WILLIAM W. MILLER, OF NEW YORK, Y., ASBIGNOB TO THE CUTLER-HAMMER MIG. .CO., OI MILWAUKEE, WISCONSIN, A CORPORATION 01' WISCONSIN.
' ms'rmcn Application nled'hbruary 18, 1988. Serial Ito. 586,058.
To all whom it may concern:
Be it known that I, WILLIAM W. Mnmm, a citizen of the United States, residing at New York, in the county of Bronx and State of New York, have invented new and useful Improvements in Resistances, of which the following is a full, clear, concise, and exact description, reference bein had to the accompanying "drawing, forming a part of this specification.
This invention relates to resistances, and more particularly to the mounting and terminal arrangement of resistance elements having insulatin bases withwhich'the resistor is associated y winding or otherwise.
In the construction and assembly of such resistance elements great difliculty has heretofore been experienced in providing for support and mounting thereof with adequate ruggedness and resilience to insure permanence of the installation, and the present invention has among its objects that of overcoming such .difiiculty.
Another object .is that of providing combined supporting and terminal means for such resistance elements enablin stacking thereof in a manner to simulate t at of the ordinary grid resistance.
Another object is that of providing for such resistance elemen detachable supporting terminals providing for rugged and reliable mountin of the elements in different desired relations.
Another object is that of providing a resistance unit having supporting terminals which may be adjusted with reference to the resistance element or elements to provide for arrangement of the latter in different relation with reference to other units and to the source of energization.
Another object is that of providing an exceedingly simple, rugged and durable sup orting termlnal device which may be rea ily applied and rearranged with re-- spect to a resistance element to provide for use of the latter in different relations.
Other objects and advantages will hereinafter appear.
In the accompanying drawing wherein is illustrated an embodiment of the invention;
Fig. 1 is a front elevational view showing a given relation of a pair of resistance elements embod ing the resent invention. Fig. 2 is. side elevational view of the same;
Fig. 3 is a view similar to Fig. 1 but illustrating the resistance elements in different relation; while Fig. 4 is a side elevational view of the resistance elements arrangedasin Fig. 3.
Referring to Fig. 1, the same illustrates a pair of resistance elements of conventional form, each being provided at its ends with sup orting terminal devices more fully descri ed hereinafter, said devices being arranged in a particular manner to provide for support 0 said elements in a particular manner and to facilitate connection of the elements electrically in parallel relation to one another.
The resistance elements illustrated may be of practically any standard t e, each pref- A era 1ycomprising an ins ating base 5 having a resistor 6 wound thereon, a coating 7 of enamel or other insulating material being preferabl a plied and permanently secured about t e Ease and the resistor as by adhesion. Theresistor is provided at its ends with projecting terminal portions such as the portion 8 illustrated.
The herein contemplated sup orting terminal devices for the aforedescn ied element preferably comprise a pair of metallic or other conductive strips 9 secured respectively to the end' portions of the base 5 of the element substantially as illustrated.
In practice the members 9 may comprise castings, punchings, stampings or the like each being shaped to correspond with the analogous terminal portion of a grid resistor and comprising an elongated .lug or shank 10 of such thickness as to afford ample mechanical strength with a given amount of flexibility or resiliency, and preferably of a length somewhat less than the width of the base to which it is attached. Each member 9 is further provided with an enlarged portion llextending a material distance beyond the adjacent side of the resistance element and also ofiset later ally to extend a considerabledistance outwardly beyond the adjacent end of its associated base. The portion 11 is further more enlarged in the direction of greatest length of its associated base, the enlarged portion being provided with a relatively large 0 ening 12 to receive the usual mounting ro or bar. Further the portions of the member 9, adjacent said openin 12 may be made of materially increased t 'ckness relregister with correspon corresponding portions of the base 5, thereb provi for securement of the latter to t e former y means such as the screw 14 g openings in the and bolt lfiillustrated. In practice the terminal ortions 8 of resistor 6 are preferably bent 9. out and clamped by the b ts 15 sub- ,stantially as illustrated, whereby the members 9 are ada ted to serve as terminals for the resistor. stood that other securing means may be substituted for those descnbed, if deslred.
As illustrated particularly in Fig. 1, the members 9 are secured to the opposite ends but preferably upon the same side of'the individual resistance elements, and each is arranged to project from the same ed of the individual element, thereby providing for two point suspension of the assembled unit by means of rods or bars in the usual manner while also facilitating connection of the individual elements in parallel relation to one another electrically.
Again referring particular to F 2,-it is apparent that the thickness or stac g of the assembled unit is minimized and is not materially in excess of that of a grid resistor of corresponding v general dimensions.
' Referrmg now to Figs. 3 and 4 of the drawin the resistance units and also the supporting terminals therefor are in all res cts similar to those aforedescribed.
owever, the relation of the supporting terminals tor-the individual units has been changed toprovide for three point rather than two pomt suspension of the resistance units when mounted in groups of two. upon supportin rods. Also connection of the re- .sistance'e ements in series relation is facilitated.
The specific difference in arrangement consists in assembling the supports upon the base to project from opposite edges thereof rather t an from the same edge as in the previous construction and here a ain by.
reference to Fig. 4 it is apparent t at the thickness of the assembled group of elements does not materially exceed twice the thickness of the conductive material surrounding the opening 12.
It is of course ap arent that if desired the portions 11 of t e members 9 ma be interruptedto provide for assembly of the unit laterally upon its supporting rod. Also in certain cases it may be desirable to effect integral construction of those elements 9 which when assembled would register with one another. Further it is of course obvious individual resistance elements in difier t is if course, to be under-.
that the units in Fi may, if I desired, be connected electrica y in'series relation to one another through interposition of suitable spacers between the adjacent members 9 of said units, the spacer located between the members 9 at one end of each pair of units being conductive and the spacer between the said members located at the opposite end of such pair of units bein insulating in character. a a
By the foregoing construction and arrangement it is apparent that exceedingly simple, durable an eifective terminal su porting means for a resistance element is. provided, whereas the aforedescribed functional flexibility provides for adaptation of the resistance elemlents mounting in groups or units an in erent arrange merits, including those particularly escrlbed.
