JAMES C. RIOKETSON, OF MILWVAUKEE, IVISCONSIN.
ELECTRIC INDICATOR FOR ENGlNE-SHAFTS.
SPECIFICATION forming part of Letters Patent No. 404,867, dated June 11, 1889.
Application filed January 26, 1889. Serial N0.297,609. (N0 model.)
To all whom, it may concern:
Be it known that I, JAMEs O. RIOKETSON, of Milwaukee, in the county of Milwaukee, and in the State of \Visconsimhave invented certain new and useful Improvements in Electric Signals for Engine-Shafts; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to electric signals for engine-shafts, and will be fully described l1 ereinafter.
In the drawings, Figure 1 is an elevation, partly in section, of one form of my present invention. Fig. 2 is a like view of another form of the same. Fig. 3 is an end view of the shaft and attachments shown in Fig. 2. Fig. 4 is a detail view illustrating one manner of securing the cam to its band or strap on the line 4 4 of Fig. 3.
My present invention has special reference to devices for indicating at any point distant from the shaft of a marine engine the direction in which said shaft is revolving, as well as its rate of speed, and is in part an improvement on the devices set forth in my prior application for patent, filed August 31,1885, Serial No. 17 5,7 14, but is applicable to any reversible shaftin v A represents the shaft of a marine engine, which has secured to it a cam B, whose opposite side edges are alternativelyoperative, depending upon which direction the shaft is revolvin This cam is preferably secured to the shaft by a band or strap 0, having suitable fianges or lugs c, bolted to the cam B, or to flanges or lugs I) 011 said cam, or to an angle-plate a,interposed between the said flanges b and c, as best shown in Fi 4., the particular method of attaching my cam 13 to the shaft A being non essential so long as it is firmly secured thereto so as to revolve with it. The said cam B may be a double cam, as shown in Fig. 1, or a single bent strip, as shown in Fig. 2, so long as the outside or opposite side edges are shaped to be alternatively operative, as hereinafter described.
D represents the rear bar of a suitable supporting-frame, having cross-str1ps (Z (P, on which the casing E of the slide F rests, said casing E being hinged to said ci'ossstrips, as shown at (Z d, and provided with. a longitudinal slot 6 in its bottom plate for the admission and travel of the lower part of the pin f, depending from the slide F, and which pin is surrounded by an anti-friction sleeve G (held in place by screw g) for engagement with the side edges of the described cam B. This pin f, in the form of my device shown in Fig. 1, extends entirely through the slide F and projects upward therefrom, (forming a contact-pin f,) terminating at its upper end in a bifurcation, between the arms of which an anti-friction roller II is j ournaled on a shaft h. From the ends of said slide F there project guide -pins I I, extending through perforations in the ends'of the slide-casing E, between which ends and the ends of the said slide the said pins are surrounded by spiral springs In Fig. 1 the said pins I I are shown as guide-pins only, while in Fi 2 these pins serve as contact-pins as well, and hence in the form of device shown in said Fig. 2 I dispense with the upward extension f of the pin f, which serves as a contact-pin in the form shown in said Fig. 1, in the manner hereinafter described.
0, Fig. 1, represents a timber or frame-work supported above the slide-casing E and carrying push-buttons J J, having projecting push-rods j, respectively, and electrically connected to the distant signals Pand I and battery L by the wires 1), q, r, s, andt and the wires 1), q, r, s, and t respectively, as shown in the diagram portions of my drawings. From the timber 0 there depends a hanger N, to which is pivoted by journal at a double U-shaped lever K, one of whose outer free ends 76 is normally held (as by spring m, se-
cured to rod M or other part of the framework) just beneath but out of contact with push-rod j, while the other outer free end 7; of said lever K is likewise normally held (as by spring m, secured to rod M or other part of the framework) similarly just below but out of contact with puslnrod j. Hence it is obvious in this form of my device thatarevolution of the shaft A in one direction (forinstance, in the direction of the arrow shown on said shaft A in said Fig. 1) will cause one side of the cam 13 to' impinge against the slecvc-covercd end G of pin f and move said pin and its slide F to one side, so that the upper part f of this pin,with its roller II,would strike against the lever K, and (in this described revolution) thereby raising the end k of said lever against the push-rod 7" of push-button J, thereby closing the circuit 1) P g r L s t and actuating the distant signal P in such circuit, (the guide-pins I I insuring that the slide F will move truly, so that the said roller II will strike against and raise the said arm of the lever K, as described,) and similarly if the shaft A revolves in the opposite direction, then the other side of the cam 1-3 will impinge against and move the pin and its slide and roller II, and this will raise the other free end 7c of lever K against the push-rod j of push-button .I and close the other circuit 1) P (1 9' L s t, and thereby actuate the distant signal P in such other circuit. Thus the captain in the pilothouse (or wherever the said distant signals may be located) will at once know in which direction the shaft is revolving, (as well as its rate of speed by reason of the interval between the ringing of the bells or movement of the signals, whatever they may be, using bells by preference) the bells, if such are employed as the signals P and P, being preferably of different sound, for obvious reasons.
