UNITED STATES PATENT OFHCE. LEONIDAS G. WOOLLE¥~ OF MENDON~ N~HIGA~ ELEOTRIO LAMP. SPECIFICATION forming part of Letters Patent No. 241~11~, dated l~fay 3, 1881. Application filed hq~vember ~4, 1680. (No mode0 To all ~vhom it may concern: Be ~ known that ~ LEORIDA8 G. WOOLLEY~ of Mention, in the county of St. Joseph and State of Michigan~ have invented ce~n new S and u~efal Improvemen~ in Ele~ric Lamps; and I do hereby declare ~m ibl~w~g to be a full, drab and exact desc~p~on of the invm> ~on, such as will enable others skilled in the art to wh~h it pertains to make and ~se it, ~e~ ~o erence bring had to the accmnpm~ying draw- ings, which form part of this spedficagon. My inven~on relates to an improvement ia dect~c lamps ; and it conds~, fi~t, iu a pc- ]ygonal lamp-~ame which ~ suspended in posb ~ ~on by a se~es of oppodng sp~ngs appl~d to its cornm% wh~h sp~ngs neu~alize thej arrin g and shaking movements in such a manner as to adapt the lamp for use as a head-light oua locomo~ve; second, in the combinagm~ of the ~o carbon~oldeB a sliding collar placed thereon, a damping-lever pivoted upon the caller and provided with an armatur% a device lbr regu- la~ng the d~tance the outer end of the lever shall ~se, and an dec~mmagnet lbr raising 2S the leve~ collar, and carbon~dder upward ; third, in the combina~on of a ho~zontal hdix and a pro%rated endwismmoving bar or rod~ whid~ extends into the center of the hdix so as to act as an armatur~ and through which 3o the carbon-hdder passes, whereby, wlmn the endwismmoving bar becomes dect~fied by the ~c~on of the magnet~ the bar ~ drawn into the magnet with suffident force to preventthe car- ben-holder by frictional contact ~om drop: 3~ ping downward too ~apidly; fourth, inthe ar- rangement and combination ofpar~ whid~ will be more fully herdnaffer set ibrth. The o~ect of myinven~on is adjus~ng the movement or feeding of the carbons by a very 4o ~mple and inexpcn~ve mechanism, and to dis- pense with aH the wheals, dock-work~ and other such expen~vc devices as have heretofore been used. Figure 1 is a ride deva~on of my inven~on 45 complctm Fig.2 is a ver~cM section through the upper part of the fi’am rework taken a~ fight angles to Fi& 1. Fig. 3 is a detMlview. Fig. 4 is a verffcal sec~on of my inven~on. Fi~ 5 is a detM1 view of the damping device and ~o carbon-holde~ A represents the flame in Which {he lamp is supported, and which may be eiflmr of the tbrm here shown or any other that may be preferred. A~ached to each corner of this fl’ame A is a sp~ng, B, of any desired shape, size, or 55 cmm~uction, and which prevent m~y shaking or vibra~ng of the ~ame whirl, would have a tendency to inter~re with the perker acing of the light. If so pre~rred, the two lower springs may be ed~d ones and the upl>er ones 6o flu>bar sp~ng~ or M1 of the q>~ngs may be of the same construc~on as is here shown. The great o~ec~on her~o~re existing to the use of the electric lamp as a headdight npou locomo~ves has been that thejar~ng and 6~ shaking of the locomo~ve when in me,on are so great that the different parts of the lamp have been shaken and jarred to such an extent that thelamp soon becomeginopera~vm This ~aking has heretofore caused the carbons to 7 ° break and the upper carbon-holder to wo~ so unsteadily that the l~np was practically use- less as a ~comofive head-lighg These o~ec~ons I comI)letdy overcome by SUl)porting the lamp-frame by means of a suit- 7~ able number of springs in an ou~r ~n% C~ <hich may be attached to the ~ont of the locomo~ve or any other object in any suitable manner, and which springs serve to neural ize the jar~ng and shaMng me,on to such 80 an extent that the ~ight ~d almost impem cepfible vibratory movement of the ~ame A causes no inconveu~nce. The ~ame A, as here shown, is supposed iu an outer~ame by memos of four sp~ngs; but i~ is e~dm~t that 85 this ~amc or any other suitable form of ~ame may be suppor~d upon a suitable number of sp~ng~ and which will have to a very great extent the same e~bct, though not as pm%ct a one as whm~ the sp~ngs are applied to the 9 ° corners~ as ]lerc ~lown, Upon the