MACHINE FOR APPLYING PERIPHERAL BANDS.
Specification of Letters Patent.
Patented July 9, i917.
Application filed August 29, 1913. Serial No. 787,391.
To all whom it may concern.
Be it known that I, IIENRY C. HERB, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Applying Peripheral Bands, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates to machines for-applying peripheral bands and is more particularly designed for use in the manufacture It is the object of the invention to provide means for first tightly drawing the band about the body to be bound thereby, and then to secure the overlapping ends of the band to each other so as to retain them in clamping position. To this end the invention consists in the peculiar construction and arrangement of the mechanism as hereinafter set forth.
In the drawings:
Figure 1 is a plan view of the machine;
Fig. 2 is a cross section on line 22 Fig. 1;
Fig. 3 is a side elevation of the machine;
Fig. L is a longitudinal section on line M Fig. 1; and
Fig. 5 is a perspective view showing the product of the machine.
The specific article which is operated. upon by my machine is a barrel head formed of a plurality of board sections A B C, which together form a complete circle and which are bound by a peripheral band B. To secure the head sections to this band said sections are provided with V-shaped peripheral groove or eroze therein, while the band or hoop is fashioned with a corresponding V- shaped projection for fitting said eroze and holding the sections from displacement. The bands D are preferably formed by rolling, in order to be of the proper cross section and of a circular form approximating the size of the head, with overlapping end portions. The metal is sufficiently resilient to permit of expansion to engage the head section therewith, after which the parts are in position for operation of the machine.
The machine comprises a bed or table E supported upon suitable standards E, and provided on its top with a circular clamp F for receiving the head with the band loosely in conformity to the general cross section of said hoop or band. At one point, preferably midway of its length, the clamp F is pivotally attached to the table by the pin G, while the opposite ends are provided with pivotal connections H to toggle links I and I mounted upon the table. Secured to the pivots H are rollers H engaging guide slots H in the table, the arrangement being such that when the toggle links are straightened the ends of the clamping band F will be forced toward each other, contracting the circle and tightening the band D. Suflicicnt space is left between the ends of the band F for the overlapping ends of the band D, and in this space is located a clenching or bandsecuring mechanism which will be hereinafter described.
To operate the clamp F, as well as the clenching mechanism, a suitable mechanism is mounted upon the table, preferably on the underside thereof. This, as shown, comprises a drive pulley J directly connected with a pinion J, which latter meshes with a gear wheel K sleeved upon a shaft K having thereon a pair of pinions K and K respectively meshing with gear wheels L and L upon a shaft L and upon opposite sides of the central plane of the machine.
These gear wheels L and L are provided with crank pins engaging rods or links M and M, which at their opposite ends are pivotally attached to rock levers N and N fulcrumed at N beneath the table E. The upper ends of these rock levers extend into slots 0 and O in the table and are con nected by pivotal links 0 and O with sliding blocks P and P engaging slide-ways P on the top of the table. These blocks P and P are in turn pivotally connected with links Q and Q which are centrally pivotally connected to the toggle links I and I, which, as before described, are attached to the ends of the clamping band F. The opposite ends of the toggle links I and I are pivoted to adjustable bearings upon the table, formed by blocks I slidably secured in bearings I and adjustable therein by set-screws I the may be shifted and the clamp F correspondingly adjusted.
The train of mechanism above described is adapted to cause the tightening and loosening of the clamp F whenever movement is imparted to the shaft K from the gear wheel K. The latter is constantly driven by the pulley J and pinion J, but is only intermittently coupled to the shaft K through the operation of a trip clutch K This clutch, which is not shown in detail, is of such a character that when tripped it will couple the wheel K to the shaft K, maintaining the coupling during one complete revolution of the gear wheels L and L, after which the clutch is again released. This revolution of said gear wheels will cause the crank-s and connecting rods M and M to operate the levers LT and N, links O and O sliding blocks P and P and links Q and Q, which will straighten the toggle links I and I and contract the band I about the head and hoop D. The clamping is effected by one-half revolution of the gear wheels L and L, and during the remaining half revolution the parts are moved in the opposite direction, releasing the clamp and expanding it to its normal position.
