UNITED STATES EDwAED J. HOUSTON, OE NAOOOOEEE, GEORGIA, AssIGNOE OF ONE-HALE HIS RIGHT TO F. STARR, OF SAME PLACE.
IMPROVEMENT IN MORTlSlNG-MACHINES.
-Specification forming part of Letters Patent No. 135,917, dated February 18, 1873.
- To all whom it may concern:
a similar character requiring overhead springs to'cause the upward or return movement of the tool,) by which improvements such machines are rendered strictly portable and I do hereby declare that in the following speciiication is contained a full, clear, and exact descriptionn of my said invention, referencebeing had to the accompanying drawing and to the letters of reference marked thereon.
In the said drawing, forming a part of this specification, and which is a front elevation of my invention, A represents the frame of the machine. B are feet or stands, of sufficient length to give a firm foundation to the niachine without bracing or otherwise fastening it. G is a plank or light post, inserted within the rea-r foot B, andl further secured to the frame by an iron rod at a. The plank C ex tends above the frame of the machine to a convenient height, and acts as a rest or support for the spring. This consists of two wooden pieces, the lower one of which, d, is separated from the upper one, d', by the intervening piece e. The whole, as connected, is pivoted at e to the plank C. The lower piece d forms the spring proper, the upper piece d acting as a stiffener to the lower, the resilience of the spring being regulated as the shackle or link fis slipped toward or from the rear end there` of. The upper piece rests securely upon a pin, g', held between two posts, h, projecting from the frame of the machine, and which form a stirrup or guide to the piece d as it is (lepressed by the action of the foot upon the treadle D and in its return movement.
The spring, as described, bears the same relations to this portable machine as the spring ordinarily attached tothe ceiling of the room does to a similar machine necessarily xed therein.
I make no claim to the invention of anything relating to the mortising mechanism, to the -mode of operating the same, or to the frame of the machine, excepting to those features thereupon herein described. I cla-im as my invention- The combination ofthe plank C, springd d
