To all whom it may concern.'

Be it known that I, HOWARD O. MCMIL- LAN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Shore and Trench Braces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will .enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a timber support or shore such as commonly used in building construction. It is desirable to have a shore which firmly supports and holds the timber' vand it is very desirable to have a shore which can be adjusted so that the timber supporting part can be raised any distance desired relatively to the standard.

.It is an object of this invention, therefore, to provide a shore comprising a standard and a timber supporting member movable relatively thereto, together with means for moving said timber supporting member any distance desired along the standard, which shore also has a high degree of utility when used as a trench brace.

It is a further object of the invention to provide ashore, as set forth in the preceding paragraph,`in which the standard also has means adjacent its top for4 clamping the supported' timber.

It is still another object of the invention to-provide a shore havin a standard with a timber supporting brac et slidable thereon, together with means adapted to pass transversely through the bracket and standard for raising and holding said bracket in the desired position. j

It is still another object ofthe invention to provide a shore, as set forth in the preceding paragraph, in which the standard has V a series of spaced slots therein and said bracket has a plurality of slots. therethrough spaced a different distance apart than the slots in said standard, said 'means comprisv ing a pair of wedges adaptedto be ldriven through the slots in said bracket 'and standard and relatively move said parts.

These and other ob'ects and advantages of the invention willv efully'set forth in ythe following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the diierent views,'

and in which,

Fig. 1 isa view'in front elevation of the shore showmg a portion of a timbersupported thereby;

Fig.'2 1s a view in side elevation, as seen from the right of Fig.1';

Fig. 3 is a top plan view of the device Fig. 4 is a transverse section on the line 4 1 of Fig.'2 as indicated by the arrows;

Fig. 52 is a view similar to Fig. 3, showing a modification; and

Fig. 64 is a view in side elevation of Fig. 5. 'Referring to the drawings, a shore is shown comprising av standard 5. While this standard may be made ofv various forms, or shapes, in the lembodiment of the invention illustrated, the same is shown as formed of a T-bar having a lower end extending substantially at right angles. to its `length to which is connected a foot 5"' compri'sin a flat platehaving upstanding ears 5b em racing the main arm or web 5c of the 'standard 5 and beingv connected thereto by a suitable rivet, one side of the ears 5h being disposed ad'- jacent the cross arms 5d of the standard. A.

timber supporting bracket 6 is'provided having a main portion with a T-shaped slot 6'L therein adapted to fit over the standard 5 lso that the bracket is slidable thereon and has Iflat sides embracing the main arm or web 5c'of the standard.' The bracket 6 has a plate 6b extending outwardly of its top substantially at right angles to the face vof the crossarms 5d of the standard, which plate hasan upwardly projecting fin 6c at its outer edge. A central triangular rib 6 is shown-as connecting the plate 6b to themain portion of the bracket and said vplate 6" has a plurality of hole-s .6 therethrough adaptedto receive nails or spikes 7-driven therethrough upwardly into the bottoni of the timber 9 which is supported upon plate 6". The main web 5" of the standard 5' is provided with a plurality of elonvated spaced slots 5 extending therethrough s own as rectangular in shape and alined longitudinally of said standard. The sides-of bracket 6 at each side 'of web '5c are provided with a plurality of similarly shaped slots 6 cen-` 'trally alined with the slots buty spaced a different distance apart than' the slots 5. In the embodiment of the invention illustrated, theslots 6t are shown as s .aced farther apart .than the slots 5. A pair of wedges 8' are provided adapted to extend through the slots 5e and 6', as clearly shown in-Figs. 1, 2 and 4, said wedges being shown as having small i square apertures 8 extending therethrough 'wrenches to turn said screws.

adjacent their longer ends. Pairs of lugs 6 and 6g are provided at one side of brackets 6 between which wedges 8 move, the lugs Gf being threaded to receive set screws 12. The holes 8a are made to lit overthe heads of screws 12 so that the wedges'8 constitute The standard i has secured thereto adjacent its top, a yoke 10 andwhile'this yoke may be variously formed, in the embodiment of the invention illustrated, it is shown as formed of a flat bar havingits ends disposed at eachl side of web 5c and riveted thereto, the sides of said yoke extending outwardly at each side' ot said web closely. adjacent the cross arms 5" and parallel to and bevond the latter. The

