PUTLOG SUPPORTING CLIP Filed March 12, 1948 ATTUF/VE) Patented Jan. 24, 1950 UNITED "STATES PATENT OFFICE Eivind B. Christoffersen, Ogema, Wis.

Application March 12, 1948, Serial No. 14,415

This invention relates to an improved construction of putlog supporting clip for use in erecting scaffolding for masonry work and is especially intended to replace the customary methods of giving the putlogs a four inch bearing on the masonry wall making it necessary to cut blocks or bricks around the putlog when laying up the wall and subsequently requiring filling in the holes left by the putlogs in the wall after reeputlo'gs capable of beingformed from two 2 x 4s and having an extension or lug for bearing on the masonry wall and which is so constructed that it may be readily removed from the'wall when the scaffold is torn down and which will leave only a small. space between courses of the bricks or blocks and whichmay be readily filled-in with ,mortar or other bonding mediums.

Another object of the invention is to provide a novel putlog supporting clip having means to prevent the planks forming the platform of the scaffold from extending too close to the wall and so as to interfere with the masons work and which will also insure a sufficient space between the wall and scaffold platform to permit mortar droppings to fall therebetween.

Another object of the invention is to provide a clip which will afford sufiicient spacing between the scaffold platform and wall to afford ample room to reach the bed joints for tooling and which will position the platform so that the masons shoes will be disposed above the bed joints to prevent scufling the joint while laying the wall.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description. of the drawing, illustrating a presently preferred embodiment thereof, and wherein:

Figure 1 is an elevational view showing an erected scaffold partially supported by the putlog clips applied to the bed joint of a wall;

Figure 2 is a view in elevation looking from right to left of Figure 1;

Figure 3 is an enlarged vertical sectional view taken substantially along a plane as indicated by the line 3-3 of Figure 1;

Figure 4 is a top plan view of the putlog supp t n clip;

Figure 5 is an end elevational view thereof looking from left to right of Figure 4, and

2 Claims. (Cl. 304-39) Figure 6 is a perspective view of the putlog clip.

Referring more specifically to the drawing, for the purpose of illustrating a preferred application and use of the putlog clip comprising the invention and which is designated generally I, the numeral 8 generally designates a partially erected wall formed of bricks or blocks connected by mortar or other suitable bonding medium and the numeral 9 generally designates a scaffold including spaced putlogs I0 the corresponding ends'of which are supported by a frame member ll of the scaffold and the opposite ends of which are supported on the bed joint !2 of the wall 3 each by a putlog clip I. The scaffold 9 also includes a platform l3 formed of planks and which are supported on the putlogs ID.

The putlog clip 1 may be made in various sizes but for most practical purposes is sized to receive and snugly fit a 4 x 4 putlog and will be 50 described although it is to be understood that variations in size may be resorted to and are contemplated. The putlog clip 1 includes an elongated relatively heavy plate, designated generally l4 having an upright intermediate portion l5 and substantially parallel bottom and top portions l6 and I! which extend in opposite directions in the upper and lower ends of the intermediate portion IS. The clip I also includes a plate, designated generally 25 having corresponding side portions I8 provided with inclined forward edges l9 forming restricted forward extensions which are secured to the side edges of the portion l5 as by welding as seen at 20. Said inclined edges I9 also form restricted lower portions of the side walls l8 and said portions, designated 2|, are turned inwardly to engage the underside of the bottom clip portion l6 and are secured thereto by welding, as seen at 22. The top wall of the plate 25 is disposed substan tially parallel to the clip portion l5 and is cut out at its inner or forward end to provide an upturned tongue 23 which is disposed adjacent to and substantially parallel to the clip portion l5.

Said portions I6, l8 and the top wall formed by the plate 25 combine to form a socket adapted to receive an end of the putlog l0 and each of said side walls I8 is provided with an opening 24 for receiving a driven fastening to detachably secure a putlog therein.

The portion ll constitutes a lug which is adapted to rest on the bed joint [2 of the wall 3 and which tapers in width as clearly illustrated in Figures 4 and 6 toward its outer end. The inner end wall l5 of the putlog clip I will bear against one side of the wall 8 when the lug ll is disposed on the bed joint, as best illustrated in Figure 3 and it will be readily apparent that the superimposed courses of the bricks or blocks will be laid above the lug l l which will be disposed in a portion of the mortar joint. The upstanding tongue 23 which extends to above the level of the lug ll forms a stop for the platform l3 to hold the inner edge of said platform a predetermined distance from the adjacent surface of the wall 8 so that droppings of mortar can fall through the space thus provided and it will not collect on the platform. The tongue 23 also positions the inner end of the platform 13 above the level of the bed joint I2 so that said joint will not be scuffed by the masons shoes and insures ample space for reaching the bed joint I2 for properly tooling the same.

The putlog clip 7 enables the use of two 2 X PS to form each 4 X 4 putlog it], as seen in Figure 1, and with said 2 x 4s having their vertical surfaces abutting. Thus, by the use of the clip 7 it is possible to utilize 2 X 4s which are always available around a construction job where 4 x 4s are frequently not available and Without in any way reducing the strength of the scaffold and Without damaging the 2 X ls so that they can be initially used in forming the concrete foundation of a structure, thereafter used in pairs to form the putlogs and after the scaffold is taken down the same 2 X 4s may be utilized in the framing of the building or for joists or partitions, thus substantially eliminating any expense in loss of material in the scaffolding or in transportation thereof.

The tapered shape of the lug I7 is to enable it to be readily slid out of the bed joint when the scafiolding is being taken down and the recess left thereby may be readily filled with mortar and without adversely affecting the appearance or strength of the wall.

Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.

I claim as my invention:

1. A putlog clip comprising a socket having an open outer end adapted to receive the end of a putlog, said clip having a lug formed integral with a portion of said socket and projecting from the opposite inner end thereof in the opposite direction to said socket and adapted to rest on the bed joint of a wall for supporting the clip thereon and with said socket. portion disposed at substantially a right angle to the plane of the wall, said socket having an upturned tongue spaced from the inner end thereof and adapted to engage an edge of a platform supported by the putlog for spacing the platform from the adjacent face of the Wall.

2. A putlog clip comprising a socket having an open outer end adapted to receive the end of a putlog, said clip having a lug formed integral with a portion of said socket and projecting from the opposite inner end thereof in the opposite direction to said socket and adapted to rest on the bed joint of a Wall for supporting the clip thereon and With said socket portion disposed at substantially a right angle to the plane of the wall, said socket having an upturned tongue spaced from the inner end thereof and adapted to engage an edge of a platform supported by the putlog for spacing the platform from the adjacent face of the wall, and the top wall of said socket forming a support for a part of said platform for positioning the platform above the level of said lug and the bed joint of the wall engaged thereby.
