TURNUSTG TABLE FOR gKIN-DRYING PLATES.
Application filed June18, 1923. Serial No. 646,221.
The invention relates to apparatus for the manufacture of leather and more particularly to means for facilitating the setting out of skins upon drying plates. In one process extensively used in the manufacture of leather the skins are stretched and dried by coating the same with adhesive and then pasting upon drying boards. In affixing the skins to theboards it is necessary for the workmen to use a scraping or settingout tool by which the thick portions of. the skin are stretched out and thinned while the naturally thin portions of the skin are condensed and somewhat thickened. Such operation requires that the plates should be arranged horizontally and, to reachall p'ortions of the skin, the workman usually mounts the table on his hands and knees. The drying plates areformed of comparatively thin paper board having glazed opposite surfaces, and therefore, to avoid injury to these boards they must be supported through their entire area during the settingout operation. Furthermore, to increase the capacity, it is desirable to utilize both sides of the board, which necessitates reversing the same on the table with care so as to avoid nnury to the mounted skin.
To facilitate this setting-out operation.
and mounting of the skins upon opposite sides of the board I have devised a construction of turning table by which a plate, after the mounting of a skin on one face thereof, is quickly reversed and deposited on a table on which it is supported during the mounting of the second skin. The invention therefore consists in the construction of this turning table as hereinafter set forth.
In the drawings:
Figure 1 is a longitudinal section through the table;
Figure. 2 is a plan view thereof;
Figure 3 is an end elevation;
l ig'uro l is a view similar to'Fig. 3 showing a modified construction.
My improved turning table comprises a platform A whichis mounted on a suitable framework B resting upon the floor. At. one edge of this platform there is mounted in bearings C a rock shaft D, which as shown is formed of a beam portion D and stub shafts D at opposite ends thereof. Projecting laterally from the beam portion are a series of arms E, preferably formed of T bars, which, are attached to the beam at one end and project over the platform engaging grooves F therein. The head portion of the 'T' is substantially flush with the surface of the platform and, as its width issubstantially that of the groove, an uninterrupted surface is presented for the support of the plate. G is a connecting bar between the free ends of the arms E, this being preferably in the form of an angle bar. H is a levr arm attached to one end of the shaft D, and I is a counterwei ht arm secured to the opposite end of said shaft. Thecounterweight is adjusted to balance the structure so that the rocking of the same can be easily accomplished by a movement of the lever H. J is a second platform which isarranged adjacent to the platform A on the opposite side of the rock shaft D, said platform J presenting an unbroken supporting surface for the plate.
lVith the construction as described the plate is first placed upon the platform A over the arms E and while thus supported the workman mounts a skin upon the upper surface thereof. As soon as this operation is completed the lever H is actuated to quickly rock the frame, thereby turning the plate and depositin it in a reversed position upon the platform J. The workman may then proceed to the mounting of a second skin upon the reverse side, after which the plate is lifted from the platform and is transportedv to the drying rack.
This simple construction of" apparatus greatly cxpedites the work and also avoids injury to the mounted skin during the op eration on the reverse side.
If desired, the arms E may have attached thereto a continuous plate K, as shown in Figure 4, which will provide uninterrupted support for the mounting board.
What I claim as my invention is:
1. The combination with a platform having two sections, one of said sections having grooves and each. corresponding in area to a skin mounting plate, of a rock shaft extending between said sections, arms projecting from said rock shaft and engaging said grooves in one section of said platform, and means for rocking said shaft to turn the plate from the grooved section of the platform onto the other section.
2.-The combination with a platform having two sections, each corresponding in area to a skin mounting plate and one section extending hetween having zygroovecl siirleee of 2 rock shaftexuencling between said sections, rook arms extending laterally from said rook shaft and of an angular cross-section, said rook arms engaging the grooves in one section of the platform With the head portions of the angle flush with the upper face of the platt'orin, and means for rocking said shaft to turn the plate 'lroznthe grooved section to the other section of the platform.
3. The combination with 11 ]3l2ttf01111 having two sections each corresponding in arezi to a skin mounting plate, of a rock shaft said sections :angle bars 7 grooved section an angle lJZLDCOIlHQCtlIlg the outer ends of with grooves for receiving said angle bars with the hoods hereof flush with the upper surface of the platform, a counterweightattached to said shai'it for counterbalavneing said arms, and a lever for rocksaid shaft to turn a plate from the ofthe platform to the other section thereof.
In testimony whereof I ziffix my signature.
