CLOTH-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 441,243, dated November 25,1890.

Application filed May 20, 1890. 7 Serial No. 352,439. (N model.)

To a/ZZ whom it may concern.-

Be it known that I, PATRICK HOWE, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Cloth-Cutting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention is an improvement on that ro class of cloth-cutting machines wherein the cutter-carrying head is mounted on a horizontally-swinging jointed arm made revoluble about a stand or support, as, for instance, in the United States Patent No. 134,7 93, dated 1 5 January 14, 1 877. In the patent referred to the stand or support for the arm rises from the table, and a machine with such form of stand is capable only of cutting single-width goods, and to increase the capacity of this class of cutting-machines to out wider or double-width goods is the chief object of my invention. To accomplish this obj ectI have separated the stand or support from the table and suspended it over the table, substantially above the center thereof, and I have arranged the driving-power and the main and auxiliary arms of the machine in such manner one with relation to the other that the auxiliary arm carrying the cutter-head is free to swing or be moved in a horizontal plane below the main arm, which is mounted on and rotates freely about the stand or support, the cutterhead on the auxiliary arm being free to be swung aside under the main arm, and it may 3 5 travel directly under the stand or support and between it and the table, the cutter being thereby adapted to cut the cloth at any and all points with relation to the length and width of the table, and to cut wider goods than in the other form of machine referred to.

My invention consists in a suspended support or stand, a cutter-carrying head, and two supporting-arms, the arm carrying the cutterhead being movable in a horizontal plane below the arm which rotates about the said stand and also directly under said stand.

Other features of my invention will be hereinafter described, and specified in the claims at the end of this specification.

Figure 1 shows, in front elevation, a cloth 5o cutting machine embodying this invention; Fig. 2, an enlarged vertical section showing the connection between the main and auxiliary arms, and the intermeshing gears for imparting motion to the usual cutter-actuating shaft; Fig. 3, an enlarged vertical section of the stand or support for the main arm; and Fig. 4 a cross-section of the stand or support, taken on the dotted line m 00.

The table A, of any usual or suitable construct-ion, is herein represented as mounted on rollers on a track. The stand or support 6 for the hub tof the main arm is located entirely above the table and preferably above the center thereof. This stand 6 has a flange e, which is represented as connected by screws e to a plate D, held by a cross-bar C, sustained at its ends on uprights or posts B, located at or near each side of the table, free space being left between the posts and the table for the operator to pass. The stand or support c has at its upper end a box-like frame or cap f, which incloses the intermeshing gears 2 3, the one 2 being on the drivin -shaft n and the one 3 on the vertical shaft m, which has its bearings in the stand or support 6. The rotating shaft 0% extends down through the stand or support and has secured at its lower end a belt-pulley m, the said shaft 1% and pulley m constitutin g the driving-power for the usual cutter. The screws (2 permit of vertical adjustment of the stand or support, as well as a very limited tilting movement thereof, for which purpose the hole d in the plate D is made somewhat larger in diameter than the diameter of the sleeve. The hub t of the main arm 25 is sustained by a bearing 29, which is internally screw-threaded to engage the screw-threaded part at the lower end of the stand or support. As the main arm 0 and parts carried by it is very heavy, additional means are provided for holding the bearing 25 in place, consisting, as herein shown, of a set-screw i (see Figs. 3 and 4,)

which enters a groove cut in said stand or support. By loosening the said screw 25 the bearing may be turned to adjust the hubt vertically. The bearing 15 has formed on its top side an annular well, as t, which may r..- ceive and hold oil.

The main arm, as herein shown, comprises a downwardly-extended part 25', which terminates below the belt-pulley m and a rod 0. The rod of the said main arm is screwed into a circular frame or hub 0', which latter supports a shell 0*, containing two intermeshing bevel-gears 0 0 one, as 0 on the rod or shaft 0 having its bearings in said shell 0, while the other, as 0 on arod or. shaft 0 is extended through a pipe 0, connecting said shell and the usual cutter-head, the said pipe constituting the auxiliary arm. The beltpulley 0 is secured to the rod or shaft 0 at its upper end, so as to place it in a line with the belt-pulley m to receive the band 0 The cutter-carrying head 10 is of any usual or suitable construction.

To assist in supporting the parts I have provided the main arm with a brace-rod u, which connects the part with the frame or hub'o, said brace-rod having a turn-buckle u.

The construction of the parts as herein described enables fifty-four inch or doublewidth cloth goods to be laid out perfectly flat on the table, and the cutter-carrying head to be moved over the cloth to cut any part thereof at will, the operator standing at any side of the table.

This invention is not limited to any particular construction of the parts shown, as it is obvious that various devices may be employed to supportthe cutter-carrying head above the table and yet leave the table free and clear and the arms free to be moved to place the cutter at any desired point above the table.

In this invention the rod 0 is connected to the frame 0 in such manner as to lie in a horizontal plane above the auxiliary arm, so that it, with its attached cutter-carrying head, may be swung beneath the main arm and the lower end of the support. This arrangement is important, as it enables all parts of the tableto be reached. By arranging the stand or support over the table, as shown, the said arms may be made quite short and yet reach all parts of the table, thereby insuring lightness and easy working of the parts.

I claim 1. In a cloth-cutting machine, a suspended support or stand, a cutter-carrying head and two supporting-arms, the arm carrying said cutter-head being movable in a horizontal plane below the arm, which rotates about the said stand and also directly under said stand, substantially as described.
