PT'IING-OUT MACHINE Specieation of Letters Patent.
Patented Aug. 17', 1909.
Application inea my 2s, 1904. serial No. 218,447.
To all whom it may concern:
Ee it known that I, FRANKLIN J. nnirrns, a citizen of the United States, residing at W'oburn, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Putting-Out Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
rThis invention relates to a machine for working hides, skins and leather, and is especially adapted to perform the operations of putting out, unhairing, setting etc.
Heretofore, it has been the custom to work hides by means of such a machine as is shown in my Patent No.716,1411 dated December 8, 1903, but considerable difficulty has always been experienced in successfully treating the part of the skin which lies over the end of the operating table, shown in that and other patents. The portion of the skin which lies over the end of the operating table is that portion which lies along the vback bone of the animal.
My present invention has for its object to `provide a machine which shall work the portion of the skin which comes over the edge of the table of the ordinary putting out machine independent of the machine which works the remainder and major portion of the hide or skin. rThis operation may beperformed upon the machine embodying my present invention either before or after the remainder of the skin is worked, but I have found it more satisfactory to perform this operation before the rest of the hide is worked, because if the portion of the hide along the back bone is worked after the remainder of the hide, the water etc. in the back portion is driven again into the sides of the hide and a poorly finished hide is produced. On the other hand if the back of the hide is worked first in my preliminary machine and the hide is afterward worked in an ordinary serial table machine, the water etc. which is worked away from the end of the table on both' sides is completely removed from the hide by the second operation.
Referring to the drawings-Figure 1 is a side elevation of a machine embodying my invention, certain portions being shown in section for greater clearness. Fig. 2 is a front elevation and Fig. 3, a detail to be referred to.
Having reference to the drawings, 1 is the framework of the machine and is of any convenient form adapted to support the various operating members. An operating roll or tool 2 composed of a series of helical blades of the well known form is supported in suitable bearings 11 and 12 on the frame 1 and is driven bya belt, not necessary to be shown, running upon the pulley 3 which is fast to the end of the axle L1 of the operating roll.
The skin or hide to be worked is thrown over a pad 5 having a circular contour on the side next the operating roll in order that the proper portion of the skin may engage the surface of the operating tool 2, the amount of the skin which engages with the operating tool being determined by the shape and size of this pad 5. The pad 5 is carried by a pair of swinging supports 6 and 7 which are pivoted at their lower ends to the frame of the machine. By the movement of these swinging supports 6 and 7, the skin upon the pad 5 is caused to engage the surface of the operating tool 2. The pad 5 is made of wood with a yielding covering of leather or other similar material in the manner common in such cases, and is provided with pivots 51. at each end upon which the pad may turn in relation to its supports 6 and 7. Projecting from each end of the pad 5 is a stop 52 which projects into a slot 53 in the side of the support. By this means the amount of swing of the pad 5 about the pivot 51 is limited, so that the pad cannot turn over but can still adapt itsllf slightly to the position of the operating ro 2.
To move the pad 5 in and out of contact with the operating tool, I provide the following mechanism. A shaft 3 which will be called the lower countershaft is located in suitable bearings S1 on the frame 1 of the machine and is driven by means of a chain 9 and a pair of sprocket wheels 101 and 102 located upon the shaft 4 of the operating tool and on the lower countershaft S respectively. On this countershaft 3 is placed a frictionclutch 121. In the lower part of the machine is a treadle shaft 13 upon which are a treadle 131 and a weight 139 which tends to keep the treadle in its raised position. A fork or ring 132 for the clutch 121 is attached to the upper end of an arm 133 fast to the treadle shaft 13, and two pointed pins 131.'c and 135 are screwedinto suitable holes in the sides of this ring 132. These pins 134 and 135 engage the cone 136, which in turn engages and operates the lever 122 of the fricof clutch may be used.
tion clutch 12. It is unnecessary to describe the friction clutch 12, as its construction iswell known and any convenient form The upper end of the arm 133 which carries the fork or ring 132 also carries a roller 137 which is free to turn about the spindle 133. The object of this roller 137 will be hereinafter' more fully described.