top of the ~ame A is placed the i~on ~ame D, of any suitable shap% and wh~h ~ cast in one cm~nuous piece, so as to form a magne~c conductor between the two magnet~ 9~ Pas~ng down through the center of this Dame is the carbon-holder E, over wh~h~ inside of the ~ame, is placed a preihrably nommagnetic cdla~ F, wh~h slides @rely upon the carbon- holder and serves p~ndpa.lly as a pivot upon ~o~ which the damping-lever G ~ supported. Upon one side of this caller ~ formed a flange~ a~ and the angular end of the lever is eat out so as to fit over this flange and vibrate @edy upon its pivo~ which passes thmug’h the flange. Upon the top of this damping-leveG whid~ may be of S the shape here shown or any other that may be preferred, is secured an armature, G’, so that whenever the current of ~eetN~ty is passed through fl~e magnet I:[ this armature is at- tracted to the pMe of the magnet and the damp- ~o ing device thus li~ed ho~zontMly upward. The end of the damping de~ee which is in contact with the earbon&Nder is so shaped that when the device is vaned upward the ti’ietionN contact of this device agNnst the side of the " ~ 5 carbon-holder will cause fl~e earbon&ohler to be rNsed upward a suffiNent distance to sepa- rate the upper carbon @om the lower one far enough to produeethe are. The outer and long- er end of this damping lever or dev~e is made ~o to catch in fl~e stop I, whid~ is secured to the inner side of the ~ame D, and which stop is placed in such rdafion to thepole of fl~e magnet that as the ~mnping device is being rNsed ho~zontNly upwm’d, carrying the carbon&~d- ~5 er with it, the outer end of the damNng device strikes this stop beibre the re’mature comes in contact with the pNe of the magneN and as the damping device continues to move upward it is tilted or turned Nighty upon its pivot c 3° in such a rammer as to r~easei~ hNd upon fl~e earbon~olde5 and thus let the earbowh~der drop downward, while the damping device ~e- mNns suspended agNnst fire pole of the magnet. This stop I maybeof anysnitablefonn, 35 m~d willbe prel~rablyprovided with a set-screw, so as to bear agNnst the outer end of this damping device, and thus cause it to release the ea~ bon~Nder a~ any point duNng the upward travel of the dmnping device, and in this man- 40 net regulate the distmme whi~ the carbon- holder shall be rNsed upward. When the damping device releases its hohl upon the earbon&Nder the hNder woMd drop its fi~H length down through the Kame were ib 45 not that stone other means are provided so as to regulate the speed at whi~ the hNder shM1 move downward by its own gravity. Secured h~ the ~ame D at right an~es to the magnet It is placed a hNix, J, which, instead of b~ng 5° provided with a sta~onary pNe like the magnet ~, is made hN~w, and its armature is tbrmed by the endwis~moving bar or rod ~, which has a hole made through its center tbr the earbon~Nder to pass through. Upon the 55 top of th~ armature ~ placed a suM1 ~om roHeswh~h bears agNn~ the edge of the flange upon the verfieNly-moving eolla~ and which roller prevents any endwise movement of the armature L until the vertically-moving eNlar 60 has been raised to ~at poin~ by the ti~ict~n - ~amp where the frietion-dampr~eases i~ hNd upon the earbon-holde~ when the armature~ bNng ~ee to move, is drawn endwNe into the helixso as to exert just a suffiNent frietionM con- 65 taetagMnsttheMdeof theearbon-holdertopre- vent ~ ~om moving too rapidly by ~s own gravity. The hale or opening through this armm tare for the carbon-holder to pass through is made Mighty ~ongated~ so that when the armature is not drawn into the h~½ i~ exerts no 7 ° power upon the carbon&olden At~ehed to this armature at any suitable point is a sm~l spring of sM~Me shape~ size, or eonstrnetion, and which moves the armature outward as soon as it is le~ ~ee to move. 75 One of the wires is connected wifl~ ~e magnet H, and the other one with the lower earbon&oldc~ as N~own in Fig. 1. The two nag- nets~ ~[ J, are connected by means of their wires or in any other sNtaNe mmmer with 8o I re wst. h°ene @amtI ethr°nDgh’ an~h ~h~am ee ~urrena ts she wP
