IMPROVEMENT IN SILK-WINDING-MACHINES.

Specification forming part of Letters Patent No. 130,901, dated August 27, 1872.

SPECIFICATION.

To all whom it 'may concern:

Be it known that I, JAMES W. COX, of Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Silk -Winding Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, which form a part of this specification.

My invention has for its object the improvement of silk-winding machines in such amanner that therev is a greater economy in the width of the frame over frames ordinarily used and a greater reduction inthe first cost, while the effectiveness of the machine remains the same. .This is accomplished by using a single shaft instead of the two or three shafts formerly used, said shaft carrying a number of driving-pulleys, the peripheries of which are tangent to the peripheries of the pulleys at- Y tached to the bobbins that are on one side of the machine, and on the other side of the machine the peripheries of the driving-pulleys are tangent to the peripheries of the intermediate pulleys, which, in turn, are tangent to the peripheries of the pulleys attached to the bobbins on that side of the machine.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation. referring to the annexed drawing, whose similar letters of reference indicate corresponding parts, and in which- Figure 1 is a front elevation of a machine such as I propose to use for this purpose. Fig. 2 is an elevation on the side opposite to the side shown in Fig. 1. Fig. 3 is a sectional elevation on the line a: y of Fig. 1; and Fig. 4 is an elevation on an enlarged scale of a portion of Fig. 2, and shows a driving-pulley, intermediate pulley and its support, and bobbin with pulley attached.

The frame of this machine consists of the four end legs A A1 A2 A3, terminating in the uprights B B', all being strongly braced and secured by the cross-beams C, D, D', and E. When the machine is of a sufcient length more legs will be added. About half` way between the cross-beams C and E the uprights branch 0E at right angles and form a rest for the ornamental heads Gr Gr. These support the rods over which the silk passes, (see Fig. 4

3.) At the upper portion of the uprights the shaft p is journaled, carrying the cone-pulley P and the driving-pulleys e e. Attached to the under side of the cross-beam E are the hangers b b. These hangerssupport the bobbins with the pulleys attached, or, as they may be called, the pulley-bobbins e2 e2, in suitable bearings on each side of the cross-beam, and they also support the intermediate pulleys c1 e1 by means of a strap fastened thereto and having an intermediate pulley journaled in the perpendicular sides of each of said straps.

The pulley-bobbins are provided with a shaft;

likewise the intermediate pulleys with which they are journaled in their respective bearings. The drivingpulleys are placed at a convenient distance from each other on the shaft,

and the number used will be one-half of thenumber of pulley-bobbins used, as two pulley-bobbins receive motion from the same driving-pulley. The pulley-bobbins on one side of the cross-beam receive motion direct from the drivin g-pulleys by their peripheries being tangent, and the pulley-bobbins on the other side of the cross-beam receive motion indirect from the driving-pulleys, as the peripheries of both drivin g pulleys and pulley-bobbins are tangent to the peripheries of the intermediate pulleys, so that when the driving-pulleys revolve they cause the pulley-bobbins on both sides of the cross-beam to revolve in the same direction by friction. The pulley bobbins are placed in their respective bearings, those on one side of the cross-beam with the pulley part of each in contact with the intermediate pulley and those on the other side with the pulley part of each in contact with the driving-pulley. Suitable motive power is applied to the cone-pulley and the various pulleys commence to revolve with it. The operators in attendance cause the silk (which is upon reels attached to the parts lettered c c, the reels notbeing'shown, as they only enter indirectly into this invention) to be reeled or wound upon the pulley-bobbins, and as fast as a bobbin is lled it is removed and an empty one substituted from the spool-box F.

These machines can be manufactured at a saving of twenty-Eve to thirty per cent. upon,

the cost of machines that are used at present for the same purpose, While an equally-elicotive machine is produced. These machines are more compact than the ones now in use, as three machines using a single shaft each occu i the same s ace as two machines u sin two or three shafts, While the distance between each singleshafted machine is the same as the distance between double or treble shafted machines.

When the silk is very heavy there is a tendency for the different pulleys to slip. This can be obviated by having` them geared into each other.

Thisinvention applies net only to such silkmachines as are used in the Winding of soft silk, but to cleaning7 and doubling machines, and all other machines of a like c0nstruction.
