it is-l'customary 10:11:89 transversepins or similar devices tor holding' the legs of a tfres tleto a transversesupporting bar or tie membersbetweenth' legs, or both, acting to prevent the legs, "om separating incident to :the .weight upon thefltransver'se 'b'ar. Some constructions use soclietj membersftor" the vlegs, the socket members vbeing also tastene d: to vthe transverse bar with anti-spread ing means between j the eeker; members (which receive the legs), ftliereby' preventing the; socket .members from separating. These constructions are weak and'it isnecessary to retain the various parts of the trestle assembledatall times, rendering it very inconvenient for the trestle to be portable from one place to another.
The present invention has for its purpose to provide a socket member for scafiold trestles which does away with holding pins, screws and anti-spreading devices and yet at'the same time enable the legs to be easily and very quickly disassembled from the socket member, allowingthe variousparts of the trestle to be arranged in a small compass either for storage or for transportation from one place to another.
' It is another purpose to provide a socket member for scafi'old trestles which may be constructed of relativelyheavy sheet steel or in the form of castings and which are substantial in every respect and at the same time will prevent spreading of the legs of the trestle, it being possible to disassemble the two members of each socket member and remove the transverse bar'and the legs, al-
lowing the various parts to be transported in small compass. 1
It is to be understood that the particulars herein given are in no way limitative and that. while still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to the circumstances.
The invention comprises further'features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed. I
In the drawings:
Figure 1 is a view in perspective of one end of a scaffold trestle, showing the improved socket member as applied and'constructed in accordance with the invention.
Figure 2' is a. vertical sectional view on line 2-2of Figure 1.
' Eigur'e 3 is a'transverse sectionalview on i I nine 3'3 of Figure 2 7 V v Figure 1s a detail view ,in' perspective of thei ner member of each socket member,
and
Figure 5 is a detail viewin perspective of the outer inembe'n- I Referring to the drawings, 1 designates a crossbar of a trestle and 2 d'en0te socket members, one for'eachend ofthe cross Each socket mbe may be eonstructeii' in any proportions and shape and may be made of suitable sheet s'teelfor' in .the foiin ofeastings. Each socket membereomprisesan in walls are end walls 6 which are notched or recessed, as shown at 7, for the reception of the ends of the cross bar or beam 1. The lower portions 8 of the end walls assist in withstanding the weight of the cross bar or beam and such work as may be supported thereby.
net: shell and an outer'sh 1l,the1atiter fitting The outer shell or section also comprises side walls 9 which converge upwardl corresponding to the walls 4 but it will be noted that the outer shell or section iswider, that is, from one wall 9 to the opposite wall 9, than the inner section or shell thereby causing to be formed leg receiving sockets 10; In this way, the le s 11 diverge downwardly. The outer section or shell also has end walls 12 somewhat similarto those of the inner section or shell and are recessed at 13. 1 I
The recesses 13 are of the same proportions as the recesses 7 of the inner section or shell and register therewith and also receive the ends of the cross bar or beam 1. The lower portions 14 of the end walls register with the lower portions 8 of the inner section or shell and assist the portions 8 in withstanding the weightof the cross bar or beam and such workas may be supported thereon. i v
v The end walls of the inner and outer sections are riveted or otherwise secured toloo than the inner section or shell in that it has a top wall 17 which overlies the upper edge of the beam or bar 1 and also cooperates with the lateral extensions or flanges 5 to withstand the pressure of the upper ends of the legs while engaged in their sockets.
Upon examination of the above in connection with the drawings, it will be understood that the operator, when through using the trestle, may remove the legs from the sockets, withdraw the cross bar or beam, and then the several parts may be arranged close together in small compass, allowing the parts to be easily t 'ansported from one place to another without any inconvenience, such as would be the case it the trestle remained sembled.
It will be noted by this construction of socket member for scafi'old trestles that nails, screws, braces such as tie chains and tie rods, and like devices are entirely eliminated. This construction of socket member for trestles enables the workman to very quickly and easily assemble the parts when the same are to be used, it being noticed that they may be disassembled with equal facility.
The invention having been set forth, what is claimed is:
In a scaffold trestle, a transverse work supporting beam and supporting legs asso ciated therewith and downwardly divergent therefrom, a casing removably connected to the end of the beam and provided with spaced sockets corresponding divergently with the legs and adapted to removably re ceive their upper ends, said casing consisting of inner and outer sections, and means for fastening the sections together, one within the other, the inner side walls of the sockets having at their upper ends lateral extensions or flanges which, together with the top walls of the outer section, resist the ressure of the upper ends of the legs, w ereby the trestle may withstand the weight of the work resting thereon.
In testimony whereof he aifixes his signature.
