ML/l, hm f /f CLINTON DE WITT WAGNER, OF CEDAR RAPIDS, IOWA.

DAMPER-CLIP.

To all lwho/ni it Imay concern:

Be it known that fl, Ciiix'rox Dr. 'i'r'r 7i-winnie a citizen of the YUnited States. residing at Cedar Rapids, in the county of Linn and State of lovi, have invented certain new and useful improvements in le)amper-Clips; and Vl 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 to malte and use the same.

My invention relates to new and use'ful improvements in att-aclnnents for stoves, 'furnaces and the like, and especially to that class designated as dampers which are adapted to operate in pipes.

Ity has for its object to provide a simple, inexpensive mechanism which may be readily secured to a pipe in a very simple manner.

A 'further object is to provide an article of manufacture which when constructed will consist of a sheet of thin metal to which is attached a turningrgl mechanism formed of strands of twisted wire.

Roter-ring` to the drawings which form a part of these specifications, Figure l is a vertical, longitudinal sectional view. Fig. 2 is a horizontal sectional view taken on the line 2 2 in Fig. ll. Fig. 3 is a horizontal sectional view taken on the line 33 in l `ig. i. Fig 4 is a detailed plan view o'tl a device used for anchoring one end of the damper to a pipe.

Referring to the drawings in which similar reference numerals designate corre- Specificatoxi of Letters Patent.

Application ied June 15, 1909.

s )ondine )arts throughout the several views, g

a rs 1 is a pipe of any7 preferred dimensions eonl nectmg with a tnrnace or stove, not shown I here for convenience. in which is an opening 2, through which may be inserted a portion of my damper clip which consists ot strands of any preferret'l metallic wire, which bcfore they are inserted in the pipe, the wires are bentin their length at o so that the bent portions ai'e superimposed upon the main portion otl the wire. vle't'ore bending the handle portions 3 and -t at 5 away from each other and at right angles to the main portions ot' the wire, a washer 1.1i and a spring ,t5 are pntupon the main strands after they have been looped. The various main portions of the strands of wire are twisted upon each other to form loops 7, the combination of these loops making a' solid, rigid strand ot' wire. These loops are continued to a point below the handle portion which will fatciited Jan. 25, 1910.

Serial No. 502.272.

cari'y the looped portion within the opening "2 of the pipe i, at which point the strands of wire have a substantially U shaped strand of wire 9 inserted so as to form a catch and shoulders for the damper t), in which is cut a notch Yfor the purpose of permitting the U shaped member to engage theI damper. The U shaped member is inserted between the looped portion so that; its closed end is away from and below the handlel portion, said U shaped member heilig' bent upwardly and outwardly on the line of the looped portion tio form the compound curved portions which engage the damper t). ln order to secure a more rigid structure any preferred loop ot metal, snch as is disclosed by the structure shown at l0, may be twisted around the portion of the looped section which engages the compound curved catch members 8. Below the closed end of the catch members` S the looped portions o t the damper clip are continued as in the looped portions above where the V shaped member is engaged by the looped portions in their length. this lower looped portion Vt1 terminates preferably at a line which may be designated as a horizontal diameter of the damper. 'lhe looped portions extending laterally with the horizontal diameter of the damper in the straight portions '1Q and adapted to enter openings in the damper. thus being bent downwardly to enter said openings, after which they ai'e turned t0- ward each other so as to lform securing lips i?) which are bent so as to rest immediatel)` on the damper.

ln placing my damper with its clip attachment into a pipe, the handle portions 23m-1t as previously described are not. bentA apart as shown in Fig. Q but are superimposed one upon the other and in the same line with the looped portion of the clip. After the handle portions and the looped t portion extending as far as the V shaped member S is inserted tlirongh the opening` Q. a washer let and spring ai'e placed on the looped portion. a'tter which the superimposed portions of the wire are bent away from each other as shown in Fig. '2.

When this damper is used in conjunction with a pipe of large dimensions the various parts of the damper are correspondingly constructed so as to be in proportion, also l utilize a substantially V shaped anchoring device as shown in Fig. et. This consists of two strands ot' wire closed at one end, bent parallel in their length for a certain portion thereof, at which point they are bent outwardly and away from each other and enter into suitable openings where they are bent downwardly against the under face oit the damper to insure a securing means substantially similar to thev lips 13 13 in Fig. 3.

It will be seen from the device described herein that I have provided a damper with a clip attachment which does not require rivets or bolts but one which consists simply of a plurality of twisted wires which may be easily applied or detached, when it is so desired. It will also be seen that T have provided a rigid, substantial structure which is preferably used, although not necessarily so, in pipes that are used in connection with hot air furnaces'and the like.

Vhat I claim is:

1. The herein described device comprising the combination with a pipe having an opening therein anda damper, of an adjusting device cooperating with said damper, said adjusting device comprising a plurality of strands of wire looped one upon the other to form a main portion, one end of said main portion having a handle member, said handle member carrying a yielding member, a washer, said washer adapted to prevent said yielding memberfrom wearing upon said pipe, intermediate parallel spaced apart portions in the length of said main portion, a substantially V shaped member in engagement with said spaced apart portions, a securing portion, a securing member for said spaced apart portion, whereby said V shaped member is held in rigid engagement with said spaced apart portions, straight portions at the terminal of said looped portion, said straight portions extending at right angles to said looped portion and bent downwardly and inwardly in engagement with said. damper.