The clenching mechanism for securing the overlapping ends of the hoop is arranged to operate thereon when the clamp F is contracted and before the releasing of the same. This mechanism, as shown, comprises a lipping punch and die adapted to strike portions of one of the overlapping sections through apertures in the other section and to clench the same, thereby securing said sections from relative movement. In detail, R and R are slidable blocks arranged in the longitudinal central plane of the machine re spectively outside and inside the clamp F 1 and opposite the space between the ends of said clamp. These blocks R and R engaging slideways R on the table, are provided on their undersides with rack sections R which are in mesh with segmental rack sections S upon rock levers S" and S fulerumed upon the frame. The lower ends of these rock levers are provided with rollers S and S which engage a cam wheel S upon the shaft L which cam wheel is so fashioned that different peripheral portions thereof engage with the respective rollers S and S S is a spring for holding the rollers S and S in contactwith the .cam S. The sliding blocks R and R have adjustably secured thereto the punch and clenching members T and T which cooperate with a stationary die member U secured to the table E. Thus during the rotation of the shaft L in the operation of the clamp ing mechanism as previously described, the cam S will actuate the membersT and T. The timing of the operation is such that the punching member T is actuated atthe c0m pletion of the contracting movement of the clamp F, and the punch is so fashioned that it will strike out lips from the two overlapping sections of the hoop D, bending these lips to extend transversely and in a position to be clenched by the subsequent operation of the member R. The whole operation takes place before the clamp F has released its pressure, and thus the band D is prevented from expanding or releasing its pressure upon the head sections.
The complete operation of the machine is as follows: The head sections and hoops D being first assembled by hand, the operator successively places the assembled heads within the clamping band F, which in its normal position is expanded suthciently to rcceive the loose band D. The clutch K is then tripped, preferably by a pedal V connected by the rod V, bell crank lever V rod V and other linkage with the trip rod Upon this rod is a collar \V carrying a roll V which is adapted to engage with a recess in the slide P when the latter is in its normal position, while a spring 7 sleeved upon the rod it, yield-ably holds said roll in engagement with said recess. Thus when the pedal V is depressed the rod W is moved against the tension of the spring W, withdrawing the roll Vi from the recess and alsoreleasing the clutchengaging mechanism which couples the gear wheel K to the shatt K. \Vhen the mechanism is tripped by the pedal V as just described, motion will be imparted from the shaft K and pinions K and K thereon to. the crank gears L and L; and through the links M and M, levers N and N, links 0 and 0*, slides P and P and links Q- and Q, will gradually straighten the toggle links I and I. This will progressively contract the circle of the clamp F, thereby similarly contracting-the band D and causing its overlapping ends, which are in the space between the ends of the clamp F, to slide over each other until the band is in tight contact with the periphery of the head sections. Allthis occurs during the half revolution of gear wheels L and L, and by adjusting the set screws I any desired degree of clamping may be effected. Then the clamp is fully contracted the cam S operates first to cause the punch T 'to perforate the overlapping section of the band D, striking out preferably a pair of tongues or ears therefrom and then through the operation of the clencher T bending over these cars or tongues into a locking engagement. ment of the mechanism will expand the clamp F by the opposite movement of the cranks and intermediate mechanism connected with the toggle linksv I and I, and just at the completion of this reverse operation the recess Vi in the sliding block P will register with the roll W whereupon the spring W will force the trip rod V into position to disengage the clutch K and stop further movement. This completes the cycle and the operator can then remove the completed work and place another head in the clamp F, after which the operation is repeated.
The rollers H engaging the guide slots H serve to cause the contraction of the clamp F by the toggles I and I without undue radial pressure at the pivotal points H. These pivotal points H are also placed a short distance from the ends of the clamp so as to provide projecting nose portions H which are free to turn upon the pivot in conformity to the curvature of the band.