A second or upper countershaft 14 is located above the lower countershaft 3 and carries thereon a large gear 15 which meshes with and is driven by the small gear 15 on the lower countershaft 3. On each end oic this upper countershaft 14 is located a crank 161 operating a pair of connecting rods 17 which move the pad 5 toward and away from the operating roll 2 with each revolution of the upper countershaft 14.
Upon the upper countershat 14 is a stopdisk 141 having a raised rim 142 within which are two oppositely disposed depres sions or notches 143, and 144. When the treadle 131 is depressed the roller 137, previ.- ously referred to, which is carried by the upper end of the fork or ring 132, is lifted from the depression 143 in which it is shown as resting, and as the stop-disk 141 turns with the hopper counter-shaft 14, the roller 137 rolls around on the edge of the rim 142 until it drops into the second depression 144, by reason of the wei ht 139 against the action of which the tread e 131 is depressed. lli/Then the roller drops into either of the depressions 143 and 144, the cone 136 releases the clutch lever 122, and the movement of the gear 15 and the pad 5 ceases. By this arrangement of parts, it will be seen that the machine stops when the pad 5 has reached the limit of its movement away from the operating roll 2, giving the operator an opportunity to take oil' one hide and put on another before starting the machine again. This stop disk also stops the machine when the hide is in contact with the operating roll 2 and the parts remain in this position until the operator thinks that the hide or skin is suiliciently worked, and again depresses the treadle. The above-described parts of the machine stop twice for every revolution of the stopdisk 141. Of course it is to be understood that the operating roll rotates continuously and independently of the remainder of the machine.
To prevent the skin or hide from slipping on the pad 5 during the working a clamp is provided. (See more particularly Fig. 3.) At each end of the frame of the machine are placed guides 18 in which slides a clamp bar 19 which is held in engagement with the skin or hide by means of the spring 22. This clamp bar is provided with a blunt or rounded edge 191 for engagement with the skin, and holds the skin i'irmly between this edge and the upper edge of the pad 5. The
pressure ofthe clamp bar 19 is adjustable by means oil the screw 23 which passes through the ends oi the guides 13 and is held in place by a check nut 24. W hen the movable pad 5 is brought into engagement with the clamp bar 19, the clamp bar is moved back until the surface of the skin upon the pad 5 is brought into contact with the operating roll 2. An upper clamp bar 192 is fastened to the clamp bar 19 by a bolt 193 and projects over the top ol" the pad 5 when it is in working position, thus holding the hide at a second point and making it certain that the hide does not slip during the working operation.
In order that the skin may be pressed against the operating roll with the right amount of pressure some adjusting means between the crank 161 and pad 5 is necessary. To accomplish this l provide the connecting rod 17 with two end pieces 25 and 26, having screw-threaded holes therein for the reception of the ends of the connecting rods 17 which are provided with right and left hand screw-threads. By turning the connecting rod 17, the two end pieces 25 and 26 may be drawn nearer together or spread farther apart as is required. Check nuts 251, 261, are provided to keep the jarring oi the mae chine from loosening the connecting rod 17.
When the machine is in use, the operator throws a skin or hide over the pad 5 so that the portion of the skin or hide which was over the back bone of the animal comes over the pad 5 between its upper and lower edges. He thon presses down the treadle 131, which causes the clutch 121 to operate and starts the rotation ot the gear 15, thus bringing the movable pad 5 into engagement with the operating tool 2, while the clamp holds the hide firmly against the pad 5. When the stopdisk 141 has completed half a revolution, the roller 137 drops into one ot the depressions in the stop disk and causes the gear 15 to cease its rotation, thus holding the hide or skin in Contact with the operating roll until the operator again depresses the treadle. The pad 5 then moves back out of the way of the operating tool, so that the operator may remove the hide and repeat the operation.
