WARD LINCOLN, OF ROCK FALLS, ILLINOIS, AS SIGNOR TO EDWIN J. COOHRAN, OF STERLING, ILLINOIS.
CHIMNEY-CAP.
Specification of Letters Patent.
Patented Feb. 11, 1908.
To all whom it may concern:
Be it known that I, WARD LINCOLN, a citizen of the United States, residing at Rock Falls, in the county of VVhiteside and. State of Illinois, have invented certain new and useful Improvements in Chimney-Caps; and I do 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 to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention has reference to chimney caps, and relates more particularly to the means for securing such caps in place on the top of the chimney. In most devices of this class the cap is held in place by means of four pins or legs extending downwardly from the lower face of the cap-plate, into the four corners of the chimney flue. By reason of chimneys being constructed with fines of varying dimensions, it is desirable to have the engaging legs supported by the cap-plate so that their position can be adjusted so as to conform to the change in the size of the fine, and render the device suitable for attachment to the tops of chimneys of varying dimensions. In my invention I provide a novel and simple means whereby said engaging legs may be supported so as to be adjusted laterally, to correspond with an increase in the width of the flue,or longitudinally, to conform to a change in the length of the opening.
In the drawings: Figure 1 is a vertical longitudinal section centrally of the chimney cap and upper part of the chimney upon which it rests. Fig. 2 is a plan view of the chimney-cap with a portion of one end thereof broken away. 3 is a diagrammatic view, showing the plates 4 in adjusted positions.
Similar parts are referred to by similar figures throughout the several views.
1 represents the upper portion of the chimney, 2 the chimney-cap, and 3 the cap-plate. Near the corners of the plate 3, on the lower face of such plate, are secured four small plates 4 4, by means of bolts 5 5 passing upwardly through rectangular slots 6 6 in the plates 4 and perforations in the plate 3. (Not shown.) Integral with each of the plates 4, and. extending downwardly therefrom is a leg 7, located at a point opposite the angle of the slot 6, and on a line which would bisect such angle. At its upper part the cap 2 is provided with a circular rim 8, to which can be attached a pipe ventilator or other device.
In Fig. 2 two of the plates 4 are shown, in position to conform to a flue of smaller size. It will be observed that in this position the bolts 5 pass through the slots 6 at the angles thereof. The legs 7 having been located in the corners of the flue, the bolts 5 are tightened, drawing the plates 4 against the face of the plate'3, holding the legs 7 from movement, such legs thereupon holding the plate and cap in place on the chimney. It will be seen that the slots 6 are so positionedthat one arm of each extends longitudinally of the plate 3 and the other arm of the slot transversely thereof. By this means, if it is desired to use the cap on a chimney having a flue of greater width this can be accomplished by loosening the bolts 5 and moving the plates 4 laterally until the legs 7 come in contact with the side walls of the flue, whereupon the plates 4 are secured in the adjusted position. The new position of the plates 4 is shown in Fig. 3, wherein the broken lines indicate the top of the chimney. In this position the bolts 5 are at the inner ends of the transverse arms of the slots, each of the plates 4 having been moved outwardly a distance corresponding to one-half the increased width of the flue. For example, if the width of the chimney is increased by the width of a brick, or four inches, which is usually the case, the slot-arms are of sufficient length to permit a lateral movement of each plate 4 of two inches. If the increase is in the length of the flue, instead of in the width, the plates 4 are moved longitudinally instead of laterally, the longitudinal arms of the slots permitting such movement.
My device is susceptible of considerable latitude in the matter of form and construction, without departing from the spirit of the 100 invention.
What I claim as my invention, and desire to secure by Letters Patent of the United States, is:
1. A chimney cap, comprising a plurality 105 of legs adapted to engage the corners of the chimney flue, at the top thereof; a plurality of plates 4 integral with said legs, and provided with rectangular slots 6; a cap-plate 3,
provided with a central opening, and sup- 110 porting the plates 4 so as to permit adjustment thereof along the line of said slots; a
rim 8, surrounding said central opening; and a recess between the plate 3 and chimney-top to accommodate the plates 4, substantially as shown and described.
2. In a device of the class named, the combination with a chimney cap 2 and plate 3 thereof, of a plate 4, provided with a rectangular slot 6 aleg 7, fixed to the lower face of the plate 4, at a point opposite the angle of said slot, and. equi-distant from the arms thereof; and a bolt 5, passing through the slot 6, and secured in the plate 3, substantially as and for the purpose mentioned 3. In a device of the class named, the com- 'bination of a plate 4, provided with a rectangular slot 6, one arm of said slot being disposed longitudinally, and the other one thereof transversely of the chimney-cap; a leg 7, fixed to the lower face of said plate, at a point opposite the angle of said slot; and a bolt 5, passing through the slot 6 and adapted to be secured in the cap-plate, substantially as set forth.
In testimony whereof, I afiiX my signature, in presence of two witnesses.
WARD LINCOLN.
