Assigned to The Adams Co. - Dubuque, Dubuque County IA

Abstract: My invention relates to variable-speed and reversing mechanism, and has for its object to provide a simple and efficient driving mechanism for use in connection with motor- vehicles and other machines in which the power, speed, and direction of rotation of the driven member are subject to frequent change, while the energy and speed of the motor-shaft are maintained practically constant, the changes in speed ,and direction in the driven member being effected by differential gearing connecting said member with the motor-shaft and with a speed-varying gearing driven from said motor-shaft. Claim: A variable-speed and reversing mechanism, comprising a driving-shaft, a hollow shaft geared thereto, a second shaft upon which said hollow shaft is mounted, a revoluble frame on said second shaft, a differential planetary-gear train connecting said frame with the hollow shaft and with said second shaft respectively, a gear from which power is taken connected to said casing, and means operated from said driving-shaft for varying the speed of said second shaft, whereby the frame and power-gear may be driven in either direction and at a variable speed.

Manufactured by The Adams Co. - Dubuque, Duduque County IA
Assigned to The Adams Co. - Dubuque, Duduque County IA

Abstract: My invention relates to milling-machines, with special reference to those having a horizontally-moving table upon which the work to be milled is chucked, and has for one of its leading objects to so set the milling-head and prov ide it with such means that it will have a universal movement in both a horizontal and vertical plane, whereby the work chucked upon the table and having a bevel or other angular surface may be operated upon at the different angles without rechucking the work upon the table or without providing other and special forms of cutters with angles especially adapted to attack the different angles of the work upon the table. A further purpose and thought is to adapt a milling-machine for cutting spiral grooves in drills, reamers, and that class of tools without swiveling or changing the position of the horizontally-moving table upon its base and have the work travel in the line of the cutters by arranging the cutters in the milling-head, whereby they will attack the work upon the horizontally-moving table at any angle. Claim: In a milling-machine, a supporting cross-rail, a saddle which is moved back and forth thereon, and an intermediate saddle which moves upon a horizontal curved line, combined with a bracket which is adapted to be revolved upon the saddle, and a spindle journaled in the bracket.

Examples of this drill are found around the world, from New Zealand to France to Canada. The actual manufacturer is unknown, though New Zealand researcher Sean McConnell reports seeing the drill in a 1930 catalog from Manufacture Française D'Armes Et Cycles De Saint-Étienne, a manufacturer and distributor of tools among many other items. Examples of this drill are variously marked "CC", "La Contal / Pte S.G.D.G. France et Etranger", the latter part meaning "Patented Without Guarantee of Government, France and Abroad". S.G.D.G. was a type of patent issued in France until 1968.

Manufactured by F. C. Wilson & Co. - Chicago, Cook County IL

Abstract: This invention relates to improvements in sheet metal crimping tools of that class employed for crimping the edges of sheet metal caps upon the flanged mouths of can spouts, and for other similar purposes. A crimping tool embodying my invention comprises in its construction a stock provided at its lower end with a part adapted to engage the upper surface of the sheet metal cap, and one or more crimping rolls revolubly supported, adjacent to the edge of said part, on the lower ends of downwardly projecting arms which are pivotally connected to the stock and are adapted to be oscillated to force the crimping rolls inward into position to bend or close the edge of the cap around or upon the flanged mouth of the can as the tool is rotated. In one approved form in which I have practically embodied my invention, said pivoted arms are adapted to be oscillated by direct pressure upon the tool along the axis thereof, the stock of the tool being to this end formed of two parts arranged to telescope together, or to otherwise slide longitudinally of each other, one part including a circular plate or disk which engages the upper surface of the cap and the other part including a shank to which any suitable handle or other device for operating the crimping tool is attached. Claim: A tool for crimping caps upon can spouts comprising a stock made of two relatively movable sections, one adapted to be grasped in operating the tool and the other provided with a cap engaging part, a lever pivoted to one of the sections and adapted for oscillation by the relative movement of said sections, and a crimping member upon the lever. Nozzle Cap Crimper. "The illustration shown herewith represents a newly invented tool for crimping the caps upon the nozzles of varnish and other cans, being introduced by F. C. Wilson & Co., can and tank manufacturers, 239 and 241 Lake Street, Chicago. It is claimed for this tool that it combines the lever and the wedge principle is so perfect a manner that little power is necessary in applying the caps, while the force exerted is so great that the nozzle and cap are joined so tightly that even the lightest liquids are perfectly retained. It will be seen from an inspection of the engraving that three crimping rolls are mounted upon a corresponding number of levers. The central spindle of the disk which fits down upon the nozzle cap projects upward into the stock, and the ends of the levers which pass through the stock rest upon this spindle. When the tool is pressed downward the spindle presses against the ends of the levers, carrying the crimping rolls inwardly against the work, and by revolving the handle the edge of the cap is turned over. As the upper end of the spindle is oval and the ends of the levers are beveled, the carrying the rolls against the work with wedge principle is brought into play, great force. The handle is of wood, the stock of brass, the levers of machine steel, and the rolls of the best grade of tool steel. The whole is very simple in construction, and the claim is made that it is not liable to get out of order. The tool is the invention of F. Cortez Wilson of F. C. Wilson & Co."
