To all whom una y concern: I Be it known that I, Fmnnnrcn Wrnnnmr' NmoLAbs HAYN, a subject of the Emperor of German'ygpresiding at Bahia, Brazihi 5 have invented mewgand useful Improvements in Contact Devices,, ((lase No. 81,)of whichtlie l following is a specification, and for whichi Letters Pateznt No. 118,724, tediDecember 322,1895, andli'n;
My invention relates to a contact dexiice} for electrical conductors, especiallyadapted for use with overhead trolle y-wvines.
The object of myfinvention is to providena contact device that shall mi'niniinetthe wear upon the current-conductor rand ,medsucethe sparking and noise Without; imparting the electrical contact. a I
The device of my present applicationconno sists of an aluminiumcontact-bar,whiclrmay be ,provided with longitudinal groo'vcsadapted :to be filled with lubricating material or soft metal. I I
"I will describe my invention more particulanly by reference to the accompanying drawings, :in which- 1 Figure 1 is a side view-of my devlce. 1
2 is a section al view thereof. Dig. 3'is a view of my device wherein 0011061121110 contact-bars the same.
Like letters refer to likepar'ts in the several figures.
The contact-bar of my invention is constructed of aluminium, which I find well adapted to this purpose by reason of its light weight and tensile strength ilizurthermore, aluminium is acomparativelysdft metal and will wear the current-conductor away very slowly. In its preferred form lprovide in my aluminium contact-bar a a groove 1), extending throughout its length, so that a section thereof is U-shaped. This groove I fill with one of the softer metals or some lubricating material, by which means I further reduce the wear and friction between the contact device and current-conductor. In some cases I have secured more advantageous results by constructing my contactbar of two or more of these U-shaped aluave been grantediinaB'elgin-m,

are employed. Fig. 41s a sectional View of I sm'iniuiri llllfillS C-b'i, fitting one within another :and securing together, so that con tinnzous longitudinal spaces b b are maintained ibetweennflhe sides nit-said bars. 'flhesespaces :and the ggmooveib :ame filled with:soft:n1etal or lubricatt ing material or part with metal and part with .a lubricant. This form of currentcollectorilhavetfioxund to be ad miirablyadapted to the user-for which it is designed.
By making my device of aluminium the weight thereof is reduced to a minimum, while the necessary rigidity of construction is maintained, The inertia of the device is slight, by reason of which the force ten-ding to separate the contact from the trolley-wire, when the contact device is in operation, is materially reduced and the spring-pressure serving to force the contact-bar againstthe current-conductor may aecordin gly be greatly decreased, thus further reducing the friction and wear between the contact parts.
Additional good I results attained by the use of the device above described are an entire absence of noise and the elimination of sparking to a large degree. After an experi- 5 mental use, extending over a period of six months, the advantages above claimed for this device have been practically demonstrated. Throughout the tests the contact wasi'found to be uniformly good, and the wear of (the contact parts atthe end of six months was scarcely appreciable. I
flaming thus described my invention, what I claiinas new, and desire to secure by Letters Patent, Eis- 1. In .a contact device, the combination withacontact-bar constructed of aluminium a crossssection whereof is U-shaped and the edges thereof are adapted to engage the current-conductor and complete the electrical 0 circuit therewith, of material adapted to re duce the friction and wear of the contact parts disposed in said device adjacent to the contact edges of the bar, substantially as and for thepurpose specified.
2. In an electrical contact device the combination with the U-shaped aluminium c0ntact-bar the edges of which engage the current-conductor and complete the electrical circuit therewith, of spaces or grooves prozoo vided in said bar adjacent to the contact edges and a filling therefor of material designed to reduce the friction and wear of the contact parts, substantially as descfibed.
3. In a contact device, the combination with the U-shaped aluminium contact-bars a a secured together, of longitudinally-extending grooves b b b provided therein and a filling for said grooves of material designed to reduce the friction and Wear of the 0011- I0 tact device and current-conductor, substantially as described.
In testimony whereof I afiix my signature in the presence of two witnesses.
