2 Claims.

1 This invention relates to new and useful improvements and structural refinements in scaffolds,- particularly scaffolds such as are used by brick. layers, and the like, and the principal object of the invention: is to provide a scaffold structure which is of a highly versatile nature insofar that it may be assembled to suit any particular requirement, which, by virtue of its sturdiness, is very safe and dependable in operation, and which, by virtue of its discerptibility, may be quickly and easy erected or dismantled.

With the above more important objects and features in view and such other objects and features as may become apparent as this specifica tion proceeds, the invention consists essentially in the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the invention;

Figure 2 is a group perspective view of one of the supporting frames;

Figure 3 is an elevational view of a supporting frame, this being partially broken away so as to reveal its construction;

Figure 4 is a sectional detail, taken substantially in the plane of the line 4-4 in Figure 3;

Figure 5 is a sectional detail, taken substantially in the plane of the line 55 in Figure 3;

Figure 6 is a fragmentary top plan view showing the attachment of a supporting bracket to the supporting frame; and

Figure '7 is a group perspective view illustrating a modified cross piece and socket such as may be used in the invention.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the invention is embodied in a scaffold structure designated generally by the reference character ID, the same consisting of a plurality of spaced, vertical supporting frames, each designated generally by the reference character !2. Since these frames are similar in construction, it is believed that a description of one will suffice for all.

Each of the frames I2 consists of a pair of foot sockets I4 provided with aperture flanges l6 whereby they may be anchored to the ground or floor, the foot sockets I4 having fitted therein and secured by removable pins l8 a pair of lower uprights 20. It is to be noted that the sockets M are provided with inwardly projecting angle brackets 22 and a transverse tie rod 24 is attached by suitable fastening elements 25 to these brackets for securing the two foot sockets together.

A- pair of vertically elongated intermediate sockets 2B are provided with lateral openings 30 (see Figure 2) whereby they may be fitted on opposite end portions of a cross piece 32 to which they are secured by transverse pins 34, it being noted that the upper end portions of the lower uprights 20 are inserted in the lower end portions of the intermediate sockets 28. Similarly, lower end portions of upper uprights 35 are fitted into upper portions of the intermediate sockets 28, upper end portions of the upper uprights 36 being fitted into lower end portions of a pair of upper sockets 38 which are similar to the intermediate sockets 28 and are mounted by suitable elements 40 on opposite end portions of a second cross piece 42.

A transverse head piece M is rovided at the opposite ends thereof with a pair of inverted channels or extension plates 46 which are removably positioned on upper end portions of the two upper socketsv 38, this head piece being intended to support a horizontal board (not shown) at the top of the assembled scaffold.

It is to be observed that the sockets i4, 28, 38 are provided with inwardly projecting fastening elements 48 to receive upper and lower pairs of crossed tie rods 50 which extend diagonally between the sockets of adjacent supporting frames 12 at both sides of the scafiold, as is illustrated in Figure 1.

By virtue of this arrangement, the tie rods 50 not only substantially reinforce and connect together the several supporting frames l2, but by tying the several sockets of the frames together, the tie rods serve to retain the upper and lower portions of the

uprights

20, 36 in their respective sockets, so that the assembled unit assumes a rigid form.

If it is desired to support an additional board at one side of the scaffold, a supporting bracket designated generally by the reference character 52 may be applied to each of the frames i2, this bracket consisting of a vertical member or angle bar 54 which is rigidly secured at its upper end to an intermediate portion of a horizontal membe! or angle bar 56.

A diagonal brace 58 extends between the

members

54, 56, and a strap 50 is secured to the upper end of the member 54 to coact with the inner end portion of the member 56 in straddling the upper end portion of one of the upper sockets 38, so that a transverse keeper pin 62 may be inserted in the member 56 and the strap 60 for attaching the entire bracket to the associated frame. The pin 62 is disposed against the inner surface 64 of the associated upper socket under the adjacent channel 46 of the head piece 44 (see Figure 2), it being understood that sufficient space exists between the surface 64 and the adjacent end of the head piece 44 to accommodate the pin.

The outer end portion of the member 56 is provided with an upstanding lug 66 to prevent a board from sliding off the supporting bracket, and it is to be noted that a pair of spaced ears 68 are affixed to the lower end portion of the member 54 to straddle the adjacent upper upright 35, substantially as shown.

If it is desired to support a board at one sid of the scafiold, substantially at the level of the cross piece 32, one of the intermediate sockets 28 may be substituted by a socket 10 having open upper and lower ends to receive the

uprights

36, 20, respectively, while opposed lateral openings (one of which is shown at 12) in the socket l enable a relatively long cross piece 14 to be substituted for the cross piece 32 and extended laterally through the opening 12 of the socket 70 to project to one side of the scafiold. The position of the socket on the cross piece 14 is indicated by the dotted lines 76 in Figure 7,

It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and, accordingly, further description thereof at this point is deemed unnecessary. r 7

Having described the invention, what is claimed as new is:

1. In a scafiold structure supporting frame,- the combination of a pair of spaced uprights, vertically elongated sockets provided at the upper ends thereof, a cross piece having its ends fitted in and secured to intermediate portions of said sockets, and a removable transverse head piece provided at the ends thereof with inverted channels for positioning on upper portions of said sockets above said cross piece, a board supporting bracket disposed at one side of said frame and including a vertical'member provided at its lower end with a pair of spaced ears to receive one of said uprights therebetween, a horizontal member secured intermediate its ends to the upper end of the vertical member and affording an outwardly projecting arm and an inwardly projecting arm, and a horizontal strap secured to the upper end of said vertical member in spaced relation to said inwardly projecting arm whereby to receive an upper portion of one of said sockets therebetween, and a keeper pin extending through the inwardly projecting arm and said strap thereby engaging an inner surface of said socket, said transverse head piece comprising a means for retaining said pin against said inner surface.

2. In a scafiold structure, a supporting frame comprising a pair of spaced uprights, a pair of sockets having the upper ends of the uprights fitted in the lower ends thereof, said sockets having opposing aligned openings intermediate their ends, a cross piece extending between said sockets and having its ends extending through said openings and abutting the inner walls of said sockets remote from said openings, the upper ends of said uprights abutting the lower side edges of said cross piece, a transverse head member resting on said cross piece and having its ends terminating adjacent said sockets, a pair of inverted channel extension plates extending from opposite ends of said head member, said extension plates overlying and partially embracing the upper ends of said sockets to prevent movement of said head member with respect to said sockets.
