This invention relates to a machine in which one and the same driving gear may be used for driving in nails for nailing boxes and for pulling out the nails of a nailed box,
the wood of the lid being not damaged and the nails being not bent isothat theymay be in. The frame of themachine is made of wood as shown, it might however be madeused again. I v I p I The machine, according to the, invention is diagrammaticallyshown, by way of example, in the'accompanying drawing in which Fig. 1 is a side elevation, partly in vertical section and v .Fig. 2 is a top plan view. In the drawing, 1 designates the lid on the box 2, 3 anail which has been driven into the box, 4 a nail whichisstill to be driven of thin-walled iron bars. I Iv The frame 5 rests on inwardly inclined feet 6 so that the devices for driving in or pulling outthe nailscan be brought as close as possible to thepoint at which the nail has to be driven in'or from whichthe nail has i to be pulled out, even if this point is near a corner. I
In the top end'of the frame a driving wheel 8 is rotatably mounted, the axle of the wheel being adapted to be driven by a crank handle 7. This wheel 8 has teeth 9 over half without teeth is one; tooth-i length shorter than the toothed portion. From the different lengths of these portions it. will be seen that, if the driving wheel is rotated one half revolution in the direction of the arrow'hne the rack 10 having teethon both'sides and slidably mounted in guidellis lifted, the
' teeth on the other side of the rack meshing make the gripper arms 16 grip the nail head a pressure has to exerted upon the machine frame or upon the portion of the driv-v ing wheel which has no teeth and which may be covered with leatheror upon the upper end of the raclrw'hich may also becovered. with leather.
The device for driving anail in is, during this operation, in the inoperative position;
The rotation of the driving wheel is pref- ,erably limited by stops.
The sleeve 24 might be fitted. with a device" for continually feeding nails into the same each time the ram 23 has been Withdrawn from the sleeve.
I claim A machine for driving in'and pulling out nails comprising a frame, a driving wheel rotatably mount-ed in the top end of said frame and having teeth in only one half of its circumference, a pulling+out device at one side of said driving wheel consisting of a rack meshing with the teeth of said driving wheel, a pair of gripper arms fixed on the lower end of said rack and an adjusting screw for adjusting the position of said gripper arms, a driving in device onsaid frameat the other side of said driving Wheel consisting of? rack carryinga ram at its lower end and 1 nailholdingmeans for positioning a nail beneat-h said rat m and an intermediate spur gear r0tatab1y mount-ed in said frame and meshlng With the'teeth of said driving Wheel and with the teeth f the nae]; Carrying said In testimony whei eofl af fi x signature; HANS SGHERM, R.
