W. F. PERSONS. AUIOIVIOBILE LAMP. APPLICATlON FILED OCT. nu ma Patented Apr. 3,1917.

mm mo a citizr r'can be ma 3 is a detail sectional view F; PnnsoNs', of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented. a certain new and useful Improvement in Automobile amps, of which the following is a full clear, and one ct description, reference being had to the accompanying drawings.

This invention relates generally to lamps and more particularly to an automobile headlight lamp.

' The object of the invention is to improve c it known that I, l/VILLIAM theconstruction of automobile headlights particularly withu'efcrence to the manner of securing the glass and reflector to the body of the lamp.

ll ith this object in view the invention consists essentially in constructing the body of the l holding ring curved along its inner edge to engage the glass and flanged along its outer edge toembrace the body portion of the lamp, the glass holding ring being secured by means of a divided clamping ring adapted to embrace the glass holding ring and the outer portion of the lamp body.

The invention consists tails of construction all of which will be :t'ully described hereinafter and pointed out in the appended claims.

In the drawings forming a part of this specification l have illustrated one embodiment of my invention, but it will be under stood that certain changesor modifications de within the scope 7 111 these drawings Figure l is a face view of an automobile lamp embodying my invention, parts being broken away to illustrat-c certain details of construction; F ig. is a vertical longitudinal section of the lo. 13' Fig. is a detail perspective view of the clamping ring; Fig. at is a sectional persp :tive of the glass holding ring; Fig. 5 illustrating the means for fastening the ends of the clampmg ring; and Fig. 6 is an enlarged detail sectional View illustrating the relative positions of the various parts when properly assembled.

Specification of Letters Patent. Application filed October is, 1916.

upon thls also in certain dc-- of the claims.

28 carried in the end rammed Apr. 3, 191 7. Serial No. 126,264.

In carrying out my invention I employ an outer shell or body 10 which may be of any shape desired, the forward outer edge thereof being rolled downwardly at 11 and inwardly at 12, the portion 12 being flat and at right angles to the portion 11 as most clearly shown in Fig. 6. A slight shoulder the lam body, and this flange of the reflector is pre erably formed with an annular groove or recess 16 in which seats the packing ring 17, of any suitable material; and resting packing ring is the circular glass plate or glazing l8.

In practice, prefer to soposition the anthe reflector with its packing ring, I, employ a continuous glass holding ring 19,

the inner portion thereof being curved as shown at 20 so as to contact with the glass adjacent its outer edge, and the outer portion of this ring is flanged as shown at 21 in order to embrace the outer edge of the lamp body, and between the flanged portion 21 and/the curved portion 20 there is formed an inwardly extending shoulder 22 which is adapted to contact with the inturned edge 12 and properly position the glass holding ring.

glass holding ring against displacement I provide a clamping ring 23 lhvided at 24 and having upset- ends 25 and 26, the end 26 being shaped to receivev the end 25 therein and provide a perfectly smooth joint. For the purpose of drawing the ends of the clamping ring together and binding the entirh ring as a whole tightly about the lamp body and glass holding ring, I employ a screw 27 working in the threaded member 25, and if desired' a similar shaped member 29 may be inserted in the offset end 26 for the purpose of strengthening the same and through which the screw works as mostolearly shown in Fig. 5.

The clamping rin is curved or of such cross sectional shape as to embrace the shouldered portion of the glass holding ring and also the shoulder 13 upon thelamp body, and it is obvious that when the ends of: the ring are drawn together and the ring as a whole contracted it will be firmly bound upon the lamp body and all of the parts will be securely fastened in their proper positions.

A. lamp constructed as herein shown and described is easy to .nianufactru'e, and the parts can be quickly and easily assembled and fastened or untastened and separated, and all of the parts so coact and cooperate one with the other, as to insure accuracy of adjustment in the final manipulation.

Having thus described my invention, what I claim is:

1. In a'lamp, the combination with a body portion, of a reflector arranged therein, a glass in advance of said reflector, a glass holding ring contacting with said glass, and an exterior clamping ring engaging and embracing an edge of the glass holding ring and body ofthe lamp.

2. 'In a lamp, the combination with a body portion, of a reflector positioned therein, a glass in-advance of said reflector, a sheet metal glass holding ring contacting with said glass adjacent the outer edges thereof, and a divided exterior clamping ring adapted to engage the glass holding ring and lamp body.

In a lamp, the combination with a body portion, of a reflector positioned therein, a glass contactingwith said reflector, a continuous flanged glass holding ring contacting with said glass, a divided exterior clamping ring adapted to engage said glass hold ing ring and the body of the lamp, and means for contracting said clamping ring upon said glass holdlng ring.

In a. lamp, the combination with a body portion, of a reflector positioned therein, a, glass in advance of said reflector, a flanged sheet metal glass holding ring contact-111g with said glass adjacent its outer edges, a divided exterior clamping ring adapted to engage the glass holding ring and lamp body, the ends of said divided ring being upset, and a screw working in said upset ends for drawing the same together.

In a lamp, the combination with a body portion, of a reflector and glass positioned therein, a continuous glass holding ring adapted to embrace. the outer edges of the lamp body and contact with the glass, and an exterior clamping ring adapted to engage the glass holding ring and lamp-body.

(3. In av lamp, the combination with a. lamp body having a reflector and glass positioned therein, of a continuous flanged glass holding ring adapted to contact with the glass" and embrace the outer edges of the lamp body, and an exterior clamping ring adapted to engage the glass holding ring and the lamp body.

7. In a lamp, the combination of a body portion, of a flanged reflector positioned therein, a glass positioned upon said reflector, a continuous, flanged, glass holding ring contacting with said glass and embracing the outer edges 01'' the lamp body, a divided exterior clamping ring adapted to engage the glass holding ring and lamp body, and

7 means for drawing the ends of said divided ring together.

8. In a lamp, the combination with av body portion having an inwardly rolled front edge, of a flanged reflector, a glass, and a glass holding ring, said ring being flanged, shouldered and curved, a divided clamping ring curved in cross section, and means for contracting said clamping ring.

In testimony whereof, I hereunto ailix my signature.

'WILLIAM F. PERSONS.
