Description
Sept- 9 N. C. HILL BORED CASTING HANDLING DEVICE Filed MarOh 9, 1951 Noel @Hill ATTORNEYS Patented Sept. 9, 1952 UNITED f STATES PATENT OFFICE This invention relates to a casting tool, and, more particularly. to a tool for facilitating the handling and movement of metal castings.
A primary object of the invention is the provision of an improved tool including a handle whereby a casting having a bore therein may be more readily lifted and moved as desired.
An additional and more specific object of the invention is the provision of such a device provided with an eccentric for gripping the interior of a bore in such casting.
Still another specific object of the invention is the provision of improved means whereby the tool may be readily disengaged when desired.
Still other objects reside in combinations of elements, arrangements of parts, and features of construction, all of which will be more fully pointed out hereinafter, and disclosed in the accompanying drawing wherein there is shown a preferred embodiment of this invention concept.
In the drawings:
Figure 1 is a vertical longitudinal sectional view taken substantially through the center line of one form of tool embodying features of the instant inventive concept.
Figure 2 is an enlarged fragmentary sectional view similar to Figure 1 disclosing the lower end of the tool in operative relation interiorly of the bore of a casting or the like, and
Figure 3 is an enlarged sectional view taken substantially along the line 3-3 of Figure 1 as viewed in the direction indicated by the arrows.
Similar reference characters refer to similar parts throughout `the several views of the drawings.
Referring now to the drawings in detail, there is shown at I a cylindrica1 member provided at its lower extremity with a vertically extending slit II. The upper end of cylindrical member I0 is provided with a transversely extending handle I2. A bossed recess I4 is provided centrally of handle I2, and is threaded at its upper extremity to accommodate a threaded plug I5 containing a bore through which extends an operating rod I6.
'Ihe rod I6 is provided at its upper extremity above the handle I2 with an operating button I'I which is gripped by the users hand in forcing rod I6 downwardly. The rod I6 is also provided with a collar I8 disposed below plug I5, the movement of the rod I6 and collar I8 being limited by the depth of recess I4.
The -rod I6 extends through a bore 20 in cylindrical member I0 secured interiorly to the side wall of cylindrical member I0 adjacent slot II and is adapted to engage an eccentric 22 which is pivotally mounted as on a pivot 23 seated in apertures in opposite sides of slot I I.
Normally biasing eccentric 22 to extending position outwardly through slot I I, and positioned on the opposite side of pivot23 from the extremity of rod I6 is a pin 24 which is biased downwardly by a Vcoil spring 26, the pin and spring being seated in a bore 21 interiorly of tubular member Ill and directly above slot l I.
From the foregoing the operation of the device should now be readily apparent. When it is desired to movea casting, as shown at 29, provided with a central .bore of a desired diameter, push button II is depressed which biases eccentric 22 against the pressure of pin 24 and spring 26 to the position indicated in dotted lines in Figure 1. The tubular member I0 is then inserted in bore 30, and pressure on operating button I'I released whereupon spring 26 and pin 24 bias the eccentric to the position disclosed in Figure 2, and in full lines in Figure 1, the point 3| thereof extending outwardly through slot Il into engagement with the interior side wall of bore 30. Simultaneously,
as lifting pressure is exerted on handle I2 the effect of point 3I is to bite into the interior of the bore while the heel of the eccentric simultaneously forces the opposite side wall of member I0 into frictional engagement with the opposite side of bore 30. Such engagement is retained as long as lifting pressure is exerted on handle I2, and when it is desired to release the tool from engagement with the bore it is merely necessary to press operating button I'I which again rotates the eccentric to the dotted line position disclosed in Figure 1 whereupon the tool may be readily withdrawn.
From the foregoing it will nowwbe seen that there is herein lprovided a device which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.
As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment herein shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.
In the claims:
1. In a casting tool a solid cylindrical member including a transverse handle and having a slot at one end thereof and a bore extending longitudinally therethrough, said slot extending angularly upwardly at one end thereof beyond the lower end of said bore, a lugpivotally mounted in said slot, a pointed extremity on said lug,
spring means normally biasing said pointed extremity outwardly of said slot, a rod extending through said bore, an operating button at one end of said rod, the other end of said rod normally abutting said lug on the opposite side of its pivot from said pointed extremity whereby pressure on said operating button serves to bias said lug into the upwardly angularly extending portion of said slot to retract the same within said cylindrical member.
2. The structure of claim 1 wherein the spring means comprises a bore having a closed end opposite the pivot of said lug from said first bore, a pin in said bore abutting said lug, and a cem- 4 Y pression spring between said pin and the closed end of said bore.
