i invention lrelates to `means for. holdn l ing-'fa spike after it has been positiofl'ied for` driving and to means for subsequently driv ing. the spike.

5 The general object myinventionis to provide a mechanism for holding afspike and `for driving-1 the same, a more specific object being to provide. a spike holding mechanism and a spikey driving mechanism Je so cojordinated that the spike'drivingineans will function to 'trip Ithe spike y:holdingineclfianisrnvand'.permitthe'saine to move t'oQa position awayffrom the point offoperation of the driving .vmechanism. t i

'The arrangement is such that said spring 42 tends to. throw the latch 134 into a latching position. The latch 134 is released from the latching position `through the lmedium of the spike driving means as follows: The spike driving means includes a pneumatic hammer 44 of any v approved type, the numeral 45 in Figures 3 and 4 indicating the air hose of said pneumatic hammer. 46 on frame 27..

` head reaches a certain stageof. the driving` action so that the arms 32 may be released and be swung by spring 39 to a position away from spike a and away from the direct line of the Vhammer head 47 tov a'ord clearance for the hammer in driving the spike home.v` y l The hammer 44 is'fed downwardly'as follows :,Alever48 is fulcrumed at one end as at i 148 t'o frame 27 andhas an arcuate slot 49' in which movesA a 'lateral pin 50 on hammer 44, the arrangement' being such that the downward movement ofk lever 48 servesto feed the hammer downwardly. The hammer has a handle 51 for manually moving said 52 for the Vith the described arrangen'ient the truck embodying the described mechanisms is i brought into a position for the arms 15 to be caused Ito grip the tie A as in Figure 1. The lever 2O is then operated'toelose the y Vjaws l5 on, the` tie A.' after which thelever kof driving the spike.

While the spike is thus held, lever 48 lis operated to feed, the hammer 44 to a position' to operate on the spike a and the driving action of the hammer is continued untilthe'hammer head 47 trips the latch 134 as described, by engaging the member 41 to cause the arms 32 to move away from the path ofthe hammer, whereupon the downvwardfeed of the hammer is continued until the spike is driven home.

Il] hat is claimed is:

1 In a machine of the classfdescribed,

spike-holding means comprising' swingable arms toengage anddisengage the spike, and means on the driving means to vengage and displace the spike-holding means.

2. In a machine of the class described, a spike-holding means includingv swingable gripping arms having means to engage a spike, a lever, andconnections between the lever and said gripping arms to cause opening and closing movement of the arms by the operation ofthe lever. Y y 3. In 'a machine of the class described, av

spike-holding means including swingable gripping means having means to engage a spike,.a lever, and connections between the lever and said gripping arms to cause open- Y ing and closing movement ofthe arms by the operation of the lever;ftogether with spring means tending to exert an action lon oneV of the arms to cause opening movement of the arms.` Y i v 4. In a machine of the class described, a

pair of arms pivotedv to swingtow'ard oi7 from yeach other, means on .said arms Yto engage a spike for holding the saine while being driven, and latch' means to hold the arms in position withy the spike engaged thereby.v f

5. In -a machine of the classdescr'ibed, a pair Vof arms pivoted to swing toward or from each other, means on 'said' arms to engage a spike kfor holding the same while i being driven, and latch means to holdthe arms inI position with the spike engaged thereby together with spikedriving means',

ilo

and means engageable by the spike-driving" latch. y LUIGI VIEZZI.
