Listed in A List of Patents Issued by the United States, from 1790 to 1847, pgs. 60 & 388. Abstract: This improvement in the manufacture of spoons consists in plating and cutting a bar of silver in the shape, thickness and just proportions of a spoon by means of a mill in all its outlines precisely like a common plater's mill. A common plater's mill with eight inch rolls may be converted to this purpose, and as these are in common use, and well known, further description is deemed unnecessary. The drawing exhibits its appearance. The first operation of this mill is to take a bar of silver, about half an inch shorter than the spoon required. This must be rolled through widthwise, the bar of silver should be very little thicker than the thickest part of the spoon handle required, and as wide as the handle at the shoulder. One end of this bar will then be placed directly over the center of the rise, or peen marked a, upon the upper roller, and the mill turned, and it will come through plated, and widened at one end in the shape of a spoon bowl, and at the other widened like the fiat part of a spoon handle. Claim: The shaping of a roller of a common plater's mill, so that it shall receive a bar of silver widthwise, and roll it into the shape of a spoon, one end for the bowl, and the other for the handle, leaving the bowl in its proper shape with the silver thickest at the edges and thinnest in the middle, and this to be made separate from though designed for a cutter.

Manufactured by Monarch Machine Tool Co. - Sidney OH
Assigned to Monarch Machine Tool Co. - Sidney OH

This tool changer seems to have been originally developed for Edlund Machinery Co., Inc., but that company was acquired by Monarch shortly before the patent was issued. Abstract: The present invention relates generally to machine tools and more particularly to an improved tool change mechanism for changing a tool at the operating station of a machine. In a machining operation where a large number of holes must be accurately bored, a jig boring machining is utilized to drill or bore these holes with a high degree of accuracy both as to location and to hole diameter. The use of these boring machines requires time consuming and laborious preparation by highly skilled operators which therefore requires 'both a large outlay in labor and time of skilled mechanics. Present day computers and programming techniques have helped solve many of the problems in precision machining operations; however, in automatic machining operations, where a minimum amount of supervision is employed, breakdown due to jamming of parts, which may result due to error on the part of the machine operator in set up of the machine can have a costly and disastrous effect. In the present invention there is provided a tool change mechanism readily adapted for automatic or programmed operation and which avoids the problem of manual insertion of tools while permitting rapid removal and insertion of tools at the operating station of a machine tool, such as a boring, tapping, milling or drilling machine. Claim: A tool change mechanism for changing a tool at the operating station of a machine comprising: a tool transfer station disposed for receiving tools that are to be transferred to the operating station of a machine, tool transfer means at said transfer station carried by the ma-chine, said tool transfer means including tongs having a pair of arms pinioned at an intermediate position on said arms and disposed for movement in a pair of perpendicular planes, air means connected to said tongs for opening and closing said tongs in one of said planes, motive means including a rack and pinion connected to said tongs for rotating said tongs in the other of said planes whereby said tongs are carried to grasp said tool when said tongs are closed and transfer said tool in an arcuate path upon energization of said motive means to transfer said tool from said tool transfer station to the operating station, a cam surface connected to rotate with said pinion, means arranged for engagement with said cam surface to displace said total transfer station a distance less than approximately 25°, and means at said operating station ranged to receive said tool and operatively retain it therein.

Assigned to Remington Standard Typewriter Manufacturing Company - New York NY

Specialty pliers designed to align the type-bars of typewriters. The alignment is accomplished by slight bends of the shank of the the type-bars. The same principle could be altered in scale for bending or straightening lighter or heavier metal. They are noted as "Nine prongs" in works on typewriter maintenance and repair. A known unmarked example is seven inches long overall.

Abstract: This improvement is designed to obviate the defects experienced in Mr. Beard's spring (patent #8884X), and consists in having the frame containing the spring made in two parts instead of one, the second part being made 1G movable by screws designed to tighten the web, and regulate the spring when settled down or sagged by long use, without being obliged to tear the saddle to pieces or substitute a new spring. Claim: The addition of the two screws for raising the webbing when required.
