S H 0 R] N G SPECIFICATION forming part of Letters Patent No. 613,517, dated November 1, 1898.

Application filed March 14, 1898- Serial No. 673,882. (No model.)

To all whom it may concern:

Be it known that I, WALTER G. J ONES, a citizen of the United States, residing at Manhattan borough, New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shoring; 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 that system of props or supports for carrying and sustaining the Walls of buildings and other structures which have been deprived of their structural supports or weakened by excavations carried on in their immediate neighborhood. This system of temporary supports is usually known as shoring, and it consists of horizontal beams passed through openings made in the walls requiring support that carry the weight of the walls, props placed at more or less inclination under the outer ends of the beams, while the inner ends of the beams,which extend inside the structure, rest on the floors of the apartments, it being necessary in most cases to strengthen the floors to enable them to sustain the weight. This system of shoring is efficient, so far as aifording a safe and secure support for weakened walls, but there are some serious objections to the system owing to the necessity of entering the rooms of the building and supporting the ends of the beams therein, this being frequently objected to by the tenants, sometimes not permitted, and always entailing expense and trouble on the contractor or the party for whom the work is done.

The object of my invention is to contrive a system of shoring that will obviate the obj ections to the system heretofore in use by doing away with the necessity of carrying any part of the shoring inside of the Walls of the part of the building supported by the shoring; and a further object of the invention is to utilize the weight of the supported shored-up walls to steady and sustain the shoring appliances in position and maintain the walls in plumb.

To this end the invention consists, first, in a system of shoring by which the downward thrust of the shored-up walls exerted upon the ends of beams and the props that support the said beams is counteracted by the upward pull of the opposite ends of the beams on the props through connections between the ends of the beams and sills on which the said props stand.

The invention further consists in shoring for buildings and other structures comprising beams, props, and sills arranged so that the beams support the walls on their inner ends only and are held in position by connecting their outer ends with the sills on which the props that support the beams stand.

In the accompanying drawings, Figure 1 represents a perspective View of the front wall of a building from which the lower wall has been taken out preparatory to putting a beam in to support the upper wall and showing the upper wall temporarily supported by my improved system. Fig. 2 is a sectional side elevation of the same wall and the shoring, showing the upper supporting-beam passed partly through the wall. Fig. 3 represents a sectional side elevation of a building having the structural supports for the walls removed and the walls shored up by my improved system,

and also illustrating the mode of strengthening the floor of the apartment from which the walls have been taken out to enable them to support the pressure of the member of the shoring system resting on that floor. Fig. 4 represents a sectional side elevation of a building from which the structuralsupports of the walls have been removed and showing a system of outside shoring on the principle of my invention. Fig. 5 is a front elevation, and Fig. 6 a sectional side elevation of a wall and 'a modified construction of the shoring.

Referring to the drawings, A designates the front wall of a building from which the under part has been removed for the purpose of reconstructing the lower story. The removal of the underpinning takes away the structural support of the upper wall, and this renders a temporary support necessary. My improved system of shoring is shown applied to the support of this wall, and I will now proceed to describe its construction and the mode of applying it.

The shoring consists of a number of wallbeams B B, &c., (the number depending partly upon the width of the wall to be supported and partly upon the weight the beams are required to carry,) a corresponding number of sills D D, &c., a post orpropE for each pair of wall-beams and sills, upper and lower yoke-beams F F, and tie-rods G G, &c., or their equivalent, which connect the upper and lower yoke-beams. The wall-beams B may be built-up beams of steel, as shown, or they may be made of wood, if preferred. The sills are preferably made of wood and have foot-plates a let in their upper sides to give a firm and durable bearing for the screw-jacks b on the ends of the posts or props E. The posts or props are square timbers fitted with the screw-jacks at their lower ends to adapt them to lift the wall-beams and adjust them vertically to bear against the upper sides of the openings in the wall. The yokes are preferably made of built-up beams, and the tierods are fitted with turnbuckles d and have at their extremities an eye 6, through which to pass a barf to hold the rods in the yokebeams, or, if preferred, their ends may be passed through a plate 9 and upset to form a head h to hold the plate on the rod.

The several members of the shoring thus described are to be made of the best material which experience has shown to be suitable for the purpose, and while I have mentioned the material to be used and also their construction yet I do not restrict myself in these respects, but propose to substitute other materials and change the construction of the parts should experience make it necessary to do so.

