.Beit kinown that ."I, Jonnhlannnn, -a citizeny of the UnitedA States, residing at, lIrvington,.in the county-.,oEsseX Aand State of New Jersey, have..invented.cer.tain new .and .useful Improvementsin Pyrometers orfThenmo-B atteries; and .I do' hereby declare the. iollowing. toA bexa full, clear,and exact description ,of theinvention, such as will enable lothers skilled th'e art to whichit appertains to make zand use the same, reference being had. to the accompanying drawings, and. to characters of. reference marked thereon, .whichorm .a. part of this specication.

.The present invention has referencegen eralbly, to .a .novel .and .simply constructed devlce orapparatus in the form Aof a pyrometer.

general character -hereiua couple, .adapted to be resent invention has for its principal ob]e'ctx to provide an a paratus of the er tmore Vfully specified, in the form of a simply constructedand eiicient heat-collector andthermoarranged in electric circuit with a galvanometer, and bymeans of which the current induced by the various .degrees oitemperature ,and` caused by thecollected heatmays within said collector may lbe made to -produce corresponding movements of the energizing -coil and the index-hand of. a. galvanometer.

:Other objects ofthis inventionnot at this time more particularly enumerated willbe .clearly understood, from. the following de- -Fig is a transverse vertical section,

- which :is suitably sentation of a heatcollector showing one embodiment of the, principles of the present invention;F ig. 2 is 1.a longitudinal vertical section ofthe same, taken centrally through the.heatcollecting.tube of the device; and taken online 3 3 in said.Fig. 2, looking in the .direction of the .arrow said View being made Aantan enlarged scale. Fig. 4 is a detail-'longitudinal vertical section, on an enlarged-scale, said section being taken on line bottom-.view of .a base-plate upon w ich the heat collecti-.ugtube .is adapted to be secured: and'Fig. 6. is a face view of the heatray. collecting end-portion of the heat-collectingx tube, provided witha removable reducing shutter or. slide.

f Similar characters. of v reference. are employed in .all vof the above. described views, to` indicate. corresponding parts.

-Referringnow to Figui of theV drawings, there-areshown herein two circuit-wires, 6o

rand 66, which are suitably .attached to the binding-posts v67 and 68 of a base 69.1nade from suitable insulating material, and upon mounted the herein-before mentioned heatrays collector. This collector consists, essentially, of a tubular body 70, secured at its one end-portion upon said base 69, by means of screws 71 and 7 one end of.. the sald body ZO being left. open, as

.at 7.3, while its other end is closed, preferably byfmeans cfa disk 7i made of suitable insulating material. Vithin the said tubular. body 70, at a pointY near its closed end, is .a thermo couple. This thermo couple consists, essentially, .of post 7 5' made from suitable insulating material which is surrounded'by a chambered or tubular casing 76,. also of suitable insulating material, the lower portions ,of said postl7 5 and the casing 76l extending through an opening 77 in said tubular .body.'0" and being secured to the base .67 byf means of a screw 78, or other suitable fastening. means. `Suitably riveted upon the opposite sides of saidlpost 7 5', or Aotherwise secured thereto, are contact-mak,- ing metal .plateflike members 79 and SO with which. 's connected a frame-like met-al member or element, as 81, which is formed with suitably shaped and angularly disposed heat-ray collecting ritiles or projections, as 82, which are preferably struck' "up" out of the metal of which the member or element 81 is made. Connected with the binding post 67, and suitably secured `thereto by means of a binding screw 83, is a circuitwire 84 which passes through aperforation or hole 85 in the basek 69 and i'nto and through the chambered.' or tubular casing 76, said wire leading out therefrom and being suitably connected with the plate-like member 79. In like manner,` there is conlected with the bindingv post 68, and Asuitably secured thereto by means of a binding screw 86, a circuit-wire 87 which passes through a perforation or hole 88 in the base 69 and into and through the chambered or tubular casing 76, said wire leading out therefrom and being suitably vconnected with the plate-like member 80. In this manner, the thermo-couple may be properly arranged in circuit with a galvanometer, as

will be clearly evident; and, whereby the heat-rays which are collected by the rillies 82 will produce'an electric current in the completed circuit, and said current will be conveyed to the galvanometer. Back of thel saidrthermo-couple' is a concave mirrorv89, Iliade of silver, or any other seuitablematerial of greatradlatmg efficiency, said mirror having suitably secured upon its back,

by means of solder 90, or other suitable fastenxing means, a member 91 which is provided with an upwardly extending screwthreaded shank 492.?.l This shank 92 Lextends through a slide, such as 93, which is suitably itted in and is slidably arranged in the tubular body 70, the upper screw threaded end-portion of s id shank 92 through a slot 9 in the said tubular-body 70 and having arranged thereon a binding or tighteningV nut or ingerpiece-95. The said slide 93 1s also provided with a guidingstud, as 96, which extends upwardly and is slidably disposed inrjsaid slot 94, so as to retain the slide in"` its proper sliding relation, and to properly retain the mirror in its position for receiving the rays of heat and by reflection focusing said rays upon the collecting riiiles ofthe thermo-couple. This arrangement of these several parts also permits of an adjustment of the mirror, back and forth, to a certain degree within the tubular body 70, as will be clearly evident. The said tubular body 70 is also provided at its.. open end-portion 'with forwardly extendingfarms or rods, as 9T, which carry upon ltheir free ends Va perforated shield, as 98, through which the heat-rays' are projected into said tubular body for distribution uponV the mirror from which the rays are reliected directly upon the rilles of the thermo-couple. Within the said tubular body 70 there may also be aralso extendingjv f rangedii'al ring-shaped device or perforated shield 499 .which Aprevent-s anyfaflse :currents Vof air from. radiating upon] the thermocouple. If desired, the opening in the sliield 98 maybe made smaller b the arrangement over saidv shield of a suitable shutter 100 which is provided with a reducing opening 101, the said shutter being provided with a iingerpiece 102, and being removably arranged upon saidshield 98 by an Varrangement of fingers, as 103, with which the said shield may be provided. Of course .it will be understood that any suitable tornir of reducing shutter maybe employed, and' any other suitable means ma be used with the saidshield and shutter or connecting said shutter with said shield. f I The "workings and operations of the several parts of the apparatus willbe clearly understood from the foregoing descriptiony and from. aninspecton of the severaly Ifigures of the dra-wings, and need, therefore, not be further described. Y

I am aware that changes may be `made in the general varrangements and combinations of the various devicesand parts, as well as in the details of the construction of the same,

without departing from the scopeof the present invent-ion las., set forthfin the foregoing specication, and as defined, inthe claims which arenapp'ended thereto. .Hence, I do-Y not lixnitimyllpresent invention to the exact arrangements and combinations of the devices and "parts as described Ain the said specificatiom'nor do I confine myselfto the eXactQdetailsof ythe construction of thesaid.,
