ELEVATOR were;

T all 'whom it may concern Be='it"kn'0wnthat "I JOSEPH H. RUFF, a citizen'of theUnited States, residing in Lower Allenftownship in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Elevators, of which the follow 'is specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in-"elevators and has relation more particularly to a device of this general character especially designed and adapted for use in delivering sheaves of grain or the like to the-indwbf a barn or any other desired locality}. and the object of the invention isto provide a device'of this general characterhaving novel and improved means whereby the sheaves are readily and effectively engaged and discharged with convenience.

The'inventiouconsists in the details of constrhction and in the combination and ar wo'ahg'ement oi the several parts whereby cer-- tain' importc'nt advantages are attained and the device is rendered sii'n'pler, less expensive and otherwise more'convenient and ad' vantageousfor use, all aswill be hereinafter more fully setfo'rth.

Thenovel teatures'of the invention'will be carefully defined in the appended claims.

In order that my invention may be the, better understood, I "will now' proceed" to describethe same with reference to the ac companying drawings, wherein Figure 1 is a view in side elevation of an elevator constructed in accordance with an embodiment of'my invention {Fig '2 is a view in front elevation of the device as disolosed in Fig: 1, with-certain of the parts being omitted; Fig. a view in rear ele vation of the device; as herein set forth, certeih oi the parts helm; omitted and certain of the parts being shown in F. tion; '4 is a detailed fragmentary view ill elevation illustrating certain features oi? my inv'ere tion; 5 is a view in elevation or a winding pulley herein employed; l lpfi 'ti is it view in side elevation of Fi 5; is a view in top plan of the ta lei herein disclosed, for "controllingthe adjustment of the chute; Fig. 8 is an enlarged fragmen tary view in elevation'illustrating certain details of the elevator, as herein embodied;

and table 2 operative relation. I

The itemsof th' freme's 5 arebrsced'in a well known' manner by the straps or'armsfi,

such straps'or ere serving esfa mounting" for the shaft 7 having fixed at a point subf h the staiitially intern'iediatc its len sprocket Wheel 8 arb und which i'sfe apted' to pass the sprocket chain '9 which extends from suchwheel 8 and aroundaroller'lO ro'tatably supported by and betweentheprd jectedpor'tions 11 of the frames sf'at the" outerend portio'n'ofthe table 2. The-ehain 9 then passes over the table 2 and around the roller-"4 anddown the "forward'rface of the body 1 and around 11 seconds rocket wheel 12 fixed to thesheft "14 mounted in the bearing s15 carried by the'inner face of the body 1, the end portion of'the body 1 being recessed, as at'16, in order to-properly accommodate the sprocket '12. The chain 9 then extendsupwardly"at-=the"rear of the I preferto employ the arra'ngement sh'ownin the' accompanying drawings wherein the shaft 14: is projectedtoone' side-of the body 1, as at 17,130 which projected portion is affixed the pulley18 around which is adapted'jto-be passed a b leading from a suit" I 'able source of power.

The sprocket wheels 8 and 12, as is be lieved to be apparent; determine the osition of the chain 9 which is preferab y at 2 and suitably affixed at predetermined intervals to the chain 9 are the transverse arms 19 extending to either side of the chain 9,

and projecting laterally from the extremities of the arms 19 are the hook members 20, the direction of extension of the hook members 20 being such as to have the hooks of the forward stretch of the chain extended toward the base of the body 1 with the hook portions 21 at substantially right angles to the adjacent face or surface of the body.

When the conveyer is in motion the hook members 20 are caused to engage with the sheaves whereby the same are elevated to the table 2 and from such table 2 are discharged within the chute 22. -Adjacent its inner end portion the chute 22 has aflixed to its under surface the transversely directed strap 23 provided with the centrally disposed bearing block 24 provided in its under surface with an upwardly di rected recess or pocket adapted to accommodate an upstanding lug 25 formed on the outer end of the bracket 26 projecting rearwardly of the body 1 and suitably secured to the frames 5, hereinbefore referred to. The downward movement of the block 24: relative to'the finger or lug 25 is limited by its contact with the table 27 suitably affixed to the bracket 26 adjacent the base of the lug or finger 25 and such table 27 is circular in form and is provided in its rear marginal portions with the notches 37 adapted to be engaged by the dog normally maintained within one of such notches 37 through the medium of the retractable member 39, herein shown as a coil spring anchored at its opposite ends to the block 24 and the dog 38. This dog 38 is provided with the extension 40 to which is secured the end portion of a flexible member l1, herein shown as directed through a suitable opening 42 produced in the hear ing block 24 and directed longitudinally of the chute 22 and passing through an eye 43 or equivalent means depending the chute adjacent its outer end. the opposite end portion of the flexible member is suitably secured to a spool 44 having the spring flanges 45 adapted to frictionally contact with the flexible member ll-and thereby prevent unwinding of such member i1, yet readily separating when it is desired to wind the member 41 upon the spool as the necessities of practice may dictate. By this arrangement, it Willbe observed that the chute is effectively locked in its various adjustments and that such chute is readily manipulated through the medium of the iieXible connection 41, it being obvious that in order to release the dog or latch 38 it is only necessary to create sufficient pull upon the connection and that with the dog or latch 88 in released position the flexible member all can be readily employed forim- I parting the requisite adjusting movement to the chute.

Projecting forwardly of the body 1 and operatively supported by one of the frames 5 is the horizontal arm 28 in which is rotatably mounted a shaft 29 projecting to either side of said arm 28, and to the outer projected portion of the shaft is affixed a sprocket wheel 30 around which is adapted to pass the sprocket chain 31 which also passes around a larger sprocket wheel 32 mounted on a projecting end 33 of the shaft 7. The relative sizes of the sprockets 30 and 82 are such as to cause the shaft 29 to rotate to a greater speed than the travel of the chain 9, for reasons to be hereinafter apparent.

To the inner projected portion of the shaft 29 is removably secured the hub provided with a plurality of radially directed stems or shanks 85 terminating in the forks 36. It is thought to be obvious that the movements of the forks 36 will be away from the body 1 and that the stems or shanks 35 are of such a length as to penetrate and engage the sheaves being elevated along the forward surface of the body 1 and to lift or disengage the same from the hook members 20 and throw such sheaves in a direction opposite to the direction in which the table 2 is extended, this being permitted by the relative differences in the speed of travel of the forks 36 and the chain 9. 'These '36 are only employed when it is desired to throw the sheaves forwardly of the support 1 and are therefore removed from operative position when it is desired to extend the sheaves along the table 2. Any suitable means may be employed for holding the hub 3% to the shaft 29.

From the foregoing description, it is thought to be obvlous that an elevator constructed in accordance with my invention is of an extremely simple and comparatiyely inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which the sheaves may be elevated and delivered as desiged, and it will also be obvious from the-foregoing-description that my invention" is susceptible of some change and modification w'thout material departure from the prinl 1 and spirit thereof, and for this reado not wish to be iinderstood limnyself to the precise arrangement formation of the several parts, shown, in carrying out my invention in practice.

What it claim is An elevator for sheaves comprising body, a vertically'disposed endless con. r operatively supported by the body, wardly' projected arm connected to the body adjacent the upper extremity of the conveyer, a shaft rotatably supported by such arm and fprojecting at opposite sides thereof, such sha t being disposed in advance of the and adapted to penetrate the sheaves lifted by the conveyer and release the same therefrom, and a driving means for the conveyer and the shaft in advance thereof.

In testimony whereof I hereunto aflix my 15 signature in the presence of two witnesses.
