Definitions

  • This invention relates to a device for stretching hides from fur animals, such as minks, martens, sables, and foxes. Obviously, though, the invention may be used for processing hides from other animals, which require to be stretched.
  • the task of this invention is to provide a device whereby the operations listed herein above can be fully automated.
  • a device for stretching hides from fur animals such as minks, martens, sables, and foxes, characterized in that it comprises a base, a hide holder or support body of elongate shape and articulated barndoor-like to said base in a detachable way, a hide being effective to be laid on said holder or support body and secured to said base with the end closest to the articulation point, a backing or biassing element adapted to be superimposed on the free portion of said support body and being slidable with respect thereto between a position near said articulation point, wherein said backing element underlies that end of said hide opposite to the end thereof secured prior to the stretching operation, and a position spaced apart from said articulation point, a carriage arranged to be movable in a parallel direction to said support body, actuator means for reciprocating said carriage between said two positions,
  • this device comprises a base 1 of box-like design and being elongated horizontally, on the front whereof are arranged control pushbuttons, generally indicated at 2.
  • a baseboard 3 from which a pin 4 extends vertically upwards.
  • a pin 4 extends vertically upwards.
  • a horizontally elongated body 5 which tapers towards its free end.
  • the body 5 is flattened and has its top 5a and bottom 5b edges rounded off. Whereas the bottom edge is horizontal, the top edge slopes down from the articualtion point towards the free end.
  • the body 5 constitutes the support or holder on which the hide, after it has been stretched, will stay attached.
  • a backing or biassing element 6 which comprises a collar 6a having a complementary shape to that of the support and from which there extend two extensions 6b and 6c adapted to cover the edges 5a and 5b of the support 5 over a certain length.
  • the extensions 6b and 6c are interconnected together by an annular portion 6d which, along with the collar 6a, defines a shoulder 6e.
  • the backing or biassing element 6 is provided . with an additional extension 6f which covers the bottom edge of the support 6 and has one end formed with a through hole for the insertion of a vertical pin 7 which, in the inserted position thereof, protrudes beneath the extension 6f.
  • Figure 4 shows a sectional view through the end of the extension 6f.
  • the terminating portion 5c of the latter is inserted through the extension 6f.
  • the active means of the device are accommodated.
  • Such means comprise a pneumatic or air-operated cylinder 8 which is mounted on the base 1 such that itsllongitudinal axis is parallel to the support 5.
  • the rod of the cylinder 8, indicated at 8a is connected to a carriage or slider, generally indicated at 9.
  • the carriage 9 is composed of a plate 10 therewith, by means of four tie rods arranged in cruciform configuration, is made rigid a further pneumatic or air-operated cylinder 11, aligned with the cylinder 8.
  • the carriage 9, upon actuation of the cylinder 8, is reciprocated along a rail 12, on which the carriage can roll by means of a pair of wheels 13,14 mounted idle on the plate 10 and in the base of the cylinder 11. Expediently, the wheels are caused to run in a longitudinal groove 15 of the rail 12 to avoid lateral deflections of the carriage.
  • two tie rods, 16a and 16b extend in a vertical plane, whereas the other two, 17a and 17b, extend in a horizontal plane. On the latter is guided slidably a shoe 18 attached to the rod 11a of the cylinder 11.
  • the links 19a,19b are swivel connected with two-arm levers 2 0,21, said levers being pivoted at side wings 10a,10b of the plate 10.
  • the arms 20a, 21a of the levers 20,21 are articulated under the wings 10a,10h and connected to the links 19a,19b, the other two arms 20b,21b being articulated above said wings.
  • Said other or upper arms 20b,21b are relatively coupled to the lower ones 20a,21a by means of pivot pins 20c,21c which are set rotatable in the wings 10a,10b, to which pins the arms are keyed.
  • the lower arms 20a,21a - are articulated respectively below the link 19a and above the link 19b, so that they extend in one and the same horizontal plane.
  • respective jaws 20d,21d whose faces are facing toward the backing element 6 and mate the shape of the annular portion 6d.
  • the device is completed with a strap 22 formed with aligned holes 22a, which is affixed to the plate 10 and projects cantilever-like above the carriage 9 and parallel to the running direction of the latter.
  • FIG. 3-5 A hide 23 to be stretched, while still in a tubular form and indicated in dash lines in Figures 3-5, is superimposed on the support 5 and backing element 6 and secured at one end by nailing or stapling. This operation may be carried out separately, before the support is engaged with the pivot pin 4.
  • the cylinder 8 is actuated in the direction-to bring the carriage 9 to its right travel limit, as viewed in Figure 1.
  • the cylinder 11 is actuated which, up to-now, had been in its retracted condition with the jaws 20d,21d in the opened condition.
  • the actuation of cylinder 11 controls the closing of the jaws onto the annular portion 6d of the backing element 6.
  • the inventive device fully achieves its objects.
  • the hide stretching operations are greatly speeded up.
  • the hide itself does not get damaged.
  • the extensions 6b, 6c ensure an evenly applied tension and contribute to holding the element 6 guided.
  • the hides may be secured to the support by providing clamps incorporated to the support itself.
  • the device may be adapted to fit different hide lengths by providing linearly offset holes 5d for engagement by the pin 4.
  • the articulation of the support in one of said holes also allows the amount of stretching to be changed while keeping the stroke length of the cylinder 8 constant.
  • the amount of stretching may be determined by adjusting the stroke length of the cylinder 8.
