METHlJD OF AND MEANS FOR PICKING FOWL AND THE LIKE.

Application filed April 16, 1923. Serial No. 632,257.

To all whom it may concern:

Be it known that I, VALEDO M. YOUNG, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Methods of and Means for Picking Fowl and the like, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention provides a method of and means for picking or plucking fowls or the like.

While I shall describe my invention in connection with the process of removing the feathers and hair from fowl, such, for example, as chickens, turkeys, ducks, geese and the like, it is to be understood that the invention is applicable not only to the removal of feathers, or feathers and hair, but to hair alone, or to fibers or filaments from a supporting surface.

Primarily, I provide two elements for the practice of the invention in its preferred form. First, a guide having a surface which is relatively smooth and frictionless with respect to the feathers, hair or filaments to be plucked or picked; and next, a frictional engaging surface which is held or pressed against the hair, feather, filament, or the like, while it is on said surface and then said engaging surface is moved along the guiding surface. When the frictional device presses the feathers, hair, or the like against the smooth guiding surface, the resu ting friction caused between the friction device and the hair, feathers, or the like to be plucked, is employed for the purpose of pulling or plucking said hair, feathers or the like by movement of the frictional device.

The pressure and movement of the frictional device may be obtained by a striking effect such as the movement of a piece of flexible fabric or the like, striking with components of motion toward and along the guiding surface. In the preferred form of the invention, I secure this striking action by a number of such frictional devices or strikers mounted on a common shaft and turning with said shaft. The centrifugal force throws the strikers out adjacent the feathers or the like and the rotation of the strikers about the shaft causes the longitudinal movement along or substantially tangent to the surface. It is conceivable that feathers and the like are to be removed against injury or tearing. At the same time it forms a guide or shield for the carcass to be plucked to prevent it from being accidentally moved into the range of the strikers.

In order to acquaint those skilled in the art with the manner of constructing and operating my invention, I shall now describe a specific embodiment of the same in connection with the accompanying drawings which form-part of the specification.

In the drawings;

Figure 1 is a vertical sectional view through a machine embodying my invention;

Fig. 2 is a front elevation taken from the left of Figure 1;

Fig. 3 is a horizontal section taken on the line 33 of Fig. 1;

Fig. 4 is a fragmentary sectional view illustrating the action of the machine; and

Fig. 5 is a fragmentary sectional view of a modification in which a blast of air is employed to hold the feathers in the path of the striker.

Upon a stationary frame 1 which has the supporting legs 2-3, I mount shaft 4 which is driven by any suitable means, as for example, by the pulley 5. This shaft 4 has secured thereupon a suitable hub 6 from which hub radiate the flexible strikers 7 which strikers are preferably. formed of pieces of flexible belting or other suitable material having a frictional surface adapted to engage the feathers, hair and the like to be removed. I have found, for example, that suitable rubber covered duck belting or leather belting is satisfactory for this purpose. These strikers or paddles 7 are preferably mounted with spring arms back of the same so as to insure the throwing out of the paddles under the action of centrifugal force when the shaft 4 is rotated. The spring arms 8 are backed by rigid arms. 9

. like against lateral displacement.

which in turn are secured into the hub 6. The springs 8 are arranged to back up the strikers 7 to cause them to grip the feathers,

'hair, etc., firmly as the strikers pass the guide 23 as shown in Fig. 4. These paddles or strikers 7 with their spring arms 8 and rigid backing 9 are preferably arran ed in a plurality of rows, the arms of eac row bemg offset with respect to the arms of adjacent rows so as to secure a better distribution of the striking effect. As shown, for example, in Figure 3, I have provided three rows, 10, 11 and 12, but it is to be understood that the number of rows and the distribution of the paddles in each row may be varied Without in anywise departing from the spirit of the invention.

