BARNETT HANSELL, JOHN MCGANN, AND SAMUEL MCUAMBRIDGE, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN APPARATUS FOR CUTTING (DLOTIEI.V
Specification forming part of Letters Patent No. 39,@62, dated September 8, 1863.
To all whom it may concern:
Be it known that we,A BARNnT'r HANsELL, JOHN McGANN, and SAMUEL MGGAMBRIDGE, of the city and county of Philadelphia, and
State of Pennsylvania, have invented a new and useful Improvement in Machines for Cutting Cloth for Tents and other Purposes; and We do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had tothe annexed drawings, making a part of this speeitication, in Which- Figure l is a perspective view of the machine. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a perspective view of the slotted cutter-bar J. Fig. 4 is a perspective view of the slotted extensionbar J. Fig. 5is a perspective view of one ofthe slitting knives Q, in combination with its stock It. Fig. (i is a persp. ctive view ot' the supporting-har T.
Like letters in all the iigures represent the same parts of the machine.
. The nature ot' our invention will be understood by the following description:
WVe construct a standing frame, A, to receive the several parts of the machine. B is a cylinder, over which the cloth is wound to be cut into the required length. lt has a central shaft, G, Whose journals D D turn iu appropriate bearings in the uprights E E ofthe standing frame A. F is an endless apron, which encircles the said cylinder B and the roller G, whose journals turn in the uprights of the frame H, the said frame beingeonne'cted with the frame A at its lower end by means of the mortises c tand pins b b. The upper end of the frame is adjustable for the purpose of giving proper tightness to the apron Fby means ofthe braces I Lwhose lower ends turn on the pins o c and in the mortises d d ot' the frame A', the upper end of the braces loeiug adjustable bymeans of the notches f ff fff ofthe frame H. rlhe 'frame A is made separate from the frame A, so that it may be bolted fast to the door of the buildingl at any requisite distance from the latter fra-me to bring the roller Gr the proper distance from the cylinder B to suit the length of the apron F, which corresponds to the length or lengths of one or more pieces into which the cloth is to be cut. There is a bar, J, to which theends of the apron F are confined, one end being passed through the longitudinal slot g and the other through the slot g and sewed fast to the bar. The pricks It 7L IL h h (see Fig. 3) serve for the purpose of attaching the front end of the cloth which is to be cut to the bar J. The inner edge of the slot g'also serves as a guide for a knife which is drawn through said slot -to out the cloth into lengths when a sufficient quantity has been wound around the apron for that purpose. There may be tW'o or more otl the slotted cutterbars J connected with the apron F, which may be either at equal or unequal distances, so that the cloth may be cut either ot' equal or unequal lengths, as may be desired. There are ways K K which serve as supports for the bar J, the ends ot' which rest upon them While the cloth is being cut into lengths. The legs have slotsjjjj through which the screws 7c 7c lc k pass and confine the legs to the frame A, The object of the slots is to vary the ways K K in their elevation and angle to suit. any variation which may be made at any time in the length of the apron F. `The said apron is only used When the circumference of the cylinder B cannot be conveniently made to suit the lengths into which the cloth is to be cut,an'd we seldom Iind occasion to use it except Awhen we cut the cloth into very long lengths. At other times the apron is detached from the machine, and the cloth is wound simply around the cylinder B.
For the purpose of varying the circumference or" the cylinder B, in order to vary the length ot' the pieces into which the cloth is to be cut, there is an extension-bar, J', or, if necessary, there may be several arranged around the cylinder.` The bar J has legs m m, (see Figs. 2 and 4,) which are movable in the grooves n n inthe heads of the said cylinder. (See Fig. 2.) The said legs are confined by means of the screws o o, which pass through the slots p p, which lead into the grooves n a. The extension of the bar J is represented by red lines in Fig..2. There is a longitudinalslot, g, in the extension-bar J, for the same purpose as a` guide for the knife as the slot g in the har J.'
L L are tensionbars for the cloth M as it is drawn either on the cylinder B or theapron F. They are permanently fastened to the uprights'C C. of the frame A. There are adjustable guides N N for the cloth, which have mortises or slots q q (see Fig. 2) equal in length to the distance across the bars L L. They are secured on the said bars by means of the setscrews r r.
