IMPROVEMENT IN MACHINES FOR SLICING CORK-WOOD.

Specification forming part of Letters Patent No. 45,310, dated December 6, 1864.

To all uhom it may concern: l

Be it known that I, HARRIS BoARmIAN, of l Lancaster township, in the county otl Lanl caster and State of Pennsylvania, have inl vented new and useful Improvements on a l Machine for Slicing Cork-Wood; and I do` hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a perspective view of themachine. A is the circular blade orcutter on its u shaft and bearing F, with its strappulley E mounted on the standard or table (l, with its gage l), slots, and setlscrews B B2, the carrying rollers on their shaft in place with the edge of the cutter between them.

Fig. 2 is a vertical section of said rollers and knife or cutter.

The drawings plainly illustrate the construction of the machine, and its operation is readily l understood.

By means of the strappulley E on the shaft of the cutter-plate any desired speed is imparted by a strap or belt from other machinery in motion by any power at command. The cutter A enters partially between the rollers i B B2, which rollers move freely on their supl porting-shaft, and are used instead of a plain iiat table for feeding the cork-wood to theknife, being of equal diameter to near the knifel or blade, Where they have a raised beveled edge on each side of the knife, terminating with parallel faces separated from each other, the thickness ot' the intervening blade of the l variously contrived.

cutter, as shown by Fig. 2. 'Ihe object of the short beveled inner or central ridge formed by them is to prevent the cork-wood from its tendency to bind and consequently heating the blade, and thereby impairing its temper and durability. The action tends, wedge-like, to facilitate the slicing', as well as the motion of the rollers to aid in the feeding of the cork to the knit'e. As the corlcwood is always more or less curved, the rollers act in the Inanner of a curved moving table, besides the separating action ot' the beveled edge referred to.

The gage for regulating the width or thickness of the slice is nothing new, and may be I therefore do not claim the gage D and cutter-plate A and its bear- 1n gs as any part of my invention, as such may have been in use substantially the same; but

I am not aware that carrying or feed rollers have ever been used, when constructed in the manner and for the purpose described and shown, and the utility and advantage in their i employment is found to be of great practical value, and a highly desirable improvement in the. operation of the machine.

What I claim as my invention, and desirevto secure by Letters Patent, is

The carrying-rollers B B2, when constructed as described, in combination with the circular vertical knife blade A, arranged and operating substantially in the manner and for the purpose specitied.
