separating machines and has for its object to provide means, in a manner as hereinafter set forth, for separating a pair of metallic sheets which have been secured together during the rolling operation, and to overcome the necessity of manually separating the sheets, which is now in general Vogue, and which requires considerable time.

Further objects of the invention are to provide a sheet separating machine which is simple in its construction and arrangement, strong, durable, efficient and convenient in its use, readily set up and comparatively inexpensive to manufacture. WVith the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more fully described and illustrated in the accompanying drawings, wherein is'shown an embodiment of the invention, but it is to be, understood that changes, variations and modifications can be restorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail, reference is had to the accompanying drawings wherein like reference characters denote corresponding parts throughout the several views, and in which Figure 1 is a front elevation of a metallic sheet separating machine inaccordance with this invention; Fig. 2 is a section on line XX Fig. 1, looking in the direction of the arrow; Fig. 3 is a view looking toward one end of the separating rolls, these latter being broken away; Fig. 4 is a vertical sectional view, broken away, of the separating rolls; Fig. 5 is asectional plan of one-half of one of the separating rolls, the roll being broken away, and Fig. 6 is a detail of a modified form illustrating a bearingfor the lugs or shafts for theclamping members. Referring to the drawings in detail, 6 denotes the base and 78 the sides of the housing, and journaled in the sides 78 is an upper and a lower separating roll shaft, the latter being intermittently rotated. The upper shaft is indicated at 9, and the lower shaft at 10. The shaft 9 projects from the side 7 and carries a gear 11, and the shaft 10 projects from the side 7 and carries a gear 12', which meshes with the gear 11. The shaft 10 is connected to a prime mover, not shown, for driving it intermittently, and motion is transmitted to the shaft 10; the shaft 9 is also driven owing to the gear connections 11-12, but the shaft 9 will revolve in an opposite direction with respect to the direction of the revolution of the shaft 10. FiXedly secured to the shaft 9 is an upper separating rolls 13, and fixedly secured to the shaft 10 is a lowerseparating roll 14. The rolls lit-14 are arranged in parallelism, and as the rolls are constructed alike, but one will be described, as the description of one applies to the other. Each of'the separating rolls has its body portion formed with a longitudinally extending V-shaped pocket 15, of less length than the length of thebody of the roll, and the ends of the pocket 15 are arranged inwardly with respect to the ends of the body of the roll. Each of the rolls is furthermore provided with. a longitudinally extending slot 16 which opens into thepocket 15, and is of less width than the mouth of the pocket, the mouth of the pocket being of greater width than the bottom of the pocket. The slot 16 provides what may be termed a pair of oppositely disposed shoulders 1718,

and each of said shoulders are rounded and extend the length of their respective pocket 15; in fact, the shoulders 17-18 are formed from portions of the top wall of the pocket 15. TvVhenthe rolls 1314: are set up, the pockets 15 extend in opposite directions with respect to each other, and the slot 16 of one roll opposes the slot 16 of the other roll.

- Arranged within each of the pockets 15, and mounted against the shoulders l718 is a pair of oppositely disposed clamping members 1920, and each of which is of a length equal to the lengthof its respective pocket. One end of each of theclamping members is provided with a lug 21 which is seated in its respective roll, and the other end of each of said members has fixed thereto a stub shaft 2:2, which projects from the roll as at 23 and carries a toothed quadrant. The quadrants carried by the shafts'22 of the members 19 are indicated at 24, and the quadrants carried by the shafts 22 of the members 20 are indicated at 25. The quadrants 2 1 are oppositely disposed with respect to the quadrants 25, and said quadrants 2i permanently mesh with the quad rants The normal position of the clamping members carried by the roll 13 is upwardly at an angle with respect to their quadrants, and the normal position of the clamping members carried by the roll 14- is downwardly at an angle with respect to their quadrants.

Each of the quadrants 2 1 is provided with a pair of apertured lugs 26, and to one pair of lugs 26 is pivoted link 27, which is pivotally attached to a pair of lugs 28, carried by a sliding collar 29, mounted upon the shaft 9; and the other pair of lugs 26, has pivotally connected thereto a link 30, the latte being pivotally connected to a pair of lugs 31, carried by a shiftable collar 32, mounted upon the shaft 10. Each of the collars 29 and is provided with a pcripheral groove 33, and arranged in each of said grooves is a strap 3 and the said straps 3% have connected thereto a vertically disposed coupling member 35, having a lengthwise extending slot 36.

Carried by the inner face of the side 8 is a bracket 3?, in which is pivotally connected a yoiie-shaped shifting member 33; the latter extends through the slot 36. The member 33 is provided with a crank arm 39, having pivotally connected therewith the upper end of a pulling rod 10, the latter having its lower end pivotally connected as at 11, to a spring controlled pivoted foottread d2. The normal position of the member 38 is at an upward inclination whereby when said rod =10 is pulled downwardly, the action of the member 33 will. be such as to shift the coupling member 35 toward the rolls, and said member 35 will carry the collars 29 and 32 therewith. As the collars 29 and 32 are moved toward the rolls 13 and 14L, the links 2730 will be simultaneously actuated, moving the quadrant 2 1 carried by the roll 13 downwardly, and the quadrant 2 f carried by the roll 13 upwardly, and by such movement of the quadrants 24, a like movement will be imparted to the quadrants owing to the fact that the quadrants 2 1 mesh with the quadrants 25. When the quadrants carried by the roll 13 are moved downwardly, the clamping members within said roll are also moved downwardly, and when the quadrants of the roll 14 are moved upwardly, the clamping members within said roll 14: are also moved upwardly, or in other words when the quadrants are shifted by moving the collars 29 and 32 toward the rolls 131ei, the clamping members of each roll are shifted toward each other. The clamping members of each roll are utilized for connecting the ends of the metal sheet therewith, as indicated at 4-3 i 1, whereby when the rolls 1314c revolve, a pair of secured sheets, as indicated at 15, are separated. The ends 13 1 1 of the pair of secured sheets are first separated by hand and extended into the pockets so that they can be engaged by the clamping members when the collars 2932 are shifted toward the rolls 131 l-. The length of the sheets to be separated is slightly less than the circumference of the separating rolls. The clamping members are maintained in engagement with the ends of the sheets 43H, as long as pressure is applied to the foot-tread 42. When pressure is released from the foot-tread 1-2, the spring 16 restores said tread 12 to normal position, and during such action the collars 2932 are shifted away from the rolls 1314t due to the action of the member 38 with respect to the coupling member 35.

In Fig. 6 of the drawings, a modified construction is set up relative to the manner of supporting the lugs or shafts of the clamping members 19 and 20. Each of the rolls, which is indicated at 51 is provided with a pocket 18, which corresponds to the pocket 15, but the said pocket 18 is of a length equal to the length of its respective roll. Each of the rolls 51 is provided at each end with seats 52, upon which are mounted flanges 4-9, and the bearing plates 45 which are seated in the pockets at the ends thereof are flush with the ends of their respective roll 51. The flanges 19 are fixedly secured to their respective roll 51 by holdfast devices 50. The bearing plates 46 are provided with openings 17, in which are seated the lugs or shafts 21 for the clamping members 19 and 20. The lugs or shafts 21* at one end of the clamping members are flush with one end of the roll. 51 and the lugs or shafts 21 at the other ends of the clamping members a are projected and have the quadrants 21 and 25 mounted therein. The bearing plates 16 are flush with the ends of the rolls and the top edges of the bearing plates 4-6, as well as the top edges of the flanges 49 forming a continuation of the periphery of the roll 51.
