HOISTING APPARATUS.
Specification of Letters Patent.
.PatentedOct.15,1912.
Application flied necembe 'is, 1911. Serial No. 666,330.
To all whom it may concern:
Be it known that I, Cimnnns Gans'rnNs, a citizen of the United States, resii'ling at Davenport, in the county or Scott and btate of Iowa, have invented certain new and. useful. Improvements in Hoisting Apparatus; and I do declare the following to be a. lull, 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. v
This invention relates to improvements in hoisting apparatus.
One object of the invention is to provide a hoisting apparatus having an improved construction and arrangement oi carrier and means for operatively connecting the same with the track bars of the hoisting frame whereby the carriage is prevented from becoming disengaged from the ti'acltbars while being raised and lowered thereon.
Another object is to provide a. hoisting apparatus which will be simple, strong durable and inexpensive in construction, ellicienband. reliable in operation and which is particularly adapted for hoisting ice into refrigerators or ice boxes.
With these and other objects in view the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.
In the accompanying drawings: Figure 1 is a front view of my improved hoisting apparatus showing the carriagoin a lowered position; Fig. 2 is a vertical sectional view showing the carriage in a. partly elevated position; Fig. 3 is a detail perspective viewof the carnage; Fig. 4 is a cross sectional. View through the hoisting frame and the carriage on the line 41--t of Fig. 1 showing the manner in which the latter is secured in operative engagement with the traclc bars of the frame.
In the embodiment of the invention, 1 pro vide a carriage supporting frame 1 comprising a pair of track bars 2 which are preferably T or angle iron shape in cross section and have their upper ends curved or turned inwardly to a slight extent shown. The curved upper ends of the track bars are connected together by an upper cross bar 3, while the main portion of the bars 2 are connected together at intervals by a plurality of cross bars 4, said bars being spaced at suitable distances apart to permit the frame to be employed as a ladder. '1 wo of the bars 4 near the lower ends of the frame are flattened and have bolted or otherwise secured thereto the ends of a. pair of Windlass supporting bars 5 to which are secured suitable bearings (3. in the bearings (3 is revolubly mounted a shaft 7 having fixed thereon between the bars 5 a cable winding drum 8. On one end of the drum 8 is fixed a ratchet gear 9 with which is engaged a pawl 10 whereby the drum is held against retrograde niovcnu-nt. ()n the outer end of the shaft 7 is tormeda crank handle 11. whereby the drum is turned in-lhe proper direction for winding or unwinding a carriage hoisting cable 12.
Secured at their upper ends to the end cross bar 3 and at their lower ends to. the upper cross bar 4- is a pair of pulley supporting bars 1?, said bars'having the same curvature as the curved upper end of the track bars ltevolubly mounted between the bars 12} is a cable guiding pulley 14 around which the carriage hoisting cable 12 passes from the carriage 15 to the drum whereby when the cable is wound on the drlun the carriage will bedrawn up the track bars and when the pawl 10 is disengaged "from the ratchet. gear 1) and the drum turned in a reverse direction the carriage will lower.
The carriage 1;) comprises a frame consisting of cross bars 16 the ends of which are bent inwardly at right angles adjacent to the outer edges of the track bars 2 as shown. lievolubly mounted on hearing bolts 1.7 in the upper portion of the angular ends of the bars 16 are carriage supporting rollms 1% which are adapted to travel on the upper sides of the track bars 2, while on similar bearing bolts 19 in the outer portion of the angular ends ol the bars 16 are revolubly mounted carriage retaining rollers 20 which engage the under sides of the upper portions of the track bars and hold the carriage in o 'ierative engagement with the track while being raised and lowered by the cable 12 in the manner described As clearly shown in Fig. 4 the rigid projecting arms of the carriage 15 are each provided with a pair oi alining guiding and holding rollers which are properly proportioned and arranged in such a manner as to closely engage with the T-shaped track bars,
the retaining rollers being considerably the lower ends of which are bent upwardly at substantially right angles to form supporting arms 22 which are connected together at their upper ends by a cross bar 23. The upper or outer ends of the arms 22 have formed thereon inwardly extending spurs 24- Which engage the ice or other object placed on the carriage and prevents the same from slipping off, The cross bars 16 of the carriage frame are further braced by diagonally arranged brace bars 21 secured at their ends to the bars 16 as shown.
By constructing the hoisting apparatus asherein shown and described it will be seen that the frame thereof may be employed as a ladder-for climbing into the ice box or refrigerator or to any elevated position which the frame will reach. The frame may be constructed of any desired length and the side bars thereof will form tracks upon which the carriage 'is adapted to travel when raised or lowered in themanner described,
said carriage being operatively secured to the tracks by the supporting and retaining rollers 18 and 20 which prevent the carriage from becoming disengaged from the tracks irrespective of the position or inclination of the supporting frame' From the foregoing description taken in connection with the accompanying drawings, the construction and, operation of the "invention will be readily understood Without requiring a more extended explanation.
Various changes in the form, proportion and the minor details of construction may be resorted to Without departing from the principle orflsacrificing any of the advantagcs of the invention as claimed.
Having thus described my invention, what I claim is; v
In a hoisting apparatus comprising a supporting frame the latter consisting of parallel T-shaped tracks rigidly connected, a carriage having rigid arms projecting therefrom, alining rollers mounted in said arms and adapted for engagement with the outer, fiat face and one side of the rail with the roller carrying arms disposed in close rela tion to the "outer edges of the tracks whereby the carriage is prevented from lateral movement and becoming-released from the rails, and a raising and lowering mechanism arranged on said frame and flexibly at e tached t0 the carriage.
In testimony whereof I have hereunto set my hand in presence'of two subscribing witnesses.
