SPECIFICATION forming part of Letters Patent No. 789,598, dated May 9, 1905.

Application iilcd April 1]., 1903. Serial No. 152,216.

To a/ZZ 'LU/1,0711, 'llt may err/warn:

Be it known that l, lDANIEL l). FARRELL, a citizen of the United States, residing at Dayton, in the county of hlontgomery and State of Ohio, have invented new and useful Improvements in Carpet-Beatei's, of which the following' is a specification.

My invention has relation to new and useful improvements in carpet-beating-machines of that character or type embodying in their structure mechanically-operated cleaning devices arranged and constructed to engage and operate upon the surface of a moving' web of fabric for the purpose of removing loose particles of dirt therefrom.

The primary object of the invention is to provide an improved machine of the character mentioned which will eliiciently accomplish the purposes for which it is constructed.

A further object is to provide an improved means for carrying the carpet, which is so constructed that the carpet may be moved into and out of position to be operated upon by .the beaters and which will be readily adjustable for the purpose of carrying webs of carpets of dllferent lengths and for regulating the tension on said web.

ing a part of this specification, and wherein- Figure l is a View in front elevation of a carpet-beating machine constructed in accordance with my invention. Fig. Z is a view in Arear elevation of the carpet-beating machine.

Fig. 3 is a side elevation. Fig. 4f is aview in elevation ofthe opposite side of the machine from that shown in Fig'. Fig. 5 is a top plan view of the machine. Fig. 6 is a section through a portion of the horizontal bar in which the guide-bloclrs for the beater-opern ating rods are arranged, and Fig'. 7 is a detail view of a modified form of reel.

Referring to the drawings, the machine embodying' my invention is shown as supported for operation upon a suitable base-frame or foundation constructed of longitudinal and transverse timbers l 2, suitably united and braced in order to provide a lrm and rigid -base for the machine. On the transverse timbers 2 are provided suitable bearings, in which is journaled a transverse horizontallyTu arranged shaft 3,' upon which are rigidly mounted belt-pulleys fi, 5, and (i, substantially as shown in Fig.

Arranged upon the base-frame of the machine at a distance from each other are vertical standards or posts 7 8, on which are respectively secured bearings 9 l0. lVithin these bearings is rotatably mounted a horizontal shaft ll, which runs parallel with the shaft 3 and upon which are loosely mounted a plurality of sleeves or hubs 12, which are loosely arranged in order that the shaft may have movement independent of said hubs. Each of these hubs is provided with diametrically-arranged radial trip arms or lingers 1,3 la, which are adapted when the hubs are positively connected to the shaft and are rotated thereby to engage the beaters to operate them to beat the carpet, as will be described hereinafter. The hubs l2 just mentioned are spaced apart suitable distances on the shaft ll and are rigidly connected thereto when it is desired to operate the beater by means of clutches l5, which are slidably arranged on said shaft and are provided with proper faces adapted to engage coacting @dutch-.faces formed on the sides of the hubs l2, substantially as shown in Figs. jl, 2, and 5 of the drawings. ',l.`hese clutches l5 are connected to the shaft to always rotate therewith by means of longitudinal ribs lo on said shaft, which are arranged to engage grooves formed on the interior of said clutches. ln order to operate the clutches to be thrown into and out of engagement with the hubs l2, l provide clutchlevers Y1"?, which are fulcrumed on brackets 18, mounted on the standards 7 and 8, which carry the shaft ll.

TOO

Secured at a suitable point above the shaft 11 and the tripping devices carried thereby is arranged a horizontal bar 19, which is rigidly supported upon the standards '7 and 8. rlhis bar 19 is formed on its top side at distances corresponding to the distance at which the tripping devices are spaced with a plurality of recesses 20, in the end walls of which are formed alining seats or bearings 21, in which are journaled trunnions 22, formed integral with the guide-blocks 23, arranged in the said recesses and which have a rocking movement on their trunnions.- These trunnions are held seated in the bearings 21 by means of bearing-blocks 24, seated in said recesses and the ends of which set over the trunnions, said blocks being held rig'idly in position by bolts, as shown in Fig'. 6.

