HEADLIGHT AND THE LIKE.
Application filed April 2, 1924. Serial No. 703,806.
To all whom it may concern- Be it known that I, FRnnnr-ucn G-nonon PIPER, a subject of the King of Great Britain, residing at Winchester, in the county of Hants, England, have invented certain new and useful Improvements in Headlights and the like, of which the following is a specification.
The invention relates to anti-dazzle headlights for motor cars and like lamps provided with axially movable lamps adapted to be shifted relatively to the foci of the reflectors by means of wires operated from the dash board or other position remote from the lamp by a push rod. lVith such apparatus as hitherto constructed considerable difliculty is encountered in accurately adjusting the wires initially and also in readjusting them after they have been in use for some time. There is also difficulty in inserting and securing the wires in ends of the sliding lamp holders.
According to the invention the push rod is of such form that the wire may be passed through it to the rear Where it is accessible so that it can be adjusted either as regards length or tautness initially or at any other time. \Vhen two or more wires are used it is preferred to provide a separate push rod for each, so as to permit of independent adjustment f each wire, means being provided, when desired, by which the push rods may be operated simultaneously after the wires have been adjusted. The invention also includes improved means for tacilitating the securing of the ends or the tubular casings for the wires and also for facilitating the insertion and securing or removal of the ends of the wires in the ends of the sliding lamp holders.
In the accompanying drawings Figure 1 is a plan, half in section, of the lamp operating device which is mounted on the dashboard. I
Figure 2 is an elevation partly in section of the lamp fitting.
Figure 3 is a cross section of a detail on III-III, Figure 2.
In the form illustrated, which is suitable for example for the simultaneous operation of two lamps, two push rods 1, each having a bore 2 throughout its length large enough to permit of the passage of a wire 3 are mounted on the flange 7 of a knob or handle 8, which is preferably removable from the flange being, for instance, screwed into the flange. The flange 7 has square holes to receive squared parts 9 ot the push rods 1 so that the rods cannot rotate. The adjacent ends of the rods 1, which project behind the flange '7 are screw threaded to receive nuts or caps 10 which draw the rods 1 until collars 11 on them abut against the opposite side of the flange 7 Vhen screwed caps 10 are used they are recessed inside to allow a short piece of wire to project beyond the ends of the rods 1, so that the wires 3 may be gripped by pliers when it is desired to adjust or to tighten the wires after being in use for some time. The wires 3 are secured to the rods by grub screws 12 which may pass through the collars 11. The rods 1 slide in tubular guides 13 which may be in the form of bolts having bores large enough to receive the rods 1. The guides 13 are screw threaded externally throughout their length, and are passed through the dash board 14: until the heads 15 abut against the board or against washers or a metal plate 16 and are secured by nuts 17 which abut against the opposite side or against washers or a single metal plate 18. The ends 19 ot the bolts 1?) remote from the dash board lat are slightly tapered and provided with several saw cuts 20. .The ends of the tubular casings 21 for the wires 3 are inserted in bores of these ends 19 of the bolts 13 which are then tightened by nuts 22 so that they grip the casings 21 firmly.
The sleeve 23 on each headlight which receives the .slidable lamp holder 24 is fitted with a cap 25 having a screw threaded boss 26 which is provided with saw-cuts and a nut 27 so that it grips the adjacent end of the tubular casing 21 firmly.
Each sliding lamp holder 2-1 is provided with an end disc 28 which has a radial slot 29 passing fromthe centre of the disc outwardly to a large eccentric hole 30. The wire 3 is provided with two collarsSl spaced apart or with a nipple consistingoi" two collars 31 separated by a thin neck 32. \Vhen the wire 3 is to be secured to the lamp holder 24L the nipple is inserted in the large hole until the neck 32 is opposite to the slot 29. The nipple is then moved laterally to bring the neck into the central position with the collars 31 one on each side oithe disc 28. The wire 2) can thus be easily inserted or removed by merely removing the end cap25 of the sleeve 23.
By means of the invention an unskilled person can easily renew or adjust the wires and easing.
In applying the invention to head lights which have no hole in the rear of the lamp casing 33, a hole is made to receive the lamp operating fitting. A flanged boss 34 is socured to the casing 33, the boss being split or provided with saw cuts, screw threaded and fitted with a nut 35 so that it will grip the sleeve 23 of the fitting.
It will be understood that when the lamps are to be dimmed the knob 8 is gripped by the driver and thrust inwards towards the dashboard, so that the push rods 1 thrust the wires 3 along the casings .21 and slide the lamp holders 2% to move the lamps out of the foci of the reflectors. The lgiarts are shown in this position in the drawings. \Vhen light of full power is required the knob 8 is pulled out so that the lamps are again brought into the l oci of the reflectors. Light of intermediate power is obtainable by shifting the lamps into intermediate po sitions.
Each push rod may be provided with a separate knob if desired so that the lamps may be operated independently 1. A means for adjusting the lamp holder of an anti-dazzle headlight, comprising wire, a tubular casing therefor, a tubular guide receiving the end of the tubular casing, means cooperating with the guide to clamp the casing in said guide, a push rod slidably mounted in the guide and having an axial bore extending therethrough in which the wire may be moved without interference, means carried by the push rod to clamp the wire in the axial bore of the latter, and means remo'vably connected to the end of the push rod for operating the latter.
2. A means for adjusting the lamp holder of an anti-dazzle headlight, comprising a wire, a tubular casing therefor, a tubular guide receiving the end 0-1 the tubular casiiig, means cooperating with the guide to clamp the casing in said guide, a push rod slidably mounted in the guide and having an axial bore extending therethrough in which the wire may be moved without interference, means carried by the push rod to clamp the wire in the axial bore of the latter, a knob for operating the push rod formed with an opening to receive the end of the push rod, a cap threaded upon the end of the push rod beyond the knob, said cap being hollow to permit the end of the wire extending through the push rod and into the cap, whereby on removal of the cap the wire is available for manual adj ustment.
3. A means for axially moving the lamp holder of an anti-dazzle headlight, comprising a wire and a remotely located push rod having an axial .bore extending wholly therethrough to receive the wire, an operating member in which the end .01 the push rod is inserted, and means tor securing the push rod to said member to permit the projection of the end of the wire beyond ztlie connected end of the push rod, whereby said wire is available for manual adjustment without disconnecting .the parts.
