TO ALL WHOMA IT MAYCONCERN:

Be it known that I, C. T. FITCH, of Harbor Creek, in the county of Erie, and Stateof Pennsylvania, have invented a new and useful Improvement in Machine for Driving Posts; and I do hereby declare that the following is a, full, clear, and exact description thereof, which will enable those skilled in the art fo makeand use the` same, reference being had to the accompanying drawings, forming part of this specification, in which-J` Figure 1 is a side view of a machine for driving fence-posts having my improvements attached. Figure 2 is a partial front view.

Similar letters of reference indicate corresponding parts. This invention relates -to improvements in a machine for driving fence-posts for which a patent was granted to me, May 7, 1864, which improvements consist in connecting the lower ends of the posts withfthe runners by means of hinges or joints to allow the head to be canted forwarder back, while thefront` bracesare also hinged i at their upper ends to the posts, and made to move at the lower endsfor temporary connection wi ners, to suit the position of the posts, by which arrangement theA machine will work on side hills.`

The general construction of the machine is the'same as that described `in of my patent aforesaid, the only change being made inthe parts referred to,

sist, and in dispensing with the -back braces, -which are rendered unnecessary. v

A A are the runners, and B B the posts connected to them at the foot by the hinge-joints a a. C C are braces on the front side of the posts B B, which are attached to them at at their lower ends are provided with shoes c c, placed apart to allow the braces to be moved, a as desired.

'lhe operation as well as the constructonvof the machine is in all respects the same as described in `my patent aforesaid, toA which reference is had, except in the improvements described.

Having described my invention, I claim as new, and desire to secure by Letters Patentl i i 'lh'e posts B, hinged by the joints a to' the runners A, when adjusted in any required position by` means their upper ends byjoints I b, and

of the staples and pins d passing through the slotted lower end of the hinged brace C, as herein described for -the purpose specified.
