Application filed May 4, 1906. Serial No. 315,253-
To (LZZ whom it may concern:
Be it known that I, FREEMAN R. WILLSON, Jr. a citizen of the United States, residing at Worthington, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Conveyers, of which the following is a specification, reference being had therein to the'accompanying drawings.
. in driving mechanism for endless-conveyer systems. I
It pertains particularly to means for increasing the area of contact over which power is applied to an endless conveyer in such manner that the conveyer will be satisfactorily driven irrespective .of the load which it. throws on the driving mechanism and slippage between the carrying element of the conveyer and the driving mechanism will be prevented. The objects of the invention will be manifest from the description of a conveyer system embodying my improvements which I have herein employed for the purposes of illustration. i
Figure 1 is a side elevation of a mechanism embodying my improvement. Fig. 12 is a plan view of the same. Fig. 3 is a plan view showing a slight modification in'the driving mechanism. Fig. 4 is a side view of the same. 1 i
In the drawings, 1 indicates as an entirety a suitable framework for an endless conveyer.
Of this framework, 2 and 3represent lon itudinallyearranged beams upon which t e conveyer. guiding and driving mechanisms are mounted. J
4 indicates an endless belt for the system. At one end it is carried around or deflected and guided by a pulley or drum 5, mounted on a transversely-arranged shaft 6, which at either end is mounted in bearing-boxes 7 7, fitted in longitudinally-arranged guides 8 and adjustable therein by means of threaded rods 9 9, suitably secured to the bearingboxes and operable in the well-known manner to adjust the said boxes in order to take up slack and regulate the tension on the belt 4. i
'10 is a pulley or drum arranged at the opposite end ofthe conveyer system from the idle pulley or drum 5 and rigidly secured to a This invention relates to an improvement drive-shaft 11, mounted in suitable stationary bearings 12 12 carried by the frame.
13 is a belt-wheel rigidly secured to one end of the shaft 11, and 14 is a belt for driving said wheel, which may be connected with any suitablesource of power. (Not shown.)
15 is a pulley or drum ri idly secured to a shaft 16, arranged paralle to the shaft 11 and suitably mounted at either end in bearings 17 17 on the framework.
18 is a pulley-or drum ri idly secured to a shaft 19, arranged paralle to the shaft 16 and in the same horizontal plane therewith,
22 is a gear-wheel similar in size and numshaft 19, similar in size and number of teeth to the gear-wheels 21 and-22 and arranged to rotate it, and consequently the drum 10, and the gearing between the drum or pulleys 10, 15, and 18 is such'as to cause all of the pulleys to rotate at the same peripheral speed and in the direction indicated by the arrows in: Fig. 1'.
The belt 4 is carried around the pulley 10, then up over the pulley 15, then down around the pulley 18, and then up over an idle pulley or guide-wheel- 24, carried by a shaft 25, arranged parallel to the shaft 19 and suitably mounted in bearings 26 26 on the frame. This pulley 24 serves to cause the belt 4 to contact with substantially one hundred and eighty degrees of the periphery of the immev.diately-adiacent driving-pulley 18.
to the pulley 24 and sii'nilarly mounted, ex-- cept that it is arranged at the opposite end of the conveyer system therefrom and ,relatively near to the pulley 5..
pulleys of the same diameter, drivin them ing a driving mechanism for endless conveyerber of teeth to gear-wheel 21, with which it is arranged to mesh and by which 1t 18 driven. 23 1s a gear-wheel rigidly secured tothe it being suitably mounted in bearings 20 20, I
mesh with and to be driven by the latter.
Power is applied to the belt-wheel 13 so as to p 27 is an idle pulley or drum similar in size IOO ' It will be seen that by employing drivingat the same peripheral speed, and e ecting the contact ofthe belttherewith in the manv ner shown that I have succeeded in constructeasily assembled.
belts which will transmit power thereto over a large surface of the belt and'will also tend to revent the sli ping of the belt relative to t e drivingmec anism where heavy loads are encountered.
I have found 'my invention particularly well ada ted for use in driving endless conveyers 0 great length where extremely heavy 3 loads must be dealt with and where the contact of the belt with a single pulley is not sufficient to provide a satisfactory drive.
In my preferred construction the drivingpulleys .are all arranged beneath the upper run of the conveyer-belt and substantially in the same horizontal plane, so as to allow a very simple framework structure and to insure that the parts can be readily and In the modified construction shown in Figs. 3 and4 instead of employing a spur-geared drive between the beltdrwing pulleys I have substituted a chain drive.
28, 29, and 30 are sprocket-wheels of equal pitch diameter and number of teethrigldly secured to the shafts 11. 16, and 19, respectively.
31 is a chain suitably connecting these sprockets 'so as to drive the pulleys 15 and 18 in the direction indicated by the arrows in Fig. 4.
What I claim is e 1. In a conveyer, the combination with an endless belt,.of a driving mechanism therefor comprising a-plurality of driving-pulleys arranged substantially in line with each other and geared together to have their peripheries travel at the same speed, the'said belt being carried around the endmost pulley and then alternately over and under the remaining pulleys so as to contact with. opposite sections of adjacent pulleys, and means for driving the said pulleys.
2. In a conveyer, the combination with an endless belt, of a driving mechanism therefor comprising a series of driving-pulleys of um form diameter arranged substantially in line with each other and geared together to have their peripheries travel at the same speed, the said belt being carried around the endmost pulley of the series and then alternately over and under the remaining pulleys of the I series so as to contact with opposite sections of adjacent pulleys, and means for driving the said pulleys.
3. In a conveyer, the combination with an endless belt, of a driving mechanism therefor comprising a series of driving-pulle s of uniform diameter arranged substantia ly in line with each other and flexibly gearedtogether to have their eri heries travel at the same speed, the said be t being carried around the endmost pulley of the series and then alternately over and under the remaining pulleys of the series so as to contact with opposite sections of adjacent pulleys, and means for driving said pulleys.
endless belt, of a driving mechanism therefor comprising a series of driving-pulleys arranged substantially in line with each other beneath the upper run ofsaid belt and geared together to have their eripheries travel at the same speed, an i le guide-pulley ar ranged adjacent to the innermost pulley of said series, the said belt being carried around the endmost driving-pulley of said series, then alternatel over and under the remaining driving-pul eys of the series so as to contact with opposite sections of adjacent driving-pulleys and then over the said idle ulley so as to cause the belt to contact with substantially one hundred andeighty degrees of the innermost drivingulley, and means for driving said driving-p11 le S.
In testimony whereof I afiix my signature in presence of two witnesses.
