I, An'rntn LIvINos'roNdJaNsLso, of Philadelphia, county of lhilz'ulelphia, State of Pennsylvania,have

-inventeda Ramining-Machine for ooden and other Pavements, of which the followinf,r is a specification.

Nature and Olgid of the I urcnun. l Myinventionconsists of' a 1amIning maehine, i'nlly,

'described hereafter, which has been designed especially for ra m ming the wedges of the Stow foundation pave ment. It lcan be used,`ho\\ever,`tbr ramming, thehloeks 0r fillings of any wooden pavement, and, on being slightly modifieihmight also be adapted to the rai-mining of eohhle, granite, or other. stonepavenient.

Description. of the Accompanying Drau'iny. Figure l, sheet 1, is a vertical sectional view oi'my ramining-machine foravooden Aand other pavements;

= of wheels, B and C, placed at'riglit angles to cach other, and arranged, as hereafter described, to support the machine alternately, the-latter resting upon the wheels B `when it is to be moved longitudinally, and upon the wheels() when inis to' befmoved transversely.

The `several partsof themachine, as 'well as the supporting-wheels, am intended to be 'driveiby a.

steanifengine, which is mounted -npou the 'frame A,

. the motion being, inthe first place, imparted to a driving-shaft, 1),'whielr turnsin suitable ,bearings in vthe. upper part.- ot`- the fra-mc.

- The driving-shaft is furnished with two bevel-wheels,

ailgwhich 'gear into berel-wlieelsa' sfof two shafts, E

.1 'Each of the'latter is provided with-two bevel-wlreels,` b.b','arranged to' slide on the shaft, but prevented from vturning independently of the same.

The sliding motion isc'ommnnicated simultaneously 4Vtothctwo sets of wheelsb b'by meansot' chltch-le-- jvers F.F`,'ope'rated by a rod, F; anditho object of the arrangement is toenable the direction of the motion .imparted to vertical shafts G G bythe' said bevels wheels tolle changed/at pleasure..

' Each shaft G'islfurnished at its lower'cndavith a' bevel-wheel," c, which gears into 'a bevel-wheel, c, of-

the spindle, to' which one of the propellingwheels BA is lined; and-the; said bevel-wheel. c gear'sfisofuuden the eircnn'istanees described hereafter, into .a -bev'clwheel, c, of the spindle il, Jto which thev transverse propelling-wheels C are hung.

The spindles of the wheels B are hung directly-'t0 the frame A,.so thatt-he bevelfwheels cl remain couslantlyin gear with the wheels c of the upright shafts Gr; but, as the transverse wheels C, with their spin- -dles, require to be raised or lo\vere( l,"according as the machine is to bcisnpported upon them or upon Athe longitudinal wheels B, it follows that their cogwheels i cnin'st be thrown ont of gear when the said transverse wheels are raised.

which .the spindles pass.

`llie plates H are operated, simultaneously, by

` means ot' rods f, whichare pushed Ainward' when the wheels C are to be raised, and drawn outward when the said wheels are to be lowered, and the wheels B, consequently raised.

The hammer or 1'an1"I, by which-the wedges x are driven down between the blocks 3'/ of the pavementfis; arranged to slide.` between' veiticaljguides--f of the i frame of` iliemachine, the said'ram. receiving its mo- `tion', through the medium ofa' connecth g-rod, g,`from' a crank-shalt, J, which has two sets of astand-loosc pulleys, "gr g', connected, by chainfheltslr, with pulleys 7|.olrthe driying-shaft D." i The ram- I does not actdirectly. upon the wedges a:

' of the pavement,- but' thronghthe medium-.of a heavycast-iron swage, K, also arranged to'glide in the guides fof the frame, and having, onl its under side, a number of .wrought-iron projections-.or ribsr'i,` adaptedl to' the spaces between the blocks. f

