SHINGLING-BRACKET.

Specification of Letters Patent.

Application filed January 22, 1909.

Patented Apr. 5, 1910. Serial No. 473,682.

To all lwhom it may concern:

Be it known that I, FRANCIS L. SPRING, a citizen of the United States, residing at Townsend, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Shingling- Brackets, of which the following is a specification.

This invention relates to an improved shingling bracket, and the object is to provide a light, strong bracket which may be adjusted to fit roofs of different pitches and which may be readily folded so as to occupy but little sp'ace; and the object is further to provide a bracket of this class, the base of which may be secured to the shingles by nails, and after a course of shingles has been laid on top of the base of the bracket the same may be readily disconnected from the nails without lifting the shingle which lies upon the base.

A still further object is to provide a strong and convenient device for securing to the bracket the adjustable stop against which rests the plank upon which the workmen sit. o

In the attainment of the objects above enumerated, I have produced a bracket which is simple in construction and economical to manufacture.

The invention consists in the novel features of construction and in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the appended claims.

Referring to the drawing: Figure 1 is a plan of a shingling bracket embodying my invention, the same being shown in place on the shingles of a roof. Fig. 2 is a sectional view taken on line 2 2 of Fig. 1. Fig. 3 is a side elevation of the bracket when folded. Like numerals refer to like parts throughout the several views of the drawing. In the drawing, is a base comprising two plates 6 and 7. To the plate 6 is secured a yoke 8, to which yoke a pair of arms 9, 9 are pivoted at 10, said arms terminating at their lower ends in spurs 11 adapted to stick into the/roof of the building. To the plate 7 is secured a bracket 12 to which bracket a pair of arms 13, 13 are pivoted at 14, said arms being pivoted at 15 to the rarms 9. The arms 13 are adapted to support the usual plank 16, said plank being held in position on said `arms by means of a stop 17 adjustably secured to said arms by means of a clamp screw or bolt 18' extending between said arms and through a clamp plate 19 located on the under side thereof, a thumb nut 2O having screwthreaded engagement with said screw being provided to coperate with said screw and clamp plate to secure'the stop 17 to the arms 13,.it bein understood that said stop may be adjuster longitudinally of said arms for differentwidths of planks. f

InY order that the arms 13 and planks 16 may be approximately horizontal regardless of the pitch of the roof the angle of the arms 9 and 13 to each other and to the base 5 may be varied by moving the plates 6 and 7 longitudinally of each other, said plates for lthat purpose being adjustably connected together preferably in the following manner. The plate 6 is provided with a series of holes 21, while the plate 7 is provided with a projection 22 formed thereon or secured thereto, which projection is adapted to enter any one of said series of holes. Embracing the plates 6 and 7 is a slide 23 which normally holds said plates against lateral displacement relatively to each other, said slide being adapted to -be moved from the position shown inA Fig. 2 toward the right out of engagement with the plate 6 and when said slide is thus disengaged the plate 6 may be lifted until the projection 22 passes out of the hole 21 in which it is located and said projection may then be placed in another hole of the series,V thus changing the length of the base 5 and consequently changing the angular relation of the arms 9 and 13 to each otherandcto said base, it being understood that thev slide 23 is again moved toward the left so as to embrace both of the plates. The plate 7 is provided adjacent to the free end thereof with two preferably V-shaped notches 24 and 25 extending thereinto from opposite edges, respectively, thereof, saidnotches being ,1o-- cated out of alinement -with each other longitudinally of said plate, said' plate being preferably narrowed vsomewhat at its right hand extremity.

In the use of the bracket, the workman, standing upon a scaffold at the side of the house, lays upon the roof several courses of shingles, the number shown in the drawing being tive. lle then places two or more of the brackets upon the courses of shingles thus laid, in the position shown and drives into the upper course of shingles two nails 26 and 27 in the notches 24s and 25, respectively, as shown in Fig. 1. These nails, when thus driven, prevent the bracket from sliding downwardly on the slope of the roof, the spurs 11 also tending to preventsuch sliding movement as well as preventing lateral movement of the bracket.

It will be noted that the arms 9, 9 diverge toward the lower ends thereof in such a manner as to give the bracket considerable rigidity laterally. The plank 16 is then laid upon the brackets in the usual manner and the workman sitting thereon then lays several more courses of shingle-s up on the slope of the roof as far as he can reach. After these new courses of shingles have been laid, other brackets are then put in place thereon in the manner hereinbefore described and subsequently the series of brackets previously used lower down on the roof are removed in the following manner. Each bracket is lifted slightly to disengage the spurs 11 from the shingles and said bracket is then swung laterally from the position shown in full lines in Fig. l to the position indicated in dotted lines therein so that the plate 7 may then be withdrawn from between the nails 26 and 27 and subsequently the workman strikes the shingle above said nails to drive them fully into the roof so that said shingle will lie in close Contact with the shingle therebeneatl'i.

Vhen it is so desired, the bracket may be conveniently folded so as to occupy but a small amount of space, this being accomplished by first loosening the stop 17 and moving the same from the position shown in Fig. 2 to a position adjacent to the pivot 14. The slide Q3 is then moved toward the right out of engagement with the plate 6 and said plate is then lifted until the projection 22 passes out of the hole 21 in which the same is located. The arms 13 are then swung in the direction of the arrow a, Fig. 2, through an angle of somewhat less than 900 and the plate 6 is then swung in the direction of the arrow Z) unt-il the same rest-s against the upper side of t-he arms 9. The arms 9 are then swung in the direction of the arrow c until they very nearly coincide with the plane of the arms 13. The arms 13 are then swung in the direction of the arrow CZ until the parts occupy the position shown in Fig. 3, the bracket when thus folded being very compact and occupying but a small amount of space.

Having thus described my invention,what I claim and desire by Letters Patent to secure is:
