SAW CLAMP.

Application fi1(.l October This invention relates to holding devices, and more particularly to a saw vise.

One of the main objects of the invention is to provide a saw vise of simple construction which, when not in use, can be readily disassembled and folded so as to occupy a minimum of space, this Vise being particularly well adapted for use by carpenters and other tradesmen. A further object is to provide a saw vise which can be readily applied to a vertically disposed support. Further objects will appear from the detailed description.

In the drawings:

Fig. l is a side view of the vise as used.

Fig. 2 is an end view.

Fig. 3 is a section taken substantially on line 3-3 of Fig. 1.

Fig. 4 is a section taken substantially on line 4-4 of Fig. 1.

Fig. 5 is a perspective detail of one oi the vise jaws.

Fig. 6 is a perspective detail of one of the pressure applying bars and the pressure screw and guide rods associated therewith.

F211. is a detail ou one pair of ari'ns of one of the supporting members.

T he device includes two supporting structures and means for forcing the same toward each other for tightly gripping between the jaws carried by the structures the blade of the saw. Each supporting structure includes two supporting arms 1 which are hingedly secured together at their lower ends as at 2. Each arm is provided, at its upper end, with an angularly disposed stud 5 which is adapted to lit snugly into a corrcsj'mniling socket 6 formed in a clamping jaw 7, these sockets I being remote from each other and the arms 1 diverging upwardly toward the jaw. Two bars 8 and 9 extend across the respective supporting structures intermediate the ends thereof and one of these bars carries rods 10 each provided at one end with an eye 11 which is pivotally secured by a pin 12 in a slot 18 cut in the end of bar 8 for this purpose. Rods 10 extend through openings provided in bar 9 for this purpose and are slid-' able through the bar. A headed pressure screw 14 is secured through bar 8 and is slidable through an opening 15 provided through bar 9, this screw being disposed centrally of the bars. A wing nut 16 is threaded onto the screw 14 and bears against the outer face of bar 9. The rods 10 are so 2, 1925. Serial No. 60,115.

spaced as to be positioned in'contact with the outer lateral faces of arms 1 when the bars 8 and 9 are so positioned that rods 10 contact with shoulders 17 formed on arms 1 to limit upper movement of the rods.

In using the vise the supporting structures are placed with their lower portions at opposite sides or a suitable support, such as a board 18 which may be secured across a window or door opening, or in any other suitable position, in any suitable manner. The saw blade B is then inserted between jaws T and by threading nut 16 onto screw 14 the jaws are forced toward each other so as to clamp the saw blade and tightlysecure it in position. If desired, though not necessarily, a suitable pressure screw '4 of known construction may be threaded through hollow pivot 3 of one of the hinges 2 to more tightly clamp these pivots against board 18.- The pressure exerted by this screw will also supplement, to a. certain extent, the pressure exerted by screw 14 and nut 16 so as to more tightly grip the saw blade between the jaws 7. This provides a vise of very simple and inexpensive construction which can be readily applied in such a location as to insure the proper light for filing or sharpening the saw blade. When this vise is not in use itcan be readily disassembled by removing the jaws 7 permitting the arms 1 to move inwardly toward eachother about their pivots, after which the bars 8 and 9 and associated parts can be readily slid downwardly off of the arms, the vise in its disassembled condition being readily packed so as to occupy but very little space. This renders it particularly well adapted for use by carpenters and other tradesmen as it can be readily transported in the usual tool kit.

As will be understood, and as suggested herein, changes in construction and arrangements of parts of the invention may be resorted to without departing from the field and scope of the same and I intend to include all such variations, as fall within the scope of the appended claims, in this application in which a preferred form only of my invention is disclosed.

I hat I claim is:

1. A device of the class described including clamping jaws, supporting members pivotally connected together in pairs and having connection with the clamping jaws. means providing said connection between the lit? . and a structure having portions engaging the opposite correspondlng lateral sides of V clamping jaws and the supporting members,

and means for urging the clamping jaws into clamping relation with respect to an article disposed between the clamping jaws,

said means including a clamping member,

.he supporting members and having other portions engaging opposite corresponding 7 movable means; Iittin about the sun ortin i .L b

jstructures intermediate the ends thereof for forcingsaid structures toward each other;

In a-saw clamp, a pair of supporting structures each including a pair or arms hingedly connected at their lOiWQlf ends, jaws removably mountedon the upper ends of the arms: of the respective structures, the 1 arms; diverging toward the jaws, and removable means fitting about the supporting structures: intermediate the ends thereof for forcmg said structures toward each other, said means acting to guide the supporting structures and to hold themein proper relation toeachother. V I

In asaw clamp, a pair of supporting structures each lnfcluding a 1321-11 charms pivoted at their lower'ends adapted for a clamping engagement with a supporting ele;

ment-,. Jaw's removably mounted on the upper 'ends'ot the arms. oftherespective structures,

the arms diverging toward the jaws; andremovable means fitting about the; supporting structures intermediate the ends thereoi for forcin said structures toward each other v said means acting-to guide the supporting structures and to; hold said lower en'dsv in clamping relation ment. 7

5. In a saw clamp, a pair ofsupporting structures each including a pair ot' arms pivotedat their lowerends for clamping'engagement with a supporting element jaws removably mounted on the upper ends of with the supporting elethe arms of -the respective structures, the

arms diverging toward the jaws; bars extending across the arms of the respective structures intermediate; thecnds thereof, guide rods carried by one of the bars and slidable through the other bar, said'I rods extending across the outer lateral faces of the arms, a pressure screw secured. through one of the bars and slidable throughthe other bar, and: a pressure applyingnm threaded on the screw and bearing against the outer face. of said other bar;

6. In a saw clamp, a pair of supporting structures each including a pair or arms.

pivoted at their lower ends for clamping engagement with a supporting element, jaws removably mounted on the upper ends of the arms of the respective structures, .the

arms diverging toward the jaws, bars extending across the arms of the respective structures intermediate 'the' ends thereof, guide rods carried by one of the bars and slidable 'through the-other bar, said rodseX- tending across the outer lateral faces of the arms, a pressure screw secured through one of the bars and slidable through the other bar, apressure. applying nut thre'adedon the screw and bearing against the outer face i said other bar, and a pressure screw t ireaded through one ofthe' pivots to which said arms are pivoted for increasing the clamping relation between the. said end' portions. and the supporting element. 7
