"Application-filed November 10, 1921. Serial 1E0, 514,351.

To aZZ whom it may concern Be it known that I, AN'roNIo PA RELLA,

a citizen of the United States, residing at VVaslnngton, 1n the District of -C0lumb1a, have invented certain new and useful Imiprovements' in Insect Guards, of which the following isa specification.

This invention relates to an improvement JIl insect guards andlhas partieularrreference to such a device adapted to be used in.

conjunction with the leg'of an'article of furniture, such as a bed, table or other article thatit is desired to protect.

An object of the invention is to provide such a device which maybe applied to the leg of a piece of furniture without the ne'- cessity of making alterations thereon, and which will present a neat appearance.

A further object of the invention is to provide an article of manufacture'of the above mentioned character which is so designed as to be used'in conjunction with a well known caster now upon the market.

A still further object of the invention is to provide such a guard, which is so con structed, that when the furniture is given a sudden movement, the liquid contained therein will be prevented from overflowing the sides thereof.

A still further object of the invention is to provide such a device which-is extremely simple in construction, strong, durable and highly convenient in use.

Other important objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings,

Figure 1 is a perspective view of the lower end of a leg of furniture illustrating the invention applied thereto,

Figure 2 is a side elevation thereof,

Figure 3 is a plan view of the guard, and

Figure 4 is a transverse section through the guard, showing the caster in elevation. Referring to the'drawings in detail, the numeral 5 designates a leg of furniture, in this instance beingthe leg of a bed.

The guard is formed in acup shape, having a raised central portion 6 and a cup or bowl 7. The central portion 6 extends substantially above the edge of the cup 7 The edge of the cup 7 is turned slightly in as shown at 8. The central portion 6 is provided with an aperture 9 in the centerthereof, for the reception of a stem 10. carried by a caster 11. The casterin this instance is shown as a balltcaster, having a cylindrical body portion 12 and aball bearing 13. The caster-construction iscominon to a well known make .now upon the market. The stem lOjafterpassing through the aperture 9, enters the usual socket in the leg of the furniture. The body portion 12- when engaged, with; the guard, fits, snugly within the central'portio'n 6, andsuchfitis suiticiently tight, to prevent. the caster from. .drOpp ngout. should the furniturebe lifted.

When it isfdesired touse this guard upon the legs of other pieces of furniture, such as an ice box, that is not provided with roll v er means, such guard is secured to the leg by means of screws, passing through opening- 14 formed in the top of the portion 6 of the guard. V I

In operation, when it is desired to place the guard upon a leg of an article of furniture, the caster is forced into the central portion 6, with its stem 10 projecting above the guard. As before mentioned, this fit should be a snug one, and one that requires a small amount of pressure to assemble. The stem is then inserted into the usual socketin the leg, provided for this purpose. Any suitable means may be employed to hold the stem in the socket of the furniture, as this is common practice, and applicant makes no claim thereto. Afterthe guard has been placed upon the leg, same is filled to about the point indicated with some insecticide. Should the bed be given a sudden movement, the liquid contained in the cup will beprevented from splashing by coming into contact with the inturned edge 8, which sets up a backwash in the direction of the central portion and as the portion 6 extends above the cup 7 the liquid will be prevented from coming in contactwith the leg of the furniture. i

veniently applied to furniture and at the same time use a caster now manufactured and. for sale upon the market ice The guard as described is adapted to be,

stamped or pressed from a single piece of metahthereby making its manufacture extremelycheap, and it is highly important that a caster of the type shown be used, as

' it iswell known that the roller casters now in use are very destructive to a carpet or.

floor. lhe ball bearing caster shown has proven itself satisfactory and is more preferable than the roller.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred form thereof,

but is to be understood that various changes in the shape, size and arrangement of parts may be, resorted to Without departing from the spirit of the invention or the scope of the subjoined claim.

Havingdescribed my invention, What I claim is:

7 In an insect guard for the legs of articles of furniture, the combination With an element of stamped sheet metal comprising a cup shape portion for holding an in-V secticide and a centrally disposed portion of inverted cupshape with an opening in its 20 top, said inverted cup shaped portion extending substantially above the upper edge of the first named cup shaped portion,

of a caster comprising a rotative ball and a cylindrical body portion within which said ball is housed and rotates, the external surface of the cylindrical body portion cor responding both as to size and shape to the internal surface of the inverted cup shaped ANTONIO PARRELLA.
