lie it known that I, RALPH Siiimux, a Citizen of the United States, residing at Sunlun v, in the county oi Northninlwrland, and State of Pennsylvania, have invented eertain new and useful Improvements in Speed and Running Iiuie indicators, of 'lliPli the following a SPQClfitlltlOIl.

In my prior patents, lie-is. H.196 and No. 1,022,801. I have shown an instrument for registering the running! time of a Vehicle,- that is, the time he veLii-le is in autnal operation or motion during any given trip or period of time. as; well athe speed at any time that the machine in operation. The running time feature of the instruinont is very desirable for enabling; the owners of trnrks and il ll\'l" \'flg keep advised as to the hours of btl tfl, of each individual machine. and also as to the hours that the employ are, artoalh engzaizjrdinoperatingitheni nine.

The invention tit the pres nt aimlhfatinn embodies the running time teatnro of the prior patents referred to, together with means For registering the diatanoe traveled by the vehicle when driven in exeeqs of a given speed, and means for .'-ignalirg r the driver when his vehicle in traveling at a speed in (,Xt'tSF of Such given speed.

The invention is pai'tieularl denil'ahlo on trucks and delii'erv veliirles which are, not intended for high speeds and which are in-- jurionsly ail'eeted when driven fast.

A shaft 18 mounted in a suitahle brat) 19 upon the upper supporting plate carries a pinion 20 which meshes with the worm gear 16, and this shaft. carries a worm 21 which meshes with a spur pinion upon a shaft 23 which is arranged at right angles to the shaft 18 and is mounted in the bracket 19 and a bracket 2-1. A worm ii on the shaft 23 engages a gear 26 secured to a spindle 27 which carries the, distance. iiwlicating hand 4-. It will he evident that through the gearing just described, the hand 4 will be operated and this hand will indicate, on the scale 3, the distance traveled during any given trip.

The hand (i operated to indicate the lit?" tual runnii'ig time f the vehicle upon the scale 5 by a clock mechanism actuated by a cam wheel upon the shaft 13. 'lhis cam wheel, as shown in. the drawing. cannprises two snail cams having: cam surfaces 15 which rise graduallv from points near to and at opposite Sit N the shaft and term nate in abrupt radial faces 28". A lever l mounted upon a spindle 30, carries at it free end a roller ll which is adapted to bear against the edge of the earn wheel 25;, and this roller is constantly pressed against the cam wheel by a spring 32, so that as the cam wheel "rotates the lever 29 will rock baa-h and forth twice during each revolution of the cam wheel A link 33 extends betwu-n the lever 29 and a clutch member 3% associated with the clock train. The link pivotally connected by a screw 35 to the clutch member, and a screw 36, extending through a longitudinal slot 33% connects the link w h the lever 29. A helical spring 37 connected between screws 35 and lid constitutes the main spring for actuating the clock mechanism. The clutch iemlawr 34 COHP prises a disk, loosely mounted on a shaft 38 and provided with an extension 34*, upon the under side of which t o dogs or pawls 3t and il are rounded. These dogs are of haulened steel and their free ends a re sharp and engage the peri hery of a disk ll of softer nu-tal, such as lu'ass which mounted ronccntiwally with the clutch member 34, upon the shaft 5%.

This is accomplished by means fully described in my prior Patent No. 1,022,801, and unnecessary to describe in detail. here, these auxiliary driving devices comprising a spring pressed lever 52, mounted upon the lever 29, and carrying a spring pressed pawl 53 which engages a ratchet wheel 54, the latter being rotatable with the clutch member 41, associated with the clock train. 7

The shaft 38, which is'actuated by the clocli train, rotates once in two minutes. Upon the upper end of this shaft is mounted a worm gear 55 which engaged by a spur gear 56 upon a shaft 57, mounted in the bracket '2' and upon this shaft is arranged a. worm which engages agear 59 upon a shaft (50 which leads to and operates the register 7 for reg stering the total running time of the vehicle. Another worm 61 is mounted upon. the shaft 57 and this worm engages a gear 62 upon a shaft or spindle (53, to which the indicating hand 6 is attached, and this hand indicates upon the scale 5 the runing'time of the vehicle for any given trip, or the trip-hours.

Upon the spindles'Q'T and 63 are mounted heart-shaped cams FA and 65 and a reset ting slide (:6 is suitably formed and arranged to actuate these cams and thereby turn the indicator hands 4 and (3 to zero on the scales, when the slide is operated. It is unnecessary to describe in detail the construction and operation of thisslide as equivalent means for re-settiug indicator hands is well known in the art.

