JOHN T. PEARSON, or SYRACUSE, New voannssreuonmo on or SYRACUSE, new YORK, A coaronarrou or new YonK 1 enoumnme nnvrcn, on counncrnn Application filed August 14,1930; seria1 No; 175,21o.
This invention relates to grounding devices, or electrical connecters, particularly for grounding an electric conduit system toa grounded conductor, as a water pipe, which groundlng device isextrcmely simple 111 construction, readily applied to the grounded conductor, and highly efficient in use.
' The'invention consists in the novel features and 1n the combinations and constructions hereinafter set forth and claimed.
In describing this invention, reference is had to the accompanying drawings in which 7 beyond the ends ofthegroovesor-passages [formed-thereby. 1 1 1 like characters designate correspon ding parts in all the views.
Figures 1 and 2 are vertical, sectional views of this grounding device, taken at a right angle to each other, the conduit and grounded.
conductor being shown in Figure 1, and parts being omitted in Figure 2.
Figures 3, 4 and 5 are detail views of the body, the movable jaw, and the wedge.
This grounding device or connecter comprises generally,a body, a fixed aw carried by the body for engaging a grounded conductor, a movable jaw for coacting with the fixed jaw interposed between the body and the conductor, a wedge member movable between the body and the movable jaw and housed or 10 cated entirely within passages in the body" and the movable jaw, and means for operating the wedge, The body is also provided with electrical or mechanical means for connection to an electric conduitto be grounded and the wire passing through the conduit.
1 designates the body, which is in the form of a block.
2 designates the fixed jaw, which is here shown as a strap anchored at its ends to the top and bottom of the body or block 1 formrangement, the grounding device,
ing a loop forreceiving the grounded conductor or pipe P. The ends of the loop are secured to the body by screws 3, l, the latter passing through any oneof a plurality of holes 5 for determining the initial size of the loop, or to adjust the loop to different pipe sizes.
' 6 is the movable jaw which is arranged between the arms of the loop and adjacent thebody 1..
7 is the wedge movable between the block the screw, the washer thrusting against'like the block them more or less, and cause the movable jaw to grip'the pipeP, this wedgeji extending ousE -HInns co firm, I
or body landthe movable jaw 6to separate 7' transversely of-theblockyor "lengthwise of the jaw, and itfislocated in aligned on mat-- ,ing grooves Sandi? f ormedin theopposing Ysidesuof thebody 1' and the movable jaw 6,,
thebottoms of the grooves converging to- --ward-:each other and'conforming to the inclined edges of the wedge7; The wedge 7 is thus "housed entirely in the passage-"formed bythe grooves; that is, itrdoes not project ,The operating means for the wedge is a screw-lOextending lengthwise oi the grooves 8, 9, and threading'into the smallend ofthe wedge,"the'*s'crew having bearing means, as a washer 11 which underlies the1head12' of end faces of the body 1 and themovable jaw.
The-strapQ is first looped around the conductor P and adjusted tothe approximate size of the conductor by locating the screw 4 in one of the holes 5, and then the screw 10 operated to tighten the wedge and forcethe" movable jaw 6 outwardly; 1
13 is a body member having means as a collar for receiving the-conduit C to be grounded, the body 13 being adjustablysecured to the body 1 by means of a screw 14 1 extending through the body 13 and threading into a lug 16 projecting rearwardly from 1. The'body 1311s thus adjustable into different angular or radial positions relatively to the body 1. Also, the screw 14 is utilized to bind the wire W passing through the conduit 0 to the body 13. I
Owing to the wedge and its-relative arand particularly the assembly of the body 1, and the movable aw 6, and wedge 7 is particularly economical and symmetrical, as concealed entirely within, block and the movable j aw.
WhatIclaimisz 1 1. In a grounding device, a body," a fixed, jaw carried bythe body, a movable jaw for 1 or between the member'interposed between the wedge is it and the body, the body and the movablejaw being opposed to each other and formed with a passage in their opposing faces, and the wedge being located in said passage, and
I means for forcing the wedge into the passage.
2. In a grounding device,- a body, a fixed jaw for coactingwith a conductor, the-fixed jaw being carried by the body, and the mov- I able jaw interposed between the body and the 10 conductor, a Wedge member between' the body and themoVa-ble jaw, and means for ope'ra'ting the wedge member, the body and the movable jaw being provided with aligned grooves in their opposing faces,-and the wedge member being located in the grooves.
.3. A grounding device comprising ia :body in the form of a :block, a fixed jaw-compris in g alstrapanchored at its ends :to the body, a movable jaw in the iorm' of =a blockodfsubstantially the same width as the :body and 7 located between @the ends of the looped strap, the block fliIldFthQ movable j aw having aligned grooves in their 'op'posing iaces, a wedge mernber in said groove, and means for momingthe wedge'ineniber including a screw threading in the wedge member and' ha'vinga bearingpart thrusting against like ends of the block and the movable jaw,
In testimony whereof, I 'have hereunto 530 sig'nedmy name, at:Sy1-acuse,' in&the county of Onondaga, (145mm of ew' -Yo'rk, this '12th1day0f August, r1930. V V
