6 Claims.

This inventionrelates to apparatus for driving sheeting,stakes, piles or, the like and: aims to provideimproved apparatus of this kind embodying novelmeans forguiding or holding the-member to be driven.

Another object: of thisinvention is to provide improved apparatus. of this kind, in which a pair ofmembers defining aguidespace for the plank or the like to be driven, are shiftable to positions afiording, different desiredwidths for the guide space andin which novel clamping means is employed for holding such members inthe desired positions.

Stillanother object of the invention is to pro vide improved driving apparatus of this character, in which the guide members can be rigidly held in the desired adjustment without. likelihood of being jarred loose and in which there are no loose parts to become lost or misplaced.

Aiurtherobiect of the invention is to provide improved apparatus of the character mentioned, in which the novel clamping means for the shiftable. guide members includes clamps which are reversible for obtaining the desired difierent'spacings of .the guide members.

The invention may be further briefly summarized as consisting in certain novel combinationsand arrangements of parts hereinafter, described and particularly set out in the appended claims.

In the accompanying sheets of drawings:

Figs. 7 and dare detail sectional viewstaken on line ll. of Fig. 1 and further illustrating the change producedin the relative positions of the. parts by reversing one of 3 the. clamps.

In the drawings, to whichmoredetailed reference will now be made, I show my improved driv-' ing apparatus as comprising a percussive machine or tool I0 and a head or attachment I I connected therewith and adapted to receive an end of a plank I2 or other member to be driven. The tool I0 has an-elongated body-I3-containinga, cylinder, Min-which there is a reciprocable piston I5. The body I3; is provided at its upper end with a pair of:handles, I6 and-a valve actuating lover I! forcontrolling the actuation of-the piston I5 by compressed air, .or-other motive fluid, suppliedto the tool throughthe inlet connection I8.

The head or attachment: II has an opening or recess 20 therein adapted to receive the end of the membento be driven which,'in.this instance, isthe plank. I2. The head II also containsa movable anvil or strikerv 2I which engages the plank "and transmits thrustthereto from the piston 15-, as the result of blows delivered against theupper end ofthe-anvilby the piston. The head I I may also contain alubricant reservoir 22 andan upwardlyextending lubricant passage 23 for feeding lubricant from, the reservoir to the opening or guidewayinwhich the anvil 2| is slidablymovable.

-For-gui'ding or holding. the member I2 to be drivenand simultaneously retaining the driving apparatus for proper cooperation therewith, I provide apair of guide members 25 and26- which are connected with the. head I I by the bolts 2'! and provide a guide space 23*of a width to receive the plank I2, The. guide members 25" and. 26 are preferably substantially L-shaped members disposediwith thepair of legs 25a and 26a thereof in. substantially parallel relation to define the guide space 28aand-with theother pair of legs ZEband- 26b extending laterally. in opposite directions. and lying substantially in the same transverse plane. The legs 25b and 26b-areprovided withslots'39 through which the connecting bolts 2'! extend and whichslots are of a length to permit shifting of'the guide members for varying the width of the guide space: 281:9 correspond with different thicknesses of. the planks which are to be driven.- The leg 26b of the guide member 26 can, ifzdesired, be extended laterally as shown in thedrawings toform a foot restfor the operator.

In-Fig. 3 I show-one of the guide members. in this instance the guide member 26, moved inward ly to .the extent permitted by the slots 39 thereof so that the guidev space 28a'now defined by the legsv 25a and126a is of relatively. narrower width to receive the relatively narrower plank. 28a therebetween. In Fig. 4 I show both ofthe guide members 25 .andaZS moved inwardly to the extent permitted bythe slots 39'thereof so thatthe legs 25a and 26a define a still narrower guide space 2822 for the relatively narrow plank I2b.

It is highly desirable that the guide members 25 and 26 be securely connected with the head II with little likelihood for these guide members to be jarred loose. To this end I provide clamps 29 and 30 for the guide members 25 and 25 and which clamps underlie the laterally extending legs 25b and 26b of the respective guide members. The clamps 29 and 30 are in the form of an elongated bar or block having their upper longitudinal edges or corners rounded or shaped to conform to the curvature of the fillet 32 forming the junction between the vertical and lateral legs of the guide members. The clamps 29 and 3!! are provided with openings 33 which are spaced to correspond with the spacing of the slots 39 and throughwhich the connecting bolts 21 extend. The openings 33 of the clamps are located elf-center so that each clamp can be used in either of two positions; as

shown in Figs. 7 and8. The lower or under face of the clamps 29 and 30 have shoulders 34'thereon adjacent the openings 33, which shoulders cooperate with the heads of the connecting bolts 2! for holding the bolts against rotation.

In obtaining the guide space 28a of reduced width, as shown in Fig. 3, the clamp 30 is reversed with respect to its position in Fig. 2, and even though the leg 26a of the clamping member 26 has been shifted laterally toward the center line of the driving apparatus, one side and rounded corner of the clamp 30 will still engage the leg 26a and the fillet 32. In Fig. 4, in which both of the guide members and 26 have been shifted inwardly toward each other to obtain the relatively narrow guide space 28b, both of the clamps 29 and 3!] have been reversed with respect to their relative positions shown in Fig. 2 and the rounded corners 3| of both clamps engage in and conform to the fillets 32 of the guide members.

It will be seen from the foregoing description and the accompanying drawings that the clamps 29 and provide a firm and rigid clamping connection for the guide members 25 and 26 in all of the difierent adjustments to which these guide members can be shifted. It will be seen also that adjustment of the width of the guide space 28 can be very easily made since it involves merely the lateral shifting of one or both of the guide members, as permitted by the slots 39, and the reversal of one or both of the clamps 29 and 30. Likewise it will be seen that the clamps 29 and 30 have an extensive contact or bearing surface in engagement with the guide members so that these members will be rigidly held and there will be little likelihood of their being jarred loose. It will be seen also that in my improved apparatus all of the parts are in use at all times and there are no loose or separate parts to be mislaid or become lost while not in use.

While I have illustrated and described my improved driving apparatus in considerable detail it will be understood, of course, that I do not wish to be limited to the particular details and arrangements herein disclosed, but regard my invention as including all changes and modifications coming Within the spirit of the invention and the scope of the appended claims.

Having thus described my invention, I claim:
