JOSEPH P. sTRAUss, OP CHICAGO, ILLINOIS.

RECONNOITERING APPARATUS.

To all whom it may concern:

Be. it known that I, JosnrH B. STiiAUss, a citizen of the United States, residing at Chicago, in the county of Cook and State" of Illinois, have invented a certain new and useful Improvement, in Reconnoitering Apparatus, of which the following is a specification. i i

This invention relates to portable searchlights and has for its Object to provide a new and improved device of thisdescription. The invention is illustrated in the'accompanying drawings, wherein- `Figure 1 is a side elevation showing one form of device embodying the invention;

Fig. 2 is a rear view of the device shown in Fig. 1, with the lamp removed; i

Fig. 3 is a view of the platform and a portion of the movable arm is seen looking in the direction of the arrow on line 3-3 of Fig. 1;

Fig. 4 is a partial plan view `in `part section, showing the Operating mechanism;

Fig. 5 is a sectional view taken on line 5-5 of Fig. 4. r

Like numerals refer to like parts throughout the several figures.

In the construction shown, I provide two pairs of wheels 1 and 2, each pair having a connecting axle, the wheels 1 `acting as the front wheels, and the wheels 2 as the rear wheels. These wheels are adjustably connected together so `that they may be moved relatively to vary the distance between them. In the construction shown, the two sets or pairs of wheels are connected by the

frame pieces

3 and 4, which are preferably fixed to the front axle and have a sliding connection with the rear `axle 5. As illustrated in Fig. 2, the rear axle is provided with the guides 3" and 4, in which the

members

3 and 4 slide. Said members may be fixed in any `desired relation by means of the pins 6, which pass through holes in the guides and in the

members

3 and 4 and which project on opposite sides of the axle, as shown. Movably mounted on the front wheels is a movable arm 7. In the construction shown, this movable arm isrotatably mounted upon a'sleeve 8 on the front axle 9. This arm carries at its Outer end the desired mechanism.` Asherein shown, it is provided with a platform or carrying device 10 located between the branches 11 of the arm 7 and pivoted thereto. This platform or carrying device is provided with Specification of Letters Patent.` `Patented Aug Application med Augustl 14, 1916; Serial `No. 114,932.

means for keeping it in a substantially horif zontal position during the various positions of thearm. The carrying device is connected by pins 12 with the arms 11. Connected with these pins are the pieces 13.` At the otherend of the arm` is a similar piece 14, these pieces being connected together by the cables or flexible partsland 16., The carrying device may be providedwith any desired mechanism, such as a searchlight `17. The arm7is also connected with therear set of wheels.` As illustrated in Figs. 1 and 3, there are two connecting pieceslS and 19, oneat each `side of the arm 7, the connecting pieces being pivotall'y connected to said arm at 2O and 21. connecting pieces 18 "and 19 are rotatably connected with the rear axle 5. It will thus be seen that by disconnecting the

members

3 and 4 from the rear axle andlmoving the The other ends of the Abe lifted or lowered and may be held in any desired position by inserting the pin 6 in the proper openings in the

members

3 and 4; The two sets of wheels may be moved relatively in any desired manner. In the drawings, `for purposes of` illustration, I have shown one` method of accomplishing this. In this construction, I provide a shaft 22 (sce Fig. 4) suitably mounted `in position. This shaft may be operated by means of a motor or by the handle 23 and is operatively connected by pinion 24 and gear 25 with the shaft 26. The shaft 2G is operatively connected with the

drums

27 and 28 in any desired manner, as by means of the

sprocket chains

29 and 30 which engage sprocket wheels 31 on the shaft 26 and sprocket wheels 32 connected with the drums. The

drums 27 and `2S are provided with iexible' power transmitting

devices

33 and 34 which maybe cables wound upon the drums and which extend back and `connect with the rear axle (see Fig. It will thus be seen that by rotating these drums in one direction the wheels willbe moved relatively toward each other to lift the arm, while by slacking up on these cables the weight of the arm will move the wheels relatively away' from each other and the arm -will be thereby lowered. lVhen the arm 7 is moved the

members

13 and 14 and 15 and 16 keep the platform or carrying device substantially horizontal during allthe various positions of the arm. In the construction shown in Fig. 5, the

members

3 and 4 are` S14 are alsojconnected with-these'brackets YThe ends of the connecting pieces 18 and V19 are preferably rotatably Vmounted upon a sleeve and connected with the ends of theseconneetmg pieces 1s Vthe support 37 which may be made up in any desired manner, as by angle irons, as shown, and to which is-connected a spring 38 having between its members a coil. spring 39. The end otV themovable Varm rests upon this spring and support, as shown in Figs. l and 2. I Vprefer to provide a wood bumper piece 40 (see Fig. 2) `connected with the plat- `form l() and which engages the spring as shown.' The front wheels l may be connected with the front axle 9 by means of the pivoted spindles 4l carrying the wheels and pivoted toV the axle. The device may be guided in any desired manner, as by means ofthe members 42, connected with the spindles 4l and a connecting member 43 connected with .the tongue 44, the tongue being pivoted at'45 to a-.bracket 46 on the axle. The member 43 is Yprovided with aV slot 47 yin which works a pin 48y on the tongue 44.

The device may be provided with a seat 49 connected with the arm 7. By means of this construction I am enabled to provide a light, substantial, portable device wherein thefmovable arm carrying the searchlight acts as the frame or chassis of the device, thus doing away with the heavy, cumbersome parts and at the same time securing a construction'which is easily and quickly operated and which is strong and durable.

I have described in detail a particular construction, but it is ot course evident that the parts may be varied in many particulars without departing from the spirit of myinvention, and I therefore do not limit myself to the particular construction shown Ythese wheels and transferring it to the irst or'frontrset of wheels. As the arm moves up theweight on the second pairof wheels is decreased and the weight on the front set ot' wheels increased until when the arm is in a vertical position all the weight is4 on the front set of wheels.

I claim:

l. A portable reconnoitering device comprising two Vpairs of wheels, a movable arm movably connected with one pair of wheels, a controlling connection between said arm and the other pair of wheels, and means 'tor moving said pairs of wheels toward and from each other while the said arm and controlling connection are connected therewith so as to raise and lower said arm.
