SPECIFICATION forming part of Letters Patent No. 788,899, dated. May 2, 1905.

Application filed January 28, 1905. Serial No. 243,093.

.To al?, 'whom it nmy/ concern:

`United States, residing in Amesbury, in the county of Essex and State ot' Massachusetts,

'have'invented eertainnew and useful Improvements in Oarpenterr Brackets, of which the following is a speeilication.

This invention relates to carpenters brackets adapted to be applied to the outside wall ol a building' for supporting a plank, stage, or other article or structure on which the earpenter or other workman may stand while at work on the building.

The invention has 'for its particular object to provide a construction whereby the bracket may be applied to the outer wall of a building withoutinterfering with, marring,or puncturing the plastering or lathing on the inner wall.

The nature of the invention is fully described below and illustrated in the accompanying drawings, in which Figure 1 is a transverse vertical section otl a portion of a building-walLincluding the outer wall. the stud, the laths, and the plaster, said wall being prepared for the application ot' our improved bracket, and a view in side elevation oi' our improved bracket in position for being applied tothe wall. Fig. 2 is an enlarged vertical section taken through the wall and a portion ot' the bracket, the bracket being illustrated as locked in position. Fig. 3 is a plan View of the inner end ol the locking mechanism removed.

Similar letters ot' reference indicate correspending parts.

a, represents the horizontal or supporting portion ol the bracket, the upright portion, which rests against the wall, and c the base.

d and I are respectively the outer and inner walls of a building', the outer wall (l being provided with a horizontal hole j', whereby our bracket may be applied.

represents a socket or tubular ease preterably closed at its front end by a plug or equivalent device 7i, and open at its rear end. One ot the side walls of this case is provided with a horizontal slot L', from which a slot Z extends at right angles down tothe bottoni et' the case, said slot being such as is used in an ordinary lantern-joint. A bolt n lies in this tubular case or socket, and a short arm p extends radially from said bolt through the right-angled slot fl and is provided on its outer end with a suitable handle or ball fr. From the inner end of this tube or socket there extends horizontally two parallel ears s, whose planes are on vertical lines, and the inner end n of` the bolt is flat and on a vertical plane.

z5 represents a latch pivotally secured at a to and between the ears s, the upper or inner end t of said latch being `fiat and at right angles with its sides and the outer end t being' preferably rounded olii' or curved, as shown. The tube or ease f/ is supported against the under sideot1 the part t of the bracket by means of one or more bolts n, which extend through said part a and suitable holes w, 'formed in the case g and plug 71 and are provided with suitable nuts w, and the case, furthermore, extends through a horizontal hole in the upright portion By this means it is held lirmly in a horizontal position and may be adjusted horizontally as desired.

ln operation when it is desired to securely and rigidly apply the bracket to the wall a hole j' is irst made in the outer wall, said hole being in such a position as to be acccssi ble from a window, ladder, or other structure. 'lhe carpenter places the bracket with the parts in the position indicated in Fig. A1 that is, with the arm p swung down through the slot l and with the latch in a horizontal position and held therein by the outer ilatend fn. ot' the bolt u., which rests against the fiat end i!" of' the latch The bracket is then placed opposite the hole f and moved toward the build ing and the latch inserted in the hole, the inner end ot' the tube extending' for a suflicient distance beyond the upright portion ot' the bracket to reach entirely through the hole f and the length of the latch t being less than the width ot' the space between the outer and inner walls Il f. VIn theory the carpenter should then reach down and swing the arm p up from the slot into the slot s, thus allowing the latch t to drop; but in practice the ordinary jar produced by placing the bracket in position against the wall is such that the arm p is loosened and swings up from the slot Z into the slot r by reason of the Weight of the latch t, Which swings down and forces slightly back the bolt a. The carpenter, therefore, in practice reaches forv the bolt p, which he finds disengaged from the slot Z, and pushes it down into the vertical position shown in Fig. 2 in said slot Z. Thus the latch is locked in the position indicated in Fig. 2 against the inner surface of the outer Wall, being held in such locked position by the outer end n of the bolt n., which bears against the rear portion of the Hat bottom of the latch t.

As will be readily seen from the above description, the workman needs but one hand with Which to adjust the locking device, so that his other hand is free to hold himself safely in position, as in a Window, for eX- ample.

ln practice We may sli ghtl y-vary the height of the lantern-joint, more particularly7 the slot 7c, making it as near the extreme bottom of the tubular case as practicable.

The curved end of the latch facilitates its entrance into the hole f.

Having thus fully described our invention, what We claim, and desire to secure by Letters Patent, is-

1. In a device of the character described, a a bracket; a tubular case or socket supported substantially horizontally by the bracket; a bolt adapted to slide in said tubular case; a

latch pivotally secured to the outer end of the tubular case, the adjacent ends of the bolt and latch being substantially parallel 'v'vhen the latch is in horizontal line With the bolt, and means for locking the bolt with its end against either the end or bottom of the latch, for the purpose set forth.

2. In a device of the character described, a bracket; the tubular case or socket g secured substantially horizontally to the bracket; the bolt a sliding in said tubular case and provided With the squared end n; the latch t pivotally secured to the end of the tubular case and having the squared end f; and means for sliding the bolt in the case and locking it thereto, for the purpose set forth.

3. In a device of the character described, a bracket; the tubular case or socket g provided With the lantern-joint slot-s Zt, Z, and secured to the bracket with its outer end projecting beyond the back of the bracket; the bolt a sliding in said bracket; the arm p eX- tending from the bolt through said slots; and the latch f hinged to the end of the bolt, and adapted to be held in line therewith or at right angles thereto by sliding the bolt in opposite directions, for the purpose set forth.

In testimony whereof We have signed our names to this specification in the` presence of two subscribing Witnesses.
