Be it known that L, dzmrir liraus, a citizen oi VlPoland, residing at Chicopee Falls, county of Hampden, and'S-tate ot 'lvlassachusetta have invented certain new and useful improvements in Steel-Cutting Machines, of which the following is a specication. n This invention relates to improvements in steel cutting devices, particularly adapted for cutting at one time a steel plate, bar, rail or the like into a plurality of parts of equal lengths. y Y j lt is the principal object ot the invention to provide a device oi thischaracter which is adjustable for the cuizting of steel or likev articles of diierent widths.

Another object ot the invention is the pro visionl of a machine oiz this type which is easilyl operated by motor or other power,` and which is simple and inexpensive, however reliable, durable and efticientl,

vwhich a shaft 11 is journaled for a disc 12,

Other objects and advantages or" my invention will become more Jfully apparent yas the descriptionV thereof proceeds by the inf spection of the vaccompanying drawings, forming a materialA part of this disclosure, and in which Figure 1 shows a machine constructed according to the present invention rin side ele'- vation. l

Figure 3 is a view partly in section along line 3 3 of Figure 1. Y

Figure 4L is a similar view in section taken along line 114-4 of Figure 2.

Figure 5 is a perspective a reciprocating saw guide.

A table 10 carries projections 9 between detail view of and for the pulley or belt wheel 13, laterally disposed tosaid disc, over which a beltA 14: is guided which is driven by a pulley V15 on a shaft 16 or' a motor or' other driving machinery. y To a projection of the bottom bar 17 of the table 10, a link 18 Vis pivotally' secured at its lower end, the upper endotwhich carries a. head 19, adapted to slide back and Jforth upon rods 2O supported in the table 10 and a leg 21 of the same. Y The upper end of kthe link 1S is slotted as at 22, and a pin 23 of the head is adapted to execute a limited verticalv movement in said slot. A link 24 is pivotallyv secured with on Speccaton of Letter sv Patent.
