WALLACE T. MUNGER, OF BRANFO'RD,v CONNECTICUT, ASSIG-NOR TO THOMAS KENNEDY, OF SAMEPLACE.

Letters .Patent No. 62,967, dated March 19, 1867.

IMPROVEMENT IN ATTAGHING DOOR KNOBS TO THEIR SHANKS.

TO ALL WHOM'IT MAY CONCERN:v

I Beit known that I, WALLACE T. MUNGER, of Branford, in the county of New Haven, and State of Connecticut, have invented a new Apparatus for Filling Knobs; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference markedtbereon, to be a full,

clear, and exact description of the same, and which said drawings constitute part of this specification,and represent, in

Figure'l, a side view; and in vFigure 2, a vertical central section.

My invention relates to an apparatus to facilitate the securing oi metal necks to mineral or similar knobs, and consists in the arrangement of` an apparatus arranged to receive the requisite quantity of filling material, and when so received to discharge the said requisite quantity into the knob, whereby the process is greatly facilitated. l

To enable others skilled in tbe art to construct and use my improvement, I will proceed to describe the same as illustrated in the accompanying drawings.

A is a cylinder, connected by a pipe, B, with the vessel which holds the filling material, whether it be `molten lead, sulphur, plaster, or other material in a plastic state. Into the ysaid cylinder is closely fitted a plug, C, but so as to be turned freely therein by a handle, D, attached thereto. In one side of the said plug is formed a cavity, E, corresponding to the pipe B, and opening through the `lower end of the plug by a channel, a. F is an adjusting spindle, which, by being raised up or down into the cavity E, increases or diminishes thc capacity of the said cavity. The said spindle F has an opening through it and communicating with the cavity, (as denoted in tig. 2,) to permit the escape 4of air from the cavity when the tilling substance is admitted thereto, and also to admit air to the cavity when the contents are discharged. In the lower end oi the cylinder A is lfixed a tube, I, corresponding` in size to the opening in the neck of the knob,'and in position so that when 'the plug C is turned so as to close the pipe B the channel a will open into the said tube, as denoted in red, fig. 2.

To ll a knob by my apparatus, place the neck N into the knob K, as seen in iig. 2, then set the neck on to the tube I, (the said tube being provided with a gauge, L, so that the tube will enter the neck the proper distance,) the pipe B conducting the filling substance into the cavity E, turn `the plug C, (which cuts ofi` the pipe .E,) until the channel a opens into the tube I, the llingl substance then passes into the knob' around ltheineck; lthe knob is then removed for the substance to harden, and another knob placed thereon to be filled in like manner.

Having therefore thus fully described my invention, what I claim as new and useful, and desire to secure lby Letters Patent, -is- A l 1. The combination of the cylinder A and plug C and tube I, constructed and arranged so asto receive and discharge the requisite quantity of lling substance, substantially as herein set forth.

2. In combination with the above, I claim the adjusting spindle F, arranged to gauge the quantity of filling substance, substantially as herein set forth.

W.T. MUNGER.
