UNITED STATES JAMES STIMPSON, OF BALDWINSVILLE, MASSACHUSETTS.

IMPROVEMENT IN STREET AND PARK LAMPS.

Specification forming part of Letters Patent No. 189,514, dated April 10, 1877 application filed March 21. 1877.

To all whom it may concern:

Be it known that 1, JAMES STIM'PSON, of Baldwinsville, county of Worcester, and State of Massachusetts, have invented an Improvement in Street and Park Lamps, of which the following is a specification:

This invention relates to improvements in street and park lamps; and consists in a swiveling lantern-cage having its supportinglever pivoted to a post, so that the lever and lantern may swing from their upright positions to a position where the lamp or illuminating medium may be placed into or re moved from the lantern, thereby obviating the use of a ladder.

Figure 1 represents one of my improved street-lamps in side elevation. Fig. 2 shows the lantern-cage and lever swung down, an Figs. 3 and 4 show modifications.

The post a may be made of iron or wood, and may be of any suitable height and pattern.

The lever b, to support the lantern-cage 0, has at top a fork, d, to which the lantern is swiveled.

This lever is pivoted at e, and, as shown in Figs. 1 and 2, it has a weight,f, to counterbalance the weight of the lantern.

The lantern may be made of any suitable shape or material, and may receive a lamp containing any usual burning material or a candle.

The lever and lantern are locked in upright position by means of a locking device, the main part of which, in this instance, is shown as attached to the post.

This locking device is composed of a slide, g, provided with bars or portions to be engaged by a hook, it, on the lever, and a hook, i, on the lantern, when the latter is in upright position, as shown in Fig. 1.

a stud, l, that enters the bent lower end of the slide.

Instead of the devices shown as employed to hold the lever and lantern in upright position, I may employ a reciprocating spring-held pin, to enter ahole in the lever, and a second one to fasten the lantern and its holding-fork together.

Instead of using the counterbalancingweight, as shown, I may attach to the lower end of the lever (it terminatingjnst below the pivotal point e) a cord, m, which in turn is adapted to be connected with either a strong spiral spring or a weight. (Not shown.)

This lever may be provided with teeth 11., adapted to engage with and to be operated by means of a pinion, 0, turned by a handle, 19, applied to the shaft of the binion.

A pawl, r, acting against a ratchet, prevents the lever from moving back too far.

I may fasten to the lever a pivot, 8, adapted to fit into openings in the post, and by applying a handle to the pinion, as at t, the lantern (the lever being weighted or otherwise counterbalanced) may be raised or lowered in the are of a circle.

I claim 1. The combination, with a lamp-post, of a pivoted lever and lantern, substantially as and for the purpose described.

2. The pivoted lever, lantern, and post, in combination with a locking device to hold the lever in an upright position.

3. A locking device, in combination with a lantern-cage and its carrying-lever, to operate substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES STIMPSON.
