"i i My invention relates to improvements kin jclainps especially designed for the securement of fronts or covers, to cabinets, or boxes con tainingA electrical devicesv Ysuch as` panelboards. n Y' Y Y My object is to provide a deviceof simple,
strong, durable and inexpensivel construction` yComprising'elements providing both angular and distance adjustment, relatively, whereby frontsv torv panel board boxes' maybe selectively positioned and secured tofxedjboxes or cabinets. Y rMy improvements consist in the novel construction, arrangement and combination fof parts as hereinafterfully, clearly and concisely described,ldenitely pointed outY in my claims .and illustrated bythe accompanying drawing in which Figs. l, 2 and 3 are, respectively, an'elevation, a plan view and a transverse section .of the clamping element; Figs. 4 and 5 are, respectively, a plan-view and a transverse section of the swivelinut; Fig. 6 isa view of the clamp as employedin connection with'a front resting directly upon the box; and Fig; 7 is a' View, similar to Fig. 6, showing the clampV YasV employed in connectionwith a `front spaced away from the box.
Referringto the drawing, A designates a s box or cabinet, for electrical panelfboards, or

In the `surface type the cover, or front B, is directly attachable to the box A, and inthe fiush type the front is spaced from vthe box, as by plaster, or other wall surfacing, surrounding a wall cavity. I A
The clamp of my invention functions'with equal facility and eiiiciency in the securing of Y fronts, or covers, to boxes'of either surface or Hush installation, and, to this end, com- Y Yelement D.
prises essentially Van element C having arms 10 and 11, an element D having swivel connection with the element C, andan .element having variable distance' relation withjthe By preference the element C is formed vout of a single piece of sheet metal, out and internallythreaded.j Y n' `IThe element E is vby' preference an ordinaryshaped to form a substantiallyillfshapedbody havingV a' p air ofzcheeks, or sides, 12, a bridge, or "connecting piece, 13, andA thefarms 10 and 11,- forined asintegral continuationsfo-ff'the rvino 16-'having a -iange,lrib','orfburr, 17,' and' screw, having -a head 1 8, anda threaded' shank 19,"the head forminglan abutment for seating about a hole; 'forn'ied in'the front Band thef Yed f threaded shank forming a connection provid# ingdistance"l adjustmentbetween the head 18 'andthe element D.

VHaving thus described my invention, what ina' f I claim as new therein and desire to secureby Letters Patent is v:- Y Y 1. In a` device of the class described, asubstantially U shaped clamping element, the bridge portion thereof having an elongated openingvtherethrough, a unitary element substantially semi-'cylindrical in form and having swivel connection with the clamping ele ment and an element having variable distance relationship -wilth the swivelled element, and
