Show i f af A RET INVENTION remarkable IDEA or A PENN 1 SYLVANIA GENIUS edward Ale mcgarvey Garvey of Helle Pelle tonte fonte hai t perfected a ala mac cl ine ln that III nil I 1 welsh weigh t trains while in motion ilow 4 1 work among the remarkable inventions patented this year is an electrical ap tor for weighing moving railroad trains by means of harmon harmonic le bibra lion and such attention on the pait of prominent electricians and me ban hall leal feat scientists has the invention al at ready attracted that it gives promie e of ranking among the gleat great things of the year the inventor is a bellefonte belief Belle onte fonte pa young man mr air edward Me mcgarvey Garvey and so confident are those who have closely investigated the claims of the invention that a company ot of prominent ers has been organized tor for the further per faction and development as well as to arjang for the manufacture not only of the weigh ng apparatus but also of va MR EDWARD al GARVEY several other similar inventions which will embrace the fundamental pie but applicable in various other equally important ways the principle of the invention la is entirely original it being the first of its kind ever presented to the patent authorities A full technical tion of the machine would occupy too much space but a brief review la Is in te resting the apparatus is composed of two small maL machines hines the ribbon cae and the recorder they can be at cached to any pair of scales railroad or wagon the principle Is harmonic vibration from electrical attachments and the work of the apparatus Is en ell automatic the working con fists in the attaching of a metallic rib bon to the scale lever or beam the other end to a fixed object when a weight Is placed on the scale the ten sion 1 on the ribbon naturally increases as the weight becomes heavier the electrical attachments cause the ribbon to vibrate and the number or rate of vibration varies according to the strain on the ribbon from de scale beam these vibrations are very rapid bard hard ly perceptible to the naked eye yet they open and close an electrical cir cult and in the sae s ae ne manner another 42 metallic ribbon Is ade to vibrate that Is placed on the same circuit har monic vibration is next applied it la Is a well known principle that mil mu steal reeds and strings will vibrate in unison when their particular tones are produced near them in the recording machine there Is a set ot of musical reeds the different weights c cause ause dit dif erent ferent reeds to vibrate A heavy load on the scales causes a high tension and a high rate of vibration of the metal ribbon and the result is a cor responding rate of vibration in the reeds the reeds are like the teeth of a comb starting from the lowest point as weight Is generally applied to the scale the reeds commence to v vi brate from the lower to the highest tones as the load increases A continuous sheet of paper passes under them and as each reed vibrates vibratos it makes a record on the chemically 0 prepared paper As each reed depre cents bents a certain weight the weight of the load Is thus automatically and cor erectly recorded the arrangement of circuits in the apparatus Is such that the recording mechanism may be re moved a distance from the scale and placed for instance in a railroad railroads s general office the regular telegraph line being used to conduct the im pulses the recorder will interfere in no way with the regular bL business sIness on the line nor will the operation of the regular instruments affect the accuracy of the records though the apparatus is as yet in the experimental stage it has been thor tho hughly tested at Belle tonte fonte conj was wa placed laced on the scales ot of the central railroad ol 01 pennsylvania at mill fall vall with the recorder in the office 0 of As distant superintendent john 3 walsh in bellefonte belief Belle onte fonte a distance ot of twenty nine miles and highly satisfactory re suits were obtained the practicability and merits ot of tha the system being fully demonstrated the tests were made with moving barq and it was shown that less than one second of time elapsed after the circuit closed until the ribbon and reed responded to the proper rate prom this and other practical tests it has been plainly demon that the feat of weighing a train moving even at regular trans speed over any properly constructed scales and of simultaneously recording the weight of the successive cars Is within the capabilities of this system the illustrations accompanying this article give a correct idea of the size of the apparatus ap aratus the hands of a man being shown in one picture the invention has already attracted the attention of large railroad and manufacturing companies who are anxious to give it a thorough test bellefonte Belle fonte however recognizes the merits of the apparatus and because ol 01 this the aforementioned company has been organized mr mcgarvey magarvey la 13 only twenty four years of age but has his demonstrated his ability as an inventive genius |
