TRIMMING-IVIACHINE FOR ROLLS.

` Specication of Letters Patent.

Patented May 11, 1915.

Application led May 8, 1914. Serial No. 837,296.

T0 all whom t may concern Y Be it known that I, MILLARD F. ANDER- soN, a citizen of the United States, and a resident of the city of New York, Belle Harbor, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Trimming-Machine for Rolls, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved machine for simultaneously trimming both ends of a roll of oilcloth or other material, and arranged topermit convenient adjustment of the knives or cutters for trimming rolls of diierent length.

In order to accomplish the desired result use is made of a driven supporting roller for supporting a roll and rotating the same, a driven abutment roller for one side of the roll to abut against, spaced rotary knives or circular cutters for cutting the ends of the roll, and means for moving the said rollers and the said knives bodily one relatively to the other.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in

which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the trimming machine; Fig. 2 is a plan view of the same; Fig. 3 is a front elevation of the same; Fig. t is an enlarged cross section of the carriage and its bearing on the main frame; Fig. 5 is an enlarged plan view of the adjustable roller` on the carriage; Fig. 6 is a cross section of the same on the line 6-6 of Fig. 5; and Fig. 7 is an enlarged cross section of one of the revoluble knives or cutters and its mounting. p

The improved trimming machine is mounted on a suitably constructed frame A provided with fixed bearings A in which is journaled a shaft B provided at its ends with adjustable and revoluble circular cutters or knives C for trimming the ends of a roll D of oilcloth or other material, as hereinafter more fully described.

The roll D is supported on one or a series of rollers E, and one side of the roll D rests on or abuts against one of the series of abutment rollers F, the said rollers E and F driven in the direction of the arrows in Fig.

1 to rotate the roll D, and on moving the carriage Gr rearwardly the roll D is carried along with the rollers E and F and is hence fed to the rotary knives or cutters C to trim the ends of the roll D.

In order to hold the roll D in place on the supporting rollers E and the abutment rollers F use is made of one or a series of bearing rollers H attached to a shaft H journaled in suitable bearings arranged on a swing frame Ifulcrumed on a shaft J journaled in suitable bearings arranged on the rear end of the carriage G. The forward end of the swing frame I is provided with ahandle I adapted to be taken hold of by the operator to swing the forward end of the frameI downward with a view to move the bearing rollers H in engagement with the top of the roll D to hold the latter in position during the trimming operation by the knives or cutters C. The rear end of the swing frame I is provided with a counterweight I2 to hold the swing frame I with its forward end normally in a raised position, as indicated in full lines in Fig. l, to permit of conveniently placing the roll D in position on the supporting rollers E and the abutment roller F, or for removing the trimmed roll D from the said rollers E and F.

In order to rotate the rollers E and F and the knives or cutters C prior to moving the carriage G rearwardly with a view to feed the roll D to the said knives or cutters the following arrangement is made: On the main frame A is mounted a motor K of any approved construction and provided on its shaft with a pinion K in mesh with an intermediate gear wheel K2 secured on a shaft v A members K5 and L to normally hold the clutch member L out of engagement with the clutch member K6 to allow the gear wheel K5 to rotate loosely on the shaft L.y

