1 Claim.
The present invention relates to a wrench and more particularly to a wrench for altering the angular inclination of the fins of a sheet metal grille.
The primary objects of the instant invention are to provide a device of the character above indicated whereby the angular inclination of the iins of a sheet metal grille may be conveniently and readily altered, either before or after installation of the grille in connection with its duct; to provide such a wrench whose jaws are adjustable lengthwise adapting it for use in altering the angular disposition of sheet metal grille fins of Varying lengths; to provide such a wrench having a stop adapted to engage the grille whereby its sheet metal fins may all be altered from their original angular disposition to a diiferent predetermined angular inclination; and, to pro- Vide such a wrench which is emcient in use and economical in manufacture.
Illustrative embodiments of the invention are shown in the accompanying drawings, wherein:
Figure l is a face or plan View of a sheet metal grille adapted for installation in connection with an air duct and whose angularly inclined ns are stamped therefrom and integrally formed therewith;
Figure 2 is an enlarged sectional view thereof on line 2-2 of Figure 1 and showing one form of Wrench adapted for altering the original anguiar inclination of the grille fins Figure 3 is a perspective View of the wrench per se;
Figure l is another perspective View of a modifled form of wrench;
Figure 5 is a perspective View of a second modied form of wrench whose jaw lengths may be adjustably xed to adapt it for use in connection with grilles having iins of varying lengths;
Figure 6 is an enlarged sectional View on line t-- of Figure 5;
Figure '7 is a fragmentary plan view of the wrench shown in Figure 3 but having a stop xedly secured thereto whereby the ns of the grille may all be altered from their original angular disposition to a different predetermined angular inclination; and
Figure 8 is a View of the wrench shown in Figure 7, partly in section and showing the manner in which it is adapted for use.
Referring then to the drawings wherein like parts of the grille structure and its n altering wrenches are designated by the same numerals in the several views, the rectangular grille Il) formed from stamped sheet metal is provided with a plurality of transversely disposed ns Il, l2, the fins ll being all disposed at substantially the same angular inclination and the ns l2 being al1 disposed at a different angular inclination whereby the air flowing therethrough and from a duct with which the grille is associated is directionally controlled.
The T-shaped wrench i3 shown in Figure 3 having a pair of spaced elongated jaws I4, I5 of a length substantially equal to the length of the fins Il, l2 may be applied to the individual iins in the manner indicated in Figure 2 for altering their original angular disposition to a different angular inclination, either before or after installation of the grille in connection with a duct and for the purpose of directionally altering the flow of air therethrough.
The modified form of wrench I6 shown in Figure 4 is provided with two pairs of oppositely disposed jaws l1, i8 likewise adaptable for application to the individual fins in the manner shown in Figure 2 and since the spaced pairs of its jaws engage the opposite ends of the lengths of a n to which it is applied, the angular inclination of the fin may be conveniently altered thereby.
A second modified form of wrench I9 is shown in Figures 5 and 6 wherein the oppositely disposed pairs of jaws 2t, 2| are longitudinally slidably adjustable by means of the bolt 22 disposed within the slots 23, 2li and its manually turnabl-e wing nut 25 which adjustable wrench is adapted for use in connection with grill-es having fins of varying lengths.
The wrench 26 shown in Figures 7 and 8 is the wrench shown in Figure 3 but provided with the stop 21 adapted to engage the grille fins Il as shown in Figure 8 for altering the original angular disposition of the fins to a different predetermined angular inclination.
It will thus be seen that the wrenches herein shown and described are admirably adapted to alter the original angular disposition of the iins of a grille throughout their entire lengths and without distortion of portions thereof since the entire length of the 1in or substantial portions thereof at its opposite extremities are engaged by the jaws of the wrench.
While but several specic embodiments of the invention have been herein shown and described, it will be understood that certain details of the constructions shown may be altered or omitted without departing from the spirit of this invention as the same is dened by the following claim.
I claim:
A T-shaped wrench Whose leg provides a handle and Whose head comprises a pair of longitudinally slidably adjustable members, each 5 member having a pair of spaced jaws projecting laterally therefrom at its outer end, each pair of jaws being adapted to engage the opposite sides of an integrally formed n of a sheet metal grille and adjacent its opposite extremities for altering the original angular disposition of the iin to a dierent angular inclination.