P is a tension-roller for the cloth, auxiliary to the bars L L. Contiguous to and in front of the said roller we place any number of knives, Q Q, for cutting thel cloth into required widths. These knives have stocks B B, (see Fig. 5,) which fit in the longitudinal groove s of the bar S, 'which is permanently secured to the uprights C Cof the frame A. The knives Q Q are adjustable by means of the setscrews tt, which pass through the longitudinal slot u of the bars S.
T is a support-bar for the cloth M to steady the same as it is acted upon by the slittingknives Q Q. For the purpose of lowering the said bar when a piece of cloth is to be attached to the cylinder B, there is a hole, c, in its rear end, (see Fig. 6,) which tits on a piu or screw in the upright C at the rear side of the machine. When the bar is in its elevated and acting position,its front end is secured by means of the spring w on the front upright, C. (See Fig. 1.) Sometimes some of the strips of cloth which are wound around the cylinder B or the apron F are not to be cut into the same lengths as the other strips, and for the purpose of taking them out-of the way, as their attached ends come under the cylinder B, after they have passed around the same, we give the ends a turn or two on the roller U, which is made to wind said strips up by means of the band V, connecting said roller with the cylinder B, as seen in Fig.` 1.
The operation is as follows: The front end ofthe cloth being passed around the tensionbars L L and roller l, and caught on the p ricks h h h hh ot' the bar J, the c) linder B is turned in the direction of the arrow, which Winds the cloth a round the apron F,the. knives Q Q, in the mean time, slitting it into the required widths; and any one of the strips that is not to be. cut of the same length or lengthsas the others has its front end disengaged from the bar J, and is wound a turn or two on the roller U, to secure it to the same, the machine having been stopped for that purpose. Then the machine is again started, and when a sufficient quantity is wound on the apron to be cut, the machineis again stopped, with the bar J resting on the ways K K, and a knifeis drawn th rough the slotg ot'said bar, and against the inner edge of the slot, cutting all the strips across that have to be cut into the same lengths, and then the operation of winding and cutting the cloth is again proceeded with, as above described. The cloth that has been wound on the roller U may at any time be taken off of the same and laid aside to be cut alone, or may be transferred to the apron F, or cylinder B, to be cut into suitable lengths with other cloth, as the opera-tor may deem best. In the 'former case we take the roller out of its place and slip the cloth from it in a careful manner, so that it may again be placed on it when occasion may require. For the purpose of detachin g the roller, the bearing for one of the journals (see Fig. 2) is open and has a shifting support-bar, in front to hold it in place, the said bar being held by the screw y at its bottom end, on which it turns, and catching at its upper end between the bent rod z and the upright C', in which one end of said rod is fastened. We, however, usually make the bearings for thejournals of the roller in the opposite side of the uprights C C', which supercedes the necessity of naviug anything to cover thejournal. In case the cloth is to be cut into short lengths, the use of the apron F is dispensed with and the cylinder B is merely used for winding the cloth. When we wish to cut the ends ot' the pieces of cloth of angular or curved form, or any other form otherwise than square, instead of making the cutter-slot in the extension-bar J We make it in the periphery of the cylinder B, which has to be ofunbroken surface, at least where the slot or slots are formed.
Having thus fully described the construction and operation of the machine for cutting cloth for tents and other purposes, What we claim therein as new, and desire to secure by Letters Patent, is
l. The construction ofthe cylinder B, with one or more cutter-slots g, substantially as described, for the purpose of cutting the cloth into denite and suitable lengths and forms, as above set forth.
2. Combining and arranging the extension bar or bars J with the cylinder B, ior the purpose of varying the circumference of the latter, substantially as described, and for the purpose set forth.
3. Constructing the. apron F with the slotted cutter bar J, when combined and arranged with the cylinder B, substantially in the ina-nner and for the purpose above set forth.
4. The combination ofthe knives Q Q with the cylinder B, when arranged and operating substantially as described.
5. The combination and arrangement of the reciprocating roller U with the cylinderB, substantially as and for the purpose above set lorth.
6. The arrangement ofthe support-bar T in relation to the knives Q Q and cloth M, substantially as described.
In testimony that theabove is our invention we have hereunto set our hands and affixed our seals this 17th day of June, 1863.