The clutch member L is engaged by a shifting lever L3 fulcrumed at its lower end at L4 on a suitable bracket attached to the floor and the upper end of the said shifting lever L3 is connected by a link L5 with one end of a coil spring L6 connected at its other end with an arm L7 projecting upwardly from a pedal shaft N journaled in suitable bearings arranged on the main frame A. On the pedal shaft N is secured a pedal N under the'control of the foot of the operator standing in front of the machine so vthat when theV pedal N. is pressed downward a short distance then a rocking motion is given to the shaft N to cause the arm L7 to exert a pull on the spring L6 which by the link L5 imparts a swinging motion to the shifting lever L3 to move the clutch member L into engagement with the clutch member K6 to cause the gear wheel K5 to rotate the shaft L by the engaged clutch membersKG and L. When the operator releases the Apressure on the pedal N, the spring L2 forces the clutch member L out of engagement with the clutch member K6 to stop the further rotation of the shaft L. On the shaft L is secured a sprocket wheel O con-A nected by a sprocket chain O with a sprocket wheel O2 secured on the shaft J previously mentioned, and on the said shaft `J is secured a sprocket wheel J connected by a sprocket wheel J2 with sprocket wheels J3, J4 secured on the shafts E and F respectively, so that when the shaft L is rotated a rotary motion is given to the rollers E andv F to rotate the same in the direction indicated by the arrows shown in Fig. 1. As the shaft J above mentioned is journaled on the carriage G the sprocket chain O has to be kept taut by the use of a tightening sprocket wheel O3 in mesh with one of the runs of the sprocket chain O, the said sprocket wheel O5 being journaled on an arm O4 fulcrumed on the main frame and pressed on bya' spring O5 to cause the sprocket wheel O3 to bear against the chain O with a view to hold the same taut.

On the shaft L is secured a sprocket wheel P connected by a sprocket chain P with a sprocket wheel P2 secured on the shaft B so that when the shaft L is rotated as previously explained then a rotary motion is transmitted by the sprocket wheels P and P2and the sprocket chain P to the shaft B to rotate the knives or cutters C in the direction of the arrows indicated in Fig. l.

In order to impart a reciprocating motion to the carriage G with a view to feed the roll D past the cutters or knives C, the following arrangementy is made: On the shaft L is secured a pinion Q in mesh with a gear wheel Q mounted to rotate loosely on a cam shaft B journaled on the main frame A. On one face of the gear wheel Q (see Fig. 3) is secured or formed a kclutch member Q2 adapted to be engaged by a clutch member Q3 mounted to slide on and rotate with the shaft R. A spring QL is interposed between the clutch members Q2, Q3 to normally hold the clutch member Q3 out of engagement with the clutch member Q2. By reference to Fig. 3 it will be noticed thatfnormally the clutch member Q3 is held a greater distance apart from its clutch member Q2 than the distance between the clutch members Land KG. The clutch member Q3 is controlled by a shifting lever Q5 fulcrumed at QG on the main frame A, and the said shifting lever Q5 is pivotally connected by a link Q7 with an arm QSS depending from the pedal shaft N. Now when the pedal N is pressed a short distance downward then the clutch member L is moved in engagement with the clutch member K5, but when this takes place the clutch member Q3 is close to but is still out of engagement with the clutch member Q2, and on further downward pressing of the pedal N the clutch member Q3 is moved into engagement with the clutch member Q2 so that the 'shaft R is driven from the gear wheel Q now driven by the pinion Q from the now rotating shaft L.

It will be noticed that after the clutch members L and K6 are in engagement and the pedal N is further pressed downward then the spring L6 is expanded to allow a downward movement of the pedal lever N to move the clutch Q3 into engagement with the clutch Q2.

On the cam shaft R is secured a cam R engaging with its peripheral face a friction roller R2 held on the lower end of a shifting lever R3 fulcrumed at R4 on the main frame A. The upper end R5 of the shifting lever R2 is in the form of a fork engaging a friction roller S adjustably mounted on a bracket S attached to the carriage G so as to move with the same. The friction roller S has its stud S2 (see Figs. 5 and 6) provided with a head S7 and a square offset S4 fitting into a slot S5' formed in the bracket S. In the head S3 screws a screw rod S5 journaled in bearings S7 attached to or forming part of the bracket S so that when the screw rod S6 is turned by the operator then the head S3 is moved longitudinally on the bracket S to move the friction roller S into a desired position to hold the rollers E and F in proper position relatively to the knives or cutters C according to the diameter of the roll D to be trimmed at the time.

A nut and washer Ss are held on the threaded extension S9 of the square offset S4 to fasten the head S3 inlplace on the shaft i S after the desired adjustment is made. The shifting lever R3 is provided with an angular arm R6 (see Fig. l) connected at its free end with one end of a spring R7 attached at its other end to the main frame A so as to impart a return swinging motion to the shifting lever R3 at the time the friction roller R2 drops off of the end of the cam R as will be readily understood by reference to Fig. l.

