ABRAM ALBERT WEAVER AND JOHN VILLIAM BROOKS, OF VARRENS- BURG, MISSOUR.

STATION CALL AND SIGNAL.

' SPECIFICATION forming part of Letters Patent No. 449,505, dated March s1, 1891.

Application filed November 8, 1890- Serial No. 370,788. (No model.)

To all whom, it' may concern;

Be it known that we, ABRAM ALBERT W EAVER and JOHN WILLIAM BROOKS, citizens of the United States, residing at Warrensburg, in the county of Johnson and State of Missouri, have invented certain new and useful Improvements in Station Calls and Signals, and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to station-indicators, andhas for its object to simplify the operating 'mechanism for operating the name-strip and at the same time releasing the alarm mechanism, whereby attention is called to the device.

The improvement consists of the novel features and the peculiar construction and combination of the parts which will be hereinafter more fully described and claimed, and which are shown in the annexed drawings, in which- Figure l is afrontview of anindicator embod ying my invention. Fig. 2 is a cross-section of the name-strip, the spools on which the said strip is Wound, the shafts for the spools, and the guide-rollers about on the line 2 2 of Fig. 1,looking to the left. Fig. 3' is a cross-section on the line 3 3 of Fig. l in front of the operating-disk-returning spring, looking to the left, showing the trip-bar, the brake mechanism, the operating-disk, and the returning-spring. Fig. 4 is a cross-section on the line 4 4 of Fig. l just inside ot' the operating-disk, showing the ratchet-Wheel on the windingshaft, the paWl for operating the same, and the brake mechanism. Fig. 5 is a cross-section on the said line 4 4 just inside of the operating-disk, looking to the right. Fig. 6 is a perspective view showing the case opened. Fig. 7 is a detail perspective view showing the means for locking the spools on their shafts. Fig. 8 is a detail perspective view of the scape-Wheel, thepallet, and the releasing mechanism. Fig. 9 is a bottom plan view showing the relation of the releas? ing mechanism to the pallet and the scapewheel. Fig. lO is a detail perspective View of the arm for engaging the pallet and bearing on the scape-wheel. Fig. 11 is a front View of the movement, showing the relative arrangement of the releasing mechanism and the operation of the same by dotted lines.

The case is of suitable construction to contain the operating parts of the indicator and is composed of the back A, bottom B, ends C and D, top E, and `front or door F, the latter having an opening through which the namestrip is seen, the said opening being protected by glass. The guide-rollers H and H' and the shafts G and G are journaled at their ends in the end pieces D and O and between their ends in the partition I, which is parallel with and but a short distance from the end C. The spools g and g', on which the naine-strip J is wound, are mounted on the shafts G and G', respectively, and have notches g2 in their ends, which receive a cross-pin g3 in each of the shafts, by means of which the spools are made fast to and caused to revolve with the said shafts. Each of the shafts is provided With a brake-Wheel, the brake-wheel K being on the shaft G and the brake-wheel K on the shaft G.

TheV brake-shoes 7i; and k operate on the brake-Wheels K and K respectively, and are caused to press thereon by means of the connectingspring .762. The ratchet-Wheel k3 is formed on the side of the brake-Wheel K and is operated on by the pawl 7a4, which is pivoted on the disk L, that is mounted loosely on the shaft G, so as to turn freely thereon. The returning-spring Z is secured at one end to a post and at its other end to the disk L and serves to return the said disk to a normal or starting point. The operating-cord M is connected with the disk L.

The alarm N comprises agong-bell and the usual train of gearing for operating the hammer.

O represents the scape-wheel of the movement, and P the,pallet of well-known construction and operation. The releasing-rod Q has an endwise movement and is provided with an arm q, which projects at right angles therefrom, and which is recessed in its side to embrace the pallet and prevent its operation.

This arm q also bears on the scape-Wheel and acts in the capacity of abrake-shoe. The spring q acts on the rod Q and holds the arm q in engagement with the pallet and with the TOO scape-wheel. The alarm is secured on the door F, and the rod Q projects through the door and comes in contact with the bar R, which latter is acted on by the projection S on the disk L when the latter is operated.

The operation of the invention is as follows: A pull on the cord M rotates the disk L, and by means 0f the pawl 164 and the ratchetwheel 7c3 rotates the shaft G and winds the name-strip thereon. projection S on the disk L strikes the bar R and pushes the bar Q in in such a manner as to disengage the arm q thereof from the pallet and the scape-wheel to permit the sounding` of the alarm.4 On releasing the cord the spring Z will carry the disk back to its vnormal posi;

tion, and the spring q will press the arm q in engagement with the scape-wheel and the pallet. When the name-strip is wound from the roller g onto the roller g and the car or4 vehicle is in position for the return trip, the end D, door F, and top E are opened about]l as show'n in Fig. 7, and the spools q and g are removed from the shafts G and G and replaced thereon in reverse order-that is, the

spool g, which was on the shaftG, is now placed proportionally simplied.

Having thus described our invention, what we claim,and desire to secure by Letters Patent, is-

1. In a station-indicator, the combination, with the name-strip and the name-strip-oper- At the same time the' ating mechanism, of an alarm and a releasing device to be operated on by the name-stripoperating mechanism and provided with an arm which operates on the escapement ofthe alarm-movement, substantially as described.

2. In a station-indicator, the combination, with the name-strip and name-strip-operating mechanism, of the alarm, the rod Q, having an arm to engage with the escapement of the alarm-movement, and the bar R, in contact with the rod Q and adapted to be operated on by the name-strip-operating mechanism, substantially as described, for the ypu rpose specified.

3. In a station-indicator, the combination, with the shafts and means for operating one of the shafts, of a naine-strip having the names printed on both sides thereof and rollers having the ends of the name-strip connected therewith and adapted to be slipped on or off the said shafts and adapted to be fastened to the said shafts, so as to revolve therewith, substantially as set forth.

4. In a station-indicator, the combination of the shafts G and G', mechanism for operating shaft G, the removable spool adapted to be held on the said shafts to turn therewith, the namestrip printed on both sides, the brake-wheels on the shafts, and the brakesho'es connected and caused to press upon the brake-wheels by a spring, substantially as set forth.

In test'imonywhereof we affix our signatures in presence of two witnesses.
