Boring Mill and Mechanism to Oppose Sag in the Tool Bars Thereof
|
Ralph M. Shaw Jr. |
Edgewater Park, Burlington County, NJ |
Abstract:
With mills of the two-column types ordinarily used heretofore for boring operations, difficulty was had in keeping the bore true, particularly in machining relatively long objects such for example as gun barrels, due to the sagging of the bar or shaft along which the cutter head travels between the columns during the boring. Thus in these old forms of boring mills the span between the columns and hence the length of the tubes which could be cut was limited by the degree of permissible sag of the tool shaft, the maximum length of allowable span for a 6 inch tool bar for example in existing mills being approximately 12 feet. To eliminate or minimize sag, various expedients have been heretofore resorted to, such as employing tubular bars or shafts instead of bars or shafts of solid cross section to reduce weight; solidly anchoring the ends of the bars or shafts; providing tiedowns in the form of drawing mechanisms in the plane of the bearings for the bar or shaft; or to have followers move along with the cutting tools in snug engagement with the previously cut portions of the bores to hold the bars centered. The first two mentioned of these prior art schemes could not be relied upon for accuracy, and the last mentioned was objectionable because of the difficulty in disposing of the metal trimmings carried along by the followers without attendant scratching or scoring of the machined surface.
Claim:
In a boring mill, a pair of spaced columns; means for horizontally supporting a tube which is to be bored in the interval between said columns; a tool shaft supported axially, within the tube by bearings on said columns with, one end projecting beyond one of the columns; a third column with a vertically-movable bearing in which the projecting end of the shaft is engaged; and means for moving the bearing in said third column to variantly flex the projecting end of the shaft and so compensate for sagging of that portion of the shaft within the tube as the tool is advanced there along. |

Bending Machine
|
Ralph M. Shaw Jr. |
Edgewater Park, Burlington County, NJ |
Abstract:
The invention relates to machines useful in bending bar, tube and strip materials to different shapes. Bending machines as heretofore ordinarily constructed were more or less individually restricted in their performance to definite types of work. The chief aim of my invention is to enlarge upon the versatility of such machines so that different bending operations which heretofore entailed the employment of separate machines can be carried out in a single structure.
Claim:
A bending machine of the character described having a faceplate; la shaft about which the face plate is rotatable; means constructed and arranged `for driving the face plate; a master roller or die fast on the shaft; a pair of arms fulcrumed on the shaft and each carrying an auxiliary roller to cooperate with the master roller or die during the bending; and means whereby one arm is securable to the face plate for rotation and the other is fixable against movement. |

Food Preserving and Cooking Device
|
Ralph M. Shaw Jr. |
Edgewater Park, Burlington County, NJ |
Abstract:
This invention relates to food preserving and cooking devices, that is to say, to devices into which different foods essential to a complete balanced meal for one or more persons can be packed for preservation in a refrigerator until their use is desired and in which the foods are later cooked before removal. In connection with a device of the kind referred to I aim to provide for automatic cooking of the raw contents after removal of the device from the refrigerator. This desideratum is attained in practice, as hereinafter more fully disclosed, by embodiment in the device, of a heating unit and thermostatic control which is normally dormant at the temperature maintained in the refrigerator, but which, upon removal of the device from the refrigerator and exposure for a definite time to room temperature, automatically starts operation of the heating means for cooking the raw foods, those of the foods which it is desired to keep cold being protected from the influence of the heat during the cooking period by thermal insulation incorporated in the container structure.
Claim:
n a food preserving and cooking device, a receptacle for frozen foods having a hollow there-beneath; heating means within said hollow having-the form of a wick burner with a fuel reservoir of a capacity to insure complete cooking of the food in the receptacle; an electrical igniting means at the wick of the burner; and a normally-open thermostatic switch in circuit with the igniting means adapted, upon rise of the temperature within the receptacle to a predetermined degree after removal from storage in a refrigerator, to close the circuit for starting the burner. |