The main feature of the present invention is the means For indicatin and registering distance llI-l'x'Qlk'll at speeds in excess of a given speed which will now be described.

llpou the upper supporting plate 14 of the instrunu-nt are arranged guides (37 and on, having slots to receive a slide (39, th slot in the guide (38 being considerably wider than the slid-J to permit latcral movement of the slide. The slide is provided with a. Stop '70 adapted to abut against the. guide (37, and the lo is normally held with the stop against saulguide by a spring 71 attached to the guide and to an arm 72, cured to the slide. This spring is at an any to the enter line of the Slide and therefore tends to hold the end portion m of the slide against the end portion 68" of the guide (38. he end portion (19" ot' the slide, which may be termed the. forward end portion, projects over the worm wheel 16 and into the path of movement oi two top 0f the guide 68.

pets 73 which are arranged at diametrically opposite points on said wheel. The center line of the slide is radial to the axis of the wheel 16 and the end of the slide which is adapted to be engaged by the tappets is beveled in opposite directions from the center, as shown at (39, to provide cam-sub faces so that each time a tappet passes the end of the slide, the latter will be moved rearwardly by the tappet and it will then be drawn forwardly by the spring 71 to its normal position. Each time the vehicle moves a given distance, say one-sixtieth of a mile, this backward and forward move ment of the slide takes place. The slide has, on its under side, a roller 74 which normally rests against one side of a pawl 75, pivoted to the plate 14, and the free end of this pawl projects into the path of movement or" a shoulder 76 upon a disk 76, which latter is secured to the clutch member 3 of the time mechanism by a sleeve 76 surrounding the shaft 38. Hence, when the ve-.

hicle is in motion, the disk 76 and its shoulder 76 will rotate in the direction of the arrow with the clutch member 34, and with the time mechanism, while the main spring is pulling the said mechanism and this disk, and this shoulder will be rc-set in an initial position each time the clutch member 34 is reset in its initial position at the completion of eachunit of distancev traveled by the vehicle. l/Vhen the shoulder 76 is moved to its initial. position, it'moves the 'pawl or movable guide 75, which, in turn, bearing against the roller 74 on the Slide, moves the slide away from the end 68 V Thi'slateral movement of the slide by the time controlled shoulder 76 occurs about the time the slide has reaclied its rearward limit of movement. The slide carries a dog, 77 pivoted to the slide at 78 and adapted to engage one arm 79 of a bell crank lever 79 when the slide is held a sullicient distance away from the end (38 of the slot in the guide-68, during the backward travel of the slide. The arm 79 of the bell crank lever is connected by a link 80 to a crank arm 81 connected to the register 9. A suitable spring 82 holds the arm 79" of the bell crank-lever normally in pdsition to he engaged by the dog 77 when the slide is held a sufficient distanceqaway 31 travels down the radial surface 28 of one of the cams on the cam wheel 28, and lhe clutch member 34 and disk 7G.are-re-set in their initial positicfi'is, the shoulder 76f on the disk moving the rear end. of the slide laterall so as to car'ry the spring pawl or dog 77 out beyond the projecting arm 79 of the bell crank lever. The slide then moves forward, the pawl 77 slipping past the arm 79 and at the commencement of this forward movement, the time controlled shoulder 76* commences to move with the time mechanism and to allow slide 9 to swing toward the end (58 of the slot 68. If the movement of the vehicle is in excess of a given speed for which the partsare set, say twenty miles an hour, the slide will move forward and will he pushed rearward again by one of the tappets before the shoulder 76 has been carried far enough around by the time mechanism to allow the pawl 77 on the guide 69 to move out ol the path of the arm 79 on the bell crank lever, and hence, the pawl will engage said'arm during the rearward movement of the slide, causing the. arm to rock and operate the register 9. If, however, the vehicle is moving at a rate lower than the predetermined limit of twenty miles, the shoulder 76" will move far enough from its initial position during the forward and back movement of the slide to allow the latter to carry the pawl 77 out of line with the arm 75%, and hence the pawl will pass the arm without causing an operation of the register 9. From this it will be evident that whenever the. vehicle exceeds a predetermined speed, the register 5) will operate to record the distance traveled at its excess speed, and so lon as the vehicle travels at less than this prer etermined speed, the register 9 will not be operated.

In order that the pawl 75, which is used simply as a guide for the roller 74 on the under side of the slide, may not press on the shoulder 7l'i af tier tlie latter has started to move with the time mechanism, the guide 75 may be connected by a pin and slotted link 86 to an arm 29 on the lever 29. As this lever rocks when the time mechanism is re-set and then is slowly moved by the cam wheel 28, the link may be used to support the guide 75 during a part of the movement of the slide after the time mechanism has moved a certain distance from its initial position.

