JOHN S. THURMAN, OF ST. LOUIS, MISSOURI.

CARPET-RENOVATOR.

Specicaton of Letters Patent.

Application filed October 23, 1902. Serial No. 128,382.

To ,ZZ whom, it may concern.'

Be it known that I, JOHN S. THURMAN, a

citizen of the United States, residing' at St. Louis, Missouri, have invented a certain new and useful Improvement in Carpet-Renovators, of which the following is a full, clear, and exact description, suoli 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 l is a side elevational view of my improved renovator. Fig. 2 is a rear elevational view of the same. Fig. 3 is a vertical longitudinal sectional view of the same. Fig. 4 is in part a Vertical transverse sectional view on the line 4L L of Fig. 3 and in part a front elevational view of the same, and Fig. is a horizontal longitudinal sectional view of the same.

This invention relates to a new and useful improvement in carpet-renovators, the object being to construct a device of the character described which is capable of effectively renovating a carpet-that is, dislodging the dust and dirt therefrom when being moved in two directions-to wit, forward and backward.

Heretofore renovating-machines known as the double machine have been provided with a simple blast with passages for the dustladen air on both sides thereof, and it is claimed for these machines the virtue of performing eective work when being moved forward and backward. Still other machines have been provided with a circular blast which enables the machines to be moved in any direction. In all of these machines the blastnozzle has been fixed with relation to the casing, and it is obvious that this fixed angle of the blast is most effective when the machine is being moved in the proper direction to take advantage of the angle of the blast.

It is the prime object of my present-invention to provide means in a carpet-renovator whereby when the machine is being moved in one direction the angle of the blast will be such as to most advantageously renovate the carpet and when the machine is being moved in the opposite direction the angle of the blast will be changed so as to most advantageously renovate the carpet under vthe changed conditions. This changing of the angle of the blast I prefer to make dependent upon the direction in which the renovator is being moved, providing means whereby it is automatically accomplished; butit is obvious that the operator can change the angle of the blast without moving the casing over the carpet by simply manipulating the handle.

In the drawings, 1 indicates the casing,which is preferably open at its top and which discharges the dust-laden air into a dust-arrest.- ing bag 2, as has heretofore been done.

3 indicates the side walls, and 4 the bottom wall, of a dust-collecting chamber, which, with the casing l, provides two passages for the dust-laden air on each side of the machine. The chamber in the bottom of the machine, which communicates with these passages, has the adjustable blast-nozzle located therein, as shown. At the upperends of the passages for the dust-laden air are located the valves 5, which are lifted by the dust-laden air and direct said dust-laden air downwardly and inwardly, so as to enable the depositing of the heavier particles of dust in the chamber formed by the walls 3 and 4f. To protect these valves from the accumulation of dust on their upper faces, which would tend to interfere with their proper operation, I provide shelves or extensions 6 thereover, as shown.

7 indicates the blast-nozzle, which extends transversely the machine, which blast-nozzle is provided with a removable side wall 8, secured in position by suitable screws. This removable wall is preferably finished flush on its inner face, so as to fit snugly against the body portion, and in order to provide the slit or opening through which the blast of air issues I provide thin sheets of paper or other material 9 at the side edges and at the rabbeted joint, as has heretofore been described in my former patents. The ends of the nozzle 7 have secured thereto suitable head castings 9, which project through openings in the side walls of the casing. These openings, as shown in Figs. 1 and 4, are elongated, the longest diameter being less than a right angle to the axes of the operating-handle.

10 indicates extensions on the head-castings in the form of rock-arms, to which the yoke members Il of the handle are pivoted. These yoke members extend forwardly from the branches of the handle, which branches are preferably made hollow to provide conduits for the compressed air, which conduits are connected by iiexible pipes l2 to the chambers in the head-castings 9.

In operation it will be seen that when the renovator is pushed forward the handle, being connected below the pivotal point of the noz- Patented. Sept. 26, 1905.

zle, will swing the nozzle on its pivot, the l liexible pipe permitting this, and throw the nozzle forward, so that it comes in contact with the nap of the carpet, bending the same forward to enable the issuing blast ot' air to more readily dislodge the particles of dirt and dust in the carpet, 'forcingI them into the forward passage and up into the chamber in the casing. The lower ends ol the slots in the side walls of the casing act practically as stops; but as the lower end olI the nozzle is ilush with the lower face of the casing, or it may project slightly beneath the lower face oi the casing, it' desired, the end oi' the nozzle may be pressed well down into the nap 0f the carpet to ciIecv tually perform its work. Then the direction ot' movement of the renovator is changed and it is pulled backward, the pressure on the handle will cause the trunnions of the blast-nozzle to ride up in their respective slots, so as to permit the angle of said nozzle to be changed. The long axis of the slot being slightly less than a right angle to the handle will cause the pull on the handle in a horizontal direction to force the end of the nozzle well down into the nap of the carpet, and the dust-laden air will now be forced up into the passage at the back of the machine.

In order that the angle of the blast-nozzle may be adjusted when the machine is being moved in either direction, I provide set-screws 13 in the bottom wall et, which extend thercthrough and cooperate with the blast-nozzle in its diderent positions. rIhese set-screws may be adjusted from the interior, and when the proper angle of the nozzle has been determined fordiiferent kinds ot' work the machine may be operated without further adjustment.

So far as I am aware I am the iirst to pivotally connect a nozzle to the handle of a carpet-renovator, whereby when the renovator is in operation pressure exerted on said handle either in a direction toward the casing or from the casing to move the renovator will change the angle of the nozzle, so as to project the blast ot' air issuing from the nozzle in a forward direction with respect to the movement of the renovator-casing.

I am 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 vfrom 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-
