Application June 30, 1955 Serial No. 519,166
PARALLEL 2 Claims.
This invention relates to a parallel clamp.
It is an object of the present invention to provide a parallel-clamp which will be suitable for securing thin sheet material to a surface for the purpose of being drilled or worked upon.
It is another object of the invention to provide a parallel clamp wherein the ends of the jaw members are shaped to receive plate members having a series of holes through which a drill can be extended to penetrate the thin work piece held between the jaws.
It is still another object of the invention to provide a parallel clamp with plate members adapted to fit the ends of the jaw which, when not in use, on the ends of the jaw, serve as the hand knobs or wheels that are connected to the ends of the screws and by which the screws canbe turned and wherein upon removal of the hand knobs or wheels for use on the ends of the jaw, hand rod means i will be provided upon the screws to eifect the turning of the same and wherein these rods may serve as the driving connection of the hand knob or wheel with the screw.
It is a further object of the invention to provide a parallel clamp wherein the ends of the jaw members are shaped to fit in small places upon the work piece so as to permit the jaw members to be located close to the point where the drilling operation is being performed.
Other objects of the invention are to provide a parallel clamp having the above objects in mind which is of I simple construction, inexpensive to manufacture, has a minimum number of parts, easy to convert from one use to another use, has no surplusage, durable and compact, easy to operate, of pleasing appearance, eificient and effective in use.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:
Figure 1 is a perspective view of the parallel clamp embodying the features of the present invention;
Fig. 2 is a side elevational view of the parallel clamp with the plate members removed from the screws and connected to the jaws in order to adapt the clamp for use in securing thin material, while being worked upon through openings in the hand wheel plate members;
Fig. 3 is an enlarged elevation member looking upon the work surface of the holding plate and as viewed on line 3-3 of Fig. 2;
Fig. 4 is a transverse sectional view of the holding plate and jaw as viewed on line 4-4 of Fig. 3;
Fig. 5 is a sectional enlarged view of the clamp plate applied to the screw to serve as a hand knob or wheel for turning the screw and securing the work piece, the view being taken generally on line 5-5 of Fig. 1.
Referring now to the figures, and 11 represent opposing jaw members which are held together by parallel and vertically-spaced hand screws 12 and 13. The hand screw 12 has a fixed collar 14 that is rotatable in a recess v 25 in the jaw member 11. opposite direction from the screw 12 and its handle end 2,886,080 Patented May 12, 1959 ice 15 of the jaw member 11. This screw 12 is journalled in the jaw member 11 and is held against outward displacement therefrom by a washer 16 and a hand turning pin 17 extending through rear extension 18 of the screw 12. A hand knob or work-retaining drill plate 19 is secured to the rear extension 18 by a screw 20 that is secured to a threaded hole 21 in the end of the rear extension 18. In this manner, the screw 12 is held in the jaw member 11 against axial displacement. Turning of the screw causes jaw member 10 to be moved upon the screw being turned through threaded opening 22 in the jaw member 10.
