WARIPER LEASING-INDICATING MEANS.

Specification of Letters Patent.

Patented May 14., 1918.

Application filed December 10, 1917. Serial No. 206,399.

To aZZ whom it may concern:

Be it known that I, FRED 7001), a citizen of the United States, residing at Taunton, county of Bristol, State of Massachusetts, have invented an Improvement in Warper Leasing-Indicating Means, of which the following description, in connection With the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to a warper or any similar warp or cord handling machine provided with a comb and in which it is desirable to separate the sheet of warp or cords passing through the comb into groups of desired numbers.

The invention more particularly relates to a warper employed in beaming or balling the warp in connection with which a lease is thrown to divide the sheet of warp into groups of desired numbers which groups may be twisted into cords by a subsequent operation.

The object of the invention is to provide in connection with a warper provided with a comb a means for indicating the division of the warp sheet into groups of any desired number and thus enabling the operator to take any desired kind of lease accurately and surely and without delaying the operation of the machine.

The nature and object of the invention will appear more fully from the accompanying description and drawings and W111 be particularly pointed out in the claims.

The drawings illustrate preferred forms of the invention in connection with an ordinary type of beam warper but the invention is particularly applicable to any other type of warper or to any machine where a comb is employed and the leasing of the sheet of warps, cords or strands passing through the comb is to be effected.

In the drawings,

Figure l is a side elevation partially broken away of a familiar type of beam warper showing so much thereof as is necessary to a disclosure of the present invention- Fig. 2 is a front elevation of a portion of the front comb of the warper provided with round dents and showing a preferred form of this invention embodied therein;

Fig. 3 is a plan view of a portion of the front comb of the warper provided with flat dents with the sheet of warps in place and with the lease bands in place after a pin lease of four ends has been thrown;

Fig. 4 is a side elevation of an indicator embodying this invention in place on a flat type of dent;

Fig. 5 is a side elevation of an indicator embodying this invention in place on a round type of dent.

Fig. 6 is a transverse cross section enlarged taken on the line A-A of Fig. 4;

Fig. 7 is a similar cross section taken on the line B-B of Fig. 5. c

As the details of construction of the warper form no part of this invention it will be unnecessary more than to note that the side frame 1' of the warper supports the winding drum 2 which drives by frictional engagement the warp beam 3. At the top'of the machine the sheet of warp 4 passes through a'comb 5 through the drop wires 6 and 7 and thence through the comb 8 and thence to the warp beam 3. a

In the operation of these warping machines whether the warp is laid onto a beam as illustrated, or is balled, it is desirable and necessary to take a lease usually at the end of the operation and this is'done by inserting alternating crossing leasing bands through the sheet of the warp so that the bands divide the sheet of warp into groups of predetermined numbers. When the lease is other than a thread lease or a one and one lease it is necessary for the operative to count the warp off into the groups of desired numbers and thread the lease bands through according to the numbers counted off. This division of the warps is desirable for many purposes and particularly in connection with the manufacture of cords where each group of the warp is in subsequent operations twisted into a cord, such, for example, as is used in the manner of cord vehicle tires.

It takes considerable time for an operative to count the lease ofl in groups say of four each because there are usually a large number of ends in the sheet of warp. F urthermore, if the operative makes a mistake in the count as not infrequently occurs then the lease bands frequently have to be entirely removed and the warping machine and the whole warping operation be stopped while the operative re-counts the lease, thus causing a loss of time and money.

In the present invention indicators are provided which are reinovably attached to the dents of the leasing comb such as the comb 8. These indicators are shown in the preferred form as split sleeves or caps which are slipped over the upper or free ends of the selected dents and which come into clamping engagement therewith by reason of the split construction.

In Figs. i and 6 the indicator 9 made of sheet metal spun or otherwise formed into the shape of a sleeve is split up from the bottom at 10. This sleeve conforms to the shape of the dent end 11 which in Figs. 4c and 6 is of the flat type.

A similar indicator 12 is shown in Figs. 5 and T and differs only in its form which conforms to the end 13 of the round type of dent.

If the operative is required to throw say a pin lease of four ends the operative makes the necessary indications while the warper is running thus losing no time. The operative simply takes a handful of the indicators and places them one by one on every fourth dent slipping them over the free ends of the dent into clamping engagement therewith. The eye will. readily detect whether the count is correct and as the number of ends are known the correctness of the count is also indicated if the last indicator leaves the last group of, ends of the proper number. If the operative makes any mistake a recount may be efiected and the indicators replaced without delaying in any way the operation of the machine.

The leasing is then effected in the usual manner as by passing a long round or oval naeeeee stick with a slot in the end to which the lease band is attached through the shed under and over the groups of warp ends as designated by the indicators.

In the drawings the sheet of warp is shown as divided into groups of four ends but it is obvious that any number of ends may be placed in the groups and indicated by the indicators.

The lease bands 14 and 15 are shown as passed through thesheet of warp in accordance with the indication of the indicators.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a war-per the combination of the leasing comb dents, and a set of warp end group indicators removably attachable to the said dents, whereby when the said indicators are attached to selected dents they indicate the division of the sheet of warps passing through the comb into groups of desired numbers of ends.

2. In a warper the combination of the leasing comb dents, anda set of warp end group indicator each consisting of a split sleeve conforming to the shape of the dent ends and removably attachable to the dents by being slipped over the ends thereof into clamping engagement therewith whereby when the said indicators are attached to selected dents they indicate the division of the sheet of warps passing through the comb into groups of desired numbers of ends.

In testimony whereof I have signed my name to this specification.

FRED WOOD.
