To all whorn it may concern: v

Be it known that Wefllr iLLniM States, andresidents of Mechanicsburg, .in

the county of Cumberland and Statec'f- Pennsylvania, haveinvented a new and I mprove Sheaf Hoist and. Chute, of which the followingisla full,-elear, .and exa-et (le-- Scrip'tion. 1 Our invention relates to an4 more particularly intended for elevatlngl sheaves of unthreshed grain to barns or other outbuildings, or onto stacks or niows. The invention lcontemplates alsoa chute Ae0 ar-A ranged as to distribute lthe sheaves over the mow orrooni: l' I Y It is a desig'fn'of ourjin'vention to improve in various partcula-is apparatus of the character indicated, to the end tliat ^'elli.

ciency may be promoted, as well as siinlplicity of construction, `adjustment and con- 2 The invention will be )articula rl y explained in the specific description fol-lowing.

Reference is to be had to the accompanying drawings forming a partv of this speci! fication, iniwhieh similar characters of ieference indicate'corresponding parts in all the views. A

Figure 1 is a side elevation 'of an appa-ratus embodying our invention, parts being,r is a front View; and Fig. 3 is a detail transverse vertical section of the driving gear and adjacent parts.

In constructing an apparatus in accordance with our invention,a' post 10 or other suitable support has secured to ita bracket 11 formedwitha sleeve, or`socket` 12, which receivesas'hort, vertical spindle .13, which is normally-heldagainst turning by any suitable meiins, Such as a .set screw 14. On the' upper end offthe' spindle. 13 is the hub 15 of 'integral initcr gears 1G, 17, with one of which meshes a driYingpiiiiOn A18, the shaft 2() of whichhas* afsuitable apparatus,1

the turning of themal'st: the large-gear 23` is free to `run` around 'its driving 'niitergear 17. The relative location of the drive 15in-ion 18 makes'it'possible flor the gear v2I- toiiiake a partial turn. 'L "V The, chute 33 lhas a supportingyokez'ir.

fork 38, kwhiehflispivotally enn'ectdgafs at 39 with an `arm 40, sothat the chteixay roek `in a verticalfplane. The arinllis forked at itsfinner end and maybeseeiired Aadjustably by a pin-41 adaptedto befpasis'eld through any one of the vertical Series -of .pin holes orbo t,lioles, 42 Ain the-.mast A26.,l The arrangement .is such Qthat, the arm .llmayibe 4raised' orlloweiied-'ori .the mast itwary angle of the chute 33, the'chute in its adjustment being free to rock on its pivot 34: and on the pivot 39.

`The prongs 29a are each pivoted as at 29b to their respective links, and the latter are open, as clearly shown in Fig. 2, so that the prong after passing over the upper pulley and dropping the sheave into the chute, will itsell:l drop, the point of the prong entering between the links of thechain so as to clear the parts adjacent to the path of movement. i

-ried by a prong.

By the described Yconstruction it will be seen that the gears 16 17,'may turn relatively to the mast, the latter remaining sta.- tionary, and the gear 23 journaled therein being driven to turn thev sprocket wheels and sprocket chain. AAt the same time the operator has command of the apparatus, and by a pull on the loop 87 may conveniently give a partial turn to the mast with its appurtenances, as may be required for the proper distribution of the sheaves as delivered. l

It will be observed from Fig. 1, that when the'prongs are carried upwardly they gravitate to a position projecting outwardly from the links to,which they are pivoted, there being a shoulder 29 at the base of each prong adapted to seat against the face of the link the face being formed in the present instance by a'bracket member'29 secured to the link, and receiving the pivot pin 29".

:The sheaves to be taken up by the 'prongs 29*l in the upward movement of the latter, are placed upon a table 43, in the form of an open frame secured to the mast 26 above the miter ear 23, the arrangement being such c that a undle placed across the table will be 'v engaged by the pointed end of the next up- Vwardly moving prong and carried upwardly and over the-top sprocket, to be deposited in the chute 33.

Having thus described our invention, we

,claim as new, and desire` to secure by Letters I L 'An apparatus of the character de. "scribed, comprising 'a structure mounted to turn about a vertical axis, an elevating conveyer'carried by the structure, a table comprising an open frame secured to the structure and on which the material is placed, the

conveyer being provided with means for engaging the material on the table and carrymg the same, and a chute pivoted at one end to the structure near the top thereof and adapted to receive the material from the conveyer.

2. In an apparatus of the character described, a mast mounted to turn on a vertical axis, an endless elevating conveyer chain on themas't,y driving means for said chain, said chain having pron s to engage sheaves, and actuating means ger the chain drive', said actuating means including an element carried by the mast and an element adapted to turn on a relatively fixed support below the mast. l

3. `In an apparatus of the character described, a mast mounted to turn on a vertical axis, an endless elevating conveyer chain on `the mast, said chain being provided with prongs to carry sheaves, a chute carried by the. mast near the upper end and adapted to receive material from the conveyer, a table carried by the mast and presenting an opening throughlwhich the chain and its prongs pass in an upward direction, and actuating means for the conveyer, said means being arranged below the mast table.

4. In an apparatus of the character described, a structure adapted to turn on a.

vertical axis, an'endless, elevating conveyer on said mast and adapted to turn therewith, means for driving the conveyer, a chute carried by the mast at the upper end and adapted to receive material from the conveyer, and a flexible tubular extension on the chute, said extension being provided at its lower end with a hand grasp whereby to turn the mast and its appurtenances.

5. In an apparatus of the character described, a structure mounted to turn on a vertical axis, an endless elevating conveyer on said structure and adapted to turn there with, the said conveyerlv being provided with prongs for engaging and carrying shea res, a chute pivoted to the structure near the up per end thereof and adapted to receive material from the conveyer, means for actuating the conveyer, and means for adifxsting the chute to vary the anglo thereof?" In testimony whereof we have signed our names to this specification in the presence of e two subseribingvwitnesses.