The hand screw 13 is operable through threaded opening 23 and has a reduced end 24 that is turnable in a hole The screw 13 extends in the has a threaded hole 26 into which a screw 27, Fig. 5, similar to screw 20 is inserted to fix hand knob or work retaining plate 28, similar to hand knob or work retaining drill plate 19, upon the end of the screw 13 to serve as. a hand knob. A hand pin 29 extends transversely through .the screw 13 adjacent the knob 28 so as to lie within a diametrically extending recess 31 in such a manner as to provide an operative connection with the sides of the recess, if necessary, for perfecting the connection of the hand knob 28 with the screw 13 and also to serve as a means by which. the screw can be turned when the hand wheel is removed from the screw and used as a work-retaining drill plate to engage the work. 30
When it is desired to use the hand knobs as drill plates adapted to engage the work piece, the respective screws 20 and 27 are removed fromthe ends of the screws 12 and 13 and the hand knobs or plates 19 and 28 are fitted on the work engaging ends of the jaw members 11 and 10. Hand knob or drill plate 19 also has a recess 32 in its underface, Figs. 3 and 4, and the sides of this recess are adapted to be engaged by the transverse hand pin 17 when the hand knob or plate 19 is fixed to the screw 12 to turn the same. The screw 20 is then used to fix the plate 19 upon the end 33 of the jaw member 11 against inward displacement therefrom and against longitudinal displacement along the jaw member. To receive the screw 20 is a threaded opening 34 in the end 33 of the jaw member 11. The plate 19 has a series of different size holes 35 extending therearound through which a drill tool can be extended to perform work upon the thin work piece being retained between the jaw plates 19 and 28. The jaw plates 19 and 28 can be placed on the jaw ends in either one of two positions t which are permitted by the recesses 31 and 32 so as to present difierent openings 35 adjacent the tip end of the jaw member and at the opposite sides thereof. The tip ends of the jaw members as indicated at 36 are curved inwardly to permit the ends of the jaw members to be located close to the point where the drilling operation upon the thin work pieces is performed. The screw hole 34, when not being used to attach the drill plate to the end of the jaw memher by the screw fastener, will serve as an opening through which a mark on the work piece can be observed and through which the drill can be extended to effect a drilling operation upon the work piece.
The drill plate 19 has serrations 38 to provide a good hand grip upon the plate when the plate is to be used as the hand knob or wheel for the screw. When the drill plates have served their purpose in drilling the work pieces, they may be returned to the screws 12 and 13 and made secure again thereto by the fastening screws 20 and 27.
The jaw member 10 has a tapered end 39, a threaded hole 40 for receiving the screw 27 and a relieved end face 41 to allow the jaw member to be brought close to the point of the drilling operation upon a work piece. The
hand knob 28 or jaw plate is similarly attached to the jaw end 39 the same manner as the jaw plate 19attached to the end 33 of the jaw member 11. The hand pins 17 and 29 serve as turning means for the screws when the drill plates are removed therefrom and also serve as a drive connection for the drill plates when fixed to the screws 12 and 13 to serve as hand knobs. The hand knobs when used upon the screws permit hand tightening of the screws with less effort than when the hand pins 17 and 29 are used for this purpose. In normal use the clamp will be used without the hand knobs being disposed on the jaw members. But at times when thin material is to be drilled the hand knobs are readily available from their storage location on the screws and can be readily applied to the jaws by the same fastening screw by which they have been secured to the adjusting screws.
It should now be apparent that there has been provided a parallel clamp with hand wheels or knobs which can'be converted into jaw or drill plates and secured to the ends of the jaw members for serving as a guide for drilling operations upon thin sheet material retained between the plates. It will also be apparent that pin means are left upon the screws to efiect the turning of the screws when,
the hand knobs or jaw plates have been therefrom. It will be apparent that this is efiected with a minimum number of parts and that there is no need for auxiliary pieces for so converting the clamp into one having a heavy jaw plate on the ends of the jaw members and that all of the parts have a function upon the clamp regardless of whether the clamp is being put to normal use or to a use requiring the drill plates to be attached to the ends of the jaw members.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
What is claimed is:
1, A parallel clamp comprising a pair of jaw members,
a pair of parallel adjusting screws extending between the jaw members and'adjustable to move the jaw members toward or away from each other into clamping or unclamping positions, each adjusting screw having a transversely extending hand pin as a screw turning means, and a work-retaining drill plate as a removable jaw attachment adapted to be adjustably secured on the end of each jaw member, said drill plate having perforated portions extending past the side walls of the jaw members.
2. A parallel clamp comprising a pair of jaw members, a pair of parallel adjusting screws extending between the jaw members and adjustable to move the jaw members toward or away from each other into clamping or unclamping positions, each adjusting screw having a trans versely extending hand pin as a screw turning means, and a work-retaining drill plate as a removable jaw attachment adapted to be secured on the end of each jaw memher, said drill plate having a recess therein extending along one side thereof and said work-retaining drill plate being adapted to be removed from its jaw member and placed on an adjusting screw with the side walls of the recess therein engaging the transversely extending hand pin.
