GEORGE H. GILBERT, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE KIE- BOURN KNITTING MACHINE COMPANY, OF NEW BRUNSWICK, NEW JERSEY.

TRANSFERRER FOR KNITTED FABRIC.

LSAA'Y.

To all whom it may concern:

Be it known that I, GEORGE H. GILBERT, a citizen of the United States, residing at Germantown, in the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Transferrers for Knitted Fabric; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention is an improved automatic transferring device for transferring tubular fabrics knit on one machine to the needles of another machine on which the article to be made is completed.

The object of my invention is to produce a machine which will be simple in construction and effective and certain in its operation.

In the drawings accompanying this speci lication I have illustrated one form in which I have contemplated embodying my invention and said invention is disclosed in the following description and claims.

In the said drawings, Figure 1 is a vertical sectional view of my device, parts be ing shown in elevation. Fig. 2 is a top or plan view with parts broken away to show constructions beneath them. Fig. 3 is a side elevation of the bed plate and parts secured thereto, the transfer ring and the ring support being omitted. Fig. 4L is a sectional view of the upper part of my device showing the transfer levers in a diiferent position. Fig. 5 is a side and back view of a transfer lever and a section of the rod on which such levers are fulcrumed. Fig. 6 is a side and back view of the transfer' points. Figs. 7, 8, 9, 10, 11 and 12 are views showing the di'erent positions of the web carrying cylinder and the transfer ring. Fig. 13 is a view in elevation of the web carrying cylinder, and Fig. 14 is a bottom view of the lower' end of said cylinder'. Fig. 15 is a vertical sectional view of a modification, and Fig. 16 is a view in prespective of the fulcrum ring.

In these drawings, A is the table or support to which the device is secured.

B is the bed plate of the machine. This bed plate is provided with a circular open- Speccation of Letters Patent.

Serial No. 415,201.

ing in the center, with a circular or annular upwardly extending wall or flange Z) surrounding the circular opening and another upwardly extending annular flange b. The upper portion of the flange b is rabbeted or cut away on the inside as at b2, and to the reduced portion thus produced is secured the vertical depending wall of the fiat ring C. This ring is composed of two walls joined to form a right angle in cross section. The outer edge of the horizontal portion of this ring is preferably of a complete series of serrations c and from the bottom of each indentation a narrow radial slit or slot extends inward radially. A flat ring C having corresponding serrations, is secured to the top of the wall or flange b with its serrations meshing with the serrations of the ring C, thus covering the space between the two walls or lianges I) b.

The flange or wall I), on its outer side or the side facing the wall b is provided with a shallow curved groove in which a curved rod or fulcrum bar D is secured. In this instance the fulcrum bar is formed from a rod made into a complete ring with the ends fitting closely together. This ring is made of such size as to encircle the flange b when the ring is forced into the curved recess of the flange. In placing it in position the rod or ring is forced downward until it engages the recess. The ring is sufficiently elastic to.

expand to the extent necessary to pass to its seat, then it contracts to firmly engage the recess and hold it in position. Although it is shown in one form as though severed by a direct transverse cut, I prefer to have the ends inclined so as to have one end lap over the other as also shown in Fig. 16. I/Vhile I prefer this construction, this fulcrum may be made integral with the flange b or may be secured thereto in any other way. On this fulcrum bar are fulcrumed the transfer levers d, each of said levers being provided with a curved recess d for engaging said rod. These transfer levers are also preferably provided with a notch cl2 to receive the elastic band or small coiled spring e, which tends at all times to draw the upper ends of the transfer levers inward. These transfer levers d are of the form shown at the right in Fig. 5, the lower part being-of a single thickness of metal. The lower part is to partly surroundand cover the ends of the points of the transfer ringso that there will be no obstruction to the stitches when moving them from the levers to the'points.

On the inside of the wall or flange Z9 and resting on the bed plate of the machine is a flat ring E secured in position in any prefered manner. The inner edge ofthis ring is provided with narrow slits or guide ways for the lower ends of the transfer levers d, the lower ends of such levers, being made of such a width that the fullest extent of move- 4'ment that can be given them will not cause themto leave these guide ways'.

Within the space between the two walls or flanges b Z9 is a ring F having Vits outer side fitting closely, but movably against the inner side of the wall or flange Z2. To this ring are secured three pins f proj ect-ing outwardly through vertical slots in the wall or'flange Z9. Avertically disposed ring G is movably fitted to the outside of the wall 'or flange b and is provided with three inclined slots g through which the pins also pass; To this ring Gr is secured the arm g by which the ring G' can be moved to right or left to raise or lower the ring F.

The ring F, when depressed, comes in contact with the lower outwardly inclined ends of the transfer levers forcing them inwardly and causing them to 'turn on the fulcrum rod and throw their upper ends outwardly against the tension of the elastic band e. Vhen the ring F is raised this elastic band draws the upper ends of said levers inwardly.

The ring Gr is held from vert-ical movement by 'any preferred means, In vthis instance, it is held in position by resting upon the bed plate of the machine and by a downwardlyY extending flange of the ring C.

The arm g" is preferably slightly elastic and is' provided on its under side'with a knife edge g2 which engages notches Zt in a retainer bar H, secured to the bed vplate or table. The notches being located so as to be engaged by the knife edge when the ring F is at the upper or lower limit of its movement. By this means the ring F when moved to one position is held from accidental displacement.

