UNIVERSAL HANG ER.

SPECIFICATION forming part Of Letters Patent N0. 548,808, dated OCtOber 29, 1895.

Application iiled July 23, 1894. Serial No. 518,331. (No model.) l

To all whom t may concern:

Be it known that I, ERNST J. MULLER, of Butte, in the county of Silver Bow and State of Montana,- have invented certain new and useful Improvements in Universal Hangers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of this specification.

The main objects of my invention are to facilitate the alignment of a number of boxes with each other without disturbing the brackets, hangers, or stands which support them, to prevent the boxes from binding on the shaft which they support by permitting them to turn in any direction transversely to their axes,and thereby adapt themselves automatically to any ordinary springing or deflection of the shaft from a straight line, and to provide for a slight adjustment of the shaft in 4any direction transversely to its axis.

It consists, essentially, of certain novel features in the construction and arrangement of the box supporting and adjusting connections, as hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same partsin the several tigures.

Figures 1 to 6, inclusive, show one form of my universally-adj ustable bearing adapted to hangers, Fig. l being a side elevation and partial vertical section transverse to the axis of the box; Fig. 2, a front elevation of the same; Fig. 3, a horizontalsection of the yoke on the line 3 3, Fig. 1; Fig. 4, a vertical section parallel with the axis of the box on the line 4 4, Fig. 1; Fig. 5, a horizontal section on the line 5 5, Fig. l; and Fig. 6, a vertical section on line 6 6, Fig. 1. Figs. 7 to 10, inclusive, show a modification of the bearing, also adapted to hangers, Fig. 7 being a vertical section crosswise of the box and a partial side elevation; Fig. 8, a front elevation; Fig. 9, a horizontal section on the line'9 9, Fig. 7; and Fig. 10, a vertical section on the line l0 10, Fig. 7. Figs. 11 to 14, inclusive, show still another modification of the invention,

Fig. 1l beinga partial side elevation and vertical section crosswise of the box; Fig. 12, a front elevation; Fig. 13, a plan view of the lower half of the box and the yoke supporting it; and Fig. 14, a horizontal section on the line 14 14, Fig. 11.

v Referring to Figs. 1 to 6, inclusive, A designates a bracket or hanger adapted to be bolted in the usual manner to a ceiling or overhead support and formed in line with each other with split hubs ot a', which are provided with clamping-bolts a2 a2. In one hub a is threaded a hollow screw or sleeveB, having a squared end b, and in the other hub a is fitted a plain sleeve C.V D is a yoke formed on opposite sides with hollow stems d d', fitted, respectively, into the hollow screw B and sleeve C. The stem ol is provided at its outer end with a washer cl2, secured thereto by a bolt cl3, whereby said stem is secured in the hollow screw B and prevented from moving endwise therein, said screw abutting at its inner end against a shoulder on said stem and at its outer end against said washer. Sufficient play is allowed to permit the stem to turn freely in said screw. Said yoke is formed perpendicular to the stemsdd,with a sleeve d4, in the lower end of which is threaded a hollow screw E, squared at its lower end c.

F designates the box, the lower half of which is formed or provided with a vertical stem f,

reduced at its lower end and fitted in the hol- Y low screw E, in which it is secured bya washer e and bolt c2. The unreduced portion of said stem f is fitted to bear and turn in the upper end of the sleeve d4. For convenience in manufacturing and assembling the parts of the hanger the stems d d are flattened on the sides, as shown in Figs. 3, 4, and 6, so as to admit of their bei ng passed sidewise upwardlybetween the ears of hubs a a into the bores thereof. sleeve C are then passed over the ends of said' stems and inserted in said hubs and when properly adjusted are secured in place -by the clamping-bolts a2. The sleeve d4 of yoke D is split at its lower end and formed on opposite sides-with ears, which are connected byV clamping-bolts d5 d5, as shown in Figs. 2 and 5, whereby the screw E may be secured in place when adjusted, as desired.

The stems d and d being free to turn in The screw B andv IOO their bearings in the bracket or hanger A, and the stem j", at right angles thereto, being free to turn in the sleeve d4 of yoke D, it is obvious that the box F has universal-joint connections with its support and is free to turn in all directions about its center and to adapt itself to any springing or deiiection of the shaft which it supports from a straight line.

