B'W'llTOH-STAND AND SIGNALING DEVICE THEREFOR.-

To alllwhom it concern:

a lie itknown that I, HARRY C. ODENKI'RK, a citizen of a, the United States, residing at Cleveland the county of Cuyahoga and State of hio, have invented a certain new and useful lmlp'ovemen't in Switch-Stands and Signaling vices Therefor, of which the following is a full, clear, and exact description,referenc'e This invention relates to signal devices for use in connection with railway switch stands, particularly such, stands as are shown in my atents Nos. 628,281 and 628,282, granted to me July 4th, 1899. Y

.In said switch stands I employ an oscillatog cam formovingback'and orth the switch points, said eambelng mounted in the switch stand soastolie ina horizontal direction. To 20. the axisor shaft of this cam I attach means for operating the-switch signals or targets, and my present invention relates'particularly to themeane which I employ for operatin these signals.

n the drawings forming part of this application, Figure 1 is a perspective view a showing a form of switc stand which is illustrated in the said switch stand aving'my invention connected thereto. Fig. 2 is 'a detail view, partly in section and partly in elevation, of a cam'rnemberand its connections for oscillating thesignals. Fig. 3 is a detached secvie,w of the lower end of the stem upon 31' which the signals are mounted, and Fig. 4 1s a ectional view taken through Fig. 2 on the As is well understood in the art, these signals are intended to indicate the condition of the railway track as to the location of .trains in the vicinity of said switches. When the signal is turned so as to show one form of indlication, it is understood that the track is e ear, angles to its former position, this signal will display a danger sign. Inasmuch as these signals are sub ect to all kinds of weather, it is necessary that they be protected to the fullest possible extent against the elements, and that they operation. Taking casingjoi a switch stand, which may be of any I approved I shown, is of the type set forth and described Specification of Letters Patent. Application filed October 15. 1908- Berial No. 338.929-

being had to the accompanying patents above. referred to,

be positive and certain in their u the drawings for a more 'de'-. taileddescnption, 1 represents the outside Patented J an. 14,, 1908.

in my store-mentioned patents. I S2 switch stand is secured to the ties 2 of ti. railway track, not shown.

3 is the operating lever for turning the cam within the switchstand, said lever bein' secured to one end oifthe shaft upon which .said cam is mounted, the shaft at its oppo site end being provided with a disk or crank 4 outside the casing l.

a 5 is the o crating bar or connecting rod which joins t e mechanism within the casing 1 to the switch points of the'railvifa track, the construction being such that as t ejlever 3 is oscillated through180fthe-said rod 5 will 'be moved back and the-switch.

Mounted signal post 6, which may be 'of any desired length, dependent upon the location of the switch stand. This post, which is preferably of tubular metal, as is .shown' in Fig. 2 of the drawing, is provided above the switch stand brace rods .8 for strengthening the "signal post is a cam sleeve 14, said sleevehaiving an arm 15, to which is secured the uppere'nd of a connecting rod downwardly and being connected to the crank or disk 4 on the switch stand shaft.

whereas if thesignal is turned at right raised and lowered, which operation will also raise and lower the sleeve 14 about the staff 11. This sleeve is provided on one side with a spiral earner slot 17, into which slot. projects a pin or stud 18 that is secured to the stafl 11. .Therod 16'is guided in its vertical movement b the collars 7 and 19 on the signal post set at the said sleeve '14 will be 'prevented from rotatingby said rod. It wi be seen therefore thatw en the collar l4islifted,

is connectedthe signal blades and IO-as forth to open or close upon the switch standrasing is a with a collar 7, to which may be attached.

y the cam slot 17 will e age with the pin-'18 construction but which, as. and will thus oscillate t 'e staff 11, to which end of the signal post 6, as shown in Fig. 2.,

post, as shown in Fig. 4. Loosely surroun mg the staff 11 just above theiupper end of the signal 16, said rod extending As said shaft is oscillated, the rod 16 will be 5., I U v staff and orpreventingisald'sleevefrom rothe cam slot to engage 2 ferring the cam slot 17 to the stafi 11 and the well as the signal lantern 20. The itch of the cam slot is such that as the col 'ar 14 is moved from one extreme ositionto the other the staff will be rocked't on b 90. T In or der to cover the sleevel4, t e cam slot; 17

and the'pin 18, I employ a casing 21 which, at its upper end, snugly fits the staff 11 and extends over and about the sleeve 14, said casing moving up and down with said sleeve. By'this'means, the operating parts for the siglirials are protected from the weather. rom the above construction, it will be seen that I have provided a signal operating mechanismthat is simple and l ght in its construction; that has no parts that are liable to in its 0 eration, and that isthoroughly protected mm the elements.

An obvious modification of the above-del scribed construction would consist in transpin or lug 18 to the sleeve 1-4. Other details I m the construction shown may be changedwithout departin from the spirit of myinvention, and the ollowing claims are not intended to be limited any further than theprior ar necessitates.

Having thus described invention, I

1. In a railway signaling device, a stafi upon which the signal is mounted, a sleeve surrounding said staiflsaidsleeve being pro-* vided with a cam'slot, a pin or lug projecting -fr om' said stafiinto said cam slot, and means for movin said sleeve longitudinally of said "tating, said movement ioff'the sleeve causin theic'ahislot to on age the saidpin or'lug an "thus turn the sta to operate the slglliil.
