MACHINE MOUNTING.

Application filed April 2K, 1926, Serial No. 99,247, and in Germany May 14, 1925.y

rlhis invention relates to adjustable mountings for machines, such as are driven by belts, for example, and are allowed a limited extent of mobility to or from the driving pulley, so that the belt may be kept at a proper tension.

The general object of the invention is the provision of a construct-ion which affords a simple and secure adjustable mounting permitting the adjustment of the machine du-- ing operation.

`Another object is the provision of a construction which allows a very considerable scope of movement for the machine, without requiring prolongation of the adjusting and securingl elements.

Another object is the provision of a construction in which standard commercial rolled shapes may be utilized as the bed rails for supporting the machine withoutspecial forming for connection of the adjustable securing elements. Y

Yet another object isithe provision of an adjustable machine mounting` which will accommodate an extensive span of adjustment, and also impose no minimum limitations on the extent of the adjustment of the securing members on the rails.

Other and further objects will be pointed out hereinafter, indicated in the appended claims or obvious to one skilled in the art upon an understandingof the invention.i

In the drawing forming a part of this specification I show various forms which the invention may take, but it. is to be understood that the claims are not intended as limited to these forms alone. In the drawing Fig. 1 is a detail in the nature of a fragmentary side elevation of a portion of a machine frame and the supporting and adjusting means.

Fig. 2 is a transverse section through one of the supporting bed rails such as shown in Fig. 1, showing the anchor block in front elevation.

Fig. 3 is a fragmentary side elevation of another form of anchor block with its ad.i justing screw.

Fig. 4 is a transverse section of same on line 4 4.

Fig. 5 is a longitudinal section through a portion of another form of mounting.`

Fig. G is a transverse section of same on line 6 6.

Fig. is a longitudinal'section through a. part of a further form of mounting, and

Fig. 8 is a transverse section through same on line 8 8.

In the Vforms shown in Figs. 1 and 2, M designates a. portion of -a machine frame which is supported on bed rails 10, for sliding adjustment longitudinally thereof. The bed rails preferably are commercial rolled shapes, in this instance of T section with flanges Z; and o.- Adjustably mounted on the rails are the anchor blocks 11, in the form of bifurcated members properly` proportioned to the rail section to receive the web and `upper ilange and to stand above the latter to a proper height to receive the screw 12 and support it at the suitable elevation to engage the machine frame M. The arms of the anchor member have inward extensions g extending between the rail ianges and formed with the biting edges a, spaced apart longitudinally of the rail and adapted to engage the opposing flanges, under .pressure in the direction of the arrow shown in Fig. 1, to bind the anchor block firmly to the rail. This is accomplished when the yscrew 12 is set up against the machine casing. When freed Vfrom this pressure, however, the anchor block may be freed from the rail by tilting the block opposite the direction of the arrow, whereupon it may be shifted longitudinally on the rail. In this fashion an extensive range of adjustment is afforded the machine without requiring a very long adjusting screw, and the-anchor block may always be kept close to the machine frame, thus making for security in the mounting. The anchor blocks may be madeof steel or wrought iron, and the biting edges hardened, and the cooperating surfaces of the rail vflanges may be roughened or ribbed.

In Figs. 3 and 4 is shown a modified form in'which the anchor blocks 111v engage only the lower flanges of the rails, binding thereon by `means of the members g1.y In this arrangement the bed rails are supported on blocks 111, to give space beneath them for the lower binding extensions g1. In Figs. 5 and 6 is shown a modification of the first form wherein the rails are formed of two channels 101 set facing and connected by spacers 15.

The anchor blocks 11a lit between them so that the binding extensions 1* project in opposite directions.V They have the biting edges'h as in the first instance. The form shown in Figs. 'i' and 8 is a similar modiication of that shown in Figs. 8 and 4, the anchor blocks 1lb having binding extensions n engaging only the lower Vianges ot' the opposite channel members.

Vilhat claim is z l. A machine mounting comprising, in combination, al bed rail, a machine frame shiftably mounted thereon, an anchor block shiftabiy mounted on ythe rail, said anchor 'leek having' binding portions iter biting engagement with the rail, and an adjustable member cooperating with the machine frame to hold the binding portions in iXed engagement with the rail. y Y

Q. it. machine mounting comprising a bed i rail, a machine iframe shiftably mounted tiereon, an anchor block shiftable on the rail,V
