as U. 8. Patent No. 2,376,500, granted May 22,
A further object of my invention is to provide a drum for treating skins which has a series of grooves so arranged upon the face of the drum which will cause the heat to be distributed more evenly upon the hairs of the skin to prevent such hairs from being singed. V
A further object of my invention is to provide a plurality of substantially V-shaped grooves in combination with additional circumferential grooves and parallel straight grooves, the aforesaid grooves being of different depth, so that the skins being treated beneath the face of the drum will obtain a better finish.
For a fuller understanding of the nature and objects of my invention, reference is had to the following detailed description in connection with the accompanying drawing in which:
Fig. 1 is a side elevation of a skin treating machine showing the drum in relation to the rest of the machine.
Fig. 2 is a view of a fragmentary portion of the cylindrical surface of the drum developed into a plane. a
Fig. 3 is a section taken through line 3--3 of Fig. 2.
Fig. 4 is a View of a fragmentary portion of the cylindrical surface of a modification. of the drum shown in Fig. 2 developed into a plane.
Fig. 5 is a vertical section taken through a central portion of the drum shown in Fig. 1.
Referring to the drawing, numeral mindicated a machine for treating skins and the like, comprising a frame I l having a table 1 2 in which a blanket I3 is mounted, movable vertically.
An ironing drum I4, having a hollow shaft I5 is rotatably mounted in bearings l5 upon the table l2. The ironing vdrum I4 is provided with a central pipe 55 in which there is a series of holes 56 for gas for heating the interior of the drum l4. Through the central portion of the drum there is a shaft l5 also having a series of holes 58 which permits the heat to enter the interior of the drum, since the drum is made of metal the heat is readily transmitted to the ,wardly toward the rear of the machine.
circumferential surface of the drum. Instead of gas, it is a simple matter to replace gas heat with electricity and use thermostatic means for automatically controlling the heat.
The frame ll comprises a pair of parallel side walls I! which have low front portions I 8 and high rear portions IS. A pair of parallel bridge members are mounted across the low portions l8 and are connected to the side walls I"! in unitary relation. The bridge members 2'0 have inclined sides extending upwardly from the outer faces of the side walls I! terminating in brackets on which the table l2 has been fixed.
The rear portion of the table I2 is formed with a large rectangular opening in which the blanket I3 is mounted. A bar 22 extends'across the rear of the rectangular opening, bar 23 extends across the front of the central part of the table I2 with bar 24 slightly higher than, bar 23 and placed between bars 22 and 23, all the bars being parallel to one another. The blanket I3 is rotatably mounted on bars 22, 23, and .24.
The rear portion of blanket I3 is sloped down- The blanket 3 may be made of a sheet of felt material as shown, or of a suitable cloth which may be reinforced and supported by a wire mesh belting 26 of the same width as the blanket l3 so that it assists in tautly supporting the blanket 13. The means for lifting and lowering the blanket 13 comprise a link which is pivotally connected by a pintle 23 to a bracket. The link 21 extends downward and rearward and pivotally connects with a lever 30. The front end of the lever. 30 terminated in a pedal 3| by means of which the front end of the lever may be depressed.
As shown in Figs. 2 and 3, the drum is has a plurality of substantially L -shaped grooves as, the agoices being positioned in offset relation with the middle of the drum so as to cover the entire circumference of the drum with the grooves. As shown in 3, the grooves 33 are of triangular cross section, each groove having a radially positioned wall is and a wall t5 positioned at an acute angle to the radial wall id. The surface of the drum id has, in addition to the V-shaped grooves a series of parallel uniformly spaced circumferential grooves -lii and'a series of parallel longitudinal grooves ti, spaced apart the same distance as the circumferential grooves, thus creating a series of squares 3%. During rotation of the drum it, these grooves serve to circulate the heated air with the outer air within the grooves and cause the hairs of the sxin to raise and stretch while an evenly distributed heat is applied to the skin.
Referring to Fig. 4, numeral it represents another modified drum very much like the drum shown in Fig. 2, except that the longitudinal grooves ii! are uniformly spaced apart a lesser distance Within the circumferential grooves the large V-shaped grooves 5i being similar to the V-shaped grooves of Figs. 2 and 3. As shown in Figs. 2 and 3, the grooves it and ii are cut with straight walls. so that in section they rectangular as seen Fig. 3, however, these grooves may be made V-shaped instead of being cut vertically, if so desired.
I have found that drums constructed like those shown in Figs. 2 and 4 will stand exceptionally long wear, thus permitting the drum to remain in constant use so that production will not cease for necessary repairs. It should be understood that the difierent drums listed in the drawing and described in the specification may be designed for application upon all of the well known machines for treating skins of diiferent animals.
It is obvious that various changes and modifications may be made in the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
I claim:
1. A skin treating machine comprising a circular drum, heating means within said drum, said drum having a plurality of substantially V- shaped grooves, the junction point of which is positioned on either side of the circumferential medial line of said drum, a series of parallel straight circumferential grooves crossed by a series of parallel straight grooves in said drum, said grooves being less in depth than said V-shaped grooves, said straight and V-shaped grooves being uniformly spaced around the entire drum.
2. A skin treating machine comprising a circular drum, heating means Within said drum, said drum having a plurality of substantially V- shaped grooves, the junction point of each is positioned on either side of the circumferential medial line of said drum, a series of parallel straight circumferential grooves crossed by a series of parallel straight grooves in said drum, said parallel grooves losing spaced apart a lesser distance than said circumferential grooves creating rectangles, said s raight V-shaped grooves being uniforn 1y spaced around the entire drum.

4. A skin treating machine comprising a circular drum, heating means within said drum, said drum having a plurality of substantially V shaped grooves, the junction point of which is positioned on either side of the circumferential medial line of said drum, a series of parallel straight circumferential grooves crossed by a series of parallel. straight grooves in said drum, said parallel grooves having sloping walls spaced apart a lesser distance than said circumferential grooves cr ating rectangles, said straight and V shaped grooves. being uniformly spaced around the entire drum.
