|
Howard A. Pedrick |
Philadelphia, PA |
Abstract:
The object of our invention is to provide a strong and powerful machine for bending pipes and other shapes, and one in which the character of the bend can be readily varied by change in the relation of the fixed bearing element of the machine to the moving element of the same.
Claim:
In a pipe-bending machine, the combination of a hollow post split at its upper end to form a clamp, a head having a stem rotatably mounted in the post, a faceplate and its operating gearing carried by the head, and means for causing the split portion of the post to clamp the stem. |

The principals in Pedrick Tool and Machine Co. were Albert D. Pedrick and Howard A. Pedrick.
Abstract:
One object of my invention is to provide a simple, compact and conveniently portable form of boring head especially designed for use in reboring engine cylinders although by no means limited to this work, the invention particularly contemplating a novel arrangement and construction of the boring bar, feed screw and feed nut.
Claim:

Taper Boring Machine
|
Howard A. Pedrick |
Bala, Montgomery County, PA |
Abstract:
One object of this invention is to provide a novel mechanism for conically boring or turning the inside surface of a tubular structure, which shall be simple and substantial, as well as convenient to operate; the invention more especially contemplating a machine for cutting out a tapering cavity, which may be readily and quickly adjusted to vary the angle of the board or turned surface to the longitudinal axis of the structure operated on.
Claim:
The combination in a taper boring machine of a crank; a boring bar having one end pivoted to said crank; a bearing having a spherically curved recess; a spherically curved member mounted in said recess and formed to support the opposite end of the boring bar while permitting its longitudinal movement therethrough; and means for turning the crank. |

Feed Gearing
|
Howard A. Pedrick |
Bala, Montgomery County, PA |
Abstract:
This invention relates to mechanism for controlling the rate of feed of a cutting tool or equivalent device and more especially a tool carried by a supporting structure such as a rotary boring bar. One object of said invention is to provide a novel form of feed gearing particularly designed to permit of a quick and convenient adjustment whereby a cutting tool may be caused to feed at a relatively slow rate such as is required when using a drill to bore a hole in solid material or to feed at a faster rate as when it is operating on the inside surface of a previously formed hollow structure. Another object of the invention is to provide a device of the above character which shall be substantial in construction, not likely to get out of order and of such a nature that it may be readily applied to apparatus already in use without requiring serious alteration thereof.
Claim:
The combination of a rotary boring bar; a gear driven thereby, a feed screw; a spindle connected to said feed screw ; a second gear-'on the spindle having a number of teeth different from that of the first gear; a third gear meshing with the two first gears and mounted to move bodily : with means for holding the third gear from bodily movement to cause rotation of the first gear by the boring bar to turn the second gear and the feed screw. |

Boring Unit
|
Howard A. Pedrick |
Bala, Montgomery County, PA |
Abstract:
This invention relates to that class of devices particularly designed for boring the interiors of cylindrical structures as well as for drilling, reaming and similar operations and one object thereof is to provide a novel structure for adjustably supporting a power driven boring bar, whereby this may be quickly and conveniently mounted on or adjacent the structure to be operated on, in such position as to perform the work required.
Claim:
The combination in a boring unit. of a rectangular, hollow body structure; a pair of supporting feet on each side of. the said structure; means for adjustably securing the body structure to the said feet; upper and lower bearings in the body structure; a boring bar mounted in the bearings; a feed screw carried by the boring bar; a nut mounted between the hearings of the body structure; means for moving the not into and out of engagement with the feed screw; a plate pivotally mounted on the upper bearing: means for securing the plate in position; a frame mounted on the plate and carrying the driving mechanism for the boring bar; and means at the upper end of the boring bar for turning; the feed screw to move the boring bar longitudinally. |

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. |

Apparatus for Automatically Bending Work Such as Tubing Into Serpentine Coils
|
Ralph M. Shaw Jr. |
Edgewater Park, Burlington County, NJ |
Abstract:
he primary object of this invention is to provide a novel structure and assembly of means capable of adjustment to turn out single or multiple bends of conventional degree, as well as bends of unusual form, such bends being "set" and not liable to react but which will retain their intended shape. Another object is to provide a bending machine capable of turning out multifarious and diverse single or multiple bends of uncommon and varied character, with positive assurance they will be accurately shaped.
Claim:
In bar or tube bending apparatus for forming determinate shapes, a rotatable bend-effecting mechanism, means operative to shift the axis of rotation of said mechanism for directional control of its pivotal movement, an intermittently movable feeder for the bar or tube and a straightener feed-arresting device, said mechanism, feeder, and device being aligned; mechanism for timing operation of the aforesaid parts and means; and a control, synchronized with the timing mechanism, whereby the parts and means aforesaid are actuable to complete the desired bending cycle. |
