srncrrrcarrrolv, forming part of Letters Patent No. 521,959, dated June 26, 1894. t
' 1 Application filed September 5,1393. Serial No. 484.934. (NomodeL) Rock and State of Wisconsin, have invented certain newand usefullmprovements in Stovepipe Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains I 7 removed. This cap or stop is provided with to make and use the same.
' My invention relates to an improvement in stove pipe fasteners, thimbles and ventilating stops or caps, the object being to provide means for fastening the sections of stove pipes together, and further to provide means .for securing the stopv or' capin the thimble at different positions whereby to close the thimble or make an opening of any size for venti-, lating purposes, without disturbing the soot which collects inside of the thimble, or danger of the stop or cap becoming accidentally displaced.
' With these ends in View my invention consists in certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the In the accompanyingdrawings, Figure l is a sectional view-showing a' section of pipe in place in the thimble. Fig. 2 isasimilar view showing the stop or cap in position, and Fig.
'3 is a view in elevation.
A represents a thimble which fitsinside of the 'pipewall and forms a lining therefor, and B is a section of pipe adapted to be -inserted in the outer end of the thimble after the usual manner of joining pipe sections together. At the outer end of the thimble a dog 1 is pivoted,it being provided with a spur or pin 2 with a sharpened point which is adapted to be driven into the pipe placed in the thimble whereby to hold the pipe in place. A small pocket 3 is formed on the thimble to receive this'dog and 'conceal it. In assembling the parts the dog is pushed back into the pocket until the'pipe sectionhas been inserted into the thimble. Then the dog is swung forward and its pin or spur 2 is driven into the pipe. In this manner a secure fastening is effected. While it is preferable to in that way pry it. out of the pipe.
placed on the pipe section or one might be employed on every pipe section as desired.
0 represents the cap or stop for closing the thimble when the stove pipe is taken down or an. arm-4 which projects inwardlytherefrom at about right angles and which is adapted to enter; and be held in a socket 5 formed in one side of the thimble, byfriction. Heretofore caps for this purpose have usually been provided with spring arms adapted to engage the inner wall of the thimble but the disadvantage of such constructions is that'they are liable to withdraw soot when removed from their place, and also in such constructions it. is practically impossible to'adjust the cap or stop to difierent positions in the thimble for the purpose of ventilation, without rendering them liable to accidental displacement. In the present construction the. arm 4 enters a socket 5 formed in the wall of the thimble and consequently is out of the way of the soot and the frictional contact is suftioient so that the cap is held at any position that it may be placed in to the full extent of the length of the arm and in this manner the air space may be increased or decreased as required so that a cap of this construction operates as a very successful ventilator. When the cap is pushed in to the fullest extentit not only fits the outer end of the thimble nicely, but it also rests fiat against the wall and the head of the dog and the edge 7 of the socket may form abutments for the cap to strike and rest upon. I 7
It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention and hence I do not wish to limit myself to the exact construction herein set forth, but, 7
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A thimble for stove pipes comprising a pipe having a socket formed in the wall thereof, and having a dog pivoted to it, at or near ment for the cap when thelatter is pushed in 10 the outer end thereof, substantiallyas set to the full extent, substantially asset forth. forth.
