BAND SAWING-MACHINE.
f SPECIFIGA'DON forming part of Letters Patent No. 252,043, dated January 10, 1882.
` Application filed November 5, 1881. (No model.)
To all whom it muy] concern:
Be it known that I, Lnwis F. KETTLER, a citizen of the United States of America, residing at New Bremen, in the county of Auglaize and State of Ohio, have invented certain new and useful Improvements in Band Sawing-Machilies; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or figures ofref erence marked thereon, which form a part of this specification. Y f
This invention has relation to improvement-s in band-sawing machines; and it consists in the novel construction and arrangement of the y various parts of which it is composed, whereby the logs of wood to be sawed are adjusted and fed to the saw, at the same time providing a means for adjusting the pulley over which the endless saw revolves, thereby tightening or loosening the same, as required, all of which will be hereinafter more fully explained.
The annexed drawings, to which reference is made,fullyillustrate my invention, in which Figure 1 represents a vertical sectional view' of my improved sawing-machine.V Fig. 2 rcpresents a longitudinal sectional view of the same. Fig. 3 represents a side view. Fig. 4t represents a cross-sectional view,'and Fig. 5 is a sectional detail View. u
The letter A designates the base of the machine, which rests upon the ground, and consists of two side beams, a a, and braced by cross-pieces a a. At one end of the frameA arise two standards, a? a?, and connected at the top by a cross-bar, a3, and secured by one end to said standards,4 are two horizontal bars, a4 a, to the outer ends of which are secured two vertical bars, a5 a5, which are connected at the top'by cross-bar a6.
B indicates the upper band-pulley, having on one side a lian ge, b, and a periphery7 formed of an elastic band, b', and journaled at b2 on either side in the adjustable cross-bars b3 b3, the inner ends, b4 b4, of which work in slots b5 b5, made in the standards aforesaid, and serve as hinges for said bars, while the outer ends, b6 be, are free and work in slots made in the vertical bars a5 a5, and are provided above and below with wedges 117 I.
C indicates the lower band-pulley, journaled in the side beams, aa, and provided witha driving-pulley, c, and a side liangmc, and alsoa-n elastic periphery, c2, around which the saw c3 revolves. i Said lower pulley', C, is placed within a casing, c4, that is secured to side beams,
of with wheels d3 13d3 d3, and on the under side with a rack-bar,d, that engages a pinion, d5, on a shaft, hereinafter mentioned. On the upper face of the truck aforesaid are journalbearings d als, in which are placed the journals Z7 d" of aroller, E, that is provided with teeth e for griping the log in conveying it to the saw.
On one end of the journal all olI is secured a toothedwheel, e', in which engagesa pawl, e2, pivoted to a hand-lever, e3, that has its lower end, e4, loosely connected to the journal aforesaid. To one side of the block D are secured brackets e5 e?, in which is journaled a shaft-,66, having a crank, e7, on one end, and a bevelgear wheel, e8, on the other' end, that meshes with a larger gear-wheel, e9, on a shaft, em.
F indicates a carriage, consisting of side pieces,ff, and cross-piecesff, and provided on either side with flanged wheels fzfzfzfz, that travel upon the side beams, a a. Said carriage has secured thereon a block, f3, of similar construction to the block D, above described, and is provided withta truck, f4, having wheelsf5f5f5f5, and on Vits under side a rack-bar, f6, that engages a pinion, f7, on the shaft el.
The pinion f 7, above mentioned, is constructed with a hub, g, on either side, which are journaled in the block f3, and have a square opening in the center to engage the square shaft el". Also, the pinion d5 is provided with a hub,
IOO
g', that is ]'ournaled in the block D, and connects the larger gear-wheel e9 with said pinion, thereby ca using both to revolve together when operated.
The shat'tcl",l1ereinbefore mentioned, is made square, as shown in the gures of the Kdrawings, and passes through the blocks D andf,
' and is loosely secured at oneend to the crosspiece g2 of the machine and at the other end to the block D. A
Having thus given a description of the various parts of which my sawing-machine is constructed, I will proceed and explain the operation.
The power is applied to the belt-pulley c, thereby revolving the band-pulley C, and carrying therewith the band-saw c3, at the same time communicating motion to the upper pulley, B. The saw being in motion, a log is placed upon the roller E, (one end.) and the opposite portion rests upon the truck f4, and by means of the hand-lever e3 is drawn forward, at the same time carrying the carriage F therewith, until suticiently across the teeth of the saw, after which the crank e7 is revolved by the operator, thus, through the medium of the bevel-gear e8, causing the gear-wheel e9 to revolve, and carrying therewith the pinion d5 and pinion f7 simultaneously, thus imparting motion to the trucks d2 and f4 by said pinions operating with the rack-bars d4 and f6, and carry therewith the log until a portion is severed by the saw c3 and rolls from the table by the same being slanted as described, after which the crank e7 is reversed and the trucks are returned to the first position, and the 1ever e3 again being operated again sends the log forward to be sawed.
It will thus be seen by the foregoing description that I construct a band sawingmachine with the pulleys provided with rubber, and adjusting means for tightening or loosening the saw, and the construction of the different parts is simple, and easily operated. Also, it will be observed that my machine can be used for sawing the tops of trees as well as the trunk, and by placing the trucks or attaching similar ones lengthwise with the blade ofthe saw my machine can be used as a lumber-saw.
Having described my invention` whatIclaim, Iand desire to secure by Letters Patent, is-
In a band sawing-machine, the combination of the truck d2, mounted on the blocks D, operated byv the pinion d5, engaging with the rack-bar d4 of the truck f4, traversing the carriage F, and the pinion f7, engaging withthe rack-barf6 of the bevel-gear wheel e9, meshing with gear-wheel e8, crank c", and hand-le ver e3, roller' E, and shaft ew, the whole operating as herein shown, and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
