Specification of Letters Patent. Application fled October 12, 1911.
To aZZ whom t may concern.' structures may differ decidedly,
Be itv known that I, CHAImEs'M. HAYNEs, l illustrated the platform structure comprises a citizen of the United States, residing at a pair of parallel members 7 and vt3, While Tewark, in the county of Essex and State the reel structure also comprises a pair of have invented certain new parallel members 9 and 10. The members 7 and useful Improvements,inHanging Scat'- and 8 1n the present case constltute platfolds, of which the following is a specificaform supporting members, and they may be tion. bridged by planks or boards as l1 to pre- This invention relates to hanging scafsent a platform or deck folds, the ob'ect of the invention being to Workmen stand, provide an ellective'apparattts ci' this charspectivetrades. acter 'by which the workmen on the platform adapted to be crossed by boards-0r planks e scaffold Willbe protected against ln* .Jury from objects falling: from above said and by which several suspendingv simultaneously or in advantage when 1t 1s remembered that articles are constantly falling. from points above j ured by such falling objects.

F 2 13S; a detail view in ele-vation cgt reel mechanism, and, Figs 3 and l are top plan and Side elevations oi" saidreel bles beinfglconnec-ted with overhead beams or gir-ders each denoted by 17 and which overhead beams Like characters refer lto. y like partsthronghout the several figures of the draw'- As will hereinafter appear# a shown, being designated respectively in a general Way by 18-and 19, the reel mecha nism 1 8 being shown in detail in Figs. 2 to 4t inclusive.
A specific description ofl one mechanisms?- Will apply are duplicates, and this hereinafter given.' y At this time I might state that the cables 18 and 14 are Windable upon thereel mecha- 4nism 18, While the cables 15 and 16 are simi- "larly operative by the reel mechanism 19. n the present instance the several cables depend from the overhead bea-ms 17 and extend through perfor-'ations as 2O near the ends of the beams orgirders 9 and l0 and under guide sheaves Aa`: s 21 located beneath of the reel to the other as they description will be some part thereof l or y which one or more of the support-ino,1v Cables for the scaffold may be operated inor some simi-lar part and as. to details, this reel mechanism mayV vary radically; that is, it may be employed successfully with scaffolds ofsvarious structures, although AaI scafdvantag'eous is `illustrated in -`ig.` 1 of the rawings. scaffold comprises in its make-up a platform structure 5 and a reel structure 6;
- of which they can respective beams f anism 18, which is shown in detail in Figs The side bars of the supporting frame 31 said perfor-ations. The upper ends of the cables are passed through appropriate holes in the supporting beams 17, the free portions of the cables being clamped to the bodies thereof by nieansof clamps as 22.
It will be understood that by turning the reel mechanisms 18 and 19 as will hereinafter appear,v in one direction the several described cables may be wound thereupon to elevate the scaffold, while by paying Oif the cables from said reel mechanisms, said scaffold can be lowered.
Situated near opposite ends of the two side members or beams 9 and 10 are *yok'es each denoted by 23, the upper cross bars of which are perforated, and through the perforations the several supporting cables pass. In the present instance the several yokes or hails 23 are pivotally supported, by virtue be folded down upon the 9 and 10 t thereby save space in storage or transportation, The pivots for this purpose are denoted in each instance by 24. The primary purpose of these yokes or hails 23 is to prevent the beams 9 and 10 from turning turtle. The sides of the yokes 23 are continued below the two beams 9 and 10 and converge, be ing connected below said beams by and various means may curing these results. By operating all the spools together, the scaffold as a unit can be either raised or lowered, while by operating one or more spools or drums independent of the remainder, the platform supporting structure may be leveled, so that owing to this condition each reel mechanism performs a double office. The spool or drum 33 has rigidly connected therewith a worm gear 35, while the spool or drum 34 has a sub stantially similar` worm gear 36 also rigidly connected therewith.
` In mesh with the worm gear 36 is a worm 37, the shaft 38 of which is rigidly connected therewith and is supported by a bracket or bearing 39 upon the spool 33. "he worin gear is in mesh with the worin 40, the shaft 41 of which is sustained for rotation by a bracket 42 side of the frame 31. To said shaft is fastened a gear 43 in mesh with the companion gear 44, the shaft of which is provided with an operating` device such as the hand crank 45. It will be clearthat the worm 37 and the worm gear 38 normally lock together the two spools 33 and 34, so that when the spool 33 is turned through the primary iniuence of the hand crank 45 or otherwise, said spools 33 and 34 will be operated as one, by reason of which all four of the cables 13, 14, v 15 and 16 can be either reeled onto or off the two sets of spools 33 and 34 simul taiieously to accomplish which in the present instance, it is necessary to actuate the two cranks 45 or their equivalents at the same time or practically so. By rotating the shaft 38 the worm 37 will be turned so as to thereby operate the worm gear 36 and hence the spool 34 whereby said spool can in like its cable and by be provided for scbolts or other pins 25, around which the sustaining cables 2G for the platform supporting structure are passed and held by clamps 27. The platform supporting members 7 and 8 are provided with bolts 28 around which the lower portions of said cables 26 are carried and held by clamps 29. It will, therefore', be clear that the platform supporting structure is iiexibly supported .by the reel mechanism carrier, so that when said reel mechanism carrier is raised or lowered, corresponding results will follow with respect to the platform structure. Each side member or beam 9 is shown as arched as at 30 between the ends thereof and under the respective arches the reel mechanism is supported, being carried in the present instance by substantially `rectangular frames as 31. I will now describe in manner either reel on or olf such individual operation of any one spool the leveling of the scaffold can be obtained. The worm shaft 38 is shown provided at its ends with duplicate fixed collars 46 having holes to receive an operating rod, bar orgits equivalent by'which said shaft 38 can be rotated.
In conclusion I desire to call attention to the fact that the primary operating elements for the reel mechanisms are situated below the reel carrying structure so that the workmen while on --the platform or platform structure can readilyv operate the hereinbefore described hand cranks constitutingv in the construction illustrated such primary operating elements and this without any fear of being injured. Furthermore the worm carrying bracket 42 as shown 'in Fig. 1 may be swung on a pivot as 47 thereby Ypermitting disengagement of the worm 40 and worm gear 35 so that the latter will be free to turn independently of the hand crank and interposed gears, to thus Jfacilitate the rapid detail the reel mechsaid reel mechanism beingl a 2 to 4 inclusive,

counterpart of have bearings to sustain the shaft 32 upon which are loosely mounted primary and sec-V ondary spools 33 and 34 respectively, which as will be understood, are coaxial, and although they are shown as supported by a common shaft, this is not essential. Said spools 33 and 34 as shown are in juxtaposi tion. Neither is it essential that I employ two spools. I may employ any other lnumber dependiA upon the number of cables to be operated upon. These spools or drums are adapted to be operated simultaneously or one of them to be independently operated,
