LAMP-CHIMNEY HOLDER.

SPECIFICATION forming part of Letters Patent N 0. 737,628, dated September 1, 1903. Application filed May 11, 1903. Serial No. 156,515. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN HOLMES, a subject of the King of Great Britain, residing at Canning, county of Kings, Province of Nova Scotia, Canada, have invented certain new and useful Improvements in Lamp-Chimney Holders; and I do hereby declare that the following is 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.

Myinvention relates to lamp-chimney holders; and my object is to provide a simple device of this kind with an improved arrangement of the springs for retaining the chimney at its base.

One of the objects of the invention is to ar range the holding-springs so that they will apply a pressure upon the chimney-base, which pressure is distributed over a certain appreciable area, in this way increasing the holding force of the springs and lessening the liability of breaking the chimney.

The invention consists in the construction and combination of parts, to be more fully described hereinafter and definitely set forth in the claims.

In the drawings, which fully illustrate my invention, Figure 1 represents in perspective a burner to which my holderhas been applied. Fig. 2 represents this burner substantially in side elevation, a portion of the holding-springs being shown in section, as well as the lower portion of the lamp-chimney, which is shown in position upon the burner. Fig. 3 is a perspective showing a portion of the burner and illustrating a modified form which my holder may take. Fig. 4 is also a perspective showing a portion of the burner and a second modified form which my holder may take.

Throughout the drawings and specification the same numerals of reference indicate like parts.

Referring more particularly to the parts, a represents a burner having a body 2 and l threaded nipple 3, said burner including a peripherally disposed flange or base 4. Around the periphery of the burner there are disposed a pluralityvof springs or holders 5. These springs are preferably of the form shown in Figs. 1 and 2. It should appear to break the same.

that these springs comprise bows 6, which are disposed outwardly and which are formed below into curves or crooks 7, which crooks attach at their extremities in any suitable manner beneath the aforesaid base 4. As indicated, the upper extremities of these springs are formed into outwardly-bent tips or ears 8, to which tips are attached leaf-springs or clips 9. The lower portions 10 of these clips are substantially straight, as indicated, there being a slight bend or knuckle 11 above, beyond which bend they attach to the aforesaid ears 8. When the lamp'chimney is removed from the holder, the clips 9 normally occupy the position in which they are shown in Fig. 1, where it should appear that their lower extremities rest against the periphery of the bowl 12 of the aforesaid burner-body. WVhen the lamp-chimney 13 is applied, its

base 14 is adapted to pass into the space between the clips or leaf-springs 9 in the manner indicated in Fig. 2, and it should appear that the arrangement is such that when the lamp-chimney is applied in the manner indicated the straight portions 10 of the aforesaid clips will lie substantially flat against the sides of the base in the manner illustrated. It will be observed that these clips 9 are so long that they almost touch the base 4 at their lower extremities. It should be understood that the resiliency of the clips or leafsprings 9 is not depended upon solely to produce the holding pressure, as the aforesaid bows 6 also have animportant function in this respect. It should be observed that the peculiar arrangement of the bows and clips tends to enhance the pliable or adaptable character of the holder. The form of the clips or leaf-springs themselves is especially adapted for giving a firm but resilient grasp upon the chimney-base, it being observed that the bend 11 aforesaid has its convex side toward the chimney-base, so that the outward deflection of the lower portions of the clips will tend to increase the force which they exert without at the same time tending It should be stated that the outwardly-bent tips or ears 8 facilitate very much the application of the lamp-chimney, and it should be evident that when the holders 5 are in the position in which they are shown in Fig. 1 when ready to receive the chimney the fact that the lower extremities of the clips rest against the side of the burner operates to maintain the springs in a more open position to receive the chimney,

it being understood that the resiliency of the inner springs 9 ofiers a resistance to the resiliency of the bows 6, so that the bows would not be permitted to move the ears 8 inwardly to as great an extent as would otherwise be the case. In this manner the springs which constitute the holder oppose each other, as it were, when they are not grasping the chimney and assist each other when they are grasping the chimney.

In Fig. 3 a modified form of the holder is shown. In this form it should appear that the clips 15 are formed integrally with the bows 16, the said bows being of substantial width and having an opening 17 formed in the same, the position of which was occupied by the part 15 before its formation. This form comprises an outwardly-bent ear 18, as before.

The form shown in Fig. 4 comprises an outer member or bow 19, which is integral with the tongue 20, the said members being formed together into an ear 21 at the upper edge 22, at which point they connect. The mode of operation of the forms shown in Figs. 3 and 4 is substantially the same as that shown in Figs. 1 and 2, it appearing that the lower extremities of the

members

15 and 20 rest against the periphery of the base in the same manner as before.

The value of the construction described may be said to lie chiefly in the advantageous manner of applying the spring force or pressure to the chimney over a considerable area and also in that feature of the construction by virtue of which the two resilient portions of the springs or holders are made to oppose each other when the chimney is removed, in this way operating to maintain the springs in a more open position and in a position which could not otherwise be attained by the use of an ordinary spring adapted to give an equivalent holding effect.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or post tion without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. In a lamp-chimney holder, in combination, a base, a plurality of resilient members disposed about said base, and adapted to receive the lower portion of a chimney therebetween, said resilient members comprising an outwardly-bowed portion, an inwardly-inclined portion constituting an extension of said bowed portion, said inclined portion having an outwardly-inclined tip, and a leafspring constituting a portion of said tip, and

normally projecting inwardly and downwardly therebelow, said leaf-spring being adapted to lie substantially flat against the outer side of said lower portion of said chimney whereby the lower edge of said chimney may rest upon said base.

2. In a lamp-chimney holder, in combination, a base, a plurality of resilient members disposed about said base, and adapted to receive the lower portion of a chimney therebetween, said resilient members each comprising an outer resilient bowed member having a substantially straight inwardly-inclined upper extension, said extension having an outwardly-turned ear, a leaf-spring constituting a portion of said ear and projecting inwardly and downwardly therefrom, said leaf-spring having a curve adjacent to the lower portion of said ear, the extremity of said ear normally resting against a portion of said base, the body of said leaf-spring being adapted to dispose itself substantially flatly upon the outer side of said lower portion of said chimney, whereby the lower edge of said chimney may rest upon said base.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
