GRAIN-ELVATING DEVICE.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed December 27, 1904. Serial No. 238,45 5.

T0 a/ZZ whom it may concern:

Be it known that I, NELs H. NELSON, a citizen of the United States, residing at Pennock, in the county of Kandiyohi and State of Minnesota, have invented certain new and useful Improvements in Grain-Elevating Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its especial object to provide an improved elevating' device for use on farms and elsewhere to elevate grain and deliver` the same into storage bins or silos; and to such ends it consists of the novel devices and combination of devices hereinafter described, and del-ined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a view principally in side elevation, but with some parts sectioned and some parts broken away, showing my improved elevating device. Fig. 2 is a transverse section taken approximately on the line rc2 :r2 of Fig. 1. Fig. 3 is a front elevation of the device, some parts being removed; and Fig. et is a horizontal section taken approximately on the line af* af* of Fig". 1.

The numeral 1 indicates a heavy supporting-base, as shown, in the form of a frame constructed of timbers, and provided at its forward end with a transverse rest-beam 2 and at its rear end with an axle 3, equipped with detachable wheels 4. The numeral 5 indicates a rear-end extension of the frame 1.

Pivoted at 6 to the forward end of the frame 1 is a heavy upright 7, having on its opposite side faces longitudinally-extended guidelr'ails 8. l/Vhen the device is to be moved, the upright 7 may be turned downward in a horizontal position; but when it is in an operative position it stands substantially vertical and is held in such position by a heavy brace-bar 9, detachably secured thereto at 10 at its upper end and detachably secured at its lower end to the frame extension 5 by pins or bolts. WVhen the device is located for work, the wheels 4 will usually be removed, so that the base-frame may rest flat upon the ground.

The numeral 11 indicates a loose block which is temporarily placed under the rest-beam 2.

A truck runs vertically up and down the upright 7, and a large grain bucket or hopper 12 is rigidly but detachably secured to the body 13 of said truck, as shown, by means of short nutted bolts 141. The truck-body 13 is provided with U-shaped brackets 15, that embrace the sides of the upright 7 and are provided with truck-wheels 16, that run in the channels formed between the cooperating pairs of rails 8.

At its lower-most portion the hopper 12 is provided with a discharge-orifice 17, which is normally closed by a vertically-movable gate 18, mounted in guides 19 on the rear face of the hopper and pivotally connected to a lever 20, which is pivoted to said hopper at 21. A spring 22, attached to said lever and to said hopper, normally holds the gate 18 closed. The discharge-orifice 17 is provided with an extended discharge-spout 17. To the free end of the lever 2O is attached a depending trip connection, preferably in the form of a rope 23, which is long enough to always approximately reach the ground.

In practice the upright 7 will often be made more than twenty feet in height. On its extreme upper end it is provided with a bearing-bracket 21, on which is journaleda pair of guiding-sheaves 25, one located in front and the other at the rear of the upright. Another guide-sheave 26 is journaled in a bearing-head 27, which is secured to the upper portion of the truck-body 13. A hoisting cable or rope 28 is attached at onc end to the forward end of the bracket 241, is passed under the sheave 26, over the two sheaves 25, and, as shown, under a guide sheave 29, mounted on the lower portion of the upright 7. The hopper 12 may be raised by drawing on the lower end of the cable 28, and this may be done either by hand, by an engine-driven drum, (not shown,) or by one or more horses hitched to said cable.

Vhen the hopper 12 is raised, as shown in Fig. 1, one prong' of the upper truck-yoke 15 is engaged by the hooked end of a weighted latch-lever 30, which, as shown, is pivoted to a bracket 31, rigidly but adjustably secured to the upper end of the standard 7. By this latch 30 the hopper is held or locked in an elevated position, and when it is thus held its discharge-spout 17 is alined with a telescopically-extensible section 32 of a discharge-spout 33. This discharge-spout at its upper end is preferably formed with pivotally-connected sections 33 and 33", which give such flexibility to the spout that its free end may be moved over a considerable area, thereby permitting the grain to be directed to the de- IOO IIO

`telescoped over the dischargefspout 117".

sired point of discharge.

34, which bracket is adapted to be secured in different vertical positions ontheiiprightby means of lag-screws 34: or other suitable devices. As shown, one prong ofthe hracket'34kis i rigidly secured to the spout-section 33". Tothe other prong of said bracket is pivoted a bell-i .crank 35, the lower arrn of whichis connectspring 38, connected to the spout-sections'32 and 33, Vnormallyl holds the'former drawn into thelatter, as shown in Fig. 1.

rlhe operation of the device vis probably evi-1 dent,but may be lbriefly stated as followsz The hopper 212, beingloaded-withgrain, is elev vated 'by drawing on the cable 28, as already described, andas it reaches its extreme upperv position the upper truck-yoke l'engages the .cam-shaped end of the :weighted latch-:lever 30, passes the said cam-end, and is then en-E gaged and'locked by said lever. Then'by.piill Iing on the rope 37 the spout-section 32 listelescoped over the spout 1.7?, and then by pull-f ing on the .trip-rope 23 -the valve '18 is opened and the contents of the hopper are permittedE to run therefrom out through the discharge` Afterthe 'hopper has been emptied by drawing on the trip-rope 39, which is atspout.

tached to the freeend of the weightedilatc'hlever 30 and extends tothe ground, the hopperis released and may then be lowered at will.

The hopper may be detached from'the truck` andanother 'form of carrier may be applied thereto-such, [for instance, `as that shown in a companion application led by me of even -date herewith, entitled Hay-elevator.

.ters Patent ofthe United States,`is as follows:

1. The combination with an upright, of a lcarrier movable vertically thereon, and having .a valved discharge-opening, a connection for operating the valve of said discharge-open1ng As shown,'the upper end of the spout issupported .bya bracket 'from'the lower portion of said upright, means foriraising-.and lowering k-said carrier on said upright, and a latch for securing said carrier y fin anelevated position on said upright, said latch having atrip connection extending to the lowerportionlof said upright, substantially as described.

2. The combination with an upright, of a delivery-spout supported at its upper end from the upper portion of saidupright, and having an extensible .receiving-section, `connections for distending said receiving-section from the lower portion of said=upright, ahopperfhaving wheels working in guideways on said upright, means formoving saidhopper vertically on said upright, avalved discharge-opening in said hopper adaptedto register with said extensible Vspout-section, a connection "for operating the valve of said discharge-opening fromthe lower portion of said upright, a'latch foriholding said hopperin a raised position,

and atrip connectionfor saidilatch extending to .the'lower portion of said upright, substantially as described;

118 and'to 'said hopper andhavingatrip'connection22,a sheave and cablehoisting device for raising saidhopper on said `upright, a latch-lever 30 operative on a part movable withsaidtruc'k andhopper, to hold the same 'inan elevated position, a trip connection 39 applied to :said latch -t'lever 30, a deliveryspout supported from lthe .upper portion of said upright, and'having a distensible section 32 adapted to register with the hopper discharge-opening 17 when said hopper is raised, a spring normally retracting said spout-section32, azlever connected 4to said yspout-section, and a 'trip connection attached to'said lever, substantially as described.
