Manufactured by Smith & Hemenway Co. - Jamestown NY

Collar is capable of turning free in the bracket and degree of "frictional hold" is determined by the adjusting screw on the collar. This allows the feed to be regulated to the resistance of the item drilled and prevents too high of a rate of feed. Sandy Moss reports of his example: I have a chain drill that conforms completely to this patent, but is only marked with the month and day (Feb. 25). The chuck on the drill is marked, "S & H Co RED DEVIL". This is the Smith & Hemenway Co. of Jamestown, NY, the tools of which were marketed by the Crescent Tool Co. in the 1920s. The drill is not listed in the Crescent Tool Co. catalog of 1926, so was probably discontinued by this time. The drill is in new condition in its original slide-top box, with printed instructions. Note that it is equipped with a Barber type brace chuck, with alligator jaws. This differs from the patent drawings and the simple screw fixed chuck of the patent drawings.

Manufactured by Universal Mfg. Co. - Lincoln NE

Brace wrench with gear head to offset the line of motion. Inspired by "Ford 4th Connecting Rod Bolts." The driving shaft of the brace handle and connection of the end gear to the socket are Woodruff keys. The intention for this construction is that the handle and sockets could be removed and replaced. The extended length of the brace shank beyond the geared head is an essential feature that holds the head steady when the wrench was used. A known example is rusted and pitted so any manufacturer markings are obliterated. Manufacturer information obtained from a notice in a 1919 issue of "The Accessory And Garage Journal;" a 1919 issue of MOTOR AGE showed a different company name.

Manufactured by Brown & Sharpe Mfg. Co. - Providence, Providence County RI
Assigned to Brown & Sharpe Mfg. Co. - Providence, Providence County RI

This patent number has been seen on a Brown & Sharpe No. 5 surface grinder. Original application November 14, 9255 Serial No. 49,772. Divided and this application October 4, 1937, serial No. 167,190. Abstract: he present invention relates to improvements in grinding machines, and more particularly to operating and control devices for imparting translatory movements to a reciprocable work table of such a machine. It is a principal object of the invention to provide novel operating and control devices for driving the work table which will be readily adjustable to control the operation of the table for a wide variety of operating conditions which may include bath power and manual operation. It is a further object of the invention to provide a novel slowdown mechanism for the table which is rendered operative under certain operating conditions to insure an accurate and dependable control of table reversal. It is another object of the invention to provide in a table controlling and driving mechanism of this general description, a novel and improved dwell mechanism which is operative to secure a predetermined amount of dwell at each reversal in the direction of table travel. It is a further object of the invention to provide electrical operating and controlling devices for the work table, which may well form an integral part of an electrical operating system for the machine, and which are well adapted to insure at all times a dependable and accurate operation of the table over a wide range of operating conditions, as hereinafter more particularly set forth. Claim: In a grinding machine having a table reciprocable longitudinally for effecting relative translatory feeding movements of the grinding wheel and work, the combination with the table, of means for reciprocating the table between limiting positions at a uniform rate of travel and 20 for stopping and for starting the table from said positions, said means including an element shiftable to bring said table to a quick stop, adjustable dogs on said table to actuate said shiftable element, and an electrically controlled mechanism to start movement of the table in the reverse direction after a predetermined period of dwell.
