IMPROVEMENT I-N SINGLEPMGHINES.
l p ."tlgt tlgehixlt mettiti in in this: Etnias @attinenti 'mating part nf the same.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, LYMAN JENNINGS', ofWinchendon, in thecounty of Worcester, an'd State of Massachu# cette, have invented 'a new and useful Improvement in Shingle-Machines; and I do hereby decla-re that the foll Alowing is a full, clear, and exact description thereof',l which'will, enblebther's Skil-led in the art to make and use the same, reference being had to the accompanying drawing,- forming part of thisspeciiication, inwhich- Figure 1 isa frontl view of my improved machine. Figure 2 is verticalcross-section ofthe same, 'through theline v a: of fig. 1. Similar letters of reference'indicate like part. Y This invention'V consists in the horizontal .action of the cutter and Velevating-bloclc rest, together with the mechanism conducting to the operation ofthe same, as will hereinafter be fully set forth.
In the machines heretofore made, -the cutter operated with an Voblique or shear'cut, which was disadvan tageous in-'many respects. I p l In my improved-machine thegknifeslides horizontally, keeping the edge of the knife in thesame line, and the block-rest is made-to rise and bear the shingle against the cutter -in an even and equa'ble motion, which conducos to theproduction'of good work.
In the accompanying plate of drawings the general frame of the machine is shown at A A A, &c.,.and upon which the mechanism is aixed. This .frame is supported upon legs B B.
Y' The cutter is composed of several separate parts, g g g, tc., which are,.b,olted to a back plate, b, as shown,
the said back plate sliding in a grooved metal bar, a, which is bolted horizontally across the frame A, as shown.
IThe upper edge'of the back plate is held in the said groove-by means of vertical guide-bars ff, at-'eacb end of the cutter, and which are bolted to the back plate.'
The lower ends of these bars slide in a grooved bar, e, wbiehis bolted to the. frarneA, and is parallel with the bnr a. The back plate 5 is connectedwith a rack, c, which slides with-easy contact within agroover in the 'upper face of the bara, as sho\vn. The arm h which connects th'e back plate with tberack is bolted to both, and is bent over and upon the rack, as'shown.
The pitman orconnecting-1od which actuates .the cutterl to and fro, is in practice connected with aistrapjoint to aj wrist-pin, projecting'from the back plate, as represented by the knob j. p
' The'block-rest D is movoil up-and downwith a reciprocating motionby means of thepinions d d, which engage with the rack-teeth c c atlixed to the lifting-uprights CC, as shown. Theseuprigbts pass'througb `mortisesjin the block-rest D, and are held there by screw-boltspp, as show-n.
Guide-blocks E E, having recesses and plates G G, serve to keep the-racl s c k engaged with the pinions. These guide-,blocks :irebolted to the frame Ain any suitable manner. The pinionsY cl alare upon the same' shafts m m as the cog-wheels I I, which latter engage with the rack C, and are therebyrvrotated when the cutter is drawn to and fro. The shingle-block is shown inred at H. Thegauge l is `ot` thelusualconstruction.
` When the cutteris drawn to and fro by any suitable application of power, the block-rest and block are drawn upward against the edge ofthe cutter, whichsliees oli' a thin portion suitable for shingles, 'bucketfbottomm boxstui, and the like,4 i The block lislfed into the cutter by hand.`
This machine is easily operated, and cuts the wood ina. more desirable manner than the shear-cut machines.
The cutter being composed. otl'g'separate parts, g g g, Ylite., is 'expeditiously and cheaply repaired, by the removal'ot the grapple Vpart and: aiir'rng Vanother in itsl place. The rst cost of the whole cutter when thus .made `is-.also less than one formed. of one continuous piece.
Having thus described" my inventiom'I claim as new, 4and desire to secure by Letters Patente- 4-The combination ofthe horizontally-sliding cuttersg g g and therack c with the wheels I I, pinions` d d,
racks c k, for operating the sliding block-rest D, as described. Y c
