Be it. known that. I, Unom'no ll. ()DELL, formerly oi Minneapolis, Minnesota, hutv now of Dayton, Mont gomery county, Ohio, have invented certain new and useful improvements in Roller-Mills, oi which the following is a specification.

My invention relates to improvements in roller-mills for crushing or grinding grain, middliuga, and other material, and has for its, object to provide novel and t-llicicnt means fort K indicates another crank, keyed upon the adjusting the outer crushing or grinding rolls through-shalt J, inside ofthe link I and oppoto or from the inner oues, and simultaneously l site the crank II- with such adjustment, operating the hopper- The letters k'k'iudicaie crank-rods pivoted .hlt indicate two horizoutal'shaits supported 4 in bearings c c in the housings H and on the frame 1), the inner ends of which shafts It h are t'orked and engage the segmental camelots i in the links 1 by a bolt which passes through the forks h and through the said slots. .The links Iarekeycd upon a thronglt-shaft,J, to which latter is also keyed a. crank, In.

These objects 1 attain by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents an end elevation of ai'onr-roll crushing or grinding mill embodying my invention. Fig. .3 l't']tt".-t-tti-' 'l aideele vatiott of the same on the line L .5 at Fig. l, the pulleys to the right oi this line heing omitted in order to more clearly illustrate the parts. Fig. 3 represents a detail plan view, partly in tiectlotnui one of the tighteniug-pullcvs and its supportingframe. Fig. 4 is a diagram showing the arrangement of tho t'ant-upeeded crushing ongrludingrulln and bolt-coonactions, and Fig.5 a a similar view showing the opposite side oi the machine.

i hopper are, fixedtlm niniouelflwhloh mesh into the racks M odours m, which entry at their lower ends the gates or slideam. {.ilhes' slides, when in a closed position, rest upon feed-rollers m, oi the. usual construction, and serve to close up the spout or l'ced-elntnnels which conduct the grain from the hopper to tho feed-rollers, from which the grain its discharged hetwecn the crushing-rolls.

The crushing or grinding rolls (1 (I' are mounted on through-shafts having hearings at each end similar to those shown in Fig. 2, and the shall. .i passes through to the opposite side of the machine, and has duplicate links i, connecting-rods, and cranks connected with forked shafts and to pinions, in the same manner as shown in Fig.2.

ass-r AvAiLABLE COPY the met-spa .cd rolls, and a similar pulley nt'the same size is mounted on the other shaft. At the opposite end of the machine two pnl leys, 0, of a suiticicntly large size to obtain the requisite slow speed, are mounted on the shafts of the slow-encoded rolls. These two sets of pulleys, O O, are driven by separate driving-belts from a main shaft.

P P indicate the belts.

It indicates the shafts on which the tight ening-pnlleysparejonrnaled,and it segmental gears attached to the ends of levers Q by means of bolts r r.

Sindicates pinions keyed to thethronghshafts, which is journulediu oron thet'rameD. T indicates a hand wheel or lever keyed to the throaghshalt S, which shaft passes across the frame of the machine trtmsveranly from end to end, as shown in Fig. 1. The two tightening-pulleys 1) can be adjusted to or from the belts .l l" by rotating the shalt S through the instrnmentality ot the rotating handwheel T, which has the eti'ect of swinging the forked levers Q on their pivot-bolts q,(see Fig. 3,) and either raising or lowering the forked ends of the levers which carry the shafts R of the tightrsiingmulleys, according by the hand wheel or lever T. By this means the machine. may be instantly stopped or start by mesa; of the leveroperating the ugntener'pntleys.

Fig. 7 shows the mode of belting from the 'naiirl'rame pulley O" to the pulleys 0 0 of the l'astspceded rolls, with the tightening-pulleys in position to drive the same. Fig. 3 is a similar plan of driving the slow-speeded rolls, the only ditl'ereucc being in the size of the pnllcys toobtain the two ditl'erentspeeds at; which the crushing or grinding rolls are driven.

Instead of arranging the belts 1 l? to run one over the t'nst-speedcd rolls, the. belts may he each made to drive one fast and one slower spcedcd roll by changing the size of the pol ieys, so that each set of crushing-rollers is driven by bolts at the opposite ends of the nun-.hinc, as the tightening-pulley P will permiteitherbeltto run over pulleys O 0' O".

This mannel'trf throws-hing o1- grinding rolls in order to drive them with varying or difl'erential speed is not, however, herein claimed, and is only here illustrated to givca clear conception of the entire structure.

\Vhat I claim is-- 1. In-a. roller-mill, the combination of the hopper-gate mechanism on both sides of the machinewith a through -shaft, lever mechanism eohnecting the parts to operate the gates simultaneously, and a single hand-lever, subatantially as and for tllOIltliliOSG described. ,2 In a roller-mill, the combination, with the ad ustabl'e rolls and journals, of transverse shafts h, a through-shaft, J, link mechanism connecting the said we, and a sanete'imwi lever, K, connected with the through-shaft, for simultaneously adjusting both sets of rolls by a single lever movement, substantially as 1 described.

3. Ian roller-mill, the combination of two i'scts ot' crushingor grindingrolls, belt and pulley driving devices, the tightenerpniicys, adjustable fr amcs therefor, and mechanism for simultaneously raisingand lowering the frames ahd tightener-pullc vs to stop and start. the ma chine, substantially as described.

4. In aroller-mill, thceombination, with the adjustablecrushing-rolls and thegates or slides which control the passage of grain from the hopper, ot'a single through-shaft, J, a single ,himd-lcver, K, and mechanism connecting, the crushing-rolls and the gates or slideswith the lthrough-sbat't and hand-lever, substantially as described', whereb v a. single movement ot the I lever simultaneouslyadjusts the rolls and the to thodirection in hick the shaft S is rotated gates 0! slides, as set forth 5.
