Bo it known that I, S. L. PORTER, of Rochelle, in the county of Ogle, `und State of Illinois, have invented a new und improved Device for Surfacing or Level-ling Railroad Tracks; endl do hereby declare that the following is n full, clear, and exact description thereof, which will enable others skilled in the nrt to make und use the same, reference being had to the accompanying drawings, forming port of thisspeeiiicution, in which...

This invention relates to a new and improved device for the surfucing,er levelling the tracks of railroads. 4On all railroads it is necessary to keepthe track level, 'indmen are constantly engaged in this service. The riiilsfhuve to he raised and the ties tomped for this purpose. Three men nre required -to do the worlcns new performed. By employing iny improved device for raising and holding o'reil'nt the proper level one. man will he dispensed with, and two men con. perform the'work as well in the seme-or less time.

This device is mede wholly of iron, and consists of e. strong, flot plote,'A, about*y sixteen inches long und eight inches brood, on the upper side of` which n'vertical slideplute, B, is fitted'to move heck and forth length# wise. It isslotted vertically and longitudinally, -so as to work on n. guide-hloek, a, that is made fest to the plate A. The slideplate B is set nearer one edge of the plnteAthnn the other, as shown in iig. 2; und the front e'nd is mode with n serios ofsquuresteps, ec, upon which the ruil rests when liftedfor levelling, :is hereinafter described. The sldefpl'ate Bis made eight inches long, and five high et the forward end. 0n the broader space, hy the 'side of the slide-plete B, n. quadruple fulcrum` is pivoted to vtho bottoni plate A, formed of Yfour urine l (Z, of dill'erent heights, as shown in iig. 3. The :prins oi' the fulornm nre made t-wo inches long, the lowest one half an inch high, and the others rising in gradution, half au inch, one above the other. Y

When used the As urfueing-hloel: is applied in this wise: rlhe earth or gravel is first removed with o. shovel d under the railto he raised, at some point between the ties, sufficient only to introduce the front end of the plate A underit, until the front end ol the slide-plnte B touches the rail, whenY it is set heck es fur :is it will'go, as shown in figs. 1' und 2. The crow-bnr is shaped with o bond or foot at tho bottom, ns show-n in red, g. 1. It is then'pleced with its heel on the lowest `nlcrnm-mm d, or the next :1hove,'if the purchase is required, und Vthe vrfi-il is raised to e level with one of the steps c, when, with his foot, the mim with the crow-har pushes the slidepluto B `forward till the step passes under tho rnil, to holdit there if the height is correct. Another man sights `the truck, und thus the ruil muy he raised and plitccd to rest on one of the steps f.' on the slide-plate B, the fuleiunrlieirig turned to give more or less purchase for lifting the rail, ne muy he required. The rail being thus supported hy the surfacing-block :it the required level, it ie only necessary to tnmp up the tics accordingly, by which, method of operation the ln'bor und time required for performing this work :tre mode less tha-nwhen perfornlcd in the usual way, without any provision for u fulcrum hut u. hloclf. orvstone, er some accidental support for the .crow-bar, noruny moans of supporting the rail independent of the lifting-hnr, which has to be held; or, the ruil is bloc-kerl up till the humping is finished. V v l lizwing thus described my invention, I claim as new, und desire `to secure by Letters .Patenty 'he bcdqxliltc A and the slide-plate 13, combined with 'n graduated fuleruin for levelling railroad tracks, constructed and operating substantially :is herein described.
