Description

UNITE STATES PATENT OFFICE FERDINAND soHoETTLE, or PHILADELPHIA, (rENNsYLVANIA.v
IMPRovEMEN'r IN sHEARs.
Speciiication forming part of Letters Patent No. 122,333, dated January 2, 1872.
SPECIFICATION.
I, FERDINAND SoHoET'rLE, of the city and county of Philadelphia and State of Pennsyl-l vania, have invented certain Improvements in Stationary Shears for cutting paper, pasteboard, and other light material, of which the following is a specification:
My invention relates to an improvement in the shea-rs used by paper-box makers and others 5 and consists of a lengthened adjustable journal-box in combination with a tighteningbolt or journal.
On reference to the accompanying sheet of drawing, Figure l is a side view, showing the shears, journal-box, and tightenin g-bolt. Figs. 2 are side and end views of the adjustable journal-box. Fig. 3 is a top view of Fig. l. Fig.
.4. is a section through the journal-box, upper knife, and the ti ghtenin g-bolt. Fig. 5 is a view of the tightening-bolts and nuts.
General Description. M
A and B are the top and bottom knives of a pair of shears. The bottom one, B, is attached in the usual manner to a table or stand. C is an adjustable journal-box, which is secured to the frame E of the table by bolts passing' through vertical slots I) b in the butting piece of the box. B is abolt or journal which turns in the box C. Its inner end a" is reduced in diameter to correspond with the opening in the eye or swell of the upper' knife A, so that when the nut a Vis screwed up the knife is firmly pressed against the shoulder formed by the reduction in the diameter of the bolt. The outer end of the bolt D is shorter than the adjustable journal-box C, to provide for the wear ot the eye of the knife A and the end of the box C against each other. The nut a secures the knife A to the bolt D. The nut a on the opposite end of the bolt keeps it from Working out of its journal a-nd also serves to take up all 'lost motion oi' the knife A, andthereby prevent it from wabbling. The nut a is a set-nut, to keep the nut a. fromloosening or backing olf While the bolt D is turning. The adjustable joiu'nal C can have more or less shear given to it by means of the vertical slots b b. Simply 4backing or loosening' its bolts enables it to be raised or lowered to any req uired degree at will, in which consists its adjustability. The upper knife A or its lever has its boss or eye of the same diameter as the endet' the journalbox O against which it works. Its action is entirely distinct from that ofthe lower knife B. It turns With the pin D as a center, while the knife B is stationary on the table.
The pin D turns or rocks in the journal-box C, and, as before mentioned, its larger diameter is shorter than the box C, whereby, by inea-ns ot' thenuts a. a", the knit'eAca-n be nicely adjusted, and all lost motion caused by the Wear and tear of the eye against the end of the box taken up.
I claim as my invention- The upper knife or lever A, the adjustable journal-box C, and the bolt or journal D, when constructed, arranged, and operated as shown and described.
In testimony whereof -I hereunto sign my name.
FERDINAND SCHOETTLE.
