This invention relates to improvements in hose holders and, more specifically, to an adjustable holder for a cooling fluid hose used in connection with a horizontal boring machine tool or the like.

The primary object of the present invention is the provision of a device of the character described which will safely hold a hose in adjusted position and which will prevent any dislodging of the hose due to vibrations or due to a changing pressure of the fluid which passes through the hose;

Another object of the present invention is the provision of a device of the character described which will firmly grasp and hold the hose from four sides and whose lateral pressure upon the hose will increase whenever its pressure from above and below increases, so that the hose cannot be squeezed more or less flat from two opposite sides; I

Still another object of the present invention is the provision of a device of the character described which is simple in construction, easy to manipulate, and inexpensive to manufacture, but which is well adapted to withstand the rough usage to which devices of this kind are ordinarily subjected.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawing whether within or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.

In the drawing:

Figure l is a side elevation of a preferred embodiment of my invention as it appears when used in connection with a single end horizontal boring machine;

Figure 2 is a vertical cross-sectional view of the device drawn at an enlarged scale;

Figure 3 is a plan view of a detail; and

Figure 4 is a side elevation of the detail of Fig. 3.

Similar numerals refer to similar parts throughout the several views.

In the drawing, the numeral I denotes a matool table upon which rests a tool support 2 that carries a motor 3 and a revolving tool 4. A sliding table 55, holding the work W, is in a well known manner provided with T-shape'd members 6 which engage longitudinal T-slots l in the table l. The parts I to l inclusive forming no part of my present invention are illustrated in the drawing only for aiding in the description of my invention.

A supporting shaft 8, which has a threaded portion 9, extends upwardly from the sliding table 5, and can be vertically adjusted by screwing it more or less deeply into the table 5. A nut l0 allows a retaining of shaft 8 in an adjusted position, and the table is provided with a longitudinal slot ll, so that the lower portion of shaft 8 can be extended below the lower surface of the sliding table 5. The upper portion of shaft 8 is connected to a curved clamp l2 whose extremities are provided with'horizontal lugs to which upwardly extending threaded bolts I! are secured. A second clamp l3, which is of substantially the same shape and size as is clamp I2, is arranged above the clamp l 2; and the bolts I! are extended through the lugs of clamp l3. The clamps l2 and I3 are of considerable width, so that a hose I4 can be held safely between them. In order to make it possible that hoses of different diameters can be held by one and the same clamps I2 and I3, I prefer to make the curved portions of said clamps of a larger radius than is the outer radius of a medium sized hose ordinarily used for the conducting of cooling fluid to the rear of the work W.

Since such oversized clamps grasp the hose It only partially, I prefer to provide also for a lateral grip of the hose [4. I prefer to carry out this feature of my invention in the manner shown in Fig. 2, where it will be seen that two wedge members l5 are placed between the clamps l2 and I3 in such a manner that the tapering sides of each wedge member l5 are adjacent the inner side of the corner portions of the clamps l2 and I3, so that the wedges will be forced toward each other when the clamps l2 and I3 are being pressed toward each other by tightening of the screws [1. The wide front portion of each wedge I5 is curved (Figs. 2 and 4), and from the narrow portion of each wedge extends a longitudinal lug which is provided with a slot l6. These wedge lugs are located between the lugs of the clamps l2 and I3, and the bolts l! are extended through the and of a vertically adjustable supporting shaft connecting one of said clamps to a base, a pair of wedges from whose narrow portions slotted lugs are extended which are located between the lugs of said clamps, and threaded bolts connecting the clamp lugs to each other and extending through said wedge lugs, all substantially as set forth.

2. In an adjustable hose holder which comprises a pair of curved clamps from whose extremities lugs are extended, the combination of a pair of wedges from whose narrow portions slotted lugs are extended which are located between the lugs of said clamps, with threaded bolts connecting the clamp lugs to each other and extending through said wedge lugs, and a vertically adjustable supporting shaft connecting one of said clamps to a horizontally shiftable base plate, said wedgesbeing arranged between said clamps in such a manner that their tapering sides are adjacent the inner sides of said clamps so that the wedges will be forced toward each other when the clamps are being pressed toward each other, all substantially as described.
