To aZZ whom it mag concern:

Be it known that I, ELIJAH FALK, a citizen of the United States, residing at Eureka, in the county of Humboldt and State of California, have invented a new and useful Foundation for Band-Saw Frames, of which the following is a specification.

This invention relates to foundations for band-saw frames.

The object of the invention is to provide a foundation in which the elements of decay and shrinkage shall be positively eliminated and in which vibrations shall be positively obviated.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a foundation for band-saw frames, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in side elevation of the foundation. Fig. 2 is a view in end elevation thereof. Fig. 3 is a view in horizontal section taken on the line 3 3, Fig. 1, and looking in the direction of the arrow thereon and showing more particularly the base of the foundation and the manner in which the supporting members or beams are combined therewith. Fig. 4 is a vertical transverse sectional view taken on the line 4 4, Fig. 1, and looking in the direction of the arrow thereon. Fig. '5 is a sectional detail view exhibiting more particularly the manner in which the uprights or columns are combined with the base. Fig. 6 is a perspective detail view of one of the top plates used in connecting the columns upon which the frame of the band-saw will rest. Fig. 7 is a pers ective detail view of one of the steppingp ates or illow-blocks with which the supporting-co umns are combined. Fig. 8 is an inverted perspective view of the steppingplate shown in Fig. 7.

Referring to the drawings, 1 designates the base of the foundation, which is constructed, preferably, of concrete and has embedded therein eight angularly-disposed anchor- bolts 2, 3, 4, 5, 6, 7, 8, and 9, the anchor-bolts 2 to 5 being disposed at the sides of the base and the anchor-bolts 6 to 9 at its ends. The anchor-bolts may be of any preferred construction, and each is a counterpart of the other and consists of a shank having at each end a ring or eye 10 and 11, the eye 10 serving as a means of holding the bolt from possibility of being withdrawn from the base and the eye 11 serving as a means by which strainingrods, presently'to be described, are combined with the respective anchor-bolts. While an eye 10 is herein shown as a means of holding each anchor-bolt against detachment, it is to be understood that the invention is not to be limited thereto, as a nut'or. any other equivalent means may be employed for the purpose and still be within the scope of the invention.

Near each corner of the base is a cruciform socket 12, each of which is adapted to be engaged by a stepping-plate 13, (shown in detail in Figs. 7 and 8,) the said plate being preferably of cast-iron and providedon its under side with a cruciform rib 14 to engage with the socket 12 and on its upper side with an I-shaped socket 14 to be engaged by one of the supporting-columns presently to be described. The rib 13 is secured within the socket 12 in any preferred manner that will insure rigidity and freedom from liability of loosening under vibrations to which the structure will be subjected in use. Each of the stepping-plates is engaged by a column 15, of which there are four, and, as shown in Fig. 3, are I shaped in cross-section, thus to fit snugly within the socket 14 of the stepping-plate. Viewed from the ends of the base and as shown in Fig. 2 the columns are disposed in parallelism, but inclined toward each other, as shown at Fig. 1, and are rigidly secured together by cross-beams 16, Fig. 1, which extend longitudinally of the base. These crossbeams are preferably T-shaped in cross-section, as shown in Fig. 4, and are provided withend flanges 17, that are inclined in opposite directions relatively to each other and on angles corresponding to the incline of the beams and are secured thereto by bolts 18, which pass through the inner flanges of the columns, as clearly shown in Fig. 1. The up-.

per ends of the beams at the ends of the base are connected by top plates 19, (shown in detail in Fig. 6,) the same being preferably T- shaped in cross-section and having their webs 19 provided with terminal perforated flanges 20, extending at right angles to thelength of the plate, through which are passed bolts 21, that serve positively to combine the ends of the plate to the beams. By the employment of the cross-beams 16 and top plates 19 it will be seen that the beams 15 are connected both laterally and longitudinally and are braced against any tendency to vibration or rocking movement.

In order to secure the superstructure formed by the columns 15, cross-beams 16, and top plates 19 to the base, straining-rods 21 are employed, there being eight in all, two

on each side and two at each end, and as each is constructed and combined with the base in the same manner a description of one will serve for all. Each straining-rod is provided at its upper end with a loop or eye 22, which is adapted to engage with a pin 23, four of which are arranged in the webs of the crossbeams 16 and four in the webs of the top plates. Each straining-rod consists of two members connected by a turnbuckle 24, the lower member of each rod being provided with an eye 25, which is engaged by a link 26, Which also engages the eye 11 of the anchorbolt, the object of the links being to permit the straining-rod to find its center and alinement when the turnbuckles are operated to place the rods under the desired tension. It will be seen that when the rods are under tension the beams 15 will be forced down into the sockets of the stepping-plates and held positively therein against possibility of movement. In case there should be any vibration this may be readily counteracted by applying additional strain or stress to one or more of the rods, as may be found necessary.

Each top plate has combined with it three chipping pieces or strips 27, formed with dovetailed grooves 28, and these strips are designed to be planed off and tinned, and after the foundation is erected Babbitt metal is run over the strips and then trued, after which the foundation is ready to receive the frame of the band-saw.

It will be seen from the foregoing description that although the improvements herein described are simple in character they will be thoroughly efficient in securing the object designed and will be positive in supporting a band-saw against vibrations or settling, an objection common to most foundations now in use.

Having thus described the invention, what is claimed is 1. A foundation for band-saw frames comprising a base having its upper face provided with cruciform sockets, stepping-plates lawing their under faces provided with cruciform ribs to engage the sockets and their upper faces with I-shaped sockets, I-beam columns having their lower ends in engagement with the last-named sockets, means for connecting,v

the upper portions of the beams, and means for holding the beams within the sockets.

2. A foundation for band-saw frames embodying a base, stepping-plates carried there-. by and provided in their upper faces with I- shaped sockets, I-beam columns having their ends seated in the sockets cross-beams longitudinally connecting the I-beams near their upper ends, top plates transversely connecting the I-beams at their upper ends, straining-rods having their upper ends secured to the crossbeams and top plates, and means for adjustably connecting the lower portions of the straining-rods with the base.

3. A foundation for band-saw frames embodying a base, stepping-plates carried thereby and provided in their upper faces with- I- shaped sockets, I-beam columns havin their ends seated in the socket, cross-beams ongitudinally connecting the I-beams near their upper ends, top plates transversely connecting the I-beams at their upper ends, crossed straining-rods having their upper ends secured to the cross-beams and top plates, and means for adjustably connecting1 the lower portions of the straining-rods Wit the base.

4. A foundation for band-saw frames comprising a base, obliquely-disposed anchorbolts embedded therein, steppingplates secured in the upper face of the base and provided with sockets, columns having their lower ends seated in the sockets, crossed beams longitudinally connect-ing the I-beams top plates transversely connecting the 1-
