T aZZ whom it may concern:

Be it known that I, J OHN WILLIAM RYAN, a subject of the King of Great Britain, and resident of Gledhow Mount, Harehills Lane,

' Leeds, in the county of York, England, have invented a certain new and useful Improvement in Fallers or Gill Bars for Treating Textile Substances, of which the following description, having reference to the accom- W panying sheet of drawings, is a specification.

In the type of machine to which this invention relates the fallers or bars which carry the pins for combing or treating the M fibrous substances have to be raised from being operated by their pairs of screws in one plane so that they may be operated in a contrary direction by screws mounted in a higher plane. In these operations each 959 faller is raised by cam action from engagement with its lower operating screws into engagement with its upper operating screws and on being thus raised when the upper screws are engaged with, a slight advancing movement is given to each faller prior to the time that it reaches its highest position, thus provision has to be made to permit this slightly advancing movement prior to the faller reaching the upper surface of its guiding bars as is well understood. Heretofore this provision has been made by the outer guiding ends of the horizontal slides or guides for said fallers being of an inclined character thus the lower edges of these inclined guiding surfaces have had to be limited in width or dimensions so that the whole of the abrading actions of all the fallers moving over said surfaces was to be withstood by the comparatively small guiding surfaces of said bars, hence considerable deterioration and wear have been experienced in connection with these guiding surfaces. To obviate these disadvantages and defects by constructing said end guiding surfaces on the bars of the formation hereinafter described and by the formation of the fallers as is hereinafter explained, is the object of my present invention. This object I attain by following the method of construction or formation hereinafter described and illustrated by the accompanyin sheet of drawings wherein i ig. 1 is a sectional side elevation of the upper and lower screws of a gill box or gill frame on one side of said frame, a pair of screws ofthe samecharacter, are mounted on the opposite side of the frame in manner well known. Only one guiding bar and the fallers in connection therewith are shown in this figure. w l l v i 1 ,Fig. 2 is a view of the parts shown by Flg. 1 looking in the direction from left to right of said figure- Fig. 3 is a plan of certain of the parts shown by Fig. 1..

Fig. 4 is a perspective view of the end part of a faller constructed in accordance with my invention.

The well known upper screw A and lower screw B form the pair of screws on each of the machines.

To attain the object of my invention instead of forming the outer guiding ends a of the horizontal slides or guides 2 of the inclined character as heretofore, I now form them straight and to meet this altered formation I now make the inner surfaces 6 of the guiding grooves c in each of the fallers 3 of an inclined character, that is to say, said inner surface from the point to to the upper edge 4.0 is straight while the lower half from the point w to the lower edge w is inclined so that said groove gradually increases in depth from the point to to the lower edge 10 By this formation of the guiding surfaces 1), when the faller 3 is ascending from the position shown in Figs. 1 and 2 it will move half of its vertical path with its straight surface between w, 'w in engagement with the outer end a of the guiding bar 2 wherefore this part of its path will be perfectly upright. After travelling through this half of its vertical path, the outer inclined end 3 of the faller 3 will be in contact with the surface at of the screws a and so will commence (under the pressure of said surface of) to move. from right to left. The moving in this horizontal direction of each faller 8 is permitted by the inclined portions of the surfaces 5 from the point w to the lower edge ta to come into. contact with the end guiding surfaces or of the bars 2 so that as the screws A gradually move said fallers 3 forward, the inclined portion between w and w of the faller permits this horizontal movement because the advancing of the surfaces cl on the screws a correspond and agree with the inclination of the surface 6 between the points and 'w As is well known the lifting or raising of the fallers 3 from the lower positions shown by Figs. 1 and 2 into the higher position as shown by the faller 3 is effected or carried out'by the rotary cam 4, which acts u on the lower edge of the'faller as is shown y said Figs. 1 and 2. I

By making use of the arrangement and construction of the guides 2 with their outer guiding ends a of the formation described I have found that said guiding ends a wear evenly whenever such occurs so that they are at all times perfectly straight, and such wear is not; so apparent upon said surfaces at as it is when the inclined formation has to be maintained, because as these ends wear so also do all the guiding surfaces 1) of the fallers, wear and the sum of the wear of the fallers is represented by the wear in the multiplicity of the surfaces 6.

Such being the nature and object of my said invention what I claim is 1. A gill or faller bar having each of the bases of its guiding rooves formed with a straight part parallel to the two side surfaces of said gill or bar and the remainder of said base surface at an angle to the said parallel part.

2. A gill orfaller bar having each of the bases of its guiding grooves with a part parallel to the outer side surfaces of said bar and the remaining part of said base at an angle to the other part in combination with a guiding bar having its and guiding surfaces substantially at right angles to its longitudinal uidin surface.
