4pp1ication filed 0ciober 10, 1907. Serial No. 396,840.

To all whom it may concern:

Be it known that I, EZRA Nicholson, a citizen of the United States of America, residing at (.lcvclund, in the county of (uynhoga and State of Ohio, have invented ccrtein new and uscful Improvements in licgis' tering Devices; and I hereby declare the following to he a full, clear, and exact dcscri tion of the invention, such. as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to new and useful improvements in registering devices and particularly for indicating the distance traveled by vehicles and especially automobiles.

The object of this invention is to provide an elcctricallynctueted device of this character which will be simple and durable in construction, and accurate in its operation.

A further ob'eet of my invention is to provide a device of this character which will also serve the purposes of u s eedometer.

My invention, there ore, consists in the features of construction and combination of parts as described in the s ecilication, pointed out in the claim and il ustratcd in the ac.- companying drawings.

In the accompanying drawings Figure 1 is an outside view of the device. Fig. 2 is it View of same withdial-rclnoved and casing in section. F 3 is a section on line 33, F 2. Fig. 4 is a. section on line 4-4, Fig. 2. Fig. '5 is a detail view showing the method of mounting the contact making desamc. F ig. 7 is a section on line 7-7, Fig. 6.

Again referring to the drawings 1 reprc-,.

sents the outer casinp of the device which is preferably circular in form. At the back of the casing is arranged a late 2 on which are mounted n air of shun ards or brackets 3. In the hruc cts 3 is rotatably mounted 11 small shaft 4 and on the shaft 4 is secured a worm 5 and a ratchet wheel 0. (eutrallvin the casin and bclow the shaft l and. at a right ang e thereto is arranged a shaft 10, one end of which is journalcd in the plate 2 and the other end is journnlcd in a bracket 11 which is secured to said plum: 2. ()n the shaft 10 is 'rigidl 1 secured u gvnl wheel 12 which is arrange to mesh with the worm 5 and also a bevel gear 13. 111 proximity to the shaft 10 is nrran ed o. registering device 14 of any of the'usuafforms now on the market and commonly termed cyclometers, the

. construction and operation of which are so Fig. (i is a side view of.

well known that detail description thereof is not dccnlcdnecessary. 'lhc cloiuvivr H is so arranged that thc'shuft l5 flu-roof is at a right angle to the shaft H.) and thereon is -rigidly secured a bevel gear 16 which meshes with the bevel goal- 13 on the shaft 10.

It will he readily seen that when the shaft 41's rotated the worm 5 thereof will drive flugcnr wheel 11 on'thc shaft 10 thereby operating said shaft 11) and the bevel gear 13 thereon, which in turn drives the bevel gear 16 on the cyclonu-ter shaft, thereby actuating i the cyclomctvr. In the bottom ofthe casing i is mounted an eh'x-tro-nnignct 2i) and ahm'c the clcciro-niagnct is hinged on al'nndurv n1 phitcz'i. A coil spring, 22 is connected in fluplate 21 and to one of the brackets 3 so as in normally hold the plate out ofrontnct with the )ole of the elcctro-nmgznct. ()n the phde 21 is pivotally mounted in pawl 24 which is-nrranged to engage with the ratchctwhvcl 6 on the shaft 4. A small pin 25 extends at a right angle from the pawl 24 and u spring; .26 is mounted on. the plate 21 and engages with the said pin 25 so as to hold the pawl yieldingly against the ratchet wheel 6. When the electro-magnet 20 is energized it will attract the date 21 causing it to move down and the paw 24 is drawn over the teeth of the ratchet wheel 6 and drops down behind a. tool [1. dNhen the ina net ceases to be energized the spring 22 puffs up the late 21 cousin; the pawl 24 to move up and eing in engagement with the ratchet wheel 6 it causes a movement of the wheel and a. consequent rotation of the shaft 4. A stop 23 is provided for limiting the upward movement of the plufc 21. A flat spring 27 is arranged to press against the hub of the ratchet wheel (5 to serve as a brake and prevent the wheel moving more than one tooth at each impulse of E the pawl.

