vApplication filed April 25, 1913. Serial No. 763,497.

To all 'whom it may concern.:

lBe it known that we., CHARLES Vf. Dann and CRAWFORD P. MoGINNrs, citizens out the United States, residing at Chicago, 1n the 5 county of Cook and State of Illinois, have invented a certain new and useful Improve ment in Recorders, of which the following is a speciication.

Our invention relates to improvements 1n indicators and has for one object to indicate violent changes in the velocity of'moving vehicles or other-moving parts. It 1s so arranged that it is in operation and indications are made only when suiiiciently violent changes are to be recorded. rlhus the life of the .blank record sheet or member is ektremely long, since instead oit moving in response to any xed driving means it operates only when it is necessary for 1t to operate to get a record and the device thus needs a minimum of attention.

It is illustrated diagrammatically in one form' in the accompanying drawings, where- 1X1- Figure l is a side elevationin part section with parts broken away; Fig. 2 1s -a plan view in part section withparts broken away; llig. 3 is a front elevation in part section vwith parts broken away; Fig. t is a side K elevation with parts broken away somewhat along the line lL-e of Fig. 2; Fig 5 is a plan View of one of the recording pendulums with parts in section; Fig. 6 is a section along line 6 6 of Figr 3; and Fig. 7 is a plan view of the record-sheet. 4

Like parts are indicated by the same letter in all of the figures.

A isv a base upon which is mounted a cover Aheld in position |"by the lugs A2 and i0l the lock A5 and provided with a transparent window A4. I

-B is a bracket mounted on the hase A supw porting the record drum B1 rotatably mounted thereon.

B2 is a tooth ratchet wheel keyed to the drum.'

B3 is an arm pivotally mounted on the bracket B provided with the toothBl in engagement with the toothratchet wheel B1 and held against the ratchet wheel by the spring B5.

C is a bracket.

@l is a ,roller rotatably mounted thereon. C2 is a record sheet wound about the roller and extending over and wound about the drum B1.

C3 is a shaft upon which the roll-erw@l is mounted. v

C4 is a spring disposed between the hub of the sleeve C5 on the bracket C and the portion of the roller to yieldingly resist its rotation. Y

CG is a feed pendulum free to swing upon a horizontal axis and supported on the bracket C.

C7 is a feed arm pivotally mounted on the pendulum lever arm and provided with a tooth C8 in opposition to the teeth on the tooth ratchet wheel 132.

C is a spring holding said tooth C8 in engagement with said wheel.

l) is a bracket mounted on the base A.

D1, U2 are horizontally disposed lugs proj ecting outwardly trom said bracket.

1 D3 is a sleeve pivotally mounted upon said ugs.

D4 is a dat spring seat onsaid sleeve.

D5 is a spring on said lugs in opposition to said sleeve D8.

D 'is a pendulum lever rigidly mounted on said sleeve D3 perpendicular thereto and located in a horizontal plane andv free to swing in said plane as the sleeve rotates.

D7 1s a pendulum bob on the lever D".

D8 is a set screw adapted to lock said pendulum bob in position on the lever D".

D9 is a recording lever projecting out# wa-rdly from the upper end of said sleeve DE.

D1 is a stylus carriage pivotally mounted on the end of said lever D and spring held downwardly against'the record sheet on the drum B1. l

D is .a stylus carried on said stylus carriage and resting upon said record sheet.

D12 is a dash, pot pivotally mounted on the sleeve C5 and connected by the link D13 with the lever D to damp its vibration.

It will be evident that, whilewe have shown in our drawings an operative device, still many changes `might be made in size, shape and arran nement of parts Without departing material y from the spirit of our invention. We wish, therefore, that our drawings-be regarded as in a sense'diagranunatic.

rlhe .use and. operation of our invention are as follows.: With.l our device in position on a train, boat, car or other moving vehicle or moving parts ot a moving vehicle the Fig.' 7 are,

is mounted suffers violent changes in direction the horizontal pendulum will swing forward-por back as the case may be andcause thestylus to swing across the record sheet making a mark on the record sheet. The

weight of the pendulum bob, its distance' from the axis of rotation and the tension of the spring will all be controlled or adjusted to provide for dierent forces and they will be calibrated against the record sheet so that, for instance, in case the mark goes overa certain distance it indicates a blow of 60,000 foot pounds'and for a lesser distance will be 30,000'foot pounds and a lesser distance might be 2,000 or less. It is, of course, obvious that the calibration may be madel to suit the convenience of the user.

The dash pot, of course, serves to damp the vibration'of the needle on the stylus so that only one swing will be made and the stylus` will be immediately returned to neutral position. Simultaneously, however, with the movement of the stylus in response v to the horizontal pendulum the vertical penduluml will swing and rotate the ratchet wheel driving the record sheet through an are subt'ended by one 'or two teeth as the case may be, thus feeding the record sheet forward and leaving it ready for a further record. By this arrangement, of course, a record is made only when important changes are to be recorded and the record sheet moves only when important changes are to be' recorded. Thus the life of the record sheet is very long as under favorable conditions very few records will be made, and it is not necessary to waste a whole record sheet in an 'effort to get one or two occasional indications as is the case of records into which the time element enters.

Our device is primarily intended for use on railroad trains and railroad cars, and it is necessary to find out only how often the engineer has started or stopped too suddenly. The time when he did itis of no consequence, since the devicel is inspected at the lend of each trip, and his record will depend only upon the frequency of such indications.

The record sheet is, of course, as indicated in Fig. 7, calibrated in foot pounds and it is only necessary to adjust the pendulum to correspond. The records shown thereon in of course, purely tentative and imaginary but are ofA such records as would 4 be produced in actual operation.