A shield 13 is mounted at the front of the machine and to the lower edge of this shield is secured a comb 14 as is apparent from Figures 1 and 2. This comb has coarse teeth for holding the feathers, hair and the Preferably the central part of the shield 13 is hollowed out as is indicated at 15 to accommodate better the body of the fowl to be plucked. This shield 13 is preferably secured in place upon the frame 1 by means of. the side pieces 16 whichsupport the shield and comb permanently in position. These side pieces 16 reach down and are secured at 17 to the blocks 18 which in turn are secured to the front legs 2 of the machine. These pieces 16 are also secured by means of the brackets 19 to the front frame member 20. 1

Immediately below the edge of the shield 13 is provided a guide or breaker member 21 which has a head member 22 provided with a smooth convex surface 23 upon its upper forward end immediately adjacent the comb l4 and in such positionas to cooperate with the feathers, hair or the like which areto be plucked. The ide or breaker 21 is mounted for limite pivotal movement on the trunnion or bearing members 24, these trunnion or bearing members fitting in grooves or slots shown at 25 (see Figs. 1 and 2) sothatthe forward position of the surface 23 will be fixed by engagement of these trunnions with the front side of the groove .or slot 25.

.A spring 26 is connected to the lower rear part of the breaker or guide member 21 and this is adapted to retract the breaker or guide from its forward position to its rearmost position where it will be out of the path of the strikers or paddles 7. The breaker or guide member 21 is curved to conform to the curvature of the lower ortion of the shield 13 and the comb 14. 1' en the member 21 is retracted by the spring26 it is adapted to rest against the comb 1.4. I provide a lever 27 for moving the guide or breaker member 21 to its forward or operating position, this lever being actuated by a flexible cable 28 running over a pulley 29 to a suitable pedal lever 30.

The operation of the device will be best understood from Figure 4. In plucking chickens, the body of the chicken 31 is moved in close contact with the comb 14 in such a way that the movement is against the natural lay of the feathers. The feathers thus tend to stick upwardly between the teeth of the comb 14 but are engaged by the striker arms 7 and beaten or the shaft 4 on the'line indicated by the arrow 34, the resultant friction of the pressure 33 combined with the pull of the movement 34 picks or plucks the feather out of the body 31, throwing the same downwardly. The surface of the guide or breaker 21 is relieved at 35 in order to permit disengagement of the hair, feather or the like with the striker arms so that they may be thrown downwardly and clear of the striker arms or paddles 7.

In Figure 5 I have shown how a blast ofv air issuing from a number of jets 36 along the comb 14 may be employed for holding the feathers, hair, or the like out in the path of the striker arms 7. The jets 36 are fed with compressed air from a manifold pipe 37. These jets do not interfere with the action above described but assist the same.

The fundamental action involved is simple. The guiding surface 23 is smooth and presents relatively little friction with respect to the feather. In other words, the coefficient of friction between the feather and said surface 23 is low. The striker 7, however, presents a surface which is relatively yielding and has a relatively high coefiicient of friction with respect to the feather. The result is that when the feather is gripped between the high friction element 7 and the low friction surface 23 and then the high friction element 7 is moved along the surface 23 with the feather 32 interposed, a pull will be exerted upon the feather 32 which is equal to the difference in friction between the high friction engagement of the striker with the feather and the low friction engagement of the surface 23 with the feather. This action, I believe, is fundamentally new.

It is further to be notedthat the surface 23 is convex and that it is inclined in such a manner that its lower or trailing edge is nearer to the axis of the shaft 4 than the leading or upper edge. The reason for this is that the striker will not engage as firmly the base of the feather as it will the tip of the feather. This engagement increases because of the inward projection of said surface 23 which causes greater effective inertia of the striker 7 and hence better gripping toward the trailing edge than along the advanced edge to prevent crushing of the stem of the feather but to secure a good frictional grip upon the main body of the same where a largesurface is afforded.

While I have described the preferred embodiment of my invention, and while I have described its use as in connection with the plucking of fowls, it is to be understood that in this operation of plucking the feathers, the hair which exists on the body of the fowl may also be removed in the same manner. I donot intend to be limited to the precise I details shown and described.