Extending' entirely through the rocking guide-blocks 23 from side to side are transversely-arranged openings 25, within which are disposed longitudinally-sliding rods 26, the front ends of which are securely fastened to the beaters 27, which comprise vertically-extending spring'- members fastened at their lower ends to thev base-frame and carrying at their upper free ends transversely-arranged beating-heads 28, which, as shown, are arranged in lapped relation in order that the material being cleaned will be repeatedly struck at the same point when the machine is in operation.

Upon the rear ends of the sliding' rods 26 are sleeved depending fingers 29, which are slidingly adjustable along said rods and are secured in adjusted position by means of setscrews 30, passing through said lingers and engaging the rods. This adjustment of the fingers 29 provides an eiiicient means for reg'ulating' the force of the blow given by the beaters, since it will be seen that the closer the fingers are moved toward the beaters the farther the rods 26 will be drawn rearwardly by the fingers 13 14 and that the farther the rods are moved the greater will be the force of the blow.

It will be perceived that when the shaft 11 is rotated the oppositely-disposed trip-fingers 13 and 14, carried by the hubs 12 on said shaft, will intermittently engage the fingers 29 on the rods 26, which will slide said rods rearwardly, drawing back the beaters against the force of the springs 27, and that as soon as the continued revolution of the shaft carries the fingers 13 and 14 out of engagement with the fingers 29 the spring' members 27 will throw the beating-heads into contact with the carpet.

The shaft 11, just mentioned, is driven by a power-belt 11, which is arranged on the pulley 4, mounted on the shaft 3, which belt also passes over a pulley 31, arranged on said shaft 11, whereby rotary movement of the shaft 3 imparts a similar movement to the shaft l1. On the shaft ll'is also provided an idle pulley 32, adjacent the pulley 31 and onto which the belt may be shifted when it is desired to throw the beaters out of operation without stopping the entire machine.

In combination with the beaters I employ a carpet-carrying means of novel construction which is arranged to be swung toward and away from the beaters in order that the carpet on said carrying means may be brought into and moved out of position to be acted upon by the beaters. This carrying' means embraces in its structure two vertically-arranged shafts 33 34, which for a distance from their u pper ends downwardly are threaded, as at 35 36, respectively, and on these threaded portions are arranged verticallymovable internally-threaded blocks 37 38, the threads of said blocks operatively engaging' the threads on the shafts. The shafts 33 and 34 are provided at points below their threaded portions with annular recesses 38 and 38, respectively, adapted to receive tongues 38C of sleeves 38l1 and 38e to secure said sleeves in applied position opon the shafts in order that the sleeves may be held against rotation without interfering with the rotation of the shafts 33 and 34. The sleeves are held against rotation by means of a transverse bar 53, the ends of which are rigidly secured to said sleeves, and it also serves to add rigidity and strength to the structure. On each of said sleeves at a point below the threaded portions of the shafts are provided blocks 39 40, similar in structure to the blocks 37 38, said blocks 39 and 40 being rigidly fixed to the sleeves against vertical movement in order that the rotation of said shafts will move the blocks 37 38 toward and away from the blocks 39 40. The'blocks from the point at which they engage the shafts project laterally in opposite directions to provide horizontally-arranged arms, the opposite ends of which are provided with bearings, those in the upper arm being' designated by 41 and 42, in which are journaled the opposite ends of shafts or rollers 43 44, while the lower blocks are provided with bearings 45 46, in which are journaled rollers 47 48, the rollers carried by the respective blocks being so disposed that when the carpet is placed thereon in the form of an endless belt it can be retained in frictional contact with the rollers by rotating the shafts 33 and 34, which will serve by Virtue of the threaded connection thereof with the blocks 37 38 to adjust said blocks vertically and move the rollers carried thereby toward or away from those journaled in the blocks 39 40 to accommodate the length of the carpet.

