ADJUSTAB LE STAND OR CHAIR FOR ARTISANSf SPECIFICATION forming part of Letters Patent No. 624,567, dated May 9, 1899.

Application filed PebruaryZO, 1899. Serial No. 706,152. (No model.)

To all whom it may concern:

Be it known that I, JULIUS STONE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts,

have invented a newand useful Improvement in Adjustable Stands or Chairs for Artisans,of which the following is a full, clear, and exact description, reference being had to theaccompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a stand or chair for the use of artisans employed on or about the outer wall of a building and which consists in means for the attachment of the stand or chair to the building and also to means for moving the chair both toward and from the wall lengthwise it and perpendicularly with respect to it, which means are connected with the chair or stand and adapted to be operated from it in any of its positions.

Referring to the drawings, Figure 1 is a view in front elevation of my improvement applied to a building. Fig. 2 is a view in side elevation thereof. spective, enlarged, of an adjustable holder, to which reference will hereinafter be made.

In the drawings, A represents the chair or stand. It may be of any desired size and of any form of construction. In the drawings I have represented it as small and adapted to hold a single person. Ihave also represented it as consisting of a base-piece a, which serves as a floor or support and which preferablyhas a front edge a, which is straight or. parallel with the wall of the building, and a curved side and rear edge a It is also represented as suspended by the three chains a a a two i of which chains, a a are attached to the front corners, and the third chain, a is attached to the rear corner. The chains are separated or strained apart by the strainingframe a, over which the chains extend and upon which chains it is vertically ad j ustable,

being fastened at any elevation from the base a by fastening-screws a. The chains at their upper end are attached to a common unitingblock a and this block has a hook a", which hooks into the eye or shackle b of a block B, connected by a suspending and hoisting rope I) with a block B, suspended from a trolley O, which is suspended from a horizontal rail D.

The hoisting rope runs through sheaves in Fig. 3 is a view in per-- the two blocks B B, and its end is attached to the chair or stand, and it affords means for the raising, holding, and lowering of the chair or stand by the occupant of the chair.

The rail D is preferably of flat bar iron and is held by the hooks D D which are of a size to hook over the gutter or edge of a roof of a building, with which roof the points engage. Each hook has a long downwardly-extending shank d, which has extending through its lower end a narrow recess d of a size to re ceive an end of the rail D, which passes through the said recess (1 and has a removable stop d upon its outer end. There is also attached to the lower end of each shank a screw stay-rod E, having a threaded section E,adapt-' ed to turn in a threaded nut e in the shank to adjust the position of the lower end of the shank with respect to the wall of the building. The said stay-rod has its inner ends provided with pointed forks e c, which are horizontally disposed in relation to each other and which bear against the wall of the building and act to stay the lower end of the hookshank. (See Fig. 2.) A locking-screw e ,carried by the shank, serves to lock the shank to the screw stay-rod after the rod has been adjusted, and the stay-rod alsocarries at its outer end an adjustable'collar e, which may screw upon the stay-rod or otherwise be horizontally movable thereon and which upon the adjustment of the stay-rod is moved against the outer edge of the hook-shank and locked against it by a locking-screw e. These suspending-hooks D D are arranged at some distance apart and near the ends of the rail D. When required, an additional reinforcinghook D may be used, This hook is adapted to be movable between the fixed hooks D D and engages the rail by means of a hook (1 formed on its lower end and. upon which the rail rests. The rail also carries, near each of the fixed hooks, preferably near each end, the adjustable blocks F F, each of which is arranged to slide upon the rail and each of Which is adapted to be fastened to the rail by a fastening-screw f. Each of these blocks has suspendedfrom it beneath the rail a roll f, over which a draw-rope f extending in both directions from the trolley C and to the stand or chair A, runs. This rope extends through eyes f on the chair or stand and is long enough to extend to the ground, the chair riding upon it, and the portion of the rope beneath the chair or stand is prevented from twisting by means of a Weighted separatingarm f having eyes f through which the rope runs, and which separates the rope and a Weight f, attached to its center. The rope f is thus brought to a position to permit the occupant of the chair or stand to use it in drawing the trolley C and moving the chair or standhorizontally along the wall of the building in one direction or the other, according to which branch of the rope is pulled. The chair also has attached toit horizontal rods G G, each carrying at its inner end a roll 9, adapted to bear against the Wall of the building. These rods are adjustably secured to the chair or stand to permit it to be set in or out with respect to the said wall, and for this purpose the base a of the chair carries on its under side the rod-holders g, in which the rods are adjustable and to which they are fastened in fixed position by a setscrew 9 These rod-holders are near the sides of the chair or stand, and the rods are thus so located as to prevent the chair or stand from twisting or turning on its supporting-rope.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a device of the character specified the combination of the rail D, its supportinghooks D, D the'trolley O mounted upon said rail, the stand or chair A, the hoisting, supporting and lowering rope b connecting the chair or stand with the trolley, the rolls f adjustably secured to the rail, and the draW-ropef extending from the trolley C over the rolls and thence to the chair A, as and for the purposes described.

2. The combination in a device of the character specified of the chair or stand A suspended from the rail D vertically and horizontally movablein relation thereto, and the rail supports or hooks D, D having depending shanks provided with holes for receiving the ends of the rails, and the-stay-rods E having an adjustable relation to the ends of the and vertically movable with relation thereto,

5. In a device of the character specified the combination of the hooks D, D the rail:

D attached to said hooks, the adjustable forked staying-rods E, the trolley C mounted upon the rail, the adjustable rolls f mounted upon the rail, the chair or stand A, the-hoisting, supporting and lowering rope I) connectin g the chair with the trolley, the trolley-rope f extending from the trolley over said rolls f to the chair and thehorizontally-adjustable rods G carried by said chair or stand.

JULIUS STONE.