To apply this shoring to support the walls of the building, I proceed as follows: Openings H are made in the wall at the proper height to enable the part which is to be altered to be removed to receive the ends of the wall-beams B; but instead of making these openings entirely through the walls, as heretofore, they may extend but little more than half-way through, as in Fig. 2, or at the utmost not farther than the inner face of the wall, as shown in Fig. 3. The ends of the beams are inserted in the holes and the vertical props E are placed under the beams, the screw-jacks on the lower ends of the props standing on the plates a on the sills D, which are placed in position in vertical alinement with the wall-beams B, as shown. The yokebeams F F are then placed in position, the former over the outer ends of the wall-beams B B and the latter under the outer ends of the sills D D, and the upper and lower yokebeams are connected together by the tie-rods G G. By means of the screw-jacks the props are made to lift the wall-beams B B until their inner ends bear firmly against the upper sides of the openings II II in the'wall, so that when the structural supports of the Wall are removed the upper wall will be supported by the beams without appreciable settling. Simultaneously with the adjustment of the beams by means of the props and the screwjacks the upper yoke F is made to hold the outer ends of the wall-beams down and keep the beams level by means of the tie-rods and turnbuckles. When the structural supports are taken out, the wall rests on the inner ends of the wall-beams, the sills are held down by the props, and the weight of the wall and the outer ends of the wall-beams are held by the yoke F, tie-rods G, and the yoke F under the ends of the sills, the weight of the wall being thus utilized to support itself by means of the cooperation of the several members of the shoring system.

By this system of shoring it will be seen that the parts of the building which are not undergoing reconstruction are entirely undisturbed, as none of the shoring is carried inside the walls, but the work is confined entirely to the exterior so far as the parts of the building above the part removed are concerned.

Fig. 3 shows the means adopted for strengthening the floor under the sills when the shoring up is done from the level of the groundfloor of the building. The sill rests upon blocks I I, the former placed on the floor of the building and the latter outside on the pavement P, so that the sill is perfectly level. Directly under the block I the floor is supported by a prop K, standing in a suitable base on the floor of the cellar. It will be understood that under each of the sills a simi lar prop is placed to support the floor.

Fig. 4 represents a mode of using my sys* tem by which the shoring up is done entirely outside of the building, which is particularly applicable to those cases Where there is a vault under the pavement. In this case the inner ends of the sills are inserted in holes 2', made in the cellar-walls L, and the sills are otherwise supported on blocks, resting on the floor of the vault V. Thus arranged the shoring does not disturb the interior of the building.

The modification illustrated by Figs. 5 and and 6 relates to the connections between the outer ends of the wall-beams and the sills. The yoke-beams in this case are dispensed with and connection is made between each wall-beam and its companion sill. The connections consist of two beams M M, put together so as to leave a slot Z between and having at the top and bottom loops 1) p, riveted to the sides of the beams, so that a space is left, and the ends of the wall-beams and sills are inserted in the loops. The extremities of the wall-beams are reduced to form tongues g, which are no thicker than the slots Z between the beams, so that they will pass down in the slots. The ends of the beams being inserted in the loop 1) wedges N are driven in between the ends of the wall-beams and the top of the loops to fasten the ends of the beams in the loops and to hold them firm and level when the weight of the wall falls upon the opposite ends of the beams.

I claim 1. An improved system of shoring consisting of a beam and a sill, a connection between their outer ends and a prop holding them apart at some intermediate point of their length, the weight of the part of the wall to be supported resting upon the free end of the beam while the free end of the sill rests upon a suitable support, the beam and sill thus operate as levers on the respective ends of the prop as fulcrumsthe downward pressure on'the free end of the beam and the upward pressure on the free end of the sill creating a tendency of the connected ends of the same to separate, which tendency is counteracted by the connections between the ends,

substantially as specified.

2. The combination in a shoring apparatus of beams for supporting the walls, props placed under the said beams at a suitable point between the walls and the outer ends of the beams, sills on which the said props stand, and connections between the outer ends of the beams, and the ends of the sills, substantially as specified.

3. The combination with the walls of a building of a plurality of beams having their 25 sills placed under the props, and connections 30 between the outer ends of the beams and the ends of the sills, as and for the purpose substantially as specified.

In testimony that I claim the invention above set forth I do affix my signature in 35 presence of two witnesses.
