Application filed. June 4, 1910. Serial No. 564,972.

To all whom it may concern:

Be it known that I, CHARLES H. TABER, a citizen of the United States, and a resident of lVoodlawn, in the county of Beaver and State of Pennsylvania, have invented a new and Improved Combined Papering Board and Scaflold, of which the following is a full, clear, and exact description.

My invention relates to papering boards and scaffolds, and it has for its object to provide one in which the papering board is supported on the scaffold, making it unneces sary for the workmen to climb down from the scaffold to paste each strip of paper.

Another object of the invention is to so construct and assemble the parts that the combined board and scaffold may be ad justed as to height and length to meet all requirements. The device is also so constructed that it may be readily knocked down, which will facilitate its transportation.

Still other objects of the invention will appear in the following complete description.

In this specification I will describe the preferred form of my invention, it being understood that the scope of the invention is defined in the appended claims.

Reference is to be had to the accompany ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which F igure 1 is a perspective view of the invention; Fig. 2 is a side elevation of the device when it has been knocked down for transportation; Fig. 3 is an inverted plan view of the invention; Fig. 4 is a transverse sectional view showing details of the construction; Fig. 5 is a fragmentary view showing the method of securing the brace members to the auxiliary members of the platform; and Fig. 6 is a sectional fragmentary View showing the method of securing the members of the extension legs relatively to each other.

By referring to the drawings it will be seen that an extensible platform 5 is pro vided, having a main member 6 and two auxiliary members 7. The auxiliary members 7 are disposed under the main member 6, the combined length of the auxiliary members being substantially the same as the length of the main member. Guide members 8 are secured to the sides of the auxiliary members 7, the guide members engaging the top of the main member 6, similar guide members 9 being secured to the sides of the main member 6 and engaging the under side of the auxiliary members 7 respectively. With this construction it will be seen that it is possible to move the auxiliary members 7 longitudinally relatively to the main member 6, so that the length of the platform may be increased or decreased, as may be desired.

Hinged to the outer terminals of the auxiliary members 7 are members 10 of the extensible legs 11. Two pairs of these members 10 are hinged to each of the auxiliary members 7 and between each pair of these members 10 there is a leg member 12, which is adapted to slide vertically relatively to the members 10. The leg members 12 are provided with bands 13, which are disposed around the members 10. As shown in Fig. 6 of the drawings, each of the leg members 12 has a vertical slot 14, through which is disposed a bolt 15, which projects through orifices in a band 16 secured around the lower terminals of the members 10. The bolts are provided with wing nuts 17, by means of which it is possible to draw together the sides of the lower terminals of the members 10 to clamp the members 12 in position after the platform 5 has been raised to the desired height. The lower terminals of the members 12 are connected by transverse members 18, to which are hinged members 19 of extensible braces 20, the members 19 of these extensible braces 20, which are two in number, one for each pair of legs, having secured to them, loop members 21 which are disposed around the other members 22 of the braces. The members 22 also have similar loop members 23 disposed around the members 19, these members 23 having threaded orifices through which are disposed screws 24-, which are adapted to press against the members 19 to hold them in position relatively to the members 22. As shown in Fig. 5 of the drawings, the members 22 of the extensible braces have threaded orifices in their upper terminals, which are adapted to register with orifices in lugs 25, pins or screw members 26 being disposed in these orifices to hold the members 22 in position relatively to the auxiliary members 7, to which the lugs are secured.

To the outer terminal of one of the auxiliary members 7 is hinged an extensible laddcr 2i", the members of this ladder being hing d to the end of the said auxiliary members 7 between the these members 28 being provided with loop members 29, which are disposed around companion ladder members 10, the loops having threaded orifices with screws 31., which are adapted to press against the members 30 to hold tl em in position relatively to the members 28. The members 30, at their upper ends, are provided with loop members 32, which are disposed around the members 28, shown in the drawings. Ladder rounds 3;) connect the members 30 and also the n'iembers 28.

To the ends of the main member 6 are hinged supports 3% and 85, the supports 34tbcing adapted to be raised to positions at right angles to the sides of the ends of the main member (3, the supports 35 being disposed obliquely in the direction of the supports Psi, to which they are secured attheir upper terminals. Hinged to the supports 34: are additional obliquely-disposed supports 36. Brace members 3? are also hinged to the supports the brace members 37 being disposed downwardly and having orifices in which are disposed screws 58, which mesh in threaded orifices in the sides of the main men'iber 6. A table is provided, having sockets ll) in which are disposed the upper terminals of the supports 3% and the obliquely-disposed supports 36, the upper terminals of these supports 3st and 36 having shoulders, which limit the downward movement of the table relatively to the supports. Under the table is disposed a rack 1-1, there being ropes or chains 42 which connect the rack with the bottom of the table, by which means the rack is supported.

To erect the scaffold the legs are disposed downwardly at right angles to the platform and the platform is raised to the desired height, the wing nuts 1.7 being unscrewed permitting the leg members 12 to remain stationary. When the platform 5 has been raised as desired, the wing nuts 17 are turned home, thereby clamping the leg members 12 relatively to the members 10 and furnishing a support for the platform. This having been done, the wing nuts Q l of the extensible bra "cs are unscrewed and the members are moved upwardly until the orifices in their upper terminals register with the orifices in the lugs which are secured. to the auxiliary members 7 of the table. This having been done, the pins 26 are in sorted in the orifices respectively, by which means the upper terminals of the extensible braces are secured in position, after which the wing screws 2:1- are turned home, holding the members 1!) and 22 of the extensible l'n'aces in position relatively to each other, by which means the 11. are braced. The wing screws 3]. of the ladder 27 are then unscrewed, freeing the members 30' and permitting them to descend. 'lhe ladder is then adjusted to the desired angle, with the lower terminals of the members 30 resting on the floor. The screws 31 are then turned home, the screws engaging the members 30 and holding them relatively to the members 28, the screws 31 being disposed in orilices in the bands 29, which are secured to the members 28 as has been described. The wm'kman then climbs up the ladder and raises the supports 34L and 35, bracing the supports 3-1- by means of the braces 37, the lower terminals of which are secured to the sides of the main member 6 by means of the screws 32:, which are disposed through orifices in the lower terminals of the braces 37, the screws meshing in the said orifices in the main member 6. The supports 34: and having been raised and the braces having been secured in position, the supports 36 are turned outwardly and the upper terminals of the supports 34- and 36 are disposed in the sockets of the table 39. The table will then be found to be in position where it may be used by the workman standing on the platform. Without readjusting the legs, or the table, it is possible for the workman to extend the platform merely by drawing out the auxiliary members 7.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:
