Application November 19, 1952, Serial No. y3.2.1,410

18 Claims. (Cl. 198-224) This inventionl is a novel barn gutter cleaner, such as shown in my application for U. S. Letters Patent, Serial No. 58,539,r led November 5, 1948 (now abandoned), and the principal object thereof is to provide a power 4driven cleaner which is of novel construction, said construction being simple and having many parts constructed of plastic such as fiberglass or its equivalent, for the purpose of meeting sanitation requirements.

Another object of the invention is to provide a cleaner oi the above type consisting of a longitudinally movable member disposed at one Side of the gutter, having a series of spaced paddles which are actuated in a novel manner to effect the cleaning of the entire gutter as the movable member is reciprocated.

A further object of the invention is to provide novel means for reciprocating the movable member, said means being of simple and eiiicient construction and being designed to minimize wear.

A still further object of my invention is to provide novel means to slide or actuate one or more paddles into one or more gutters running parallel to each other or disposed at any angle desired.

I will explain the invention with reference to the accompanying drawings, which illustrate several practical embodiments thereof, to enable others familiar with the art to adopt and use the same; and will summarize in the claims the novel features of constructions, and novel combinations of parts, for which protection is desired.

As shown in Fig. 1, the barn iloor A is provided,

in rear of the cattle stalls, with a depressed gutter B in the customary manner. At one end o f the gutter B is a iixed frame l which is sup.- ported above the bottom of gutter B in any desired manner, said frame l having a central depressed portion la (Fig. 3) and being enclosed at each end by caps I b for assembly purposes, the depressed portion la serving as a guide for a slidable bar 2 (Figs. 2, 3, 13 and 14), said bar 2 be* ing movable longitudinally of the gutter B, the same being reciprocated by novel means herein.- tfter set forth.

On the top of slide bar 2 are a series of rollers 3 which may be either tapered or straight, but are shown in Fig. 3 as being tapered, the saine being mounted upon stub shafts d Whichy are secured in bores in any desired manner in slide bar 2, the upper ends of the stub shafts 4 being connected above the rollers 3 by a plate 5 (Figs, 13 and 14) to give rigidity to the stub shafts 4, the rollers 3 freely rotating upon the stub shafts 4, and the plate 5 ending With the first andlast stub shaft d of the series, for the purpose hereinafter set forth. i

Upon the frame l at approximately the center thereof is a box 6 (Figs. l and 3), the side plates of which embrace the sides of frame I at their lower ends, as shown more particularly in Fig. 3, box 6 carrying bearings l at its upper end for `the trunnions of lugs 8 oi 4a pivoted casting 9 which supports a housing l t ier worin gear l! (Fig, 3.)., the Worm gear being mounted upon the upper end of a shaft I2 above the casting 9, and said shaft I2 being journaled at the center of the casting S, as shown in Fig. 3. The worm housing I9 is held by brackets 44 (Fig. 4) secured by pins 44a which pass into the casting 9. Gear II is iixedly mounted by means of key I3 or the like for rotation with the shaft I2. By the above construction the shaft I2 may pivot on a horizontal axis with respect to the walls of box 6. The lower end of shaft I2 carries a sliding bearing I4 engaging an larcuate guide I5 secured within box 6 in any desired manner.

The lower end of the shaft I2 carries a star wheel I6 (Fig. 3) which extends down into the open upper end of frame I and lies'to Yone side or the other of the series of rollers 3 as shown in Fig. 3, so that as shaft l2 is rotated byrotation of the worm gear I I, slide bar 2 will be moved in one direction or the other. Worm gear Ii is driven by means of a worm I1 housed within an offset portion Illa of cover I6 (Fig. l), said worm `i1 being mounted Vupon a shaft I8 and carrying `a sprocket or pulley I3 or the like which is driven by a belt or chain 20 which runs around a sprocket or pulley 2I on the shaft 22 of a power unit 23 that is activated by electricity, air, steam, gasoline or the like, the shaft 22 of the unit rotating constantly in one direction when activated. When the star wheel I6 reaches the roller 3 at either end of the series, the star wheel will pivot around the outer side of such roller and the shaft I2 Vwill swing to bring the star wheel I6 on the other side of the series of rollers 3 and thereby automatically move the slide bar 2 in the opposite direction. By the above construction, a continuous reciprocating motion of the slide bar 2 is effected in a simple, novel manner.