The carriage G is provided at the under side o-f each of its side arms with an integral bar Gr', provided at the under side with bevels G2 and G3 extending in opposite directions and engaging conical rollers T and T contained in the U-shaped guideway A2 and having their shaft T2 journaled in a bearing T3 provided with a pin T4 engaging a socket A3 formed in the bottom of the guideway A2. By this arrangement an easy forward and backward sliding movement of the carriage Cr is had, it being understood that the guideways A2 are preferably filled with oil to keep the carriage Gr properly lubricated.

By reference to Fig. 2, it will be noticed that the bearings A for the shaft B are intermediate the two knives or cutters C to allow shifting of the knives or cutters C on the ends of the shaft B with a View to move the knives or cutters C the desired distance apart according to the length of the roll D to be trimmed at the time.

In order to allow convenient shifting ofeach cutter or knife C on the shaft B and to securely fasten the same in position on the shaft after the desired adjustment is made the following construction is provided, special reference being had to Fig. 7: Each knife or cutter C is clamped between'ilanges C, C2 of which the flange C is fiXed on the hub C3 while the flange C2 screws on a threaded portion of the hub C3 and is locked in place by a jam nut C4 screwing on the hub. The hub C3 has a conical bore and its onto a conical split sleeve C5 fitting the shaft B, and the small end of the sleeve C5 is threaded and on this threaded portion screws a nut C abutting against the small end of the hub C3. On screwing up the nut CG the hub C3 is pushed up on the sleeve C5 whereby the hub is tightened on the shaft B and is consequently clamped thereto, and at the same time the hub C3 is drawn tight on the conical sleeve C5. When it is desired to change the position of a knife or cutter C it is only necessary to ypartly unscrew the Y nut CG to release the hub C3 which in turn place on the sleeve C5 on the shaft B. When it is desired to remove av knife or cutter C from its hub C3 for grinding or other purposes then the nut C4 and the flange C2 are unscrewed from the hub C3 to allow removal of the knife or cutter C.

The operation is as follows: l/Vhen the carriage G is in forward position and the swinging frame I is in uppermost position then the operator can conveniently place a roll D to be trimmed in position on the rollers E and F so that the roll D is in front of the knives or cutters C. The operator now takes hold of the handle I andV swings the frame I downward so that the bearing rollers H engage the top of the roll D. The operator now presses the pedal lever N downward so that the shifting lever L3 moves the clutch member L in engagement with the clutch member KG to cause the continually rotating gear wheel K5 to rotate the shaft L. As soon as the shaft L is rotated a rotary motion is given to the rollers E and F and the knives or cutters C and then the operator presses the pedal-lever N still farther downward to cause the clutch member Q3 to engage the clutch member Q2 so that the cam shaft R is now rotated. The rotary motion of the( shaft R causes its cam R to impart a swinging motion to the shifting lever R3 whereby the carriage G is moved thereby carrying the rotating roll D along and thus feed the same to the knives or cutters C.` The knives or cutters now trim the ends of the roll'D, it being understood that the vtrimming operation is completed when the friction roller R2 drops off the end of the cam R, and the carriage G is now returned by the action of the spring RT imparting a return swinging motion to the shifting lever R3. As soon as the carriage G reaches it forward position the operator swings the swing frame I upward and then removes the trimmed roll D from the rollers E and F and places another untrimmed roll in position thereon. The above described operation is then repeated.

It is understood that as the roll D is rotated by contact with the driven rollers E and F it is evident that the carriage G needs to be fed only a distance slightly in excess of half of the diameter ofthe roll D. By adjusting the friction roller S on Vthe bracket S, as previously explained, the carriage Gr may be moved farther outward or inward to suit the diameter of the roll D to be trimmed at the time, and the knives or cuttersC can be adjustedon the shaft B to suit the length 'of the roll D to be trimmed at the time. Y
