COMBINATION SCRIBER AND PUNCH Filed Sept. 12, 1962 INVENTOR. Dennis W Gragan Afforney Patented Oct. 13, 1954 3,152,396 COMBINATION SCRIBER AND PUNCH Dennis W. Grogan, 418 36th St. NE., Cedar Rapids, Iowa Filed Sept. 12, 1962, Ser. No. 223,094 2 Claims. (Cl. 30164.9)

The present invention concerns a scribing tool, and more particularly a scriber for layout of large templates on metal or similar material.

The layout of large templates on large plates or sheets of metal is an arduous job. In the past the practice has been to place such templates and the work upon a large table and to use a relatively short scriber, merely a pointed tool with a brief handle thereabove, in one hand while holding the template if necessary with the other hand. In such a case it is often difficult to achieve sufi'icient pressure with one hand on such a scriber, especially when the layout man must reach across the template, to do a proper job. If, instead, the work is not moved to a table, then the layout man must be down on his hands and knees with the additional consequence of increased fatigue. The present invention eliminates the need to remove the work to a table and additionally permits the layout man to stand relatively erect upon the template, his weight helping to maintain the template in a contant position on the work, and to scribe along the edges of the template with as little effort and change of position as possible. Accordingly, with the present invention a layout man can accomplish his job more easily and accurately, as well as with less fatigue, than with presently used devices.

Essentially, the present invention utilizes a main, polelike handle which may be grasped by either hand of the layout man when standing on the template. A pair of resilient brackets extend in opposite directions outwardly from adjacent the lower end of the handle. A pair of scribes in turn are clamped to the brackets at their outer ends so that the scribes extend downwardly to engage the work when the scriber is operatively grasped by the layout man. An additional or auxiliary handle extends upwardly from the outer end of each bracket and is grasped in turn by the other hand of the layout man. The scriber can thus be used on work at each side of the layout man without requiring him to shift position on the template, but instead merely to exchange hands on the main and one of the auxiliary handles. A usable tool, according to the present invention, would also be provided if but one bracket and scribe assembly were formed on one side of the main handle and a single auxiliary handle on the other. However, the provision of two scribes and auxiliary handles increases both the utility of the tool and the length of its use between resharpening of the scribes. The latter, according to the present design, may be simply discarded hacksaw blades or the like, sharpened to a point at one end, in order to avoid the need of special, more costly ones. Finally, an anvil is provided at the lower end of the main handle and a center punch at the other or upper end thereof, whereby when the location of a hole in the template must be marked on the work, the scriber may simply be inverted and the hole marked by a hammer blow on the anvil. When a hole must be marked while using present types of scribers, it is necessary first to put the scriber down and then pick up a separate center punch and hammer.

Accordingly, the primary object of the present invention is to provide a scriber of the type described utilizing a main handle having a bracket extending outwardly on one side thereof near the lower end thereof adapted to carry a scribe thereon and an auxiliary handle extending outwardly from the other side of the main handle.

A further object of the present invention is the provision of a scriber of the kind described incorporating a pair of scribes secured to brackets extending outwardly from opposite sides of the lower end of a pole-like, main handle, the outer ends of the bracket being provided with a pair of auxiliary handles extending upwardly therefrom.

Another object of the present invention is to provide a scriber of the kind described which utilizes a pair of discarded hacksaw blades as scribes.

A further object of the present invention is to provide a scriber of the kind described incorporating an anvil and center punch at the upper and lower ends, respectively, of a main, pole-like scriber handle.

Other and further objects, features and advantages of the present invention will be apparent from the preferred form thereof, hereafter described, read in conjunction with the drawing, which represents a plan View of a scriber according to the invention, certain portions being broken away.

A main, pole-like handle 10 is provided with a knob-like anvil 11 at its lower end integral therewith and a center punch 12 at its upper end. The latter has its remote end butting upon a plug-like seat 13 formed in the upper end of handle 10 and extends therefrom, its operative end being necked down to receive the smaller end of a frustroconical collar 14 thereover whose larger end is threaded upon the upper end of handle 10. The latter is preferably hollow, of a diameter so that it may be conveniently grasped by one hand of the layout man and of a length so that it may extend down to the work when the layout man is standing upon the template in a slightly forwardly leaning position. Any suitable material, such as a length of pipe, may be used for handle 10, but it must be stout enough to withstand and to transmit hammer blows on anvil 11 to punch 12.

