A TTOR/Vf Y United States Patent FIRE EXTINGUISHER MOUNTING BRACKET FOR VIBRATION SERVICE Walter M. Haessler, Chatham, N.J., assignor, by mesne assignments, to The Fyr-Fyter Company, Dayton, Ohio, a corporation of Ohio Application May 5, '1953, Serial No. 353,114
3 Claims. (Cl. 248-304) The present invention relates to an improved portable fire extinguisher mounting bracket particularly suitable for vibration service.
A mounting bracket for portable fire extinguishers in common use has an apertured mounting lug extending from the extinguisher valve and adapted to be hung on a wall hook. The fire extinguishers carried by such brackets on vehicles or kept in factories or other places where vibration is present have been found to have their mounting lugs badly worn.
The present invention aims to overcome the difiiculties presented by the prior mounting brackets by providing an improved mounting bracket resistant to wear under vibration service.
Another object of the invention is to provide an im proved mounting bracket which is simple and economical in manufacture, efficient in operation, and durable in use.
In accordance with the invention this is accomplished by providing a mounting bracket incorporating centering means preventing lateral displacement of the mounting lug without a lifting action, thus, a damping effect is provided preventing the lateral movement which causes 7 wear.
Other objects and advantages of the invention will be apparent from the following description and from the accompanying drawings which show, by way of example, an embodiment of the invention.
In the drawings:
Figure 1 is a side view of a portable fire extinguisher in position on a mounting bracket in accordance with the invention.
Figure 2 is a top view of the outwardly extending portion of the mounting bracket.
Figure 3 is a side view corresponding to Figure 2.
Figure 4 is a side view of the mounting bracket including a downwardly extending guideway portion thereof.
Figure 5 is an end view corresponding to Figure 4.
Figure 6 is a top view corresponding to Figure 4.
Referring to the drawings, there is shown a portable fire extinguisher 1 secured in position to a wall 2 by a mounting bracket 3 in accordance with the invention.
The mounting bracket 3 includes a wall member 4 having an outwardly extending portion 5 at the end of which is an upwardly extending pin member 6. The pin member 6 is adapted to be received in an apertured mounting lug 7 extending outwardly from valve 8 of the extinguisher 1. In order to prevent swinging of the extinguisher when carried by the mounting bracket, a downwardly extending side member 10 may be provided having at its lower end outwardly extending clip members 11 and 12.
The wall member 4 may be made of strap metal shaped as illustrated with the outwardly extending portion or extension 5 at approximately right angles to the wall member 4. Reinforcing ribs 14 and 15 may be formed for the stiffening of the shaped bracket. Adjacent the outer end of the extension 5 is an aperture in which is received the pin member 6. The pin member 6 has a 2,910,262 Patented Oct. 27, 1959 ice lower downwardly extending portion of reduced diameter adapted to fit in the aperture of the extension 5, the lower end 16- of the pin member being peened over to secure the pin member in position. The lower portion of the pin member 6 is enlarged and formed with an inclined surface 17 while the main body of the pin member 6 is made with a straight vertically extending wall having its top rounded as indicated at 18 to facilitate the entry of the pin member into the aperture of the mounting lug 7.
In accordance with the invention the inclined surface 17 is made with its upper diameter somewhat smaller than the diameter of the aperture in the mounting lug 7 while its lower diameter is somewhat larger than the diameter of the aperture. The inclined surface 17 is preferably made with an angle of about forty-five degrees with respect to the vertical as this is a convenient angle for machine fabrication. The structure in accordance with the invention is to provide a centering means on the bracket, such as will prevent lateral displacement of the apertured mounting lug unless accompanied by a lifting action. This is accomplished by providing the inclined surface 17 of at least a minimum angular deviation from the vertical to engage with the wall of the aperture in the mounting lug 7. Preferably the wall of the aperture in the mounting lug 7 is formed with a surface of about forty-five degrees deviation from the vertical. However, it is not necessary that the angular surface be provided on the mounting lug 7 as a suitable surface will be worn therein after a short amount of use. It is believed that the work involved in lifting the mounting lug, or tending to lift the mounting lug under vibration service, achieves a damping'effect so that there is no appreciable Wear between the inclined surface 17 and the mounting lug 7. A sufficient angular deviation from the vertical is necessary to prevent a wedge action which might take place if the angle is too small or less than fourteen degrees. The coefficient of friction is expressed as the tangent of the angle of repose for a block on an inclined surface. In the case of steel on steel, the coefiicient is approximately .25 which is approximately the tangent of fourteen degrees. Accordingly, the inclined surface should have an angle greater than fourteen degrees in order to prevent a wedge effect, the forty-five degree angle being preferably used, as stated above, for facility in machining.
The wall member 4 is apertured as indicated at 20 and the side member 10 is apertured as indicated at 21 to receive bolts or screws to secure the bracket in position on the wall. The clip members 11 and 12 may be formed of a single piece of material apertured and secured to the lower end of the side member 10 by rivets 24 and 25. The outer end of the clip members 11 and 12 may be turned outwardly as indicated at 26 and 27 to facilitate the insertion of the container of the extinguisher 1.
While the invention has been described and illustrated with reference to a specific embodiment thereof, it is obvious that other embodiments may be resorted to without departing from the invention. For example, while the pin member 6 has been shown having an enlarged lower portion providing the inclined portion 17, it is obvious that a washer member might be placed over the pin member 6, the surface 17 being provided on the exterior of the washer member. Further, while the pin member 6 has been shown as secured in position by peening over its lower end, as indicated at 16, other structures might be utilized, such as the use of a nut on a threaded lower end of an alternative pin member 6. Another structure might be made by a stamping operation in which the pin member 6 and inclined surface 17 are stamped from the outwardly extending extension 5. Therefore, the form of the invention set out above should be considered as illustrative and not as limiting the scope of the following claims.
I claim:
1. A mounting bracket for vibration service to receive an apertured mounting lug comprising a wall member, an outwardly extending extension for the wall member, the extension being apertured adjacent its outer end, and an upwardly extending pin member secured in position in the apertured extension, the lower portion of the pin member having an inclined centering surface making an angle of at least fourteen degrees with the vertical for support of the apertured mounting lug, the upper portion of the pin member of generally cylindrical shape and having a diameter smaller than the diameter of the inclined portion and smaller than the diameter of the aperture in the mounting lug, the outward end of the pin member rounded to facilitate entry into the apertured mounting lug whereby lateral displacement of the apertured extension produces a lifting action.
2.
