specification o f Letters Patent No. 977, dated october 1o, 183e.`

To all whom 'it may concern Beit known that I, HARRISON HOLLAND, of Northampton, in the county of Hampshire and Commonwealth of Massachusetts, machinist, and a native-born citizen of the United States, have invented, made, and

. applied to use a certain machine or improverequired dimensions, to support the ma-V chinery. On the upper surface of the lower girt of the frame Q, are placed at proper distances, any required number of sockets 3, for

. spindles 4, to run in and which areplaced perpendicularly andpassing through a see-` ond girt 5, in` the frame directly above the first mentioned Vand by which they are sustained in their places. These spindles have each a whirl 6, on them between the girts and by which they are connected with a drum 7, hereinafter mentionedf `On these spindles are placed the bobbins 8,5 of raw silk to be spun, doubled, and twisted having above them on the spindles a common, `or flier 9, to twist and carry the silk from the bobbins. Onv the upper side of the upper front girt of the frame, are a number of bent wires 10, corresponding with the Vnumber of the spindles underneath them and over which wires, the silk from the bobbins beneath them is conducted. Directly in the rear of these bent wires is a trough l1, to be iilled with water, or other liquid, having hooks in the bottom of it, through each of which two or more threads from the bobbin 8, are made to meet, and pass in the water. In the rear of, and between each two O-f the front spindles, is a drum 7, placed vertically, and moving horizontally, and which is connected with them by a band or cord 12, passing around the drum and spindles. EachV drum has a dog 13, in its lower head, which drops int-o a corresponding socket, (in a banded pulley 14, when in gear and which connects with the moving power. On the rear bottom girt are placed vertically any required number of dead or standing spin-V dles 15, passing through a second girt above it 16, for support and on which are placed ci fliers 17, with whirls on the bottom 18, and by which they are connected by cords or bands with the vertical drum 7 before mentioned. On these spindles and above the fliers are placed bobbins 19, to receive the silk after it is doubled, and twisted from the front spindles 4. Underneath the lower gudgeon of each `drum 20, Fig. 3, and upon which it rests is a cam 21, affixed to the horizontal rod 22, Fig. 4:, the rod passing through it at right angles and leaving about three fourths of the diameter upon one side. On`

this cam-rod are three upright standards 23,

-Fig 2, one at each end androne a littlein front of the drum 7, the rod running horizontally from front to rear of the machine. The two end standards 23, are loaded at the top end the rod is so balanced that when they are a little inclined upon one side the weight will throw the standards into a hori-` zontal position 24, Fig. 3, by which the cam `on the rod 21, pressing on thebottorn of the gudgeon of the drum 7, throws it up, and

frees the dog 13, in the bottom of the drum from its socket in the pulley 14, below and the drumV stops. parallel with the lines of spindles andv about equidistant from them is a horizontal shaft 25, Fig. 1, supported by uprights in the frame. On this shaft are as many whirls 26, in the form of atruncated cone as thereA are These whirls are grooved crosswise, and

Abovethe drum 7, and

have in the larger end two pins to interlock with a pin'through the shaft `28. At the other end'is a spiralspring, 29, on the shaft,

pressing against the whirl 26, Or the same may be effect-ed by a groove in the whirl to `keep it interlo-cked except when it is thrown lout of gear as is hereinafter described; On

the top gudgeon of each drum is an L 30, having its extreme horizontal line resting on the top of the gudgeon of the drum 7, or running in a groove in the gudgeon, `and is movable on a pin through it at the angle 31, and having the upper end ofthe perpendicular line 32, running in a groove on the whirl `26, on the horizontal shaft 25, above it and when the drum 7, is thrown out of gear by the cam 21, Fig. 3, under its lower gudgeon the same operating by means of the L 30, throws the whirl 26 o-n the horizontal shaft 25, out of gear, and it stops. Directly over each drum 7, and over the horizontal-shaft 25, is a short cylinder 33, Fig. '1, moving on aphorizontal aXis 34, aliXed to an upright 35, and having on the end of the Acylinder next the upright or supporta whirl 36, in the form of a truncated cone and is grooved crosswise, and standing in opposition to the whirl 26 on the horizontal shaft 25, beneath it and with which it is connected by a band or cord the speed of the cylinder being regulated by the form of the whirl. On each thread (passing ott' the first spindles 4,) and between the bent wires Y10, on the top of the machine and the trough, 1l, are hung small rods perpendicularly 37, Fig. 4, having their lower ends connected with a short horizontal lever, 38, which comes nearly in contact with the periphery of the drum 7 behind it. These levers are very nearly balanced on a ulcrum 39, and on the drum a little above them is a pin 40, ott suiicient length'to throw the levers 3S, one side if they come in con tact. On the rear posts of therframe is aflixed a movable upright trame 41, like 'aV sawgate, having arms 42, Figs 2, 3, extending from it to each of the rear spindles 15, to regulate the winding of the silk on the bobbins of these spindles. VA horizontallever 43, or levers supported on a fulcrum'44, eX- tends from this movable frame 41, to the horizontal shaft 25, on which is a heart 45,

Fig. 4, which by its revolutions moves the` levers 43, and with them the movable frame 41, under the whirls on the rear spindles 15, up and down to regulate the winding the silk on t-he bobbins.

them and connected with the Vmoving power. The horizontal shaft 25, is moved by a cogwheel-47, upon it geared into an endless screw 48, on a vertical shaft 49. Each two front spindles 4, are banded upon their corresponding drums 7. And each rear spindle 15, is crossbanded upon the same drum 7. The short cylinders 33, on the .top of the machine are banded upon the corresponding whirls 26, on the horizontal shaft 25. Be?

The drums 7 are moved. by a band 46, around the pulleys 14, belowv vOn the rear, Vtop-gift `are lplaced bent wires ,bottom of the trough, 11, where the threads are doubled, and from thence under, and once around the short cylinder, 33, and over bent wires on the rear top girt of the frame the rearV spindles 15. Should any thread break while the machine is in operation, the small perpendicular rod 37, having upon it,

. would drop,'and the eXtreme end of the lever 38, to which it is attached would be raised and comein'contact with the pin or cog 40, on the periphery of the drum 7, which throws it aside and against the center standard on the cam-rod 22, the balance of which being destroyed, the standards 23, fall into a horizontal position 24, and the cam throws thel drum out of gear, and it stops,y the same operation by raising the drum 7, moves the L 30,by which the whirl 26, in the horizontal shaft 25, is thrown. out of gear, whenall the spindles connectedwith that drum and the corresponding short cylinder 33, will stop.

What I 'claim as my invention and' desireY 50, from thence it is twisted and spun'upon method of changingthe twistv by means of the short cylinders in the manner herein before described.l

In testimony that the foregoing is a full and exact description of my said improvekment and invention I the said HARRISON HOLLAND have hereunto set my hand at -Northampton aforesaid this twenty ninth day of March in the'ye'ar of our Lord oneV thousand eight hundred and thirty seven. Y' HARRISON HOLLAND. [n s] VWitnesses:
