all wiwm awesome; 1 no il n l, Joan Bnown, o'i'iiizon of no Unite'vs States, residing Mls1'isficl.d,-tne county of Rieliloml anal 5 of Ohio, have invented certain l rovemsnts .l loil-lB-m'icls oi wing is s'specification. 7 My invenlion Icolales to that class of cle- Vices known as rail bonds the purpose of which is to join the adjacent. ends of rails logc'bsr electrically.

invention has as its object a device zvnich is cosy of manufacture and thereforo 7 I sml which is simple and. cosy fclie mil.

object is to pmdnce a device an n4; often insballolsion in cone aciiric current from mil to roll,

a: soother object is to produce a bond: vliich is capable of being installed by such, means s to mobs iis attachment to the mil pow mon-snily ellicient. and avoiding deterioyotion as in the case" of pin expancled, riveted or bolted type of bonds.

These and other new nnrl useful objects will later ore secured and osi'oinerl by the novel construction, combination and orz'ongement'of points of which my invention comoosofi oncl which will appear later as more fnll -"ibcd and. claimed and shown in 2w ompaw ings in Wl"lCh3-- is s, elevation of my bond force applied exmic - 335. slim elevation in full of tho boiriii on lane toil and connecting adjacent mil coils o eti'icolly.

have found that a, boncl constructeel of o. copper cable body composed of o olurolity of *wistecl wires or of a. plurality oi ribbons havingatlnchecl to the ends theisol' by 2 1s a section vnew of the some termioi o mechonicol algrip, terminsls boil} the body and the terminal to the by Welding or brazing, many (lesirnbls noinls but up to the pres, out time lbey been deficient in one point lbw; i.) bail; on contact area. between the coppczr body and the metal by which they are oltaclieol to the rail is. not sufficient and time nnicss the terminals are most securely I 2! cbecl lo lbs ends of the copper cable they linblo to be pulled off; therefore, by my new and novel construction 1 overcome these objections oncl producc a more eflicient bond from these and other slandpoints.

In Fig", 1 the flexible body portion is designated by numeral 1 and is usually of copper either wire or ribbon. .Tbe terminal mem- 2 are usually made of steel, iron, nickel or some metallic alloy of these in which they predominate, although other metals may be used, and are of two parts; namely, a shelf 3 and a. sleeve 4. Through the sleeve is one or more passages for receiving the body which lerminz-ilo in an enlarged opening 6.

The tsnninal membcr is assembled on the into the recess 6 thereby filling the recess'[ and the some time extending slightlyobove the face 7 of the terminal as designated. by 3. The unsettling of the ends of the body 1 forms a head upon the body which rests in the recess band thereby prevents the body from ulling away from the terminal after instal ation on the rail; in

brazed union between the two parts would fact tests show that the terminal will come away with the body when the bond is pulled from the rail by means of force apphedto the body. The shape of the enlarged passa e orrecess 6 is not material so long as it is arger than the passage 5 or of such-shape that an enlarged head can be formed on the end ofthe body 1, resting on the passage 5 and recess 6 and preventing the body from pulling away fromthe terminal.

The compressing of the sleeve 1 upon the in that it covers all the points oi advantage shown in the other figures and described herein, but it does not require the terminal to be recessed or depressed, it being necessary only to upset or head over the ends of the body cable 1 forming heads 9 upon the upper face of the terminal.

The application of my invention to rails or other conductors to be electrically connected is performed by meansnvell known in the art and for which I make no claims. In Figs. land 2 a bond is shown attached to adjacent railends.

laced in position on the rail and then a eating flame of oxyacetylene, electric arc or.other similar means is applied to the rail surface and bond terminal simultaneously and at the same time a rod or stick of attaching metal is inserted in the flame until the bond terminal and rail are very hot and the attaching metal rod melted and union is made at that point, then the flame and attaching metal rod are moved to an. adjacent point and the process is repeated until the terminal is securely attached to the rail, the attaching means. being designated 'by the numeral 10. This forms an integral union between the bond terminal. the upset body and the rail of highest efliciencv and-one which is porminent.

The use of terminals of iron, steel, nickel or'alloys of such metals and which have a higher melting point and test up harder than copper, has peculiar advantages in that the attaching metal 10 which is usually c'opper, bronze or braze, ctc., forms a stronger union with a terminal composed of such metals than with one composed of copper as bond terminals are usually made. A terqualities' of the copper body.

The bond isfirst "formed up out of the ends of the bodyand antenna minal so made is cheaper than when made 861 of copper. .When made of iron or steel as is usual inmy invention the terminal has i very little if any scrap value' and as it forms a considerable portion of the weight of a. com Jlcte bond, the incentive to steal, the hon s, as is quite general, is practically overcome. f

Upsetting the ends of the copper body 1 and forming an enlarged mass has been found to possess the advantage of protecting the smaller mass of copper below the upset head from the high temperature of the heating flame in that the mass in theupset co er head tends toreceive and absorb t e lieat, thereby preserving the original good It will be observed from Fig. 4. that a area of the recess or enlarged passagecfi is greater than that of the passages 5 and this is of mutual advantage in that the union between the'copper body 1 which entirely fills the enlarged passage 6 and the attach- 7 ing metal used in installing will be greater than if the ends of the body 1 were not compressed andexpanded. This insures an are of contact between the attaching metal and the bond body greater than the cross sect area of the metal opposing thebody and which is very desirable.

The end 8 of the upset body being allowdd to extend slightly above'the face of the terminal has been found of advantage in that it permits the attaching metal to take a better hold on the copper body than if it were below the face of the terminal or just flush. v

Having shown and described my invention, I do not wish to be limited to the exact construction shown and described, as there are variations which can be made and which will be readily recognized by one skilled in the art and which will come within the scope of my invention, but what I do claim and desire to secure by Letters Patent is 1.
