This inventioii relates to a;putlog ;em;- ployed in the erection ofbrick or inasonry walls, and particularly those of buildings.
"The invention has for its obj eat to prov de Fa novel andefiicient supporting device for the end of the putlog adjacent to the wall tion further has for its object to providea supporting device for the'putlog,
which enables the mason to work with ease v and at greater speed as will be described. 7 15 of the putlog as will be described. l 20 2'5 poi-ting device bears. I 0 l v These and other features of this nvention will be pointed out in the claims at the end of this specification. i

and easily applied to the putlog at The invention also has for its objectto enable the supporting'deviee to be attached p to. the putlog in close proximity to the end of the put-log without impair ng the strength The supporting-device for 'thepu'tlog is preferably constructed so that when attached to the 'endof the putlog, the upper surface 1 of the latter will be below the uppersurface 1 of the course of bricks upon which thegsupbuilding, a staging and putlogs porting. the staging, and supporting devices embodyvice shown in lfdetached from theput- R e r th dr w .0 pe enea putlo'g or piec'eof timber which is provided with a supporting device for its inner end.
The "supporting device, shown best in Figs.-
2 a ds; consists of a metal plate 12 provided at its rear end with a hub 13 mounted on the upper end-of a member capable of. being passed through the putlog and shown. as
a boltlel having a head 15 and provided-with a threaded loweren d 16, the headf l5over lapping the hub '13. The metal plate12 is preferablysecured in fixed relation to the bolt 14; which may be accomplished inany suitable manner, and in the'present instance is efiec'ted by punching a portion of the hub 18 into the' bolt as'repr'esented at 17 in Figs;
The 'inetal plate 12'will be hereinafter designated as the anchorplatefandisfmajde er.
a thickness substantially equal to space between adjacent bricks'18 inth same row or course of bricks in the-wall. T The anchor plate 12 is made'o'f length to' extend beyond the bricks of a rbw Or course and is provided atiits-fioiitl end with a finger 19 to engage abrick 20101 the vCourse of 2 (5 Fi P v il the bricks 18 are being laid.

the job, it only being necessary for the mason to bore a hole 27 through the putlog atsuch distance from the end oitheputlog as willallov'v; the recess 22 toproject beyond h sad i t elea her?eu fi ntdis an to afiord; amplej olearance for tilting theanchpr,

lVhen the hole 27 has been bored in the putlog, the boltor member 14 is passed therethrough until the'hub 13 of the anchor plate engages the put-log. The bolt is then turned until the anchor plate is axially arranged with respect to the putlog, shown in Figs. 3 and 4, and when thus positioned, the handle nut 25 is then applied to the bolt and turned up until it engages the under side of the putlog.
In this mannerthe putlog is provided with a supporting device for its inner end, which is in fixed relation to said putlog. The putlog is secured at its outer end by nails 30 or otherwise to vertical timbers 131 of the staging.
. The floor boards 31 are laid upon andsupported by the putlogs after the manner represented in Fig. 1. By reference to Fig. 3, it will be observed that the bearing surface 21 of the anchor plate which rests on the brick 20 in the uppermost row of laid bricks, is locatedin a plane above the lower end of the hub 13. of the anchor plate, and consequently the upper surface of the putlog is below the upper surface of, the uppermost course or row of laid bricks. As a result, the mason on the. staging oanquickly and easily trowel the mortar onto the uppermost course of laid bricks which are substantially on a level with the staging, and the necessity of reaching down over and below the staging to apply the mortar to the laid course of bricks is avoided.
Provision is made for enabling the anchor plate to be positioned at an angle to the lone gitudinal axis of the putlog and yet have sufficient of the recess 22 beyond the corner of the putlog toenable the anchor plateto be tilted without chipping or marring the edge of the brick upon which the anchor plate bears.
a second bore or hole 34 between the bore 27 and the end of the putlog, and located sufficiently near the endto obtain the desired projection of the recess 22 beyond the cornerof the putlog '(see Figs. .6 and 7), when the putlog is arranged at the corner of the building as represented in Fig. 1. The location of the second bore 34 nearerthe end of the putlog might weaken the putlog to such extent as to render it hazardous to use, and to avoid this, means are provided for reinforcing the putlog, said means consistin of a metal plate or bar 36 applied to the underside of the putlog and through one end of which is passed the bolt 14 and through the opposite end a second bolt 37, which difierent positions witlrrelation to the end 0f the putlog by rotating'the bolt 14.
' It will be observed that the supporting'device comprising the anchor plate 12, bolt 14 and handle nut 25, as well as the reinforcing device for the putlog comprising the plate 36, bolt 37 and nut 38, can be shipped to the job mounted on the putlog, or may be shipped to thejob separate from the putlog and used with any piece of Wood stock sultable for use as a putlog.
From the above description, it will be seen that the supporting device can be attached to the putlog in a minimum time and with a minimum of labor.
One embodiment of the invention is herein shown but it is not desired to limit the'invention to the particular construction shown.
JVhat is claimed is:
i 1. The combination with a putlog having a plurality of openings extended through it near the end thereof and spaced apart, a bolt extended through the opening nearest the end of the putlog, an anchor plate mounted on said bolt above the putlog and projecting beyond the latter, a reinforcing plate for the putlog through which said bolt is extended, a nut on said bolt co-operating with said re- 'inforcing plate, and a second bolt extended through an opening through the putlog removed from the end thereof, and through said reinforcing plate, and-a nut on said second bolt cooperating with the reinforcing plate.
2. The combination with a putlog having at one end thereof an opening extended through it, of a supporting device for said putlog comprising a bolt extended through saidopening, an anchor plate of substantial width provided with a hub mounted on said bolt above the putlog and of substantial- -l tht tb dtl dofthelat- To this end, the putlog 10 is provided with- Eng 0 plolec eyon 16 en ter, a reinforcing device for said putlog through which the said bolt is extended, a nut on said bolt co-operating with said reinforcing device, and additional means for securing said reinforcing device to said putlog at a point removed from the end thereof and beyond the said bolt. 7
3. The combination with a putlog having atone end an opening'extended through it, of a supporting device for said putlog comprising a bolt extended through said opening and ofa length to project above-the putlog a substantial distance and to project below said putlog, an anchor plate of substantial width'and provided with'a hub fast to the upper end of thebolt abovethe putlog to be moved with-the bolt when the latter is withdrawn from the opening in said putlog, and to have the lower end of the hub rest upon the 1 upper surface of the putlog when the anchor plate is in its operative position, said anchor plate in its operative position projecting bee 7 yond the end of the putlog between adjacent bricks of a course being laid to be supported by a brick of a laid course, and a handle nut engaging the lower end of the bolt below the putlog, said anchor plate, bolt and handle nut forming a unit capable of being shipped to the job as such;
I being of substantial length to project beyond 4:- A supporting device for a putlog comsubstantial width having a hub mounted upon the upper end of the bolt to rest upon the upper surface of theputlog and tobe moved with the bolt when the latter is disengaged from the putlog, said anchor plate the end of the putlog, and a nut on the lower end of the bolt for clamping the putlog between it and said anchor plate, said anchor plate being affixed to the upper end of the 7 bolt to be moved therewith as a unit and to I permit the portion of the bolt below the V anchor plate to be passed from the upper to the lower surface of the putlog with the anchor plate mounted on the said bol In testimony whereof, I have signed my name to this specification;