A pair of preferably resilient brackets 15 are attached to opposite sides of handle 10 just above anvil 11 and curve outwardly and upwardly therefrom, being provided at their outer ends with a pair of oppositely disposed clamps 16. The latter may be formed from suitable tubing in the shape of open rectangles lying in the plane of handle 10 and are angled with respect to the axis of the latter so that their lower sides 17 are spaced further apart than their upper sides 18. The outer sides 19 of clamps 16 are extended upwardly and outwardly therefrom and are internally threaded at their upper ends to receive the lower ends of auxiliary handles 20, 20, extending in turn upwardly therefrom in the plane of handle 10 and inclined outwardly thereof. The upper ends of handles 20, 20 are bent inwardly toward handle 10 to provide opposed hand grips 21, 21 on each side of handle 10. The lower and upper sides 17 and 18, respectively, of clamps 16 are provided with longitudinal slots therethrough in the plane of the axis of handle 10, which slots are connected by complementary slots in the inner faces of outer sides 19, in order to receive a pair of scribes 22, 22' therein. The latter are formed from discarded hacksaw blades or the like, sharpened to a point at one end, and incline downwardly and outwardly from clamps 16 owing to the angling of the latter with respect to handle 10. Scribes 22, 22' are adjustably secured in clamps 16 by means of set screws 23, or the like, which pass through the inner sides of clamps 16 and bear on the inner edges of scribes 22, 22.

It will be appreciated, of course, that handles 20, 20' must extend upwardly far enough so that when main handle 10 is grasped in, say, the right hand of the layout man standing in position on the template and, for instance, scribe 22 is operatively engaged to the left of the man, hand grip 21 may be conveniently grasped by his left hand. When work has been completed on his left side, his hands are merely interchanged on handles 10 and 20' so that he can then scribe the work to his right. When the other scribe 22' is employed, then the other hand grip 21 is used in a corresponding manner.

While the present invention has been described with reference to a particular embodiment and detailed descriptive language has been used, it is not so limited. Instead, the following claims are to be read as encompassing such modifications and adaptations of the invention as would ordinarily occur to one in the art.

I claim:

1. A manually manipulatable scriber for laying out large templates on metal or the like comprising a rigid, pole-like main handle adapted, when grasped by one hand of a layout man standing on a template in a forwardly leaning position, to extend downwardly in front of said man to adjacent the template, a scribe assembly disposed on one side of said handle and attached thereto adjacent and slightly above the lower end thereof, said assembly including a resilient bracket extending outwardly from said handle, a pointed scribe, a clamp at the outer end of said bracket securing said scribe so that it points operatively downwardly therefrom in a direction diverging outwardly from said handle, and an auxiliary handle extending outwardly from the said main handle, the length of said auxiliary handle being such that when it is grasped by'the other hand of the layout man, said scribe is in its operative position relative to the template when said man is in his aforesaid position.

2. A manually manipulatable scribe holder for use with pointed scribes for laying out large templates on metal or the like comprising a rigid, longitudinally extending main handle adapted to be grasped by one hand of a layout man when standing in a forwardly leaning position, substantially identical scribe support brackets extending from opposite sides of said handle adjacent and slightly above the lower end thereof, each of said brackets having means at its distal end for removably securing thereto apointed scribe so that it points operatively downwardly therefrom in a direction diverging outwardly from said handle, and an auxiliary handle extending outwardly and upwardly from the distal end of each of said brackets, the length of said auxiliary handles being such that when the auxiliary handle on one side of the main handle is grasped by one hand of the layout man and the main handle is grasped by the other hand, the scribe on the side of said main handle opposite to the grasped auxiliary handle is in its operative position relative to the template when said man is in his aforesaid position.