Inasmuch as it is only at certain times (as when entering or leaving port or making landings) that my device is needed, I have shown at d (I my slide-casing E hinged to its supporting-frame D d d? and provided with a rod Q, to which may be attached a cord, spring, or wire It, for raising said slidc-casing and dependent pin f out of the path of motion of the cam B, and I may, if desired, attach to this casing the spring-andcord arrai'lgcment shown and claimed in connection with the slide-casing set forth in my application for patent for an analogous device filed October et, 1888, Serial N 287,162.
In the foregoing description relative to the .form of my device illustrated in. Fig. 1 I have set forth the means in whichI make indirect communication between a contact-pin on my slide and the push-rods electrically connected to the distant signals-mamely, by the interposition of a leverand in Fig. 2 I have shown a means of direct communication, as follows: In this latter form of my device I dispense, as stated, with the lever If and contact-pin f" II, and secure the pushbnttons J J to vertical supports 0 o, rising from cross-beams I) I) of the supportingframc, so that the pnsh-rodsjy" of said pushbuttons shall be directly in the path of motion of the guide-pins I I of the slide F, so that when the shaft revolves in either direc tion and the cam I; impinges against and moves to one side the lower part G of the pin j" the slide F will be moved therewith, and the guide-pin I or I will thereby come in direct contact with the push-rod or 7", and thereby close the circuit on. that side and actuate the signal in said circuit in the man ner already described.
In order that the engineer may be certain that the shaft when stopped is in such a position that the signals will not be actuated thereby, I may employ an indicator like the lug or rod '1, secured to the shaft in any suitable manner, as by theband or strap U, which indicator is located at a point on the shaft on a horizontal line midway between the horizontal lines of the ends of the cam I as best shown in. Fig. 3, and then when this indicator 'l is in a vertical upward position it evidence that the cam 13 is free from contact with the pin f. The said indicator may be attached in any manner to the band U and the ends of the latter flanged, as shown at a, and riveted together, thereby holdin the strap firmly to the shaft.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In an electric signal for OIIglllQ-SlllftS, the combination of a revolving shaft and. a two-sided or double cam attached thereto, with a pair of push-buttons electrically connected to distant signals, and. a pin adapted to be moved by said cam to actuate said pushbuttons, substantially as set forth.
2. In an electric signal for engine-shafts, the combination of a revolving shaft, a twosided or double cam attached thereto, and a movable pin depending in the path of motion of said cam, with a pair of push-buttons electrically connected to distant signals and adapted to be actuated by said pin, substantially as set forth.
3. In an electric signal for engine-shafts, the combination of a revolving shaft, a twosided or double cam attached thereto, a movable pin depending in the path of motion of said cam, and a slide connected to said pin, with a pair of push-buttons electrically connected to distant signals and adapted to be actuated by said. pin, substantially as set forth.
-l. In an electric signal for engine-shafts, the combination of a revolving shaft, a twosided or double cam attached thereto, a movable pin depending in the path of motion. of said cam, a slide connected to said pin, a coin tact pin or pins carried by said slide, and a pair of push-buttons electrically connected to distant signals and adapted to be actuated by said contact pin or pins, substantially as set l forth.
5. The combination, witharevolving shaft, of a two-sided or double cam attached thereto, a pair of distant signals,push-lnlttonslocated. adjacent to said shaft and connected by electric circuits to said distant signals, a horizontally-moving slide carrying a pin depend ing in the path of motion of said cam, and means, substantially as described, for closing one or the other of said. electric circuits and actuating the signal in said circuit thereby closed, substantiall y as set forth.
6. In an electric signal for engine-shafts, the cmnbination of a revolving shaft with a ITO cam partially encircling the same, and an inthe county of Milwaukee and State of Visdioator secured to said shaft at a point on a consin, in the presence of two witnesses. horizontal line between the horizontal lines T of the ends of said cam, substantially as set JAMES RICKETSCm' 5 forth. Witnesses:
