2- Claims; (Cl. 304- 21) The present invention relates to a shinglin'g scaffold and it consists in the combinations, constructions and arrangenients 5f parts herein described and claimed;

Generally there is provided a shingling scaffold com pr-isi'ii' an open rectangular name one of the longer sides or is provided with root tre'e engagin'g feet while the other of the longer sides is provided with a pair of elevating feet. A frame including a pair of spaced rails is mounted by means of rollers upon the two longer sides of the main frame and has an operators seat mounted upon such rails for movement upwardly and downwardly in parallel spaced relation to the face of a slanting. roof. The seat is nieyed upwardly and downwardly by means ofa cane eom'ieet'ed thereto at one of its ends and ex;- t'ending over-a follf or pduey the uppermost portion or the seat name and capable of being tied at its other end to the seat a ee'ted position has been fonnd for the latter. Nova means is also provided, including a winch and a novel arrangement of cables and ulleys fdr' moving the seat frame in its entirety in a lateral difofior'i Willi respect to a dlafifihg' 'iob'f. There is also provided novel for aligning" shingles to be attached to the roof, The device contains rnan other novel features which will be Brought out in the appended specifiatioii. I

t is aoidifigly an Gfij iifiif the i'fiiifltion to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and eflicient in use.

Another object of the invention is to provide, in a device of the character set forth, an operators seat and novel means for moving the same to selected positions upon a roof.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 1 is a perspective view of an embodiment of the invention shown in position upon a roof,

Figure 2 is a vertical sectional view thereof, and

Figure 3 is a fragmentary plan View of the device illustrated in Figures 1 and 2.

Referring more particularly to the drawings, there is shown therein a device of the character set forth comprising a main frame generally indicated at and consisting of an upper horizontally extending tubular track member 11, a lower horizontally extending tubular track member 12 and a pair of tubular end members 13 and 14 which interconnect the ends of the members 11 and 12. A pair of vertically extending anchoring feet 15 is mounted upon the tubular member 11, one adjacent each end thereof and each is provided with an inverted V- shaped bottom 16 adapted to receive therein the peak portion 17 of a sloping roof 18.

The upper end of each of the anchoring feet 15 is provided with an eye 19 whereby :a cable 20 may be fastened thereto, it being understood that the opposite ends of the cables 20 may be fastened to some secure device whereby to insure against slippage of the device of the present invention from the roof 18.

2,814,533 Patented Nov. 26, 1 957 2 A carriage is generally indicated at 21 and it consists of an upper transverse member 22 and a lower transverse member 23- which are interconnected witha pair of spaced parallel tubular rails 24. The upper end of the carriage 21 is supported by a pair of rollers 25- carried by the member 22 and engaged upon the tubular member 11 and a flanged roller 26 carried by the member 23 and engaged with the tubular member 12.-

A seat 27 is carried by a frame 28 which is supplied with a pair of rear rollers 29 each engaging; the upper side of one of the members 24; a pair of intermediaterollers 30 each engaging. the underside of one of the members 24; and a pair of forward rollers 31 each eugaging the upper side of one of the members 24.

A winch 32 is mounted upon the rear of the seat 27 and is provided with operating handles 33 and 34 at opposite sides thereof. Two cables 35 and 36 are wound upon the winch 32 in opposite directions. The cable 35 extends from the winch to a pulley 37 carried by the member 23 and thence to a pulley 38 carried by the lower portion of the member 13 from which it proceeds" to a pulley 39 carried by the upper end portion of the member 13 after which it extends to an anchor block 40 mounted upon the inner side of the member 21. The cable 36 extends downwardly to a pulley 37a; thence to a pulley 41 carried by the lower end portion of the member 14; thence to a pulley 42 carried by the upper end portion of the member 14'; and thence to an anchoring block 43,- likewise carried by the member 21. The free ends of the cables 35 and 3-6 are respectively t iedito the anchoring blocks 40 and 43. Upon the member 12 adjacent each end thereof is a supporting foot44; A supply of shingles 45 may be carried upon the seat 27,- as shown in Figures 1 and 2. An aligning bar 46 is mounted upon the outer ends of levers 47 which are pivoted at their inner ends, as indicated at 48, to brackets 49 mounted upon the underside of theseat '27.

An operating handle 50' extends-through a slot 51: in

one side of the seat 27 and is provided with a forwardly extending dog 52. The handle 50 is pivoted at its lower end to one of the levers 47.

A pull rope 53 is connected at one of its ends to an eye 54 centrally mounted upon the forward end of the seat 27 and extends thence upwardly to a pulley 55 and thence downwardly again to the seat 27 where it is tied. A roller 56 is mounted centrally upon the member 22 and extends forwardly thereof and bears against the underside of the tubular member 11.

'In operation, it will be apparent that the main frame 10 may be mounted upon one side of a sloping roof, as shown in the drawings while placing the V-shaped opening 16 over the peaked portion of the roof and then allowing the device of the present invention to rest upon the one side of the roof with the feet 44 supporting the same at the lower end thereof. To insure against slippage of the device from the roof, the cables 20 may be extended to suitable anchoring means (not shown). 'It will be apparent that the seat 27 may now 'be moved upwardly and downwardly upon the face of the roof by manipulating the pull rope 53, it being apparent that by paying out the same, the seat 27 will lower by gravity toward the member 12 whereas, when it is desired to move the seat upwardly toward the peak of the roof, it is only necessary to draw the same inwardly and to tie the same when the desired point has been reached. It will also be apparent that the entire carriage 21 may be moved in a horizontal direction along the members 11 and 12 by selectively turning the handles 33 and 34, it being apparent that as the cable 36 is Wound upon the winch 32 that the carriage 21 must perforce move to the right as viewed in Figure 1 while at the same time the cable 35 will pay out from the winch 32 making such movement possible. To move in the opposite direction, it is only necessary to wind up the cable 35 upon the winch 32 whereupon the other cable 36 will pay out permitting such movement. Thus it will be seen that the seat 27 may be moved to any desired position upon thereof 18. When a single shingle 45 has been aflixed to the roof 18, the aligning bar 46 may be placed against the lower end thereof whereupon additional shingles 45 may be placed against the aligning bar 46 and then fastened to the roof by nails or the like thus insuring perfectly straight lines of shingles upon the roof 18.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.

What is claimed is:
