LEATHER-GLAZING MACHINE.

Application filed April 15, .1925. Serial No. 23,375.

[This invention relates to leather glazing machines, and an object of the invention is to provide a machine which will glaze a relativelylarge area of leather in proportion'to the area of a hide or leather glazed by leatherfglazing machines of the approved types now 1n use.

In theapproved types-nowin use, a single glass or agate cylinder is used and the hide isrnoved about upon the supporting platform and engaged by the glazing agate caus ing several movements of the hide before it is,.,completely glazed.v

It is-an object of the present invention to providea machine wherein an entire hide may be glazed by a single manual operation, namely, that of feeding it to the glazing. ma chine which includes a plurality of staggeredlyarranged agates or glazing cylinders irganged so as to glaze the entire area of the Another object of the invention is to provide a glazing machine. as specified, in which manually operated means are providedfor regulating the pressure of the glazing cylinde'rs'upon the leather.- A

Other objects of the invention will appear in the following detail description, and in theaccoinpanying drawings wherein Figure 1-is a side elevation of the improved glazing machine showing parts thereof in section. I

Figure 2is an end elevation of the improved glazing machine.

; Figure .-3'is a detail section on the line 33 of Figure 2. i f

Figure -5.is an enlarged detail illustrating the mounting of oneflof'the glazing cylinder or agates. 1;

. Figure ,6is-.a detail view. Referring more particularly to the drawings, the improved leather glazing machine includes a supporting structure 1 which has a table 2 supported thereabove and hingedly connected at one end by hinges 3 to the sup porting structure. "Expansion spiral springs 4: are provided at the edges or sides of the supporting structure 1 and they engage against the undersurfaoes of the horizontal portions 5 of the substantially Z irons which are attached to and extend along the side edges of thetable 2, and they engage against the horizontal portions of the Z irons .6 which are attached. to the supporting struct-ure 1. The springs 4 one of which is positioned one at each side of the table structureare coiled about suitable bolts 7 which extend through the Z irons 5 and are held against movement relative to the Z irons andthe table 2 .by'suitable nuts 8. The bolts? project downwardly through pivotally mounted spring tensioning members 9 which are pivoted as shown at 10, to suitable brackets car.- ried by the table structure and have their outer ends beveled, as shown at 11. Slidabl'e wedges 12 are slid-ably supported by the sides of the supporting structure 1 and they are connected by suitable angle plates 18 to a cross bar 14,which extends across beneath the supporting structure. The cross bar 14 is connected intermediate its ends by means of angled bars 15 to a yoke 16, which yoke is provided with an internally screw threaded head 17 through which the feed screw 18 extends. A suitable crank lever 19 is connected to the feed screw 18 for rotating the feed screw and for'moving the cross bar 14: and the wedge members 12 laterally across the supporting structure 1. The wedge members 12 move in slots 20 in the side rails 21 of the supporting structure 1and their beveled surfaces 22 riding over the beveled surfaces 11 of the spring tensioning members 9 will move the table 2 on its hinges towards or from the upper surface of the supporting structure, tensioning or lessening the tension upon the springs 4 which resilientlyurge the table structure 2 outwardly from the supporting structure1.-

. The table structure 2 has its upper surface cut at inclinesat each edge longitudinally, as shown at 22, .in Figure 5 of the drawings.

.and itssurface is faced with a. facing 23 oi l.eather.- i 1 ,Bearing structures 24 are supported by suitable supporting structure 25 above the table 2, and at each end of the table. A shaft 26 is rotatably supported by the bearings 24, and it carries a drum 27 which drum has'a plurality of agates or glazing cylinder 28 attached to its outer surface in longitudinally extending rows. The cylinders 28 in one longitudinal row are disposed staggeredly with respect to the cylindersin the other rows, so that the cylinders in each row bridge the space between the cylinders in the adjacent rows. The cylinders 28 are constructed of glass, agate or other suitable material, such as used in the glazing of leather, and they are attached to the drum 2'7 by suitable bracket or bearing structure 29 each of which comprises se Jarable sections 30 clamped together by suitable bolts 31 to permit removal of the cylinders whenever necessary.

The table structure 2 is reinforced by the angle irons 32 which engage across the edges and beneath the bottom ofthe wood body of the table for bracing it, and the table is further braced by the transverse bolts 33 extending therethrough. The bolts 33 are removable to permit changing of the table structure, if desired, and the leather facing 23 is also removable so as to permit its replacement when it becomes worn.

In use, power is transmitted to the shaft 26 from "any suitable prime mover (not shown) which rotates the drum 27 and the table 2 is adjusted relative to the cylinders 28 by means of the adjusting screw 18 in accordance with the thickness of the hides to be glazed, and the hides are passed over the table structure 2 and between the facing 23 and the glazing agates or cylinders 28 permitting the glazing of the entire surface of the hide by its feeding through the ma chine and eliminating the movement of the hide above overthe table to bring various parts thereof in active relation to the glazing cylinder, such as is done in approved types of glazing machines now in use, thereby saving considerable time and labor in the proper glazing of hides.

It is, of course, to be understood, that the invention may be constructed in various other manners, andthe parts associated in different relations, and therefore, we do not desire t0 be limited in any manner, except as set forth in the claims hereunto appended.

What we claim is 1. In a leather glazing machine, the combination of a supporting structure having a drum transversely journaled thereon intermediate its ends, a plurality of glazing cylinders detachably carried by said drum, a

porting structure and extended inwardly from one end of said structure, pivoted wedge members coengaging with the slidable wedge members, said pivoted wedge members being adjustably connected to said tension rods for retaining said receiving table in a fixed position relative to said glazing cylinders, said cylinders being disposed in parallel rows in staggered relation to overlap in their surface engaging paths of travel substantially as described.
