HOOP-CUTTING MACHINE.
SPECIFICATION forming partici Letters Patent No. 392,651, dated November 13 1888.
Application filed May Q2, 1888. Serial No. 274,653. (No model.)
.To all whom it may concern:
Be it known that l, ALEXANDER F. WARD,
a citizen of the United States, residing at Detroit, in the county of Vayne and State of g Michigan, have invented certain new and useful Improvements in Hoop-Cutting Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in hoop-cutting machines of that class wherein a cutting-knife is employed to cnt the hoops from the edge of a plank with the usual bevel given to hoops; 15 and it consists in the construction, arrangement, and combination of parts hereinafter more particularly described, and then definitely pointed ont in t-he claims.
In the drawings which accompany this 2o specication, Figure l is a perspective view of my improved machine. Fig. 2 is a vertical central erosssection through the same. Fig. 3 is a side elevation thereof. Fig. 4 is a plan of the frame and bed with some of the operating parts removed. Fig. 5 is a diagram showing two alternate positions of the knife in cutting off the hoops, and Fig. 6 is a similar diagram on a larger scale.
Ais the frame which supports the operating 3o parts of the machine. Bis a bed-plate support ed thereon, andCareaseries of upwardly-projecting flanges, the upper edges, D, of which form a table,upon which the plank from which the hoops are cut is supported and fed by the operator under the reciprocating knife E, which cuts off the edge of the plank to form bevel-hoops. Below the cutting-edge of the knife a cutting-bloclr,F, is secured in the bed, preferably adj ustably and removably,such as by means of the clamping-plates G, which are secured by the bolts a to the fraaie of the machine. The cutting-block F is preferably made in short lengths of wood, so as to be more easily adjusted in relation to the cutting-edge of the knife.
The knife is adjustably secured in the usual manner to the knife-head H, which extends longitudinally the whole length of the table, and is provided at each end with the arms I, by means of which the knife-head is pivotally secured at Z) to the upper end of the shift ing bartJ and to one end of the link K, the other end of which is pivotally secured at c to the frame of the machine. The lower end of the shifting bar J is pivotally secured to a wrist, d, on the rock-arm L. This rock-arm is secured upon the rock-shaft L', which is journaled in bearings longitudinally of the frame, and another wrist-pin, e, on the rockarm L engages into a cam-groove, f, formed 6o on the upper end of the vibrating lever M. This vibrating lever has a JnXed fulcrum at g, and is pivotally connected at its lower end at 7L with the free end ofthe eccentric-rod N. This eccentric-rod has its actuating-eccentric Nse- 6 5 cured upon a shaft, O, to which is secured the gear-wheel P. This gear-wheel meshes with the gear-pinion Q upon the main drive-shaft E ofthe machine, and by means of the eccentricS, secured upon this d rive-shaft, and the ec- 7o centric-rod S', actuated thereby and pivotally connected with its free end to the wrist t' on the side ofthe knife-head,a reciprocating motion is communicated to the knife, which motion is on the arc of a circle having pivots b for the fulcrum. The relative diameters ofthe drive-pinion Qand the gear-wheell? being as one to two, theknife will make two strokes to one revolution ofthe eccentric N', while theleveir M, actuated by said eccentric, will make two vibra- 8o tions at the same time, thus carrying the wristpin e of the rock-arm L from one end of the cam-groove to the other. This cam-groove is so formed as to rock the rock-arm L and thereby shift the pivot b by means of the connection J from one of the two positions, as shown in Figs. 5 and 6, where one position is shown in full lines and the other is shown in dotted lines. This shifting of the pivots of the knifehead causes an alternate tilting of the knife, 9o so that while one hoop is cut with a bevel upward, the next hoop will be cut with the bevel downward, and so on lalternately.
The plank is fed by the operator against the stops T, which reciprocate in vertical bearings at the rear side of the cutti11g-block, and these stops T are secured to the common head U, which extends horizontally, and is connected at its rear end, by means of the links V, to the knife-head,rso that the reciprocating motion roo of the knife-head raises and lowers the stops in a proper manner to enable the operator to adjust the plank against the stops and at the same time to throw them out of the way as soon as the hoop is ont, to permit of having said hoop removed by means of the oscillating arms IV, which are secu red upon the shaft W', which is provided upon its ends with the rockarm or rock-arms j ,which bylineans of the connecting-link 7c are connected to the rock-arm Z upon the shaft L, all so arranged that by means of this connection a single vibration is given to the arms XV to remove the hoop from the rear end of the bed as soon as it is cut.
It will be seen from Fig. 6 that the motion of the knife being in the are of'a circle, one side of the hoop will be cnt slightly concave, and this I consider imparts an improved quality to the hoop to better hold it upon the bar rel, provided it is placed with its concave side toward the barrel, and I believe these hoops to be a new and improved article of mannfacture, which have never heretofore been made with any hoopsmachine of this class nor of any other kind.
As it is often required to alter the thickness of the hoops, I provide all the parts, where necessary to effect the object, with the necessary adjustment, which may be of any desired construction.
' W'hat I claim as my invention is- 1. The combination, with the frame and bed of a hoop-cutting machine, of a knife and its head and means, as the eccentrics Nand S and intermediate connections, for giving said knife a eurvilineal cutting motion in different paths alternately, substantially as described.
2. The combination, with the frame andbed of a hoop-cutting machine, of a knife attached to a head mounted on a movable pivot and means, as the eccentrics N and S, for moving said pivot in opposite directions and the knife in a curvilinear direction in different paths alternately, substantially as described.
3. The combination, with the frame and stationary bed of a hoop-cutting machine, of theV knife-head constructed and arranged to carry.
the knife in the are of a circle in different paths alternately, the arms I moving in the same plane at each stroke, and pivot on which said arms Work, reciprocating in a straight line to and from the paths of the knife,
the wrists?) on arms I, the main drive-shaft R, the eccentrics S on said shaft, and the eccentric-rods S', secured to the wrists z', and all ar ranged to operate substantially as described.
4. The combination, with the frame, knife, and bed of a hoop-cutting machine, of a reciprocating head, H, arms I, carrying said head andV moving always in the same plane and pivoted on a movable fulcrum, b, and means, as the eccentrics N and S and intermediate connections, 'for changing the position of the fulcruni, and thus giving the knife a curvilinear reciprocating motion in different paths alternately, substantially as described.
5. The combination, in a hoop-cutting machine, of the following elements: a stationary table, a cutting-knife mounted to reciprocate in the are of a circle, a knife-head pivotally securedand carryingsaidknife,a cutting-block ,secured in the rear end of the table, two or more vertically-reciprocating stops at the rear end of the table, two or more vibrating arms to remove the cut hoops from the table, mechanism for reciprocatingly actuating the knife, and mechanism for shifting the pivots of the knife-head alternately into one of two positions, substantially as described.
6. The combination, in a hoop-cutting machine,'of the stationary table, the cutting-knife reciprocating in the arc of a circle, the knifehead pivotally secured and carrying the cutting-knife, the main drive-shaft R, the coun ter-shaft 0, the eccentric N', the lever M, connected to the eccentric and provided with the cam-groovef, the rock-arm L on the rockshaft L', and the links J K, the parts being arranged and constructed to operate substantially as described.
