OSCAR OHALLORAN,

OF NEW YORK, N. Y.

CARPET-BEATER.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed July 24,1906- Serial No. 327,491.

To @ZZ whom t may concern.

Beit known that I, OseAn OHALLORAN, a citizen of the United States, and a resident of the city of New York, boroughof Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Carpet-Beaten of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a portable carpet beater, especially adapted to be operated by hand and which is of very simple, durable and economic construction.

A further purpose of the invention is to so construct the device that in operation beater arms of opposing series will be automatically and intermittently raised and permitted to drop under spring control, thus whipping a carpet in the same manner as practiced by hand.

Another purpose of the invention is to provide a means for holding all the beaters out of the way within the body of the device when said device is to be transported or stored away.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical central section taken practically on the line 1-1 of Fig. 2,' Fig. 2 is a front elevation of the improved beater; Fig. 3 is a side elevation thereof; and Fig. 4 is a front elevation of a portion of the cam shaft, a cam thereon and a section through a lift arm in connection with which the cam operates.

The body of the device consists of side pieces 10, a connecting top piece 11 and a ower connecting bar 12, preferably located about centrally between the longitudinal edges of the side pieces, and the said frame may be of any desired length or dimensions.

A shaft 13 is fixed in the side pieces 10, being located at the bottom portion of the body, and said shaft is adapted to carry beaters arranged in two series, a series A and a series A, the beaters of the two series eX- tending from the shaft in opposite directions. Each beater is of the same construction, and consists of a body arm 14 having a straight flat bottom longitudinal edge, and preferably the body arm 14 is thinnest at its outer end, and a shank member 15 which extends up from the inner end of the body arm 14 and connects with a ring member 16. The ring members 16 are loosely mounted on the shaft 13, and the beaters of the two series are alternately placed on the said shaft and their ring members are held suitably spaced by washers 17 or their equivalents.

A second shaft 18 is secured in the side pieces l() of the body at a point above the beater shaft 13, and springs 19 are secured to the shaft 1S, one for each beater. These springs 19 are connected at their lower ends to straps 20, which straps are secured to the rear or inner peripheral surfaces of the ring members 1G of the beaters, as is shown in Fig. l, the straps connecting with the beaters A being at that side of the ring members of the beaters which face in direction of the beaters A, while the straps which connect with the ring members of the beaters A face in direction of the beaters A. A third shaft 21 is also mounted to turn in the said body above the shaft 1S, and the shafts 13, 18 and 21 are in vertical alinement. The shaft 21 is provided at one of its ends with a crank handle 21., whereby the said shaft is turned. A series of cams B is secured upon the shaft 21. These cams correspond. in number to the number of beaters employed, and each cam consists of an. elliptical body 22 and a segmental tongue 23 integral with the body. These cams B are spirally arranged on the shaft 21, so that the point of one cam is slightly in advance of the point of the next. Two other shafts 24 and 25 are employed, and these shafts are xed shafts and extend from one side of the body to the other adjacent to the longitudinal edges of the side piecesof the body and said shafts 24 and 25 are located one at each side of and above the cam shaft 21.

A series of lift arms O and C are loosely mounted at their outer ends on the shafts 24 and 25, the lifting arms O being mounted on the shaft 241 and the lift arms O on the shaft 25; and the arms on one shaft extend between the arms from the opposing shaft, so that the arrangement of the said lift arms is alternate. The arms C are adapted to operate in conjunction with the beaters A, and the arms C operate in. conjunction with the beaters A.

A strap 27 or its equivalent is attached to its upper edge is inclined or beveled, so that the inner end of each of the lift arms O, and

IOO

IIO

the said straps at their lower ends are se- Y cured one to the outer longitudinal edge of the shank 15 of each of the beaters A, and straps 27 a or their equivalents are secured to the outer ends of the lift arms C and to the outerv longitudinal faces of the shank members of the beaters A. In the construction of each of the lift arms a longitudinal opening 26 is made, one end wall of each opening being more or less beveled. The end wall of the opening in arm C adjacent to the pivoted end of the arm is beveled, while the end wall of the opening in the arm C adj acent to its free end is beveled.

When the cam shaft 21 is revolved the hub portion of a cam will engage with the under face of the pivotal portion of the arm above it, and will lift the said arm more or less, and the upward movement of the arm is continued by the engagement of the convexed edge of the tongue of the cam; and as the lift arm operated on is raised through the medium of its attached strap, the beater with which the said strap is connected is likewise raised, and as the beater is rocked in rising its spring 19 is placed under tension; as the arm reaches the opening 26 in the lift arm upon which it has acted it enters the said opening as is shown in Fig. 4, and the arm is then drawn downward by the spring 19, which also forces the body section of the beater violently in engagement with the carpet upon which the machine is placed.

In the operation of this machine, as the shaft 21 is turned the beaters are alternately raised and lowered at opposite sides of the machine and a constant whipping action on the carpet is obtained, which action serves to free the carpet from dust without injury to its texture. Stay strips 2S are normally placed in engagement with the outer faces of the side pieces 10, being temporarily held thereto by set screws 29, which enter suitable apertures 29L in said side pieces. When the device is set up, however, the stay pieces are removed from their vertical position shown in Fig. 3, and are placed transversely of the bottom portions of the side pieces of the body at their bottom edges, and the set screws 29 are then made to enter openings 30 at the lower portion of the side pieces 10. The strips 28 extend beyond opposite longitudinal edges of the body so as to steady the body while the machine is in action. These strips and likewise the lower edge of the body may be provided with casters if so desired.

When the device is not in use the beaters are folded up within the body as shown in Fig. 3, and bars or pins 31 are passed through openings 32 in the side pieces 10 adjacent to their longitudinal edges, crossing the outer faces of the up-lifted beaters and holding said beaters in their upper position, producing a very compact package for transportation and storage.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent,-