In the figures above described, only one excess-speed register is shown; but I may employ several to register distance traveled at different excess speeds as illustrated in Figs. 5 to 7, inclusive. In Fig. 5, the mechanism is substantially the same as in Fig. 2, except that the pawl 77 in Fig. 2 is arranged to engage a. single hell crank, while in Fig. 5 the pawl 77 which is mounted upon and travels with the slide (30, has a forked end adapted to engage bell cranks for operating two registers, 9 and 9 The forked ends 77 and 77 of the pawl, at low speeds, travel in paths at one side of the arm 79" of the bell crank 79 and straddle a projection 9O on an arm 90 of a bell crank 90. The bell crank 79 operates :the register 9 and the bell crank 90, through a, link 91 operates the register 9. Another bell crank 92 is mounted upon a stud 93 which supports all of the bell cranks and the bell crank9'2 has one arm 92, somewhat longer than the arm 79 of the hell crank 79 and shorter than the arm 90 of the bell crank 90. This bell crank '92 has an arm 92 to which is attached a pin 9i, fitting into a slotted arm 95 of a signal plate 95 which is pivoted upon a suitable post 96. This signal is hidden by the casing when in the position shown in Fig. 5, but when the bell crank 92 is rocked, one part marked 15 in the drawing will show through an opening 97 in the casing. and when the bell crank is rocked furtliier, another part of the signalplate, marked 20 will show through said opening.

It has previously .beenexplained in con nection with Figs. 14, and Figs. 8!), inclusive, that the longitudinal movement of the slide 69 is controlled by the speed of the vehicle, while its lateral swinging movement, toward the axis of the disk '76, is controlled by the time mechanism. To repeat, briefly, the spring 71 constantly tends to move the slide forward, or longitudinally, toward the axis of the gear 16, on which the tappets 73 are mounted, and also to swing the slide laterally toward the axis of the disk 7 6, its rear end having room to play in a slot in the guide. 68, as shown in F ig. 8?, and being normally pulled by its spring toward the side 68 of said slot. \Vhen the slide, moved by one of the tap' pets 73, is in. its reairmost position, the clutch member 34, and the disk 76, which is secured to said memher, are turned backward on the time mechanism by the operation of the cam disk 28, and in this resetting movement,

which occurs at fixed distances of travel bf the machine, the shoulder 76 of the disk 76, swings the slide away from the axis of said disk. The slide is then moved forward by its spring and again moved rearward by a succeeding tappet, and during this forward and backward movement the slide slowly swings laterally toward the axis of 1 0 varies according to the speed of the vehicle,

it is evident that if the speed is great? the pawl 7 7 which is mounted on the slide, will move rearwardly'therewith in a path farther from the axis of. the disk 76 than if the speed is slow, and that it will follow intermediate paths at intermediate speeds. To set up on the register 9 the distance traveled at speeds of fifteen miles and not over twenty miles per hour, and on the register 9 the distance traveled at speeds of twenty or more miles per hour, without registering speeds under fifteen miles perhour, the arms 00 and of the bell cranks which operate the registers will be of such lengths and so related to the paths of movement of the pawl 77 'on the slide 6 that when the \e hicle is moving at a. speed below fifteen miles per hour, the pawl will not engage either bell crank, and neither register will be operated. When moving at fifteen miles, the pawl will engage in its rearward movement the bell crank 90 but not the hell crank 70. and when the vehicle is moving at twenty miles or over, the pawl will engage, in its rearward movement, the bell crank 7 but not the bell crank 00. \Vhen the vehicle is moving at any speed below fifteen miles per hour, the pawl will not engage the arm 92, and when moving at fifteen miles or over, the pawl will engage the latter arm and cause the' movement of the signal 95.

In Fig. 6, the forks 77" and 77 of the pawl are shown in the position which they occupy relatively to the bell cranks at a speed below fifteen miles per hour. At these low speeds, it will be noted that the forks of the pawl straddle the downward projection 90 on the arm 90, and both of said forks are at the left of the bell crank and 92 and therefore none of the bell cranks will be operated in this position of: the pawl. At fifteen miles per hour, and less than twenty miles, the forks of the awl will travel in a path to the right of that indicated in Fig. 6, so that the fork 77" will engage the downward projection 9O on the arm 90 and operate the register 9. The fork 77 will, at the same time, engage the end of the arm 92 and this will cause the signal 95 tohe swung up so as to expose the numeral 15 thereon through the opening 97. At thisspeed, however, the fork 77" will pass the end of the arm 7 9 and the register 9 will not be operated. Upon increase in speed to twenty miles or more per hour, the fork will travel in a path farther to the right in Fig. 0, andthe arm 77 will then engage the bell crank 79 and operate the register 9, and it will also engage the arm 92 and move the signal 95 to expose the numeral 20 through the opening 97; but in this last assumed position of the pawl, the fork 77 thereof will travel in a path at the fight of the projection 90 on the arm 90, and the latter will therefore not he moved, and hence, the register 9? will not be operated. 'The signal, when operated, serves the purpose of calling the drivers attention to the fact that he is runningat a speed above his limit.

