ADJUSTABLE LAMP. APPLICATION FILED AUGJ. I914.

Patented June 15, 1915.

FIRED C. HOVIE, OF NEW HAVEN, CONNECTICUT.

ADJUSTABLE LAMP.

To all whom it may concern:

Be it known that I, FRED C. HOWE, a citizen of th e'United States, residing atNeW' Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Adjustable Lamps, of which the following is a specifi-.

the shaft 13, having a hand wheel 14 upon cation, reference being had therein to the accompanying drawings.

My invention relates. to a new and 1mproved adjustable lamp of that type wherein the lamp may he moved aboutv a'central point, and has for its object, among other things, to simplify and make more positive the construction of this type of lamp with the fewest possible parts.

To these, and other ends, my invention consists in the adjustable lamp, having certain details of constructionand combinations of parts, as will be hereinafter de-' scribed and more particularly pointed out in theclaims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures, Figure l is a fragmentary side view of my improved lamp with the parts within which it is mounted shown in section; Fig. 2 is anend view thereof, partly in section; Fig. 3 is an enlarged side elevation; and Fig. l is an enlarged fragmentary portion thereof, showing in detail the construction and arrangement of the pinion with the disk adjacent thereto.

My invention is particularly designed for use upon automobiles, wherein it is desirable that the rays of light from the lamp may be thrown to any pointwithin'a limited zone about a central point, although not limited thereto, as its adaptability with other mechanismsand inother places is quite apparent.

In the drawings, the fixed part 'to which my improved lamp is connected is designated by the numeral 1, upon both sides of which are the collars 2+2. lVithin these. collars and the part 1 is rotatably mounted the shank 3 of the guide ball at, through which is a. straight slot 5parallel to the axis of said shank.

Partly surrounding the guide ball 4, and

maintaining a movable contact therewith, is

the cup 6, having an irregularlyshaped opening 7 therethrough with a projecting lip 8 thereon parallel with and adjacent to the edge 9 of said opening. Fixed within said opening is a plate 10, the outer edge of Patented June 1 55, 1915.

cured to the cup 6 by the bridges 12 so that the edge of the plate 10 containingthe teeth 11; is substantially parallelwith, the face 9 of the opening 7. Secured to the cup 6 is the lamp body 19-, within which is alamp20.

Rotatably mounted within the shank 3 is one end and a pinion 15 upon its opposite.

end, the teeth of said pinion meshing into the teeth 11 and thereby moving the cup 6 about the center of the ball 4; as the shaft 13 is rotated, during which time the stud. 16

trayels in the slot 5 guiding the said cup 6. This engagement of thepin and slot always insures the retention of the cup 6 in any of its several positions. Endwise movement of the pinion 15, whereby it may become disengaged from the teeth 11, is prevented by the washer 17 thatis rotatably mounted upon the screw 18,'threaded into the shaft The thumb screw is threaded through the spindle 3 and impinges against the shaft 13 s0 as to lock the shaft against rotation and hold the lamp in any of its se'iieral posi tions.

'As minor changes and alterations can be made within my invention, I would therefore have it understood that I do not limit myself. to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of my. invention.

.Having described my invention, what I claim as new and desire to secure by'Letters Patent, is I 1. The combination with a globular member; of a cup member with an irregularly shaped opening therethrough partly surrounding said globular member and having a movable engagement therewith; a toothed plate within said opening; means for securing the same so that there is anopen space aroundthe entire edge thereof and inside the edge of the opening in said cup member, and means for moving said cup about said globular member, comprising a rotary shaft having a member thereon operatively engaging said toothed plate.

2. The combination with a globular mem ber; of a cu member with an irregularly shaped opening therethrough partly surrounding said globular member and having a movable engagement therewith; a plate Within said opening having teeth around the entire edge thereof; means for securing said plate to said cuo member, and means for moving said cup about said globular member, comprising a rotary shaft having a. member thereon operatiyely engaging said plate.

3. The combination with a globular member; of a cup member with an irregularly shaped opening therethrough "partly. surrounding said globular member and having a movable engagement therewith; a toothed plate Within said opening; means for securing said plate to said globular member so asto have an opening entirely surrounding said plate and of substantially uniform 'vvidth; means for moving said cup about said globular inemberyeomprising a, rotary shaft having a member thereon operativeiy engaging said toothed plate.

l. The combination with a globular member; of a cup member with an irregularly shaped opening therethrongh partly surrounding said globular member and having a movable engagementtherewith; a plate Within said opening having teeth in the edge thereof; means for moving said cup about said globular member, comprising a rotary shaft having a member thereon operatively engaging said plate; and means, as a member acqacent to Sfllfll pinion, for holding the same against endwise and lateral movement.

5, The combination with aglobular men1- ber; of a cup member with an irregularly shaped opening therethrough and a shoulder parallel therewith partly surrounding said globular member and having a Inovable'engagement therewith: a toothed plate within said opening; means 101' moving said cup about said globular member, comprising a rotary shaft having a member thereon operatively engaging said toothed plate; and means for holding said pinion in engage-- said mein shoulder.

globular metre ber; of a. cup member with an irregularly shapedopening therethrongh and a shoulder parallel therewith partly surrounding said globular member and having a movable engagement therewith; a plate within said opening having teeth in the edge thereof; means tor moving said cup about said globib lai member, comprising a rotary shaft having a member thereon operatively engaging said plate; and means for holding said pinion in engagement with the teeth in said plate, said means comprising a disk having a rotary contact with said shoulder and and in relation to said pinion so as to prevent axial movement thereof.

inent with the teeth in said 1:: ber having contact with said 6. The combination Wit; a

having a substantially straight slot therein; of a toothed cup member; a member on said and means ifor moving said (311p member about said globular member, said means comprisinga rotary, toothed, member hav ing engagement with the teeth in said can member.

8. In combination, a globular member having a substantially straight slot therein. and a hollow shank connected therewith; ot a toothed cup member; a member on said cup member projecting into said slot and having an operative engagement therewith; means for moving said can member about said globular member, said meanseomprising a shaft rotatably mounted in said shank; and pinion fixed 'thereto having a toothed engagement with teeth in said cap-member.

In testimony whereof I ofia my signature in presence of two Witnesses.
