Application led May 18, 1917. Serial No. 169,433.

To all'wlwmiz't may concern.' Be it known that ll, HENRY ARIENS, a citizen of the `United States, and resident of Brillion, in the county of Calumet and State limprovements in hoisting devices and refers especially to such devices adapted for use by molders and the like. i i v The primary object ofmy invention is to provide a. simple and economical portable hoisting device, the same. being especially vdesigned for molders use and so constructed and arrangedthat thelabor of pouring molten metal may be readily accomplished by va single operator, thereby greatly economizing in time and labor. The apparatus is `suspended from any suitable overheadtrack `system in such `manner that the container or vessel can be moved from place to place selected position over a series of molders flasks without exerting any material force in proportion to the load, and, though the lapparat-us is especially designed for molders use, it may be adapted for conveying and pouring various commodities.

1With the above and other objects in view, which jwill appear as the description proceeds, my invention resides in the novel construction, formation Vand arrangement I of parts substantially as herein described and claimed, it being understood that changes in the precise embodiment of the invention l herein disclosed can be made without departing from the spirit of the invention.

In the accompanying drawings l have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode l have so far devised for the practical application of the principles of my invention.

Figure 1 is a view in front elevation of my invention, the track mechanism not being shown. 1

Fig. 2 is a side elevational view thereof.

Fig. 3 is a sectional view taken on the plane indicated by the line3-3 of Fig. 1.

Fig. 4.- is a sectional view taken on the plane indicated by the line L1--11 of Fig. 1, and Fig. 5 is a transverse sectional view taken on the line 5 5 of Fig. 8.,

Referring by characters to the drawings,

5 designates a pair of bail arms that terminate 1n. receiving hooks 6 at the lower ends, said bail arms being connected at their upper ends by a yoke 7 connected with a head piece 8 by means of the bolt 9. This head piece 8 is fixed to the lower end ofthe squared adjustable guide rod 10, said guide rod being guided in the corresponding squared hollow hanger rrod 11, supported by hanger 11 from any suitable track conveyer.

Fixed to the lower end of the hanger 11 is the head block 12 having a pair of laterally down turned arms 13, and formed on the lower endsrlli of these arms arel the bearings for the transverse shaft 15,'said shaft being also journaled in bearings 16 on the central portion of the head block.

Mounted on the shaft 15 intermediate the central portion of the head piece 12, and the arms 13 are a pair of grooved drums 17 adapted to receive the hoisting cables 18 secured at 19 to the headblock 8.

For revolving the drums 17 `to wind the cables 18 thereupon, a chainpulley' 19 is `employed fixed to a shaft 2O and journaled 1n bearings 21 also carried by the downwardly extending arms 13 adjacent the ends thereof. This shaft 20 is in operative engagement with the shaft 15 through the medium of .the tooth gears 22 and 23 car ried by the shafts 15 and 20 respectively.

rllhe wheel 19 is grooved to receive an operating chain 24: which is guided thereon throughmeans of the guiding member 25 carried by one of the arms 13.

y Thus it will be seen that when the wheel 19 is revolved through the chain 24, the shaft 20, will, through the medium of the gears 22 and 23, revolve the drums 17, thus causing the guide rod 10 to be lifted or lowered as the case may be. It is apparent that the guide rod 10 is slidable in the sleeved hanger 11 and is prevented from a swinging movement by its squared faces.

To govern the downward movement of the hoist, a brake band 26 is utilized engaging a brake drum 27 fixed to the wheel 19. The brake band 26 has its ends pivoted to arms 28 formed on the inner end of the weighted lever or fulcrum 29 pivotally secured at 30 to the head piece 12.V As will be readily seen by referenceto Fig. 4, this brake is at all times in binding'engagement with the drum 27, and whenV it is desired te release 45 piece fixed to the lower end of thehanger the "brake, a lever 3l is employedhattacliegl to the outer end of the lever 29.

i Thus it Will bereadily apparent from theV foregoing description taken in -connection with the accompanying drawings, that I have provided a simple and efficient device pf ythis character, andwhile I haverilluslY"crafted-my invention asemployedn lifting or hoisting a molders pouring vessel 32, it will be understood that my invention may arms 5 from the head block 8, and replace What is claimed is l.jA.'device lof the character described icomprising 'ahead'piece having arms` y formed thereon, a guide rod carried by said head ,pieceI and adjnstably guided therein interl mediate Athe arms ofsaid head piece, workreceiving means carried by the guide rod, hoistingdrums jonrnaled in the arms of said 7head piece, and hoisting cables Wound about ,said drums 'and engaging said guide rod to operate the device.

f2. devicel of the character described "comprising, in combination, a sleeved hanger :rod, aguide rod slidably mounted therein, a

'headxblock fixed to the lower end of the guide rod and adapted for engagement with workrto be hoisted, a head piece mounted on the lower end of the hanger rod, hoisting Y drums having their shafts journaled in bearings carried by the head piece, hoisting cables connected with the head block and `adapted to be wound upon said drums, and

means for revolving the drums to operate the device substantially as described.

b, In a portable hoisting device, the combinationpvvith a hanger rod, of a guide `rod lslidably carried thereby and having work engaging means on its lower end, a head rod, laterally and downwardly extending arms carried by the head piece, hoisting drums intermediate the ends of` said arms, means for revolving said drums, hoisting cablessecuredto the lower end ofthe guide adapted to be wound upon the drums and braking means for governing the operation of said drums.

4. A device of the class described comprising a sleeved hanger rod, a guide rod slidably mounted therein, a head piece having a central portion fixed to the lower end of the hanger rod, laterally down-turned arms formed on thehead piece, a pair of parallel shafts journaled in said arms, a pair of hoisting drums carried by one of said shafts, a manually voperated Wheel fixed to one end of theother of Vsaid shafts, gears carried by both of said shafts and in. mesh with each other, and hoisting cables fixed to the lower end of `the guide rod and adapted to be wound upon the hoisting drums.

`5. A device of the class described comprising a sleeved hanger rod, a guide rod slidably mounted therein, a head piece having a central portion fixed to the lower end of the hanger rod, laterally down-turned arms-formed on the head piece, arpair of parallel shafts liournaled in said arms, a pair of hoisting drums carried by one of said shafts,a manually operated wheel fixed to one end of the other of said shafts, gears carried by both of said shafts and in mesh With each other, hoisting cables fixed to the lower end of the guide rod and adapted to be wound upon the hoisting drums, and braking means for governing the movement of the hoisting drums substantially as described. e

6. A device of the character described comprising a head piece including a central guide portion and a pair of laterally down turned arms, a guide rod adjustably mountedI in said central guide portion of the. head piece, a head; block carried by said guide rod and adapted for engagement with the work to be hoisted, hoisting means mount-ed between the, arms and Central portion of the head piece, andconnections between. said hoisting means and said head block of the guide. rod to operate the device.

In testimony that I claim the foregoing I have hereuntofset my hand at Brillion in the county of Calumet and State of lllisconsin.
