Specification of Letters Patent.

Patented Ail- 10, 1915.

Appli'catimi filed January 13,1-91'5; Serial no. 1 ,992".

To of whom it may concern:

Be it known thatI, BOUKA DE Born, a itizen of the United States, and a resident of Corsica, in the" county of Douglas and State of South Dakota, have inventeda new and Improved (ham-Spout 'Aldjuste'r, of which the following is a full, clear, and exact description.

'l ris invention relates to improvements in adjusting means for grain chutes or spouts, and has for an object to provide an iinproved- 'const'ruction adapted to be used in any place, especially on a thresher whereby the dischargin chute may be moved to any desired position and locked in said position;

Another object in view is to provide an adjusting means for a grain ch'utewhich may be swung around a suitable pivot and locked at any point within its movement.

A- furth'er object of the invention is to provide a locking device for locking a grain chute in any osition and means co-aeting therewith for raising and lowering the discharge end of the chute. i g

In the accompanying drawings-Figure 1 i is air enlarged detailed fragmentary side view of part of an elevator grain chute and mechanism embodying the invention; Fig. 2 is an enlarged detailed fragmentary side view of means for raising and lowering the discharge end'of the chute; Fig. 3 is a section through Fig. 2 approximately on line 3-3; Fig. isa' sectional view through Fig. 2' on line Fig. 5' is an enlarged side view of the locking mechanism and associated parts embodying certain features of the invention; Fig. 6 is a top' plan View of the struct'i'ire shown in Fig. 5; Fig. 7 is" fragmentary sectional view on line 77 of Fig. 5.

Referring to the accompanying drawings by numerals, 1 indicates part of a threshing machine and 2 an elevator of any desired kind. Pivotally connected near the top of the elevator 2 is a grainspout or chute 3 of substantially any desired kind, which spout or chute is provided with a valve or shutoff 4!. near the lower end. It will be evident that the elevator and chute could be associated with other devices in addition to a threshing machine, as for instance an ordi nary grain bin. However, when using a threshing machine it is designed to have the same continuously operate and therefore continuously discharge grain therefrom. In order that the continuously discharged grain may be loaded into diilerent sacks; or other suitable receptacles in small quantities, it is necessary to move the chute or spout 3 on its pivotal liie'aring 5' which may be of any desired kind; Asthe discharge will not instantly filt the sack or bag it is necessary to hold the spoutor chute 3 stationary for an appreciable time in order that the sack or receptacle may be filled. To obviate the necessity of'empl oying a person continually for holding the spout in proper position, means have been provided for locking the spout quickly in any desired position. The gate or valve 4 is used for temporarily shutting oi? the grain while the chute is being moved from one position to another.

As shown in Figs. 1, 5 and 6, a semi-circul ar rack o is provided which is bolted or otherwise rigidly secured to the elevator 2,

and which is provided with a flange 7 having spaced notches 8 which form the rack and" which are adapted to receive the" legs 9 and 10 of a pivotally mounted frame 11. The pivotally mounted frame 11 is pivotally mounted on the'bra cl'ret 1 2 which is clamped by a suitable bolt to the bracing beam 13.

The bracing beam 13 is provided with an eyelet 14 interlocking with the eyelet 15, which eyelet is pivotally connected with a bracket 16 riveted or otherwise rigidly secured to the elevator 2. The frame 11 is provided'with an upwardly extending arm 17 to which one end of spring 18 is connected, the opposite end of spring 18 being con-. nected with a stop or eyelet 19 secured to the beam 15. Spring 18 is a retractile spring and tends to continually hold the legs 9 and IOin engagement with the. notches 8 of the rack (i and thereby prevent a swinging of the bracing beam 15 and th'e chute 3* with which it is connected. The outer end of beanr 15- is provided with a tongue 20 (Fig. 3 and'a pairof bearingsides 21 and 22'which rest upon-the lower surface of the flanges 23' and 2 k of'tlie guide 25, while the tongue 20 fitsd nto the g-iioove-26'oftheguide 25. The outer end of the beam 13 is provided with a lock or eyelet 27 .u hich"ieceivesthe cable 28,

' said cable 28'passing over a pulley 29 and rying tongue 20 is raised to the desired extent. A reverse movement of the various parts will of course allow a lowering of the end of the chute or spout 3. Usually the spout or chute 3 is adjusted to a certain height before the grain is allowed to be discharged therefrom and is left in that adjustment for an indefinite time while the chute is swung back and forth as occasion may demand.

In order to allow a person near the lower end of the chute or spout 3 to quickly move the spout a pivotally mounted arm or crank 31 is arranged on the spout 3 to which isconnected a cable 32. Cable 32 passes over pulley 38 mounted on the outer end of beam 15 and has the inner end connected with the lower part of frame 11 so that when the crank or lever 31 is moved upwardly or away from the spout 3 frame 11 will be moved pivotally out of engagement with rack 6, whereupon the spout or chute 3 may be moved to the desired position after which the crank 31 is released and frame 11 will automatically engage the rack 6 under the action of spring 18. The cable 32 may be of any desired structure but usually adjacent the frame ll, the same being formed as a chain so that any of the links may be caught or hooked over the hooked member arranged at the lower endof the frame 11, whereby the slack in the cable may be taken up easily.

In operation the parts are adjusted, for instance, substantially as shown in Fig. 1,

and when it is desired to move the chute to one side so as to discharge to another receptacle crank or lever 31 is raised and frame 11 moved out of engagement with rack 6. The chute or spout is then manually swung to one side after which crank 31 is released which will allow spring 18, to cause legs 9 and 10 of frame 11 to engage rack 6. This will lock the chute against any further swinging movement. If for any reason it is desired to raise or lower the chute cable 28 is actuated so as to raise or lower the outer end of bracing beam 15.

What I claim is- 1. In a device of the character described, the combination with a pivotally mounted grain chute, of a guiding track arranged thereon, said track being formed with a groove, a pivotally mounted bracing beam having a nose fitting into said groove, means for supporting the outer end of said beam, said means being used to raise the outer end of said beam for adjusting the height of the outer end of the chute, and a locking member connected with said beam and with the chute for locking the beam and chute against a horizontal swinging movement.

2. In a device of the character described, the combination with a chute, of a pivotally mounted bracing beam for supporting the outer end of the chute, means for locking said bracing beam and the chute in any desired position and against horizontal swinging movement, said means including a stationary rack, a member acting as a catch pivotally mounted on the beam, and adapted to engage said rack, and an operating member extending to a position adjacent the lower end of the chute.

3. In a device of the character described, the combination with a swinging chute, of means for locking the same in any adjusted position, said means comprising a bracing bar, a rack formed with a plurality of notches, a swinging catch member pivotally mounted on said bracing bar and formed with a pair of arms adapted to fit into said notches when the same is in a locked position, a spring acting on said catch member for causing the same to normally engage said rack, and manually operated means extending to a position near the lower end of said chute for releasing said catch member temporarily.

I. In a device of the character described, the combination with a swinging chute, of means for locking the chute in any adjusted position, said means comprising a bar for supporting the lower end of the chute, a pivotally mounted catch arranged on said bar, a spring for urging said catch in one direction, a stationary rack adapted to be engaged by said catch whereby the catch and the bar cannot move, and a cable extending from .said catch to a point near the lower end of said chute, said cable being adapted to be manually operated for releasing said catch when it is desired to swing said chute.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 1
