Application filed August 24:, 1891. Serial No. d03,567. (N0 model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE SCHUBERT, a citizen of the United States, residing at Walnut, in the county of Bosque and State of Texas, have invented a new and useful Mechanism for Harvester-Reels, of which the following is a specification.

This invention relates to mechanism for harvester-reels by which the reel can be moved to any desired position and by which, also, to support the reel after it has been moved int the desired position.

In the drawings, Figure 1 is an elevation of the mechanism as seen from the rear of the machine. Fig. 2 is a view of the reel from the grain end of the machine. Fig. 3 is an enlarged longitudinal horizontal sectional view on line 1 1, Figs. 1 and 8. Fig. 4 is a side view of the frame or housing as seen from the under side with the locking-dog in position. Fig. 5 is an end view of same. Fig. 6 isa detail view of the locking-dog. Fig. 7 is the same as Fig. 4 with the gearing in position. Fig. 8 is an end View, looking grainward, with the chain removed. Figs. 9 and 10 are views of the clutches.

A designates the finger-bar, made in the ordinary Z form, secured with its stubble end to the bracket A, which is anchored on the axle A A designates the master-wheel, secured to its axle A by the pin A Said axle A is j ournaled with its stubble end in the upper end of the bracket A and with its grain end in the post A and is provided with a sprocketwheel A on its grain end, provided with a chain A, said Wheel A being located in the same plane with the sprocket-rim A and at the inner or stubble end of the cutting mechanism.

A is a collar secured to the axle A adjacent the bracket A to prevent any longitudinal movement of the axle A The post A is secured with its lower end to the finger-bar A a proper distance from the bracket A in a vertical position and of proper height. To its upper end is pivoted with its lower end the rack-bar f. The rack-bar f is pivoted to the upper edge of the grain-board D and on line with the pivot of rack-bar f. The rack-barf is pivoted to the outer side of the grain-board near its lower edge and front end, as seen in Fig. 2, and the rack-bar f is pivoted to the inner grain-board D on line with the pivot of the rack-bar f so that they may engage with the pinions J and J, respectively, in different planes. The inner grain-board D is secured to the post A and projects forward, and the grain-board D is secured to the grain end of the finger-bar A in any well-known manner and is provided with a stud B to receive the grain-Wheel B.

g is a brace pivoted with an eyebolt g to the bracket A and with its other end secured to the rack-bar f at the lower end of its perforations f and is to prevent any lateral movement of the rack-barf? 'i designates a frame or housing extending overthe gearing, formed, preferably, as shown in Figs. 3, 4, 5, and 7, with the bracket i and i journaled on the shaft h a proper distance apart and rigidly securedto the bar 11 Said bar t projects beyond the bracket 01 toward the reel a proper distance to receive the stud j to carry the anti-friction roller j.

i and i are inward projections of the brackets 2" and i forming guides for the pinions J and J or preventing any longitudinal movement of the pinions Jand J in the housing 1'. The opposite end of the bracket '5 is bent stubbleward and provided with a bar i, riveted thereto, to operate on the rear of the rack-bar f i is a bar journaled on the shaft h between the bracket 1" and the pinion J, with its lower end bent grainward and having a bar 2' riveted thereto to operate on the rear of the rack-bar f. The bars 1' and i are to hold the housing i and the bar i respectively, in a right-angle position to the rack-bars f and f respectively. The endz' of the bracket 2" is extended to nearly the same length as the'bar i and is to prevent the lower end of the bar i from bending stubbleward. Said bar i has an independent movement to that of the housing 71 on the shaft h, so that the bar 2' remains in a'right-angle position to the rack-bar f, while the housing'i remains in a right-angle position to the rack-bar f so that the rack-bars f and f respectively, can be engaged with the pinions J and J, respectively, in different planes. The bar 7' is bent as shown and secured to the bar 2' near the center of the housing 2'.

7' designates a dog formed as shown and pivoted to the bar 9' with the notch j 7 engaging with the periphery of the disk J 2 and with its wings or projectionsj and j engaging with the cogs of the pinions J and J. Said pinions J and J are clutch-pinions journaled on the shaft h and held in position by the housing 1' and with their teeth or cogs engaging the rack-bars f and f respectively. Their inward-projecting hubs t and t are notched to form clutches of any well-known form.

