UNITED STAT S rATn 'r oni ion HJALMAJR. nnn'rz AND eusmvn o. MARX, or ELIZABETH, NEW JEnsnY, ASSIGNORS T0 DIEI-IL MANUFACTURING 00., OF ELIZABETH, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern Be it known that we, HJALMAR Hna'rz, subject of the King of Denmark, and GUSTAVE O. Manx, citizen of the United States, both residing at Elizabeth, in the county of Union and State of New Jersey, have invented new and useful Improvements in Universal Supports, of which the following is a specification.

This invention relates to supports for electric fan motors and the like.

' Supports for fan motors have been devised having two sections connected by a joint which will permit the sections tobe disposed in substantial alinement or at an angle to'each other. When the sections are disposed in substantial alinement the fan may be used as a table fan and when the sec- 4 tions are disposed. substantially at right angles to each other the fan may be used as a wall fan. Such a support for a fan motor is commonly known as a universal support.

One object of this invention is 'to provide an improved universal support for fan motors and the like. I

Another object is to provide a universal support having a substantially unbroken contour.

Other objects will appear as the specification proceeds.

One form of support constructed in accordance with the invention is illustrated in the accompanying drawings, in which" Figure 1 is an elevation of the support with an electric fan motor mounted thereon;

Fig.2 is aperspective view of the parts of the joint;

Fig. 3 is a vertical section of the oint;

Figs. 4 and 5are elevations of the joint, viewing the same from opposite sides; and

Figs. 6 and 7 are elevations of the joint,

viewing the same from opposite sides, the

same general shape as fan supports heretofore used and therefore the two sections 1 and 2 are so shaped that the two in combination give the desired shape and configuration .to the entire support. The upper section 2 supports the fan motor 4: which is herein represented as being of the oscillating type. The fan motor will not be described in detail as it forms no The base section 1 is adapted to rest upon a horizontalsurface such as a table, or it may be supported on a vertical surface such as a wall. In order that it may be held in place when supported on a wall it is provided with screw holes 5 orsimilar' means for securing the base to the wall.

Each section of the support is made of one piece and the adjacent extremities of the sections are so shaped as to constitute parts of a joint having a curved contour.

The construction of the oint itself will be clear from Figs. 2 and 3'. The adjacent extremities of the two sections of the support are laterally recessed so that an upstanding wing or projection 6 is formed on the lower section of the support, and a similar projection 7 is formed on the upper section of the support. Whenthe joint is assembled the flat vertical faces of the extensions 6 and 7 lie in substantially the same plane and are clamped against each other by means of a clamp screw 8 inserted through openings 9 and 10 that are in alinement when the parts of the joint are assembled. 'The clamp screw 8 fits loosely into the opening 9 of the upper section but has threaded engagement with "the opening 10 in the lowerfsection. A head 11 formed on the clamp screw 8 permits the clamp screw to be easily operated.

The lateral face of the extension 6 is provided with a washer 12, the peripheral edge of which is corrugated as shown at 13. Likewise, the lateral face of the extension 7 is provided with a washer 14, the peripheral part of'the present inedge of which is corrugated as shown at 15. When the parts of the joint are clamped against each other the corrugations of one of the washers fit into the corrugations of the other washer and serve to firmly hold the sections of the support in their adjusted position.

Two

pins

16 and 17 project from the lateral face of the extension 6 and a single pin 18 projects from the lateral face of the extension 7. When the sections of the support are in alinement the pin 18 projects between the two

pins

16 and 17, as'shown in Figs. 4 and 5, and permits only limited movement of the support sections. When the sections of the support are at right angles to each other the pin 18 engages the pin 16 at the outer side thereof, as shown in Figs. 6 and 7, to lock the sections in their righteangle position.

The upper extremity of the extension 6 is rounded and the adjacent surface 19 of the other section is also partly rounded so that these surfaces are partly complementary. Likewise, the lower extremity 20 of the upper section is rounded and is partly complementary to the adjacent surface 21 of the lower section. The joint is therefore somewhat of the type of a ball joint.

The surfaces 19 and 21 are not complementary throughout their whole area to the rounded extremities of the support sections because if such were the case the support sections could not be disposed at right angles to each other. In order to permit the sections to be disposed at right angles to each other the surface 19 of the upper section is so shaped as to provide a clearance 22 (Fig. 4c), and the surface 21 of the lower section is so shaped as to provide a clearance 23. The sections of the support may then be disposed at right angles to each other as shown in Figs. 6 and 7, as the

clearances

22 and 23 permit full movement of the support sections to the right angle position.

When it is desired to change the angular position of the support section the clamp screw 8 is loosened and the two sections are moved apart sufiiciently to permit the pin 18 to pass by the pin 16 or the pin 17. If the support sections are to be placed in alinement the pin 18 is made to project between the

pins

16 and 17 as shown in Figs. 4: and 5, but if the sections are to be disposed at right angles to each other the pin 18 is made to engage the pin 16 at its outer side as shown in Figs. 6 and 7 The clamp screw is then tightened and the sections of the support are firmly held in their adjusted position.

The joint is so formed that the external lines of the joint are in symmetry with the external lines of the support. This is clearly shown in Fig. 1 from which it will be noted that the general outlines of the support are substantially the same as if no joint were used in the support. The presence of the joint therefore in no way detracts from the pleasing appearance of the support. As the support sections are made in' a single piece, and as the parts of the joint are formed directly upon the support sections, the support is very simple in construction and is formed of a minimum number' of parts. Furthermore, this feature contributes a share in producing a support whose simple and pleasing outlines are not interrupted. No matter from what direction the support may be viewed the straight simple outlines of the support are preserved as is evidenced by Figs. 1, 4 and 5 which show the joint viewed from three different directions. 7

The support maybe found useful for numerous devices and the electric fan motor is herein illustrated merely to show one of the applications of the support. It is obvious that so far as the construction of the support is concerned it is immaterial what particular device is supported thereby.

Furthermore, the specific construction of the interior of the joint is immaterial to the present invention. For instance, the corrugated washers 12, and 14: and even the

pins

16, 17 and 18 may be omitted if desired and various other changes may be made in the interior details of the joint.

l/Vhat we claim is:

A support for electric fans and the like comprising a pair of pivoted sections, the adjacent extremitiesof which are reduced in thickness so that they will be complementary, the extreme end of each section being rounded, and the portion of the other section adjacent to such rounded end being concave to receive such rounded end, the surface of each section in the vicinity of the joint being smooth and unbroken, and said concave portions having a clearance to permit said sections to be placed substantially at right angles to each other.

In witness whereof we have hereunto subscribed our names.
