WILLIAMi EDWARD BOEHCK. OF JERSEY CITY. NEN JERSEY. ASSIGNOR TO NEW YORIA REVOLVING PORTABLE ELEVATOR COMPANY, OF JERSEY CITY. NEW JERSEY, A

CORPORATION OF NEW JERSEY.

SECTIONAL PORTABLE ELEVATOR.

To all when: it may concern Be it known that I, lViLmLiM Eownnn Bomicit, :v subject of the lhnperor o'l' Ger-- many. residing zit Jer ey City, in the county of l'ludson and State of New Jersey, have invented certain new and useful lmpr i ments in Sectional Portuhle I llevntors. oi which the following :i si'nrilicution. reference being had to the nccomniuvinp: drn win gs.

This invention relates to improvements in portable elevators or tiering machines; and an object, of this invention is to provide :1 portable elevator or tiering machine the height of which may be varied for any de sired purpose such as that the machine may be drawn tlllollgl'l doorways in passing from room to room of the warehouse or other place in which it is used.

In the drawings illustrating the principle of this invention and the heat mode now known to me of applying that principle. Figure 1 is a side elevation of a portable elevator or tiering machine embodying this invention; Fig. 2 is a front elevation or view taken in the direction of the arrow A in Fig. 1; and Fig 3 is n detail'ot' the sheave bracket.

The base a is mounted upon the truck 7), which is provided with two rear wheels 0 and n caster or st ering wheel a. The innchine is drawn fr m place to place by means of a handle 1' l'nstcncd to the mounting: of the steering-wliech From the has? rr there rises pair of side. standards i wh ch constitute side in inlwrs ot a Vti'l'itni ninin guide-frame which is stiti'encd and strengthened by means of horizontal and inclined braces g, h. (entrnllvdisposed between thrside frameuuemhers f is a suhfrnmc i the lower end of which is supported by the hose a and the upper end of which is fastened to one of the horizontal brace-members {7. In this suhfriune 'i there are mounted it Windlass-drum shaft j an intermediate shaft Z and nil operating shaft m. Upon the lowermost or Windlass-drum shaft there is mounted a Windlass-drum n and a spurgear 0 fixedly 'mnected with the latter and. in mesh with a pinion ,v m unted upon the intermediate shaft 7:. Upon the intermedi' ate shaft Z: there is mounted a SlJllF-Z921F q whioh meshes with a pinion r fastened upon the topmost or operating-shaft m, the trout Patented Aug. 4, 191s Serial No. 762,237.

nd of Which projects beyond the front upright 1" of the sul'ifrume i and is adapted to ho engaged h v the operating crank it. l on the ti-pni'sl shaft m there is also m unted it lu'ukc-(lisk t which is controlled li v u hrnltc-strnp i r other suitable brake Hiillllwl'h. Mounted tree to slide in the side standards 1 of the main trume is a loadcnrr viu pluli' rni n to which is fastened one end of :l rnhlc w the other end of which is wound nround the windlnssdrmn n. The parts l'iereinhefore des ribed nre old and well-known and are shown in the United States patent granted Thonnis James Mc- (nrtl Xo 834,961, granted May 2%, 1907.

At the upper cud of each of the side memhers f of the main frame there is fastened n h rixontnllv-tlis wsed plate .r to the outer end of which pivotslly connected or hinged at 5; a. Similul horizontally-disposed plate wh ch is fnstened to the lower end of one of the side .n'ieinhers f of the intermediate section 2. The main t'rnme and the latter are held normnlly locked together by menus of n locxingliolt 3 and nut 4 In an entirely similar manner the upper secti n 5 is hinged to the intermediate section 2 m d held normally l cked by a locking: hull; and nut: and it will be understood that. the number of sections is not limited but may he increased or (ltl'ltllSeil at will. he side memi'iers f. f" of the sections '2, 5. are in line with the standards or side members f of the ma n l'rzunc and form with the latter is m nt nuw nuidcw'ay for the liu'ltl-tltlllylug plnih-iui r. Furthermorm the sections nre braced hy horizon'tnl and inclined braces 7, In suhstnntinlly in the some mnnner in which the main frame is hrnred. In the main frame and in each of the sections there fasten d to one of the h riitontnl frame ineinhcrs n contrallv'disp sed sheavehrnvket who-h is U-shnpcd und in the lower end of which there is mounted a removable shaft 7 which is adapted to support the sheave 1*: over which passes the cable w. The slieuvo-slmft T is held in place by means of cotter pins l.

\l'hcn it is desired to move the tiering machine fr m IOfllll tO room, it will be fullhti height of the machine so that it may pass through the doorway h v means of which the two rooms ronununicutc, To vary the generally necessary to vary the' height of the machine, one of the cotter pins 9 is removed and the sheave-shaft 7 is taken out 40f the topmost sheave-bracket 6 and placed together with the sheave 8 in one of the lower brackets. Then the looking nuts 4 are loosened and the locking bolts 3 are re moved, after which the uppermost section is swung into the dotted line position shown in Fig. 1. If after lowerin the topmost section it is found that the eight of the machine is still too great to enable it to pass through the doorway, the intermediate section 2 is swung upon its hinges in an entirely similar manner. t 0 machine has passed through the doorway into the proper room, the lowered section or sections may be raised into their Proper position. Of course, the provisiono the hinged extension sectionsmakes it ossible to vary the reach or range of action of the tiering machine, as well as adapts it for being moved from room to room through the doorways by means of which the same communicate.

In acordance with the provisions of the patent statutes I have described the principle of operation of m invention, together with the apparatus w ich I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only representative and that the invention can be carried out.

by other means.

I claim:

1. A sectional tiering machine having a 85 main frame provided at its upper end with a laterally-extending arm; an extension section provided at its lower. end with a laterally-extending arm, said arms being hingedly connected and said section being normally in prolongation of said main frame; a load-carrying platform mounted free to move in said frame and section; and mechanism for raising said platform.

2. A sectional tierlng machine having a main frame provided at its upper end with a laterally-extending arm; an extension section provided at its lower end with a laterally-extending arm, said arms being hingedly connected and said section being normally in prolongation of said main frame; a load-carryin platform mounted free to move in said rame and section; a cable one end of which is attached to said load-carrying platform; mechanism for winding up the other end of said cable; and a movable sheave over which said cable runs and which is transferable back and forth between said section and main frame.

Signed at Jersey City, in the county of Hudson and State of New Jerse this seventeenth day of April, 1913, in t e presence of the two undersigned witnesses.