J is a disk rigidly secured to the shaft h in the housing 2', between the pinions J and J, and is provided with projections 25 to engage alternately with the notches of the pinions J and J, and its periphery is beveled to engage the notch f to operate the dog f. The shaft 72 extends through the housing 1', the reel-shaft K, and the housing i at the grain end of the reel, with its stubble end projecting and provided with an oblong perforation W. The shaft h is bifurcated and pivoted to the stubble end of shalt h by a pin extending through the perforation 71 and secured in the prongs h, thus forming a universal joint. The stubble end of the shaft h is journaled in the post 6. The perforation in the post e is made of sufficient size to allow the shaft h to operate in different planes.

h is a pin secured in the post 8 below the shaft 71, extending in the passage-Way of the crank 72. Said crank 77. is pivoted to the shaft h by a pin, with its perforation of sufficient size to allow the crank to be moved to an angle, as shown in dotted lines in Fig. 1, so as to clear the pin 71 when so desired. The post 6 is secured with its lower end to the bracket A, as shown in Fig. 1.

K designatesa hollow reel-shaft, encircling the shaft h and provided with right-angled flanges m and m on each end, in position to be operated on by the anti-friction roller j, as shown.

n is a bearing secured in the stubble end,

of the shaft K by the screws n. A similar bearing is secured in the grain end of the shaft K.

n is a bearing located near the center of the reel-shaft K and secured to said shaft K by the screws n, which is to prevent the shaft 71. from bending and rubbing on the sides of the reel-shaft K. Said reel-shaft K is journaled on the shaft h by the bearings just described.

K and K are reel-arms secured to the reelshaft K near each end by the bolt K K are the usual reel-slats, secured to the free ends of the arms K and K A designates a sprocket-rim secured to the arms K and K by the bolts 0 and 0 and ferrules 0 and 0 Said ferrules or pipes 0 and 0 rest with one end against the rim A' and with their other end against the strips 0 0 are strips on the opposite side of the arms K and K to support the nuts 0 The bolts 0 and 0 pass through the strips 0 and 0 The ferrules 0 and 0 are of proper length to project the sprocket-rim A far enough stubbleward to bring the chain on line with the sprocket-wheel A and adjacent the rack-bar f.

The housing 2' at the grain end of the reel is constructed and operated the same as the one just described, and thus need not be described.

The operation is as follows, viz: When the operator desires to elevate the reel, he moves the shaft h and h grainward, thus moving the disk J in the same direction, disengaging the projections t of the disk J from the pinion J and engaging it with the pinion J, and disengaging the dog from the pinion J and engaging it with the pinion J, as shown in dotted lines in Fig. 7. The rack-barf being secured in position by the brace g and the pinion J being in engagement with the rack-bar f and held in position in the housing 2', it will prevent the housing 1; from having any grainward or stubbleward movement, and the reelshaft K being held in position by the anti-friction roller j, operating on the rear of the flange m, and a similar roller operating on the rear of the flange m will also hold the housing 71 in position. Thus it will be seen that both ends of the reel are operated simultaneously. After the shaft his thus shifted grainward it is rotated in the direction as shown by arrow in Fig. 8 by means of the shaft h and crank 77. until the reel iselevated to the desired position. When it is desired to pitch the reel forward, the shaft h is drawn stubbleward until the disk J is in engagement with the pinion J, when the dog also looks the pinion J and unlocks the pinion J, when the shaft h is again rotated in the direction as shown by arrow in Fig. 8 until the reel is in the desired position. When it is desired to lower the reel or draw it toward the rear, the rotation of the shaft 71. is reversed. The dog 7' is so constructed as to engage with the pinions J and J just before the clutch or projections 25 disengage the pinions. When the disk J 2 is near the center between the pinions J and J ,the dogj is in engagement with the cogs of both pinions J and J, thus locking both pinions in place. After the reel has been moved in the desired position the disk J 2 may be drawn to near the center between the pinions J and J, or it can be left in engagement with either pinion J or J, as the crank 77. will come against the pin h and prevent the shaft from any rotation.

A is the reelchain, extending over the sprocket-Wheel A and over the sprocket-rim A to operate the reel.