At one side of the casing are i mounted two switch blades 29 and 30, prcf- .ernbly, formed of strips of some rcsi ient 5 material, such as copper or brass. The i blades are mouned on a block of insulating material 31 so that the ends of the said blades are normally held a not. One of said blades is prefcrzibl provided with a. contact oint f 32. In proximity to [he said switch b adcs Zilnnd 30 is mounted a switch key 33 formed of some insulating material and having a cam head 34 so that when the key is turned Ibludes together and when turned in the other position it will permit the blades to in one position it will clamp the switch separate. One terminal of the electro-magoccurring in the circuit through the excessive net is connected to a binding post and the other terminal of the magnet 15 connected to the switch blade 29. The other blade 30 of the switch is connected with a binding-post 36. To the binding- posts 35 and 36 are secured flexible tongues or strips of copper 37 and 38 and to these tongues are secured the wires 39 and 40 which form the circuit of the battery 41 and the contact maker. I prefer to use these strips as I have found that where the wire is connected directly to the bindingpost the jarring or shaking of the machine reaks the wires where they are clamped to the'posts while when the wires are connected to the flexible strips this does not happen. The case 1 is provided with a dial face 42 on which are set forth characters to indicate multiples of miles and in the dial face of the cyclometer is formed an opening 43 throu h which the figures on the cyclometer may be read. The shaft 10 rojects through at the center of the dial and thereon is mounted a hand or pointer 44.

In Figs. 5, 6 and 7 wherein is shown the contact maker and the portion of the machine on which it is mounted 45 represents the hub of one of the wheels of the machine and 46 represents the steering knuckle. On the steering knuckle is mounted the contact maker which comprises two clam ing members 47 and 48 which are preferably formed of some insulatin material. The member 47 is in the form 0 a rectangular plate and is arra ed to embrace the steering knuckle and t e member 48 is made com aratively narrow and is secured to the mem er 47 by bolts 49. Switch blades 50 and 51 are secured to the member 48 on o posite sides thereof. The blades are forme (if some thin flexible material and one of the said blades is referably provided with a contact point 52. i lcxible strips of copper or other suitable material 55 and 56 are mounted-on the clam member 48 in contact with the blades 50 and 51 respectivel and to the said strips 55 and 56 are secure: the ends of the wires39 and 40. The object of the flexible strips is the same as heretofore referred to in regard to the strips 37 and 38, that is to prevent a break to come in contact with j and press it against the the blade 51, thereby completing the circuit lel to said rear side a vibration of the machine. 0n the hub of the wheel is mounted a cam 57 which is arranged the switch blade 50 contact point 52 on and energizing the electric-magnet at each rotation of the wheels of the machine.

It will be seen from the foregoing description that my device will accurately register and record the distance traveled by the machine aud it will also serve for a speedometer for by observing the movement of the hand over the dial and timing it between any fraction of a mile thereon the exact speed at which the machine is moving can be readily ascertained.

\Vhat I claim is In a device of the character described, the combination of a circular casing, an clectromagnet mounted in the lower art of said casing below the center thereo a pivoted armature above said magnet, a pawl carried by said armature, a shaft supported from the rear side of said casing and extending paralove the center of the casing, a ratchet wheel and worm wheel carried by said shaft, said ratchet wheel being ada ted to be en aged by said pawl, a second s aft supported at righleangles to the rear wall of the casing at t e center of the latter, said shaft having a bevel gear, and a worm wheel adapted to engage the worm wheel on the first named sha t, a third shaft likewise supported from the rear wall of the casing substantially parallel to the rear wall and in line with the center of'the casing, said last named shaft having a bevel gear eng ing the bevel gear on the second named shag. a registering device operated bysaid third named shaft, and means for intermittentl making and breaking the circuit of said magnet.