Connected to one end of slide bar 2 is a bar 24 (Fig; 2) extending through the outer'end of frame I, same being slidable therein. Belowthe frame I in the bottom of the trough B is a movable composite casing formed in sections, the same comprisingl a casing 25 of U-shaped cross-section mounted in an outer casing 26 but being slidable therein, the casing 25 being actuated by a bar 21 extending througha block 28 in the end of the casing 26, rods 24 and y2I being connected by a strap 29 secured thereon by bolts and nuts 36 so as to cause the bars 24 and 21 to move in unison. The inner end of bar 21 carries a head 3l which is normally spaced from the block 26 so as t0 permit a dwell between movement of the bar 21 and the casing 26 underconditions hereinafter explained.

The function of the member 25 will be hereinafter explained.

Within the outer casing 26 are a series of spaced members 25 identical with the above mentioned number 25, and between the spaced members 25 are bars 32 within the casing 25 having heads 33on their ends receiving pins 34 which extend through the members 25 and the heads 33 of the bars 32, the said pins 34 being insert- '26 'opposite the centers of each of the members y 25 is provided with a 'rectangular opening across which the opposed halves of a socket 35 (Figs. 1, i7 and 18) are secured by bolts passing through holes therein, the two sections 35 together forming a socket for a cylindrical bearing 35 (Figs. '7 and 8) which is carried at the inner end of each paddle arm 31. On each arm is mounted a paddie (Fig. 12) having an upper flange 33e and having an offset lower portion 38a, in the direction of iiange 38e for the purpose of giving 4a downward pressure to the paddle; the portion being bent at 38h below the ange 36o and being mounted in such manner as to have constant contact with the gutter floor. In Figs. 26 and 2l a modied construction of the paddles is shown in which the paddle has a T-shaped upper end 36x, the lower edge being split as at 33g and the split portion beingV oiset as at 362 in opposite directions to make the paddle operable in both directions'of swing.

By the above construction the paddle arms 31 and the'paddles 38 are free to swing into any of the positions shown in dotted lines in Figs. 1,

, 17 and 18 or any intermediate positions, the

swinging movement of the balls 33 on the inner ends of the paddle arms 31 being limited by pairs of pins mounted in openings 40 (Fig. 5) through the members 25. An alternate construction is shown in Figs. 1'1 and 18 in which spaced pairs of ribs 4I replace the pins and embrace the heads For wearing purposes for gutters made of other material than concrete a shoe 45 is provided on the bottom of the casing 26 to give longer wear (Fig. 19).

As shown in Figs. 1, 17 and 18 the outer casing 26 is provided with a series of pins 42 which extend downwardly into slots 43 in the top and bottom of the members 25 so that the

members

25 and 32 may have a limited movement Within the outer member 26 for the purpose hereinafter described. The outer member also carries coupling bearings 26d for the purpose of connecting one section to another, also for strengthening the rods 32 preventing same from buckling.

By the above construction, as the

members

25 and 26 are shifted by the rod 21 the outer casing 26 will move in both directions the full length of rack 2. While initially starting from either end, the inner member is moved an amount equal to the extent of slots 43 (Figs. 5, 1'1, and 18) or the distance between the head 3I and the bearing block 28 (Fig. 2). This initial movement of the

members

25 and 32 which are connected together is for the purpose of first openingor closing the paddles before the paddles are moved longitudinally of the trough.

)It is obvious that in Fig. 1 the paddles shown in full lines are in their mid positions, the pins 42 being shown centrally of the slots 43. If the

assembly

25, 26 and 32 (Figs. 11 and 18) is moved to the right in Fig. 1, the pins 42 will engage the left-hand end of the slots 43, this movement being permitted by the space between the head 3I and the bearing block 28. When reaching such position, the heads 38 on arms 31 will have engaged the left-hand pin in hole 40 of member 25 and will initially shift the paddle into the position in which it is disposed transversely of the trench, as shown in dotted lines in Fig. l before the casing 26 itself starts to move towards the right. Thus, the paddle 38 will be in the proper scraping position before the casing 26 is `actually moved to the right. When the star wheel reaches the opposite 'end of the rack teeth and rolls around said end, rod 24 will then start shifting asomo@ to the left before the member 26 starts to move. Thus, the bladesY 38 will be shifted into position substantially parallel' with the gutter, as shown in dotted lines in Fig. 1, before the member 2'6 starts to shift to the left. Thus, the entire system of paddles initially is projectedv transversely of the gutter and simultaneously shifted substantially parallel with the gutter between 'each move.- ment of the rod 24 to scrape the refuse along the gutter, by a series of intermittent steps, from one end of theV gutter to the other. y