To the bed plate of the machine are securedtwo standards I, I, and to the upper ends of these standardsv are secured a flat ring J, having a central opening larger than, but concentric with, the opening in the bed plate. The inner edge of this ring is rabbeted or recessed to receive the transfer ring K, and is provided with devices y' for holding the transfer ring in place when it has been placed in position. The transfer ring K is provided with the usual transfer points c conforming to the size and gage of the knitting machine to which the knitted web is to be transferred. The ring J at one point of the recessed or babbeted portion is provided with a projection y" extending into the recess and the transfer ring is provided with a notch or recess to engage the same to secure the proper alinement of the points of the transfer ring with the transfer levers.

To the underside of the bed plate B, a hollow cylinder L is secured in any preferred manner. In this instance it is secured by an outwardly extending fiange secured to the underside of the bed plate. The lower end of this cylinder is provided with the elongated boss Z through which passes a shaft L2 is provided with a crank or hand vertical direction, and the opening is enlarged on one side toreceive the teeth of a rack Z2 secured to or formed on the shaft. A horizontal shaft L2 is provided with a spur gear Z3 meshing with the rack Z2. The shaft L2 is provided with a crank or hand `wheel (not shown) by which the shaft can be turned in either direction to raise or lower the shaft L.

M is a cylinder adapted to .be placed on the upper end of the shaft L', and at its upper end is a brush portion m. The lower part of this brush portion is of the saine size exteriorly as the cylinder but near the top the diameter is increased to form the expanded portion m (see Figs. l and 13). To the bottom of the cylinder M is secured thc plate m2 provided with the curved key hole slot m3.

Upon the shaft L is secured the collar or disk N which is provided with the headed pin or screw a. Zhen it is desired to apply the cylinder M to the shaft L the cylinder is dropped down upon the shaft until it rests upon the collar N. The enlarged po-rt-ion of the key hole slot is passed over the head of the pin or screw n and the cylinder` turned to bring the pin to the opposite end of the slot when the cylinder will be held upon the shaft against displacement from a rising or falling movement.

The cylinder M has its main portion of a size to fit within the tubular web to be transferred without materially stretching the same, but it will be seen that the expanded part m of the brush portion will slightly stretch or expand the web when drawn over it.

In operating the device, a web to be transferred is placed upon the cylinder with the 'LIU upper end of the same in about the position shown in Figs. 1, 8, 9 and 10. In doing this, care is to be taken to see that the web at the point that the upper ends of the transfer levers will engage it when in the position shown in Fig. 9, shall be so drawn or expanded that the spaces between the wales shall be substantially of the same width as the wales themselves. The ring F will then be depressed to throw the transfer levers into the position shown in Figs. 4l and 7. The cylinder will then be moved to the position shown in Fig. 8, and the transfer levers thrown into the position shown in Fig. 9 against the expanded portion of the brush part of the cylinder. The cylinder is then raised slowly until the upper ends of the transfer' levers CZ rest upon the web at the point where the wales and the spaces between them are of equal width, see Fig. 10. As the transfer levers are drawn toward the center of the machine by elastic or spring pressure and as the number of levers are equal to the number of wales and the spaces between them taken together, on this movement of the cylinder, everyalternate lever will naturally fall into the spaces between the wales, leaving the remaining levers with their points upon the tops of the intervening wales. The cylinder M is now depressed causing the upper ends of the transfer levers to pass through the loops opposed to the ends of the same, as sho-wn in Fig. 11. The brush holds the web from being forced inwardly by the points of the levers in passing through the fabric to take the loops. Were the web carrier of continuous solid material the levers would not pass far enough through the web to securely engage the loops, and dropped stitches would result. The brush also protects the points of the levers as it provides a space back of the web into which the points may pass without engaging the solid portion of the web carrier, thus preventing the dulling of the points and the buckling or bending of the levers. As the transfer' levers are now in a position inclining outwardly, the web as it passes over the upper ends of these levers is further stretched at this point causing the upper end of the web to bend or curl over outwardly upon the outer side of the levers, as is also shown in the same figure. The transfer ring being now in position the ring F is depressed throwing the transfer levers outwardly until the upper end of each lever engages its corresponding point on the transfer ring. In this movement the grooved back of the transfer lever passes over and covers the extreme end of the transfer points of the transfer ring.

The cylinder is now raised carrying the web with it, and drawing the loops of the web upward onto the fingers or points of by a single revolution of the cam cylinder, as

sometimes done heretofore.

The parts may be placed in the position shown in Fig. l before inserting the cylinder and web and the operation otherwise varied.

There may be a considerable number of cylinders M for each machine and also considerable numbers of transfer rings K. A number of the cylinders may be prepared with web so that as soon as one is removed from the machine, another can be applied and so too there may be a number of the transfer rings, some of which may be filled and held in readiness for the knitting machine.

In Fig. 15 I have shown a modification. In this figure the collar N is shown provided with the upwardly extending tube N within which the lower end of the web carrier is placed. Vhen the loops have been forced upward onto the points of the transfer ring, the further upward movement of the web carrier turns the web the other side out at the same time effectually drawing the loops to their proper position on the transfer points.