' In' order to prcventinjury tothe machine incase the rain should meetwivith any undue resistance in anni @eine i strikingthe'swage, it isinecessary that thecrankislunt J should 'have adjustablebearingseapable of yielding vertically toa limited extent when the blow is struck.V To e'eet this; object, and also4 to4 preventl the shaft,

. when mliusterhfrom .being thrown" o'ut vot' gearwitlr `the driving-shaft, segmental guides L, secured to or forming part of the frame A, 'and formellen u o'urve dcscribedi'om t-hefcenterof theV said driving-shaft,

Frames M,' rendered verticali y adj estable' by eetscrows'j, are arrangedwithineach of the segmental guides, and in these framesarc-nrranged toslide the 'boxes k, in l which tho: crank-shaft J turns,tho said-- boxes being maintained i'npositisn both-above and below, bmtrong ,spiral springs l, high-permit the necessary vertical yieldingpfy tho'crank-shai.

1n order to Venable the swage 1i' to'bc raised from the spaces between the blocks ot' the pavement when the machine isto be moved, the said swagc is providtal with arms-1n, which project upward to a point above theA upper face oithe ram. These arms are notched .on their inner edges, as bestobscrvcd in figs. 3 and l, in order to. admit the ends of bolts p, arranged to slide on the upper face of the ram,I the said bolts being op- I erated simultaneously, in the present instance, by a rod, q, attached to a loose collar, q', which turns on the stem e' of the ram, and which is connected to the bolts by links r.

When the bolts are inserted into the notches of' the arms mjot' the swagc, the latter must bc lifted with the ram, and when the swage is to be'again used, the bolts can be withdrawn and the said swagepermitted to fall by its own weight.

Operation. l

"lhe machine having neen moved to the desired pbsition uponA the pavement, the bolts 1l are withdrawn from the notches in the arms ofthe ram, andthe latter is permitted to fall until its ribs or projections i cnterthe spaces between the blocks andrest upon the wedges to be forced down. 'lhc propelling-wheels -are `then thrown out ot' gear, and the wheels C are raised or lowered, as the case may be, until they are on the same level as the wheels B, they being then secured -in this position, in orderthat-the machine may'rcst upon both sets of wheels. and" be. thus supported with perfect steadincss. 'lhe belts are then shifted from the loosev onto the fast pnlleysot' the crank-shaft J, when a rapid vertical reciprocating motion will be imparted to the ram, the -la`tter dealing a succession ot blows upon the upper face'oftlie swagc; and forcing the ribs t oft-he same, and, eouscqnentl y, thepvedges, downward' into the spaces between the blocks.

'lhc arrangcmem; ot' lthe sliding boxes h and spiral4 springs l permits the c 'ank-shaft andram to become gradually depressed and follow the lswage as it is caused to descend.

lhe boxes M'can also bev adjnsted,'1rom time to time, by means of their set-screws j, when it is necessary to change the position of the crank-shaft in order to render the blows of the ram moreetleetive.

After ramming down a row of wedges, the swage is connected to the ram lby means of the bolt-s p, and is raised with the same, the crank-shaft being then thrown out of gear,and the ram and swage'maintained in .theirraised position by any Asuitable arrangement ot' catches. 'lhe machine is then moved, either longitudinally or transversely, t0 the required' distance, by causing it to rest upon the proper set of propelling' wheels. and throwingpthe. latter' into gear, as before described; and, when brought to a proper position,

`the machine is again stcadied, as before, and the op- 'eration ot` rammingl resumed..

"lheribsi mightfbe c ast inone piece with the swaj'c, but 1 prcf'er to malte them of wrought-iron, as betere .mentioned lnsomecases,howcv '---as,forinstance,

in ramming steile pavements or wooden.pavements diiie'ring from th'e Stow-'`the ribs on the under side of the swage might be altogether dispensed with, or befniade oi'. a shape diti'ering from that described. In other instances, also, it might be found advisable to strike the blocks with the ram directly without the intervention of a swage; but I prefer to employ the latter.

Claims.
