ENDLESS CARRIER FOR HARVESTERS.
SPECIFICATION forming part of Letters Patent No. 293,383, dated February 12, 1884'.
I Application filed October 3, 1883. (\'0 model.)
To all whom it may concern.-
Be it known that I, JOHNSTON TAGNER, a citizen of the United States, residingat Moorhead, in the county of Clay and State of Mia nesota, have invented certain new and useful Improvements in Endless Carriers for Han vesters and other Machines, of which the following is'a specification, reference being had therein to the accompanying drawings.
My invention relates to that class of endless carriers consisting of an endless apron supported 011 rollers or drums arranged at opp'osite ends of a frame, which may be placed horizontally or in an inclined positidn,accordingly as it may be desirable to transport the material to be conveyed horizontally or to elevate the same; and the object of my invention L is to provide simple and e'fficient means for properly tightening the carrier-apron by simultaneously adjusting both of the journalbearings of one of the supporting drums or rollers for the said carrier-apron, thus quickly and easily effecting theadjustment, and at the same time keeping therollers parallel to each other.
In the accompanying drawings, Figure l is a plan view, partly in section of an endless carrier embodying my invention. Fig. 2 is a sectional viewof the same on the line 2 2,Fig. 1; and Fig. 3 is a side view.
A A are the stationary or fixed side pieces of the carrier-frame, in which one of the supporting druinsor rollers B is journaled, the power for moving the carrier-apron 0 being preferably applied to the shaft of the said roller by means of a gear or sprocket wheel or a sheave secured to said shaft. A,are recessed on their inner faces for the reception of plates D,which latter are provided at their outer ends with blocks (1, having bearings for the adjustable supporting drum or roller 13 for the carrier-apron. The plates D are preferablyof metal,and the bearing-blocks d may be formed integral therewith orsec'ured thereto in any suitable manner. The plates D are each provided with inner slots, (1, and outer slots-d one side of each of the outer slots being formed into teeth, constituting a rack,- (l As the slots .d and d are both inc'losed or, in other words, are bounded on their opposite sides by the material compos- The side pieces,
I. ing the plates Dsaid slots are adapted to serve as guideways, as will presentlybe indicated. Arranged within the inner slots, d,of
the plates D are guiding pins or bolts a, en-m tering the side pieces, A, of the carrier-frame, said pins or bolts being preferably screwthreaded, so that they will be securely held in said side pieces. These pins or bolts a, one or more of which may be placed in each of the slots (7-, serve, in connection with said slots, to assist in guiding the plates D on the side pieces, A, thus preserving the alignment of said plates with said side,pieces as the former are moved outward in tightening the carrier apron. V
F is the tightening-shaft for the endless carrier-apron, said shaft being journaled in the side pieces, A. Formed integral with or secured to the shaft F are two pinions, f, arranged within the outer inclosed slots, d, of the plates D, said pinions being preferably of such size that they can just barely turn freely within saidslots without binding, thereby assistingin preserving the alignment of the plates D with the side pieces, A. One end of the shaft F projects through one of the side pieces, A, and a ratchet-wheel, f, is secured to said shaft outside of and adjacent to the side piece, and to the latter a pawl, f, is pivoted in such position as to engage with said ratchet-wheel and prevent its backward'rotation after the shaft F has been adjusted, thus holding the plates D and the adjust-able supporting drum or roller B securelyin position. The project? ing end of the shaft F-is squared for the reception of a key or wrench, G, by means of which said shaft may be turned when desired. It will be understood that the pinions f on the shaft F are both just alike, as are also the racks d on the plates D, so that when the shaft F is turned both of the plates D will be moved an equal distance, thus simultaneously adjusting both of the bearings for the adjustable supporting-roller B, which latter, whatever its position of adjustment, will always be parallel with the roller B. Thus the carrier-apron G will at all times run evenly on the said rollers, and said apron may be quickly and easily tightened or slackened as circumstances may require.
I am aware that it is not new to adjust both ICQ of the bearings of one of the supporting-rollers of an endless carrier-apron simultaneously, and I do not, therefore, Wish to be understood as broadly claiming means for effecting this result; but i What I do claim, and desire to secure by Letters Patent, is
1. In an endless carrier, the combination, with the side pieces of the frame, of adrum or roller journaled in said side pieces, two adjustable plates, each provided with inner and outer inclosed slots, the outer slots each having a rack on one side, pins .or bolts fixed to said side pieces and arranged in the said inner slots, a drum or roller journaled in the outer ends of said plates, a shaft journaled in said side pieces, two pinions fixed to said shaft and arranged in said outer slots in engagement with racks, and means for securing said plates in position after adjustment, substantially as hereinbefore set forth.
2. The-combination, with the recessed side v JOHNSTON WAGNER.
