FLIER BLOCK Original Filed Dec. 1, 1937 George Patented Nov. 7, 1939 PAT FLIER BLOCK George W. Evans Ashley, Pa.

Application December 1, 1937, Serial No. 177,593 Renewed March 1, 1939 Claims. (01. 57-416) This invention relates to flier blocks used on spindles of spinning machine for assisting in unreeling the thread from the bobbin.

A primary object of the invention is to pro- 5 vide a novel flier wire and mounting therefor which is simple in construction and has economic as well as time and labor saving advantages from the standpoint of original manufacture as well as in subsequent use. blocks have been heretofore constructed to re movably receive flier wires, nevertheless, the construction involved is more or less complicated in the respect that a multiplicity of parts is required to hold or look the flier wires to the block, and in some cases the use of a special tool is required to set and release a locking or clamping disk or other locking means. The present invention eliminates all unnecessary parts and makes it possible to readily and quickly attach and detach the wires when the eyes become worn or cut, or when they become fouled by lint,

thereby making it possible for the operator of the machine to easily and quickly make the desired substitution of a new wire. On the other hand if the repair of flier blocks is in charge of a special department of the mill the replenishing of wires may be easily andiquickly effected without special skill. l

A further object of the invention is to provide a flier wire mounting which can be made by a simple stamping operation and which at the end of such operation is complete and ready for use in the respect that the same may readily receive the flier wires which may be made by suitable machinery in large quantities.

With the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawing, in which:

Figure l is an elevation of a bobbin showing the application of the invention.

Figure 21 is a top plan view of the improved mounting with the flier wires interlocked there- Figure 3 is a detail perspective View of one of the flier wires.

Figure 4 is a detail cross-section taken on the line 4-4 of Fig. 2.

Similar reference characters designate corresponding parts throughout the several figures of the drawing.

According to the embodiment of the invention shown in the drawing, the same includes in its organization a flier block assembly designated generally as A mounted on the spindle B iorj carrying the bobbin, the said block having suitably 'secured thereto the wire carrying plate or member C. In that connection, the invention is shown as being applied to a metallic flier block assembly of the type shown in my former Patent No. 1,823,795, dated September 15, 1931. That'is to say, themember C which'carries the flier wires W is firmly secured to the flier block to rotate therewith, the block itself being rotatably mounted on the tubular part is of thepat cut.

The plate C preferably includes a body 1 which may be'of the substantially circular formation shown having'a central opening 2 for receiving the tubular portion 3 of the mounting; The body I is preferably provided with one or more and are also preferablyarranged in a slightly NT orrics angular relation, although it will, of course, be

understood that the same result would be obtained if the lugs were parallel and the flier wires bent accordingly instead of in the manner shown in the drawing. i

The flier wires W are formed of suitable gauge wire in such a way as'to provide the resilient arms lili which are joined by the relatively looped connection l which includes the opposite shoulder portions 8. The ends of the arms 6 0pposite the loop 1 are provided with the eyes E and E for guiding the thread in the usual man; ner. The lower eye E is used to tension the thread and the upper eye tends to prevent the thread from balooning or billowing into the thread from the next bobbin.

As previously indicated, the plate elements C may be stamped by machine from suitable gauge metal, preferably brass, to form the central opening 2 and the lugs 5. The flier wires W are, of course, resilient so that the arms 5 thereof may be pressed or squeezed together for the purpose of applying the same to the lugs 5. That is to say, by bringing the arms 6 toward each other with finger pressure the same will be contracted sufliciently to permit them to be positioned beneath and between the opposed lugs 5, and the shoulders B of the loop will prevent the wire from being pulled or from sliding outwardly from between the lugs during the operation of the block which, of course, rotates at high speed as the thread is pulled from the bobbin. The mere act of compressing or squeezing the arm 6 of the flier wire enables it to be engaged and disengaged with the opposed lugs 55. The simplicity of this operation will be apparent and the facility with which new wires may be substituted greatly enhances the practical value and utility of the device since it permits of quickly making repairs without the necessity of expend ing much time or labor.

As will be apparent from Fig. 4 the lugs 55 are so made that the wires engage beneath the same or, in other words, the outer edges of the lugs overhang or overlie the wires so that they cannot be lifted upwardly from the plate. Therefore, the wires are locked against lifting movement as well as against outward sliding movement because of the shoulders 88 previously referred to, and the frictional engagement of the arms 6 with the lugs due to their divergent relation prevents them from slipping toward the center of the plate. The latter condition would, of course, only be present in preliminary assembly because after the device is in use the thread pulls it outwardly. From the foregoing it will be apparent that the present invention contemplates a flier wire mounting including only two parts, namely, the plate or block C and'the wires W. The plates 0 may be applied to existing flier blocks or they may be made and furnished as original equipment leaving only the wires to be supplied on order.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.

I claim:

1. A flier block including a mounting plate, lugs struck up from said mounting plate, and a flier wire doubled upon itself to provide divergently related resilient arm portions and a loop connecting the same, said resilient arm portions being expansively engageable with said lugs when inserted therebetween and said loop having shoulder portions for engaging the inner ends of the lugs to prevent outward movement of the flier wire relative to the mounting plate.

2. A flier wire mounting including a plate having a pair of opposed lugs struck up therefrom, and a flier wire adapted to be detachably interlocked with said lugs, said wire including a body doubled upon itself to provide divergently related resilient arms to be inserted between and to expansively engage said lugs, a looped portion connecting said arms and lying in the same plane as the arms and shoulders at the junction of the looped portion and the arms, engageable with the inner ends of the 'lugswhen said arms are inserted between said lugs to hold the flier wire against outward longitudinal movement relative to the mounting plate.

3. Aflier wire mounting including a plate comprising a body having a central opening and also provided with a radial extension, opposite lugs struck up from said extension, and a flier wire adapted to be engaged and disengaged with said lugs, said wire including a body doubled upon itself to provide divergently related resilient arms and a looped connecting portion, the portions of said arms adjoining said looped connecting portion being insertable between and expensively engageable with said lugs, said lugs having formations to overlie said arms to prevent upward movement of the flier wire relative to said plate, and shoulders at the junction of the arms with the loop engageable with the inner ends of said lugs to prevent outward shifting of the flier wire relative to said plate.

4. A flier wire mounting including a plate comprising a, body having a central spindle receiving opening and also provided with a radial extension, upstanding hook like lugs struck up from said extension at points substantially equi-distant radially from the same'side of the axis of the said central opening, and a substantially V-shaped: resilient flier wire having its apical portion formed into a flattened loop to provide shoulders for engaging behind the rear'ends of said lugs when.

the body of the wire is sprung beneath the upstanding hook portions of the lugs.

5. A flier wire mounting comprising a .plate, a pair of lugs projecting from one side'of said plate, a substantially V-shaped resilient flier wire including outwardly diverging arms insertable,

between and expansively engageable with said lugs, said lugs having portions to overlie said arms to hold the flier wire against movement at right angles to said plate, and shoulder formations on said arms engageable with the inner ends of said lugs to hold the flier wire: against outward longitudinal movement relative to said" plate.
