IMPROVEMENT IN DEVICE ER CHANGING FEED.

TO ALL WHOM IT MAY GONCERN:
Be it known that I, R, NELSON, of Mexico, in the county of Oswego,`and State of New York, have invented a new and improved DeviceforOhanging Feed; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ofthis specification, in which-- Figure 1 represents a plan or top view of my improved feed-changing device.
Figure 2 is aninverted plan view of the same.
Figure-3 is a. vertical longitudinal section ofthe same, talrenon the plane of the line :e a, hg. 1.
Figure 4 is a vertical transverseisection ofthe same, taken on the plane of th'e line y y, fig. I.
Similar letters-of reference indicate corresponding parts.
This invention relates to a new' device for changing the feed of saw-mills or other suitable machines, and consists in the general combination ofthe devices by which the desired result is obtained; also in a new manner of arranging the gear-wheels, and in a new method of moving the shifting-gear, and of throwing it in gear with the driving and driven gears. I
A, in the drawing, represents a frame xof suitable construction, made of suitable material and of suitable dimensions. In the frame A are the bearings for two parallel shafts, B and C. The shaft B is the dri-vingshaft, receiving motion from suitable mechanism, while the shaft C is to receive its motion from B. Upon each shaft B and C are mounted square-faced gear-wheels, of various diameters, the diameters'of those ou thc'shaft B gradually decreasing towardsone end of the shaft, Vwhile those on the shaft C gradually increase towards the same direction,l so that the larger wheels, a, on-the shaft B, are opposite the smaller wheels, on C, and 'uz'ee versa. It will be noticed that the space yleft between the edges of the opposite wheels, a b, has a curved form. This is produced by arranging the diameterscf the wheels so that a regular difference of motion is produced between theirst and last gears of the two shafts. Thus, for example, if the shaft B makes one hundred revolutions per minute, its largest wheel will cause the shaft C to make two hundred revolutions in the same time. The next largest wheel will cause one hundred and forty revolutions of the shaft C, the last eighty, and. thus the same difference of sixty revolutions is produced between every two' pair of wheelsfa 6. If the wheels are` thus arranged, a line drawn through the faces of any set will be curved as shown, while, if they are arranged without regard to a regular difference of motion, the lines will be either straight or irregular.
` The other parts of this machine may he connectedwith gears arranged in the 'above-described manner or otherwise, and I do not confine them to anyparticular arrangement of gears. Under or over the shaft B C is arranged a sliding frame, D, which moves between suitable guides in a frame, E, and in which a shaft, F, which is parallel with'the shaftsB-and C, has its` hearings.- The frame is pivoted at one, end to the frame A, while its other end is connected withsuitable levers, c c, by means of which the free end can be raised o1' lowered at will. The shaft F carries a gear-wheel, d, as is clearly shownin fig. 4. Thesliding fname D is, by means of jointed hars e e,-connected with a rock-shaft, G, which can he turned by means of a bar,f, `that is pivoted or' jointed to a crank, g, projecting from the said Vrock-shaft, as fhown'in lig. 3. As the rock-shaft G is turned, the frame Dis moved longitudinallyin the frame E, the shaft F always remaining parallel with the shafts B C;
thereby the wheel ol can be brought in line with any desired opposite pair of wheels, a l?, and when, then, the
frame E is turned, such pair of wheels a I) may he connected by means of the wheel el, and the desired number of revolutionsv may be imparted to theshaft C. Itisof importance that the wheel d should first come in gear with the' driving-shaft, and then with the shaft to be driven. For this purpose the pivoting-pin t, on which the frame E turns, is nearer to the shaft B than to C, and when thus the frame E is swung towards the shafts B C, the wheel cl will first come against thewhecl a, and when it is actually in gear with the same, it will also come in gear with the wheel Z. The so-ca'lled dead-gear is thus perfectly avoided. The frame D is, when a curved line is producedby the edges ofthe gears a I), connected by a pivoted bar, z', with the frame E, so that it will,
when drawn by the action of the barf, describe the required curve around the pivoting-ping' of the har ,as is.
indicated in fig. 2.
I claim as new, and desire to secure by Letters Patent- 1. So arranging the gear-wheels a b on two parallel shafts, B C, which are to be connected forchanging vthe feed of certain mechanism, thnt the line drawn over the faces of the wheels on eithe theft will he a curved line, as Set forth. v
2. :Hingingthe swinging frame E, iu which the shifting-gear d is held1 so `that the shifting-gear will first cme in geamwith the driving-shaft, and then with the shaft theti's to b e driven, Aas set forth.
v 3.l The sliding frame D, in which the shaift F, that carries the shifting-gent d Ihas; its bearings, when connectedgbynxeanspf `i'ointed. bars e, with the rock-shaft lG,hubs;tctntiz'illy as and for the purpose herein shown qnd described.
4. 'The arrangement and combination of the shafts B C, c-arry-ng the gear-wheels a aendbbfrespectively,
V-Yith the Wheel cl on the shaft F, sliding frame D, hinged frame E, leyeis cc, bars e e, and rock-shaft Gr, all made amloperatingl substantially as herein shown-,and described. l
