Application led Hay 12, 1910. Serial No. 560,958.

To all whom 'it may concern:

13e it, known that I,r JOHN MCCLELMN, a citizen ot the United States` and a resident l() are pivotally connected by vertically extended pins 1l, ll to pitinen 12, 12. The pinnen 113, l2 are secured 'to crank pins 13,

The barsy 1f),

The ballasting of the road is performed iii the usual manner, either by dump cars or hand spreaders. The is deposited between the ties pended between liinnmoclts in the roadbcd. The machine having arrived at the scene of operation, the bar 1T is operatively connected to the bar S. This is accomplished v by assing. under the rails and ties et the j mit the passing of thc train having the right the standard l5 at one end of the bai` I of way. and thereafter returned to the bar roa 1T in such manner that the bar 1T is extendA ed below the ties and rails ot' the railway. '.l'lie standards 15, l5 are then raised and threaded through the perforaiions in the bar S provided to receive' the `said standards. In the position desired, and wherein i the upper side of the bar li' clears the under surface ot' the ties ot the railway, the set screws 1U, 16 are upset to hold in lixed relation the standards l5, 1.3, and the har 17 attached thereto. The machine is now in position to be operated.

The operation of the driving disks il through the pitmen l2 is to reciprocate the bar 8 in the slots 7, i'. The reciprocation of the bar 8 when the bar 1T is attached thereto results in reciprocating the said bar 17. The path of reciprocation of the bar 17 iscontrolled by the slots T, T. The reciprocations are produced by the rotation of the shaft 1t) through the transmission mechanism embodying the gears :20 and 2l, the wheels 23 and :2t and the chain 2o. yl`lie speed of reciprocation may bc varied, as is obvious, by changing the wheels 2() aud 2l to Vary the ratio in diameter between the two wheels. l

With each forward thrust of the liar li' the teeth 18 are forced through the intervening earth or rock ballast or bed, lifting and loosening the same, and depositing the saine to the rear of the said bar 1T and iii the path of the cleared shoulder thereof; vWith the return ol' the bar li', the said loosened ballast or earth is drawn rapidly and forcibly back and packed under the rearwardly disposed tie. 'l`lie reciprocationsA are at sulliciently short intervals to produce a comparatively constant action, therebyr performing the best work by tamping or par iing under the ties the ballast or earth iii small quantities at each operation, much iii the manner of hand tampiiig.

The leveling of the rails and ties connected therewith is the same as at presi-ni performed; and it will be noted that the weifrlit 'of the car body .'i. and mechanism carried thereby, also the weight of the loeo- A motive advancing the said :nai-bine, rests upon the tamped portion ol' the bed. the leveled and uiitainpcd portion of the bed being constantly l'orward oi" the body 5 and beneath the arms fl, Al of the taniping inachine.

Thereafter the tamping would proceed as if uninterrupted.

[t is obvious that in the operation of this machine. the humping or grounding of the roadbed is avoided.

llaving thus described my invention, what I claim as new and desire to secure by Letters Patent is l. A railroad tamping machine, comprising a wedge-shaped bar disposed beneath the railroad ties; supporting 'members for said bar; and a power driven reciprocating mechanism operatively connected with said bar.
