IMPROVEMENT IN SCROLL- SAWING MACHINES.

To ALL'WHoM'rr MAY coNonnNf Be it known that I, WILLIAM W. Humano, of Manchester, in the county of Hillsboro, and State .of Newv Hampshire, have invented a new and useful Improvement in Scroll-sawing Machines; and I dofhereby declare that 'the following is a full,` c'lcar,-and exact description thereof, whicbjwill enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part ofthis specifica'- tion, in which- Figure 1 represents a partial 'front and side elevation ofthe machine, with all its parts adjusted. Figure 2 represents a side elevation of the dou-ble yoke.4 Figure 3 is a vertical section of thedonble yoke through the plane A B, Figurell. Figure 5 is a transverse section of the hollow beam D. Figure 6 is avertical section' o f the hollow beam through the plane of the bolt-holes E E. Figurei s'a side Aelevation of the hollow beam D. v
Similar' letters of reference indicate like parts. A
-This -invention relates to'a scroll-sawing machine, having its trusses adjusted to a hollow beam, by means of bolts easily removable, to suit the varying lengths of saws; also, to a double yoke, securely fastened to the 'front of the upright posts, said yoke supporting the steel slide, operating in combination with the sliding boxes of the hollow beam to whichthe trusses are adjusted.
Q heprominent features desirableto be 'obtained in the construction of scroll-sawing machines are lightness, strength, ease irijadjustment of the saws, and a'irm and steady movement of the boxes on their slides.
' This invention consists',rst, in the'double yoke, constructed in three parts, viz, the casting A, the casting B, andthe steel slide'C. The casting B- is'. hung on adjustable centres Within' the casting A. The slide C is also hung on adjustable centres within the casting B,`as shown` in figs. 2 and '3.
.The casting A is securely fastened, by bolting or otherwise, 'to the frontof the' posts F and I.
The use and operation ,of the double yoke A and B are as follows, viz
.When the machine is in rapid motion, the casting B has a slight lateral motion, corresponding with the strokes of the saw Gr, thus preventingr the slide C from-heating', also preventing the rigid slide N, hung within lthe casting H, on the post I, from heating. The lateral motion above referred to is produced in part by the vibration of the trusses J J, by its momentum, andthe pressure of the workagainst the teeth of the saw G, during the operation'of sawing.
I would here remark that I have practically testedthe utility ofthe yielding yoke B in the full-size s machine, which I n ow have in daily operation, and I find tliat amore close-fitting sliding box, K, can be run vupon the slide C at a highv speed, without heating the same, by means of this device, in oombination with the hollow beam, than by any other method heretofore employed. y v l The hollow beams D D combine lightness and strength, a valuable consideration in the kind of saw-frame vgenerally termed sasl1gate. The hollow beams D D have also elongated recesses, LL, admitting the wends of the trusses J J, thereby permitting them to be readily adjusted for saws of variable lengths, by means of the removable bolts E E. The resting-points'or bearings of the t'ru'sse's J J are the bolts E E, u trusses turn slightly whenever thesaiv G is tightened by means of the' nut Ml The trusses have also another 'slight turning' upon the bolts E E, at every stroke of the saw, produced both by momentum and inertia,and, being thus allowed to turn slightly, the hollow beams D D are relieved from any tendency to throw out of line the sliding boxes K K.
My invention is equally applicable tomillsavvin g of heavy logs, timber, etc.- 'Having thus described myinvention, I claim as' new, and desireto secure by LettersA Patent- 1. The double yoke A B, supporting the slide C, operating in combination with the boxes K`K.
2. The mode of adjusting the trusses J J, by means of the r bearings E E, or their equivalent, in Acombina-k tion with the hollow beams D D, substantially as and for the purpose set forth.
The above specification -of my invention signed by me, this nineteenth day of May, one thousand eight hundred and sixty-eight.
