1 Claim.

The present invention relates to fulling mills, and aims to increase the efficiency and quality of work of the mill, and to simplify the manipulation thereofr V The invention provides anovel and improved form of guide or stretcher capableof exerting 1 any desired degree of retarding force on the cloth, to bring it to the desired length-dimension, while additionally bolth aiding in the widthwise condensing and'fulling action and limiting the number of strings composing a single bundle, to prevent overloading'of the milland defective work as indicated hereinbefore.

Other features of the invention are as will be made plain hereinafter.

An illustrative embodiment of the invention is set forth in the accompanying drawings, in which,

Fig. 1 is an elevation in section on a vertical longitudinal plane of the improved fulling mill.

Fig. 2is a ,plan View of the front portion of the fulling mill of Fig. 1, with the top of the machine removed and omitting the driving mechanism.

Fig. 3 isan elevation looking into the opened front end of the mill, showing the improved stretchers;

In the housing I are suitable fixedbearings for the bottom-roll shaft 3 and floating bearings for spring-loaded top-roll shaft 5. Preferredly a separate pair of short opposing top and bottom rolls 1, 9, is provided for each guide-eye or stretcher II and consequently for each group or bundle of strings, the illustrated mill being designed to handle four bundles. The length of each pair of short rolls is made adequate to deal properly with all the cloth capable of being put through a single stretcher without surplus tempting the attendant into overloading; Each'opposing pair of rolls has its individual crimping box l3 with sides extending forward of the rolls into proximity to the stretcher, and with swinging tongue [5 depressedby weight W through conventional linkage. i

Cross-girths l l fixed on the interior of the side-walls l9 at equal distances above and below the level of the top'of bottom rolls S-support uprights 2 l equipped at midlength with bearings 23 in which are held journals 25 integral with the guides or stretchers H. These guides are preferredly formed of hollow noncorrosive metal, outlining an aperture having oppositely-facing convergent-sided extremities, being of general diamond shape with the angles of the diamond rounded, this aperture having materially greater 2'! is fixed, in the forked end of which is mounted a swivel-nut which is in screw-threaded engagement with the shank of adjusting screw 29 equipped with hand-wheel 3| outside the housing directly above the doors giving access into the front of the machine. A collar 33 is applied to each screw just inside the housing.

By rotating the screw 29 through hand-wheel 3!, each guide or stretcher H can be given any desired degree of obliquity with relation to the line of travel of the bundle of cloth passing through such eye in its course from whip-roll 35 to the nip of the opposing rolls 1, 9. The

more oblique the angle between the plane of the guide or stretcher and such line oftravel, the more tendency there is for the bundle of cloth to wedge into the extremities of the diamond shaped aperture, as a result of the cloths resistance to being forced into a devious path. Being held into a compact bundle by engagement with the oppositely-facing V shaped ends of the diamond, while simultaneously confined by the sides of the diamondadjacent the journals, an extremely powerful frictional grip upon the bundle of strings of cloth passing through the eye is accomplished without the straining or fracture of the yarns at the outside of the bends formed by prior types of stretchers which force the cloth into a crooked path through the use of transverse bars. The shaping of the improved'guide or stretcher permits generous extension of the depthof its section in the direction of travel of the cloth, whereby its bearing surface on the cloth is greatly increased, with lessened damage to the fabric.

. The size of the diamond shaped opening in the guides or stretchers I I through which the bundle of strings must pass to reach the rolls is such as to limit the volume of cloth definitely to the maximum amount which can be properly worked and fulled between a single pair of the correspondingly limited opposed rolls 1, 9, or at any one located in the length of full-width rolls;

While we have illustrated and described one form in which the invention may be embodied, we are aware that many modifications may be made therein by any person skilled in the art, without departing from the scope of the invention as expressed in the claim. Therefore, we

do not wish to be limited to the particular form What we do claim is:

In a cloth fulling mill, in combination, opposed rolls propelling the cloth, a guide through which the cloth passes having oppositely-facing convergent-sided extremities, transversely extending journals intermediate such extremities, a lever fixed to one of such journals, and manually-operable means in connection with such lever adjustably determining the angular relation of the guide with respect to the line of travel of the cloth passing therethrough.