In order to keep the signal plate in front of the opening 79 as long as the speed is excessive, a locking pawl 100 is pivoted upon a stud 101 on the supporting plate 1%, and this pawl is spring pressed toward a seg ment 102. which is connected to the signal plate and is provided with notches 103 and nu for engagement with the locking pawl. A tripping rod 105, connected to an arm of this pawl, extends through an opening in the guide piece (37, into the path of the tappets 73 on the wheel 10. If the signal plate has been thrown up to expose the numeral 15 through the opening 97, the pawl 100 engages the notch 103 and the signal plate is therebly held with the numeral 15 exposed through the opening. If the speed continues at fifteen miles an hour, the engagement of one of the tappets 73 with the reeds twenty miles per hour, the bell cranks 79 and 92 will be simultaneously operated, as before explained, and the signal-plate will be thrown up to expose the number 20 through the opening 97 by the opera- .tion of the bell crank 92, and the pawl 100 will engage the notch 104, in. the disk 102, and lock the signal plate in position-With the numeral 20 exposed through the opening 07. This will not be pchanged as long as the speed equals'or exceeds twenty miles per hour, as at such speeds the bell crank 92 will always be engaged by the forked arm 77 at the moment when the tripping arm 105 is operated, and when this arm is released, the pawl 100 will still be in engagement with the notch 104. If the speed now falls below twenty miles and not below fifteen, the arm 77 of the pawl 77 will engage the low part of the bell crank 92, and when the tripping arm or rod 105 is operated the pawl 100 will be released from the notch 104, and the signal plate will drop and said pawl will engage the notch 103 and hold theslide with the numeral 15 exposed through the opening 97. But if the speed drops below fifteen miles per hour, the forked pawl will not engage any of the' bell cranks and at the next operation of the tripping rod 105, the pawl100 will be re leased from the notches in the disk 102 and the signal plate will drop below the opening 97. L

.- In Figs. 10 and 11, I have shown a centrifugally operated indicator for indicating and registering distance traveled at excess speeds. In these views the shaft 105 is driven by a speed proportional to the speed of the vehicle and carries a centrifugal governor 106 which operates to pull downward a sleeve 107 on the shaft 105, against the action of a. spring 108, as the speed increases. A gear 109 upon this sleeve is adapted to engage a gear 110 upon a register 111 when the speed equals a given limit, as say fifteen miles per hour. These gears Will remain in mesh as long as the speed of the vehicle continues at fifteen miles per hour, or any speed above fifteen and less than twenty miles per hour. Should the Vehicle speed equal or exceed twenty miles per hour, another gear 112 on the sleeve 107 will be brought into mesh with a gear 113 upon a register 114, and the latter will register the distance traveled at a speed of twenty miles per hour or at any greater speed. The teeth on the. gear 113 are long enough to permit the gear 112, after its first engagement, to remain in mesh therewith, while the latter gear is carried to its downward limit of movement by the operation of the governor, so that for all speeds above twenty miles per hoiir, the gear 112 will drive the gear 113 and operate the register 114. It will be evident that as the speed drops below twenty miles per hour, the sleeve will move upward, carrying the gear 112 out of engagement with the gear 113, and carrying the gear 109 into engagement with the gear 110, and the register 111 will be operated by the

gears

109 and 110 until the speed drops below fifteen miles per hour, when the gear 109 will pass out of engage ment with the gear 110, and below a speed of fifteen miles per hour, neither of the registers will be operated. A signal plate or arm 115 is pivoted to the casing at 116 and has an arm 115 which extends between collars 117 on the sleeve 107, the arrangement being such that when the vehicle is operating at speeds varying from fifteen to twenty miles per hour, the signal arm will i be rocked into position to expose the numeral 15 thereon through the opening 118 in the front wall 119 of the casing, and if the speed equals or exceeds twenty miles per hour, the numeral 20 will be exposed through said opening. If the speed is be low fifteen miles per hour, the signal arm will remain below the opening in the casing. A distance register or odometer 120 is sh own in the lower part of the casing, ano it is connected by

gears

121 and 122 to the shaft 105, this register being continually operatcd while the vehicle is in motion to register the total distance traveled.

What I claim is:

1. A mechanisn for indicating the dis tance traveled by a vehicle in excess of a given speed, comprising a member operating at a speed proportional to the speed of the vehicle, a register, and means controlled by said member for actuating the register only when the machine exceeds the given speed, to register distance traveled by the vehicle in excess of said given speed.

2. A mechanism for indicating the distance traveled by a machine in excess of a given speed comprising a member operating at a speed proportional to the speed of the machine, a time mechanism operated by said member, a register, means associated with the register for actuating the same, and a dcvice, movable by said member and controlled in its position by said time mechanism, adapted to operatively engage said means when the speed of the machine exceeds a given speed.