By loosening the nut or screw a2 in hub ct and turning the hollow screw B thus released, by means of its squared end h the box F may be readily adjusted horizontally transversely to its axis, and in like manner by loosening` the nuts on bolts d5 in sleeve d4 and turning the hollow screw E, thus released, said box may be adjusted vertically. The alignment of a number of boxes with each other is thus readily effected without disturbing the brackets, hangers, or other supports which carry them.

The hollow screw or sleeve B, threaded in the bore of hub d, and the stem d of yoke D constitute an adjustable pivot connection between the hanger A and said yoke, and the hollow screw or sleeve E, threaded in the bore of sleeve d4, and the stem f of box F constitute a similar adjustable pivot connection between said yoke and box.

Referring to Figs. 7 to lO, inclusive, showing a modification of the device, A designates a bracket or hanger adapted to be secured to a ceiling or other overhead support in the usual manner by bolts and formed with hubs a a3 in line with each other. The hub a, is split and formed on opposite sides with ears, which are connected by a clamping-bolt a2, as shown in Figs. 8 and l0.

B is a hollow screw threaded in the hub a and formed with a squared end h, by means of which it may be turned therein.

D is a yoke formed on opposite sides with internally-threaded hubs d6 d6, in which are secured pivot-pins G G in line with each other. The pivot-pin G is formed with a head g, between which and the adjacent hub d6 the hollow screw B is held thereon, sufficient play being allowed to permit said pin to turn freely in said screw. The pin G is fitted in the hub a3, and squared at its outer end to receive a wrench for turning it into and out of the hub d6. Said yoke is also formed in a line perpendicular to the pins G G with hubs Z7 and d8. The box F is formed or provided on the lower half with a hollow internally-screw-threaded stem f', which is tted to turn in the hub C17.

H is an ad justin g-screw threaded in the hollow stem f and formed with a plain extension or shank h, which is iitted to turn in the hub d8, and held therein by a head or shoulder h and a nut h2. It is provided with a checknut h3, which is forced against the lower end of the stem f to secure the parts in place when they are properly adjusted.

To assemble the parts of this form of my improved hanger, the yoke D', with the box F, is placed between the hubs a a8 of the hanger, with the hubs d d6 in line therewith. The

pivot-screws G G are then passed from the outside through the hollow screw B and the hub d3, respectively, and screwed into said hubs d6. The horizontal adjustment of the box is effected in the same manner as explained in connection with the form shown in Figs. 1 to 6. The vertical adjustment of the box is accomplished by loosening the checknut h3 and turning the screw H by means of its nut h2, which is pinned thereon for this purpose.

Referring to Figs. ll to il, inclusive, show'- ing another modification of my improved bearing, the hanger or bracket A2 is formed or provided with internally-threaded hubs d4 in line with each other, and in these hubs are threaded pivot-pins l I, which are provided with check-nutsz' t' for securing them in place when they are adjusted as desired. The yoke D2 is formed on opposite sides with hubs d, having sockets to receive and afford bearings for the ends of the pivot-pins I I. It is also formed with hubs d7and d8 in a line perpendicular to said pivot-pins,like or similar to those shown in Fig. '7. The box F is formed or provided on the under half with a stem f2, the upper part of which is fitted to turn in the hub d"l and the lower part of which is reduced and externally screw-threaded.

J is a sleeve fitted to turn in the hub d8 and made a little longer than said hub. The reduced portion of the stem f2 is made to pass loosely through said sleeve and is secured therein by nuts f3 and f4, the nut f3 being placed on said stem in an opening in said yoke and formed with holes in its edges to receive a spanner wrench or pin for turning it.

The box is adj usted horizontally by loosening the check-nuts t' i and turning the pivotpins I I in or out, as required, of the threaded hubs a4 a4. The vertical adjustment of the box is effected by turning the nuts f3 andf4 up or down on the threaded stem f2, as required. When adjusted as desired, it is secured in place by turning the check-nuts t' t' against the hubs a4 and the nuts f3 and f4 against the ends of the sleeve J.
