sisting of the carbon guide-tube closed at one end, the feed-mechanism chamber attached at one end to the other end of the guide-tube, a transparent enclosing bell bearing against the other end of the chamber, a dash-pot fixed on the end at one side of the chamber, a piston working in the dash-pot and a rod fixed to the piston passing into the mechanism-chamber to operate the feed-device therein and passing outwards to the regulating-mechanism, the whole forming an enclosed chamber in which any transference of gases has to take place through the dash-pot. (3.) The means for fixing the enclosing bell in position, consisting of a fitting fixed on the end of the bell opposite to its mouth and provided at its outer end with a recess, a loop or double yoke having a projection bearing in the recess and side arms, and spring bolts hung on the lamp-frame, and a swivel joint connecting the side-arms of the yoke to the spring bolts. (4.) The carbon-holder, consisting of a split cylinder forming tongues adapted to grip the carbon and spring contacts, riveted at one end to the tongues, and bearing at the other end on the carbon guide-tube. (5.) The negative-carbon holder, comprising the split socket with tapered exterior surface and an internally tapered bush fitting on the tapered jaws, and having a pin adapted to pass through the slits in the socket. (6.) The means for conveying current to the movable carbon, consisting of a contact roller, a link carrying the contact roller, and a piece fixed to the feed-devices that raises the roller off the carbon when the feed-devices are operative. (7.) The shunt cut-out device, comprising a cut-out lever, fulcrummed to an insulating ring on the main tube, and capable of being engaged by the main lever, an insulated spring contact-plate forming with the cut-out lever the cut-out switch, and a shunt coil, one end of which is connected to the negative terminal of the lamp, whilst the other end is connected to the spring contact. (8.) The regulating-mechanism for arc-lamps, consisting of a lever, curved guide-surfaces on the lever, cords or bands fixed to the lever and bearing on the guide-surfaces, and the regulating device and the feed-device connected to the cords. (9.) The method of suspending the lamp, consisting in suspending the frame from the crown, the lamp from the ceiling, and the case from the crown by springs, straps, or the like.

Claims.—(1.) An arm for chronological-chart-drawing instruments having a pivot-point at one end and a series of divisions concentric of said pivot-point, said series of divisions being divided into a number of sets for the purpose set forth. (2.) An arm for chronological-chart-drawing instruments having a pivot-point at one end, a series of equal divisions g radiating from said pivot-point and extending one beyond the other and offset from one another, and a series of equal divisions concentric of said pivot-point and subdividing said radial division, substantially as described and for the purpose set forth. (3.) An arm for chronological-chart-drawing instruments having a pivot-point at one end in line with one side edge thereof, a series of divisions g radiating from said pivot-point, and extending one beyond the other along both side edges of said arm and offset from one another, the radial divisions at one side edge being of greater length than the division at the other side edge, and a series of equal divisions concentric of said pivot-point and subdividing correspondingly said radial divisions, substantially as described and for the purpose set forth. (4.) An arm for chronological-chart-drawing instruments having a pivot-point at one end and a scale at each edge of one side thereof, each of said scales comprising large divisions subdivided by smaller divisions, the smaller divisions of said scales being equal and the larger divisions of one scale differing from the larger divisions of the other scale, substantially as described and for the purpose set forth. (5.) A chronological-chart-drawing instrument comprising a base, a detachable rigid arm pivotally connected to said base so as to allow of the introduction of a chart-blank between the arm and base, and suitably divided and subdivided, and a marker carried by said arm and movable longitudinally thereof, substantially as and for the purpose set forth. (6.) A chronological-chart-drawing instrument comprising a base, a detachable rigid arm pivotally connected to said base so as to allow of the introduction of a chart-blank between the arm and base and suitably divided and subdivided, a flexible indiarubber block gripping and movable longitudinally of said arm, and a marker carried by said block, substantially as and for the purpose set forth. (7.) A chronological-chart-drawing instrument comprising a base, an arm pivotally connected to said base and suitably divided and subdivided by radial and concentric lines, a flexible indiarubber block gripping and movable longi-
tudinally of said arm, and a marker carried by said block, substantially as and for the purpose set forth. (8.) An arm for chronological-chart-drawing instruments having a longitudinal recess in the exposed face thereof, and a series of strips b, bearing time-scales, carried in said recess, said strips being interchangeable with one another; a hinge-plate 7 pivotally connected to one end of said arm, a thumb-screw 5 for connecting said arm to the frame 4 of a blackboard 3, and a slidable block m, having a notch n and a diagonal hole p for a chalk marker o, all as shown in Figs. 4, 5, 6, and 7, and substantially as described, and for the purpose set forth. (9.) A chronological-chart-drawing instrument comprising a base, an arm pivotally connected to said base and suitably divided and subdivided by radial and concentric lines, a flexible indiarubber block gripping and movable longitudinally of said arm, and a marker carried by said block, the base adapted to support a chart-blank having one or more radial scales, said scales comprising divisions and subdivisions corresponding to those upon the arm, substantially as described, and for the purpose set forth.