sides of the yoke are then extended outwardly parallel to each other and at right angles to the front of the standard 5, the sides being joined by an end portion l()n extending at Aan acute angle to said sides. The sides of theY yoke 10 "adjacent the end 10 are provided ...with alined elongated slots 10b adapted to re- In the modification shown in Fig. 6 a different form of yoke is shown to be used inl place of yoke 10. Angle pieces 13 are provided villustrated as made from a short piece of flat bar bent at right angles, said members .being'disposed against opposite sides of web 5p and riveted thereto sof that the bent portions projectoutwardly and oppositely at right angles to said web. Strips or plates 14 and l15 also made from flat bars are riveted at either side of the members 13 and project forwardly at both sides of the front of the standard 5, plates 14 and 15 being secured at their outer ends; to a strip or plate 16 riveted between the plates 14 and extending to and rivetedl between the vplates 15, said plates 16 extending. at an angle to the front face of standard 5. The plates 14 and 15 also extend at each side of the timber 9 and the wedge 11 can be driven into place between plates 14' and 1'5 and with its inclined side enga ing the edge of plate l6.` The other sideo the wedge 11 engages the tace ot timber 9 so that said timber is tightlydclamped in position against the standar 5. n In the use of the device asa shore the same will be brought adjacent the timber 9l to be supported and the flat bottom end of said timber will be engaged with the'l top yof plate 6b, the timber being disposed within and held from outward movement at its lower end by the tin 6. The timber can be held against lateral movement by driving the spikes 7 into the bottom thereof through the holes 6e. It is unnecessary, therefore, to lit the bottom ofthe timber between any parts or flanges at its sides. `The timber 9 -will pass through the yoke 10. In order to support the bracket 6, one of the wedges 8 will pass through a pair of slots 6t in the bracket and through one of the slots 5c in the standard. If it is desired to raise the timber 9 the wedge 8 will be driven through the bracket 6 and web 5c of lthe standard j and the successive movements of the wedge resulting from the blows thereon will gradually raise the bracket 6 and timber 9. When j the wedge 8 has been driven in place to" its widest part, another slot 5c will be brought into partial alinement with the other pair of slots 6t and the other wedge 8 can then be inserted through these partially alined slotsand driven through the brackets and standard. The brackety 6 will be raised as this wedge is successively driven intol place and when the wide part of the wedge has been driven into the bracket 6 another slot 5 will be partially brought into alinement with the lirst mentioned pair ot slots Gf so that the wedge iirst used can again be inserted and -driven into place. It is thus possible by the successive use of the wedges 8 to raise the bracket 6 and move the same along the standard 5 any desired distance, The bracket 6 can be moved throughout substantially the whole length of the standard 5. The bracket 6 can'be raised with the :rod or timber 9 thereon and it is unnecessary to make any adjustment of the bracket 6 and standard 5 4or to change the relative position before using the next wedge 8. The bracket 6 can be continuously moved by the successive use of the wedges without any retrograde movement ot the bracket 6. The wedges 8 not only act to raise the bracket means but also form a holding means for holding the same in desired position. While the wedges 8 bind against the ends of slots in bracket 8 and web 5, and are securely held in place, the set screws 12 are provided by means of which the wedges can be securely locked in position, if desired. The set screws 12 can readily be turned by using one of the wedges 8 as a wrench. After the timber 9 is brought to the desired position, the wedge 11 is inserted into slots 10b with its inclined side in engagement `with the inclined end 10l of the yoke 10 and the wedge then driven tightly into position. The wedge 11 will act to irmly clamp the timber 9 between the same and the front of standard 5 so that'the tim'- ber isheld very securely in position. The timber does not have to be dressed to exactly fit the yoke. Pins 11b and tongues 11c prevent the wedges 11 from being removed lool"A The 'operation of form of oke shown in Fig. 5 is Vsimilar to that of yo e 10 and it is thought .no further description thereof will be necessary.

When the device is used as a trench brace the saine will extend transversely across the trench at right an les to the sides thereof, the brace 5% will e placedviat against a board 'at one side of the trench. A block similar to the short length ofA the timber 9 illustrated will now be placed through the yoke 10 and against the plate 6", said block being of sulicient length to extend beyond the yoke 10. The outer end yof this block can now be engaged with a board at the lside of the trench opposite that at whiclithe brace 52L is disposed. The block can then be moved by the bracket 6 by the use of the wedges, as above described. The sides of the trench can thus be effectively braced and the boards at the side of the trench can be pressed apart asis desired.

From the above' description it is seen that applicant has provided a very simple and efficient adjustable shore and trenchv brace. When used as ashore, the device, as described, can be easily and quickly laced in position and the timber supporte out any re-setting of the bracket 6. The

device is easily and inexpensively made and can be made very rugged so that it will be quite durable.

It will, of course, be understood," that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objectsNabove set forth, in the novel parts and combinations of parts disclosed and defined in the appended claims. v What is claimed is: v
