LADDER-PULLEY-BLOCK SUPPORT.

Application filed July 19,

The object of this invention is to provide a pulley block support which utilizes a ladder and the roof of a house where the ladder and pulley block are wanted for use, in providing a strong, convenient, and safe hoist for such building material as is handled in house construction and repair.

I accomplish the above and other minor objects which will hereinafter appear, by the mechanism illustrated in the accompanying drawing, in which Fig. 1, is a view in front elevation of a ladder positioned for use against a house,

. and forming with the house, a support for a pulley block;

Fig. 2, is aside elevation of the ladder and. vertical section of the house with the pulley block support illustrated in Fig. 1;

Fig. 3, is a top end View of the clamp for attaching a block supporting bar to a vertical bar of a ladder;

Fig. 4, is a. perspective view of the socket member of the clamp looking at its inner side; and

Fig. 5, is a perspective view of the other member of the clamp, also looking at its inner side.

Like characters of reference indicate like parts in the several views of the drawing.

A ladder of usual construction, having the bars 6 and rungs 7, is supported from the roof or roof sheeting 8 of a house by a frame 9. having a rectangularly slotted member 10, through which the ladder passes and in which it is clamped by the contact of the sides of the member 10 with the bars 6, when the ladder is tilted. Said frame 9 also has an extension 11, connected by hinges 12, 12. The extension lays fiat upon the roof sheet ing 8, to which it may be removably secured by suitable nails.

A metal bar or pipe 12 is attached in an outwardly sloping position, to one of the bars 6, of the ladder by a clamp 13 which will presently be described. The upper end of the bar 12 is bent outwardly or in a direct-ion away from the ladder, and is provided with a vertical hole in which an eye-bolt 14 is secured. The hook of a pulley block 15 is attached to the eye of bolt 1 1. The block 15 here shown supports two pulleys but the number is optional and is part of any usual and suitable block and tackle for hoisting purposes, terminating with a lower block 16 and hook on which the load is hung.

A brace bar 17 has its upper end bent as 1826. Serial No. 123,518.

shown and perforated for'its attachment to the bolt 14 at that end. The lower end of bar 17 is hinged to cars 18 of a shoe 19. The shoe 19 rests upon the roof or sheeting 8, and has holes for the passage of nails 20 by which the shoe is fastened to the roof.

A swivel joint which will allow the shoe to be placed at different angles on the roof is formed by cutting the bar in two, threading the adjacent ends and screwing them loosely in opposite ends of a sleeve 36.

The clamp 13 is in two parts 21 and 22, having opposite channels 23 and 2 1, in which the bar of the ladder is grasped. The two parts 21 and 22, are brought together to clamp the bar between them by means of a pair of bolts 25, 25, which are tightened by wingnuts 26, 26. The heads of the bolts are preferably seated in correspondingly shaped sockets in plate 21 shown by dotted lines in Fig. 3 to keep them from turning. The plate 21 also has an extension with a channel 27 partly closed longitudinally by an overhanging rib 28, and closed at one end 29. The member 22 has a corresponding extension terminating with a flange 30 of a size and shape adapted to and which is loosely seated in the channel 27, into which it is inserted by sliding it in endwise through the open end of the channel. The fit of flange 30 in channel 27 is sufliciently loose to provide a hinge joint between members 21 and 22 that will allow the two members to be opened or closed sufficiently to fit the clamp to ladder bars 6 of different sizes.

Cast as an integral part of the clamp member 21 is a cylinder 33 the bore of which forms a socket to secure and hold the lower end of the bar 12. The bottom of the socket may be entirely closed or only partially so, as by the inside flange 34, shown in dotted lines in Fig. 3.

WVhile I have shown my invention with considerable particularity and detail, it is capable of various modifications without departing from the spirit of the invention and I therefore do not desire to be limited to the precise mechanism illustrated, nor more than is required by the appended claims.

I claim:

1. The combination, with a ladder adapted to be supported from a house, a clamp on the ladder having a socket extending obliquely of the ladder, a bar seated in the socket and extending on the side of the ladder remote from the house, a block and tackle, and means for supporting the block and tackle from the outer end of the bar.

2. The combination, with a ladder of means for supporting it from a house, a clamp on the ladder having socket, a bar seated in the socket and extending outwardly of the ladder, a block and tackle, means for supporting the block and tackle from the outer portion of the bar, and a brace bar extending from the outer portion of the first bar and adapted to be connected to a roof.

3. The combination, with a ladder adapted to be supported from a house, a clamp on the ladder having a socket, a bar seated in the socket and extending; outwardly of the ladder, a block and tackle, means for supporting the block and tackle from the outer portion of the bar, a brace bar extending from the outer portion of the first bar and shaped to be connected to a roof, a shoe hinged on the roof-end of the second bar and a swivel joint between the bar and its shoe.

In testimony whereof I afiix my signature.

PAUL Gr. GAUSS.
