Figure 3 is aside view of the carriage applied to a roof Figure 4 is an enlarged-side view of one of the adjustable supportsfor the carriage Figure .5 is a sectional view on :the line 5+5 ofiFigure 2; and

Figure 6 is an enlarged detail view ofithelower cross zbarandrits supporting pins and rollers.

Referring now to the drawings, my construction stage is made up-of two-carriages II) which are. essentially alike. These carriages are used in pairs as shown in Figure 1 of the drawings.

More than a pair of carriages may, of course, be used if the length of the roof warrants it, The carriages are so constructedthat they may .be used initially from the ground level to start .the roof layingand be supportedirom the peak-of their-00f and used throughout the laying of the roof, with a minimum amountuof tage shifting and resulting loss of time. Since the carriages are essentially duplicates, the description of one will sufiice for both.

. Thecarriage 10 comprises .a frame madeof two side. .bars Ill and 12 which arejoined at the top as-indicated. at J3 toprovide a head piece 14. The headpiece I4 hasahook J5 securely .fastened thereto. The hook I5-is of an open trussed construction asshown to give adequate strength with-lightness. v.A small hook it, is formed as an integralipartrof the hook I5. This small hook is usedfor anchoring the falls.

. The head 14 is. supported above the roof surface by a cross bar I1. The cross bar is securely fastened to the head supported by two rollers .18 and 49.. Eachroller is swivelled on the base of va threaded; stem. 20.. The stem- 20 is threaded in the cross bar I! so that the roller canbe raised .andlowered-with respect to the crossbar. 1The,.roller make the carriage easily shlftableand the adjustability-of the rollers makes it possible. to raise a .roller...and lay .the roofing underneath .it without shifting the carriage.

-.The bars. ILand I2.have.cross.rods 4] connec'iiin ..them.. at relatively close intervals from thehead J4 .tothe lower end thereof. The bars maybe of. any suitable length for the roofing job on whichthey are used. The crossrods are used to-support a bracket 2]. The bracket 21 is made up of metal-strips. It. comprisesa central web portion 22, across bar 23, a.cross bar-24-,an upper book 25, .twovlower diagonal .bars Hand 21,. a bar. .2 8 extending upward from the diagonal. bars andieetliltand at the lower-ends of the diagonalabarsZdand 2]. The web portion 22 has ears 3]. neariitsu-pper enditowhich a platform supporting bar 32 .issecured. This platform supporting bar is alsosecured by a bolt .33 to the bar 28. .-It will be-noted thatthe bar 28.has a series of holes 34 therein sothat the angle of the bar I justable rollers '43 and 44 which are similar in lowered. The reason for providing the pins and rollers in this adjustable fashion is to permit the operator to raise a pin or roller out of the Way while he is placing a shingle or other roofing element on the roof at that particular point. The carriage is so open in construction that it is possible to nail the roofing on either side of the bars II and I 2 and between the bars without difficulty.

A set of falls 41. is provided for each carriage. The set consists of two multiple pulleys 48 and 49 with rings 55 and 5( for attaching them to the hooks I6 and 25, and a rope 52 threaded throughout the pulleys in the usual fashion.

In some cases it is desirable to suspend a similar carriage from one or both of the carriages on a roof for working on the side or end wall.

of a building. In order to utilize the carriage in this fashion, I provide a bracket 53. This bracket comprises a fiat metal body portion having four down turned projections 54 to engage over the sides of. the cross bars l l and I2. Near the upper end of the bracket 53 there is an opening 55 and a hook 58 mounted to operate in this opening. The hook is pivoted by a pin 5'! to an car 58 on the bracket. The hook is adapted to engage the cross bars 4| so as to secure the bracket in a desired position on the carriage. The bracket 53 has a socket member 59 securely mounted thereon near its lower end. This socket member is so fastened that it may support one of the hooks [5 for suspending a carriage at the edge of the roof.

This stage operates from the roof, the two carriages being sustained by the bridged hooks, which provide, for both vertical and roof operations, the positive safeguard to future stage security.

Now to outline briefly the manner of operating the stage, Iwill describe its use in shingling- First the carriages are mounted on the roof and the falls are used to draw the brackets 2| up away from the lower edge. By using the hook holding brackets 53 and additional carriages suspended from them, the initial work at the lower edg of the roof is accomplished, from the .chalk line to a point above the cross bar 42, The pins 45 46 and the rollers 4344 are raised singly as the material is laid under them then lowered and re-set, hand tight to support the carriagev spaced from the roof. When the lower shingling is done then the brackets 53 are removed, the brackets 21 are brought down to their lowermost position. Now the stage is ready for the shingling to advance unobstructed. As the work goes forward the brackets 21 are raised from time to time by the falls 41'. The

hooks

39 and 40 will drop over the cross rods and secure the brackets in each position advanced to.

Thus from the beginning I have, by these novel means, eliminated the street staging as the pre liminary means to all roof work, also the advancing of the dangerous roof cleat with itS.c0ntinual placing and later removal, all of which make no contribution to the actual work in hand.

Now while the stage provides the better way vertically, it further lends itself to ideal conditions for roof work, due to the metal brackets 2i operated by the falls. These brackets have hard rubber feet 29 and 33', that are curved at each end to assure, an even support and easy operation.

The two carriages may be readily moved to new positions, the attached cross bars i1 and 42 being equipped with rollers to insure easy movement. The two carriages provide two hooked ladders which may be used for vertical operations by removal of the cross bars I! and 42.

This specification but briefly outlines the many advantages this stage offers. It is a means not Only to simplify and make more easy and complete the work progress but, from the very nature of its most simplified construction and operation, it does give full assurance to the operator of improved results and of greater safety in his work.

Having thus described my invention, I claim:

1. A construction stage comprising a pair of spaced apart carriages, a hook afiixed to one end of each carriage, support rollers mounted on the carriages adjacent the ends thereof for holding the carriages spaced from a roof, on which they rest, a stage bracket on each carriage, cross bars on the carriages, hooks pivoted on the brackets for engaging the cross bars and holding the brackets in adjusted position, and take-up falls secured to the brackets and to the hook carrying ends of th carriages for moving the brackets upwardly along the roof.

2.'A construction stage comprising a pair of spaced apart carriages, a hook aflixed to one end of'each carriage, support rollers mounted on the carriages adjacent the ends thereof for holding the carriages spaced from a roof, on which they rest, adjustable support pins mounted on the carriages adjacent to the support rollers at the ends thereof opposite the hook carrying ends, said pins being spaced apart and spaced from the adjacent rollers in a direction crosswise of the carriages, a stage bracket on each carriage, cross bars on the carriages, hooks pivoted on the brackets for engaging the cross bars and holding the brackets in adjusted position, and take-up falls secured to the brackets and to the hook carrying ends of the carriages for moving the brackets upwardly along the roof.

3. A construction stage comprising a. pair of like carriages adapted to be mounted on a roof in spaced apart relation to support a platform therebetween for easy adjustment along the carriages from the lower edge to the top of the roof, each carriage comprising a top hook for securing the carriage at the roof top, a frame consisting of side bars and cross rods extending downwardly from the hook, a supporting cross bar secured to the frame adjacent the hook, means mounted on the cross bar for supporting the upper end of the frame above the roof surface, a second cross bar secured to the frame adjacent the end thereof opposite to said hook, and a plurality of supports on said cross bars for holding the said ends of the frame above the roof, said supports being adjustable individually in the cross bars away from the roof to permit laying of shingles, etc., thereunder.
