Abstract:
My invention relates to improvements in caliper-squares for the purpose of measuring external diameters of shafts or cylindrical pieces, as well as for the purpose of squaring and measuring rectangular, square, or similar pieces of work that commonly occur in machine-shops or other works; and my invention consists of an ordinary graduated scale, provided at each end with a T-headed or similar recess, into which is fitted a T-headed or correspondingly-shaped screw- bolt, that passes through the head of a leg projecting from the extreme end of the scale in a right angle. The head of the said leg is provided with side lips or projections, that form a groove between them, in which the extreme end of the scale fits, at the same time as they serve to prevent the T-head of the screw- bolt from turning around or getting detached from the scale when the thumbnut that is used on the T-headed bolt is screwed up firmly to secure the square leg to either end of the graduated scale. In combination with the firmly- secured square leg in one end of the scale is used a movable leg, projecting at a right angle from the scale, and made to slide easily in and out on the latter, and provided with a set-screw, by which the said movable leg can be secured in any desired position on the graduated scale.

Improvement in cutter-holders for metal-lathes
|
Frederick D. Hazelton |
Boston, MA |
In 1877-79 the inventor was partner in Stone & Hazelton, who manufactured lathes and accessories, presumably including this invention. In the late 1890s, Hazelton ran a Philadelphia maker of switches and switchboards, F. D. Hazelton & Co. In 1902, motivated by problems he experienced in manufacturing knife switches, he invented a metal-cutting tablesaw. It was made by a new business, Hazelton & Donald Machine Co. They only lasted a year before selling the business to Hub Machine & Tool Co. |

Improvement in Metal-Planing Machines
|
Orril R. Chaplin |
Boston, Suffolk County, MA |
The inventor, Orril Reuben Chaplin, is best remembered for the Chaplin's Patent hand plane as manufactured by Tower & Lyon, patent 126,519, but he was granted a couple of dozen additional patents, for ball bearing journals, axle boxes, clutch, lawn mowers, shoe nails, and this metal planer.
Abstract:
My invention relates to improvements in metal-planing machines, and it is carried out as follows: I use, in the combination with a rocking frame or plates bolted together by studs, upon which the gears are held in position, and which frame is automatically rocked at the end of each stroke of the bed-plate, intermediate gears, and two additional gears in the rear of said rocking frame, so arranged as to run in opposite directions, and two half- gears secured to an independent shaft, for the purpose of imparting a half-revolution movement to the cross-feed shaft, so as to automatically move the cutting-tool forward at each end of the stroke. In combination with the aforesaid rocking frame and its gears, I employ a stationary bar or stop, against two opposite sides of which projecting ears on the rocking frame alternately strike when the said rocking frame is shipped, for the purpose of preventing the gears from bottoming into each other, and thereby creating unnecessary friction. The projections on the rocking frame are provided with set-screws, by which the exact rocking motion on said frame can be obtained and regulated.
Claim:
The combination of the rocking plates, s, s the pinions, zn, uc z, x, the half-gears, zv", x", the wheels, o, p, and intermediate gears, v v', rockshaft, y, and the head or block r. |
