LAMP-BRACKET FOR SEMAPH ORE-SIGNALS.
Specification of Letters Patent.
Patented Mar. 1, 1921.
Application filed May 8 1918. Serial No. 233,187.
To all u; ham it may concern:
Be it known that I, ARTHUR C. KILGOUR, a citizen of the United States, residing at Swissvale, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lamp- Brackets for Semaphore-Signals, of which the following is a specification.
My invention relates to lamp bracketsfor semaphore signals, and has for an object the provision of a bracket which may be attached to the signal post and which permits of adjustment of the lamp in any direction with relation to the post.
I will describe one form of lamp bracket embodying my invention, and will then point out the novel features thereof in claims.
In the accompanying drawings, Figure 1 is a. view showing a lamp bracket B embodying my invention applied to a signal post and semaphore. Fig. 2 is a view showing in perspective the member 5 of the bracket B shown in Fig. 1, and Fig.3 is a similar View of the member 6 of bracket B. Figs. 4, 5, 6 and 7 are top plan views of the bracket B showing the members thereof in various relative positions.
Similar reference characters refer to similar parts in each of the several views;
Referring first to Fig. 1, the reference character P designates a signal post to which is attached a semaphore bearing 2. Journaled in this bearing is a shaft 3 carrying a spectacle 3 to which is attached a. semaphore 4. The parts thus far referred to are of usual and well known construction, and need not be explained in further detail.
Also attached to the bearing 2 is the lamp bracket B comprising two L- shaped members 5 and 6. The member5 has a vertical arm 5 (see Fig. 2) which is secured to the bearing 2, and a horizontal arm 5 which projects horizontally from the signal pole behind the spectacle 3. The other bracket member 6 comprises a horizontal arm 6 (see Fig. 3) which rests on the horizontal arm of member 5, and a vertical arm 6 which holds a lamp L.
It is of course desirable that the lamp L be directly behind the roundels 12 in the spectacle 3, and that it be a certain distance in the rear of the roundels, but as is well understoodthe location of the roundels with respect to the shaft 3 and to the post P varies with spectacles of different designs. It is desirable, therefore, that the lamp be so mounted that it can be moved toward and away from the bearing 2, and toward and away from the spectacle 3. It is furthermore desirable that the lamp be so mounted that it can be turned on vertical axes so that the beam of light can be projected in any desired direction. By constructing the bracket B so that the lamp. can be adjusted in any of these manners, brackets of the same design can be used with a large number of spectacles and bearings'of different designs and under numerous different conditions. I accomplish this by constructing the bracket B of the two members 5 and 6, and by providing a novel means for adjustably attaching the two horizontal arms of these members together.
The vertical arm 5" of bracket member 5 is provided with a longitudinal slot 7 adapted to receive bolts 7 by means of which this member is attached to the semaphore bearing 2. The slot 7 of course permits of vertical adjustment of this member with respect to the bearing 2 and so with respect to the spectacle 3, whereby the lamp and the bracket as a whole may be adjusted vertically with respect to the bearing 2. The horizontal arm 5 of this member 5 is provided with a plurality of transverse slots 8, which slots are preferably, though not necessarily, disposed at an angle of about 45 tothe edges of the arm. I
The horizontal arm 6 'ofmember 6 is provided with longitudinal slots 9 these slots being preferably, though not necessarily, two in number as shown, and preferably parallel with the long edges of the arm.
The vertical arm 6 of this member constitutes a holder to retainthe lamp L in place in the usual manner.
The two members 5 and 6 of the lamp bracket are held together by bolts 10, each of which passes through one of the slots 8 in member 5 and one of the slots 9 in memher 6.
The arrangement of the slots 8 and 9 in the two bracket members permits of adjustment of member 6 with respect to member 5 through a wide range in any direction in a horizontal plane. For instance, the horizon tal arm of member 6 may be placed substantially over the entire horizontal arm of member 5, as shown in Fig. 4:, so that the lamp L will be comparatively close to the ment provided for by slot 7, permits the lamp to be placed directly behind the roundels 12 inspite of wide variations in the position of the roundels with respect to shaft 8*. The member ,6 may be swung through a wide angle with respect to member 5, as indicated byFi 6, so that the beam of light from lamp 1 may be projected in any desired direction with respect to the bearing 2. The lamp may be moved toward and away from the spectacle by moving member 6 transversely with respect to member 5 as indicated in Fig. 7 Ihis adjustment permits the lamp to be located at the same distance from the spectacle in spite of the fact that the space between the signal post and the spectacle varies with signals of different designs. Of course, various combinations of these adjustments may be employed to meet the requirements of any condition which mayarise.
vAlthough I have herein shown and described only one form of lamp bracket embodying my invention, it is understood that various changes and modifications may be made therein withinthe scope or" the appended claims without departing from the spirit and scope of my invention.
, Having thus described my invention, what I claim is:
1. A lamp bracket for semaphore signals comprising a member attachable to the signal post and having an arm projecting from the post, a second member having an arm cooperating with-the said arm on the first member, a plurality of transverse slots in one arm and a longitudinal slot in the other said arm, a bolt passing through said slots for attaching said members together, and means on said second member for attaching a lamp thereto. I
2. lamp bracket for semaphore signals comprising a member attachable to the Sig nal post and having an arm projecting from the post, a second member havingan arm cooperating with the said armon the first member, plurality of transverse slots in one arm'eand aiplurality of longitudinal slots in the other said arm, a bolt passing through. one of the slots in one arm and one of the slots in the other arm for attaching said members together, and means on the second member for attaching a lamp thereto. f
3. A lamp bracket for semaphore signals, comprising a member attachable to the signal post and having an arm projecting from the post, a lamp-carrying member having an arm cooperating with said arm on the post member, a plurality of transverse slots in one of said arms and a longitudinal slot in the other said arm, and a bolt adapted to pass through any part of any one of said transverse slots and any part of said longi tudinal slot to clamp said members together.
4. A lamp bracket for semaphore signals, comprising a member attachable to the signal post and having a horizontal proj ecting from the post, a lamp-carrying menther having a horizontal arm cooperating with said arm on the post member, slots in said two arms, and a bolt passing through said slots for attaching said second member to the first and permitting adjustment oi the second member with relation to the firs" in any direction in a horizontal plane.
5. A lamp bracket for semaphore signals, comprising a member attachable to a signal post and having an arm projecting from the post, a lamp carrying member having a horizontal arm cooperating with said arm on the first member, and means associated with said arms for attaching the lamp mem her to the other member and for permit ting adjustment of the lamp member with relation to the other member in any direction in a horizontal plane.
In testimony whereof I affix my signature in presence of two witnesses.