49 designates a vertical standard supported upon the base-frame and formed at its Lipper terminal with a horizontal laterally-extending arm 50, in the free end of which is a bearing 51, in which is journaled the upper end of the shaft 34, the lower end of which being journaled in a step-bearing 52, so that said IOO IIO

shaft will be held against lateral movement, but be free to rotate. The lower end of the shaft 33 is journaled in a carriage 7 5, which is provided with a caster 76, adapted to travel on a curved track 77, so that by using the shaft 34 as a pivot the entire carpet-carrying means may be swung away from or toward the beaters.

On the lower end of the vertical shaft 34 is a bevel-gear 54, which meshes with a bevelgear 55, mounted on a horizontal shaft 56, journaled in suitable bearings on the baseframe, and which shaft is driven b y a belt (not shown) passing over a pulley 57, rigidly mounted on the shaft 56 and interposed between the idle pulleys 58 59, also mounted on said shaft. An endless power-belt 60 leads from the pulley 6 to the pulley 59, and a twisted belt 61 leads from said pulley 6 to the idle pulley 58. A belt-shifter of any approved construction (not shown) may he employed to shift either of the belts 60 6l onto the pulley 57, according to the direction in which it is desired to rotate the shaft 56.r By rotating the shaft 56 in one direction the bevel-gear 54 on the shaft 34 will be rotated -to turn said shaft and will also rotate the bevel-gear 62 on the shaft 63, one end of which :is journaled in a bearing 64, secured to the lower end of the sleeve 38e, and its other end is `iournaled in a bearing 65, carried by the carriage 75. As the shaft 63 rotates the bevel-gear 66 thereon will also turn, and as this gear lneshes with the bevel-gear 67 on the shaft 33 said shaft will be rotated at the same speed and simultaneously with the shaft 34, thus causing the upper blocks 37 38 to be moved toward or away from the blocks 39 40, which are lixedly mounted on the sleeves.

The shaft 48 extends through the block 40 and is provided at one end with an extension 68, on the extremity of which is located a clutch-face 69, which is adapted to be engaged by the face 70 of a clutch 71, slidably arranged on a shaft 72, which is journaled in bearings formed in the vertical standard 49, said clutch being operated bya lever 7 0, fulcrumed on a bracket 7l on said standard. At a point intermediate its ends the standard 49 is provided vwith a slot 73, through which the vshaft 72 extends and within which is arranged a pulley 74, carried by said shaft 72. This pulley 74 and the shaft 72 are driven by means of a belt 75, which passes over the pulley 74 and over the pulley 5 on the line-shaft 3, as shown in Figs. 3 and 5 of the drawings.

I also provide a track 78, oppositely disposed to the arc of the rack 77, so that a carpet-carrying means may be pivoted tothe opposite side of the beaters from that just mentioned, so that one of said means may be placed in the path of the beaters while the material to be cleaned is being placed on the opposite means.

By reference to Fig. 5 of the drawings it will be seen that the clutch-face 69, carried by the extension 68 on the shaft 48, is out of engagement with the face 7 0 of the clutch 7l on the shaft 72 when the carpet -carrying means is swung to move the carpet out of operative position to be acted upon by the beaters, so that the said shaft 48 will cease to rotate. As soon, however, as the carpet-carrying means is swungl back to bring the carpet in position to be cleaned the clutch-face 69 on the shaft 48 will be brought into position to be engaged by the clutch 7l in order that the shaft 48 may be rotated to move the carpet. This movement of the carpet enables the same to pass before the beaters at a suitable speed, so that all points of the carpet are struck by the beaters. It will be observed that by operating the clutches on the shaft l1 any one of the tripping devices may be thrown out of operative engagement with relation to the beaters.

In Fig. 7 of the drawings I have shown a modified form of the carpet-carrying means in which is employed two blocks 79 on each shaft 33 and 34 and which are provided with suitable bearings in which are journaled two large drums or rollers 8O 8l instead of the rollers 43, 44, 47, and 48 shown in the preferred form of the invention.

It will be seen that as the rods 26 are moved rearwardly by. means of the tripping' devices the guide-blocks 23, through which the rods reciprocate, will rock on their trunnions in order to provide for a freel and easy movement of the rods and prevent undue bending or torsional strain, to which they would be subjected were the guides fixed and immovable.
