UNITED STATES JOHN S. THURMAN, OF ST. LOUIS, MISSOURI.
`C'AiPET--RENOVATO R.
SPECIFICATION forming Of Letters :Patent NG. 716,312, dated December 16, 1902.
` Application filed February 24, 1902. Serial No. 95,362. (No model.)
To a/Z whom it. may concern:
Be it known that I, JOHN S.-.THURMAN, a citizen of the United States, residing at the city of St. Louis, Stateof .MissourL have in-V vented a certain new and usefulImprovement in Carpet-Renovators, of which the following is a full, clear, and exact description, 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, forming part of this specification, in which- Figure lis a vertical sectional view through my improved carpet-renovator. Fig. 2 is a bottom plan view of the construction shown in Fig. 1. Fig. 3 is a detail sectional view on line 3 3, Fig. I; and Fig. 4 is abottom plan view of a modified form. Fig. 5 is a sectional view on line 5 5, Fig. 4.
This invention relates to a new and useful improvement' in carpet-renovators, the object being to construct the device ina simple and compact manner, so that the cost of manufacture of devices ofthis character will be lessened and at the same time an efticient and durable construction produced.
With these objects in view my invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.
In the drawings, l indicates a casing, which may be described as being box-shaped and open at its top and bottom. In Fig. l I have shown this casing as being substantially rectangularin cross-section, while in Fig. 4 I have shownthe same as being circular in cross-section. Where the device is rectangular in` cross-section, one or two partitionwalls 2 are provided, said partition-walls extending transversely the interior of the casing and having their upper edges terminating below the upper edge of the casing proper.` Where the casing `is cylindrical in cross-section, as Ashown in Fig. 4, this inner dust-receiving chamber, as it is termed, is formed by a cylinder which is open at its upper end. In the construction shown :in Fig. l a bottom wall 3 is provided, which extends between the partition-walls, said bottom wall having obliquely-arranged lips 4. These lips form flaring ilanges,which extend across the bottom of the casing and lie substantially under the transverse `walls 2. In the circular form shown in Fig. 4 a flange 4a may be formed ilaring and circular.
5 indicates a plate which is provided with beveled edges coperating with the flaring flanges 4, above which beveled edges are recesses 6, forming a continuous supply-passage for the air under pressure, `which is emitted through the slot or slots between the beveled edges of said plate and said lips 4. This plate is adjustably mounted in any suitable manner; but I have shown a'threaded projection 7,which extends upwardly through the bottom wall of the dust-chamber, said threaded projection receiving a nut 8, by which the plate is clamped in position on the under side of the bottom wall. To adjust the plate vertically, and consequently regulate the distance between the beveled edges thereof and the lips 4, I arrange a washer or washers 9 between the plate and the bottom wall, as will be well understood. In the construction shown in Fig. l, where the plate is rectangular in shape, its front and back edges are beveled, while the side edges, as shown in Fig. 3, fit snugly against the side walls of the casing; but the recess 6 uis extended along the sides to conduct the air under pressure to both nozzle-openings. In the construction shown in Fig. 4, where the lip-ange 4a is circular, the plate 5fL is likewise circular and is conical in shape, so as to form a continuous circular nozzle opening. A recess corresponding in all respects to the recess 6 (shown in Fig. 3) is provided around the upper edge of the plate 5a, (shown in Fig. 4,) and this plate'zL may be adjusted vertically by the insertion or removal of washers, as referred to in connection with the description of the corresponding part shown in Fig. 1. The air emitted from between the lips 4 and the beveled edges ofthe plate 5 is directed downwardly and outwardly into and through the article to `be cleaned and the dislodged dirt and dust forced upwardly through passages 11, formed between the walls of the dust-chamber and the casing. Valves l2 are provided at the upper ends of these passages, which valves force the dustladen air inwardly and downwardly into the dust-chamber, so that the heavier particles of dust are deposited therein, while the lighter ICO particles, which are capable of floating off with the released air, pass into a dust-arresting bag, (indicated by dotted line 14 in Fig. 1,) where said lighter particles of dust are arrested on the inner face of said bag, the air thus relieved escaping through the meshes of the bag.
The air under pressure which is supplied to my improved renovator is preferably introduced through a handle 15, said handle being mounted in a hollow boss 16, extending rearwardly from the back wall of the casing. The passage in this boss connects with the space 6, and the air is thus supplied to the nozzle-opening.
The lower edge of the casing is formed with an outwardly-extending flange, and where the casing is rectangular I extend the side walls thereof rearwardly, so as to form runners, as shown in Figs. l and 2; but where the casing is circular the bottom flange is extended rearwardly for the same purpose.
In companion applications filed February 24, 1902, Serial Nos. 95,363 and 95,364, I have claimed other forms of adjustable elements which coperate with an obliquely-disposed lip for regulating the size of the blast-opening therebetween.
Iam aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a device of the character described, the combination with a casing formed with a dust-chamber, of a lip extending downwardly from said dust-chamber, a plate formed with a beveled edge coperating with said lip, and means for adjusting said plate vertically to regulate the size of the opening between the lip and the beveled edge; substantially as described.
2. In a device of the character described, the combination with a casing provided with two partition walls connected together at their lower ends to form a dust-receiving chamber, of obliquely-arranged lips extending transversely and downwardly from said bottom Wall, a plate having its front and back edges beveled or inclined to coperate with said lips, means for adjusting said plate vertically, and a duct or passage for connecting the spaces or chambers adjacent said lips; substantially as described.
3. In a device of the character described, the combination with a casing formed with transverse partition-walls terminating short of the upper edges thereof and forming passages for the dust-laden air, of valves at the upper ends of said passages, a bottom wall connecting said transverse partition-walls, obliquely arranged lips extending downwardly from said bottom wall, a plate having its front and back edges beveled or inclined to coperate with said lips, said plate having a marginal recess in its upper edge and fitting snugly against the side walls of the casing, a duct or passage forair under pressure and communicating with said recess, and a supply-pipe leading from a source of pressure-supply to said duct or passage; substantially as described.
In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 22d day of February, 1902.
JNO. S. THURMAN.
