RECIPROGATING MOP.
Application filed May 12,
This invention relates to improvements in reciprocating mops, and refers more particularly to a reciprocating mop adapted to run up and down a fixed course.
It is an object of the invention to provide a reciprocating mop for such purposes as sweeping bowling alley floors wherein the mop carriage is moved back and forth along its course by an endless chain in one direction.
' Another object of the'invention is to provide a reciprocating mop having supporting arms so mounted on the carriage that they normally project laterally therefrom, are swung forwardly through an are when the carriage reaches the end of its trav el 1n either direction, and reassume a position substantially at right angles to the carriage as the latter commences to move back along its path.
With these and other objects in vlew the invention is hereinafter more fully described with the aid of the accompanying drawings, in which:
Figure 1 illustrates a plan view showing a plurality of bowling alleys equipped with the invention.
Figure 2 is a side view of Figure 1, and
Figure 3 is a section on the line 3--3 of Figure 1.
Figure 4: is a plan view of the carriage showing the mop carrying arms in normal outstretched position.
Figure 5 is a side elevation of the carriage showing one of the mop carrying arms swung forwardly, and the carriage in contact with a stop at one end of the course. I
Figures 6, 7, and 8 are sections on the lines 66, 77 and 8-8 of Figure ,5.
Figure 9 is a detail.
Referring to the drawings, 1 deslgnates bowling alleys having the usual gutters 2 on each side. Between each alternate pair of gutters is a conventional raised ball runway 3. and between each other pair of gutters is a raised course 4 having guide rails 5 thereon to guide thewheels 6 on the underside of the carriages 7. At the ends of the courses 4 head and tail sprockets 8 and 8" are mounted on head and tail shafts 9 and 9 supported by bearings 10 and 10*. The head shaft 9 may be driven from a drive shaft 11 arranged under the floor and said drive shaft may be rotated as by a motor 12. Stops 13 which. project inwardly to- 1927. Serial No. 190,742.
wards one another are provided at each end of the course 4, and driving chains 14 are arranged around each pair of head and tail sprocketsv 8 and 8 I will now proceed to describe one of the carriages 7. Each earriage'consists usually of a lower platform 15 having .downwardly flexed sides 15* which support the outer ends of the axle 16 on which the wheels 6 are mounted, and at the sides of the platform towardseach end distance pieces 17 are secured which in turn support an upper plate 18.
On the underside of the plate 18- towards one end and substantially centrally of its width 9. bearing 19 is secured. 20 indicates a slot in one end of the plate 18. Pivotally mounted in the bearing 19 and projecting upwardly through the slot 20 is a member 21 having an upwardly extending arm 22 and downwardly extending bifurcations 23 the lower ends of which latter are flexed outwardly. the plate 18 a bracket 24 issecure'd, and '25 indicates a coil spring one end of which is secured to the bracket 24 and the opposite end to the arm 22 thereby tending to hold said bifurcations 23 in outstretched position. Guides26 are also secured to the plate 18 and have openings 27 through themthrough which the ends of the slide 28 pass. Intermediately of its length and on both sides of the slide are racks 29. 30 designates a rest secured to both the guides over which the slide is adapted to move. 26 denotes an opening through one of the guides 26' and Towards the opposite end of one end of the rest 30 through which the coil spring 25 passes. 1
Substantially centrally of the length of the carriage 7 two vertical shafts 31 are arranged. The lower ends of the latter are revolvably supported by the platform 15 and their upper ends extend through and are I and these ends are pivotally connected as by pins 37. Projections 46 are mounted on the upper sides of the plate 18 each having one end of. a spring 47 connected to them and the opposite ends of these springs are fastened to the pins 35 so as to tend to hold the arms 36 in laterally outstretched position.
Substantially centrally of the underside of-the platform 15 towards its end remote from the bearing 19 a bearing ,38 is secured substantially centrally of the width of the carriage. 39 indicates a slot at one end of the latform 15. Pivotally mounted in the bearing 38 and projecting upwardly through the slot 39 is a member 40 having upwardly extending arms 41 and downwardly extending bifurcations 42 the lower ends of which latter are outwardly flexed. Towards the opposite end of the platform 15 from the bearing 38 av bracket 43 is secured thereon, and 44 indicates a coil spring one end of which latter is attached to the bracket 43 and the other end to the arm 41 thereby tending to hold the bifurcations in outwardly disposed position.
On the distance pieces 17 adjacent to the bearing 19 inwardly extending guide arms 45 are secured which have downwardly and outwardly curved bearing surfaces which are spaced somewhat wider apart than the width of the chain 14, the up )er length of which passes between them. 11 the raised course 4 adjacent to the tail sprocket 8 is an inclined lifter 48 which raises the lower portion of the chain at that point so that when the carriage is in the position shown in Figure 5 on its course the chain must pass between the b furcations 42 which are spaced somewhat wider apart than the width of the chain.
In 'the chain is one horizontal pin 49 which projects beyond the sides of the chain. As the latter turns the carriage 7 remains stationary until the pin strikes the guide arms 45 which cause it to rise and engage the bifurcations 23. The carriage then travels with the chain in the direction of the arrow A. When one end of the slide 28 strikes a stop 13 the former moves through the guides 26. The racks 29 cause the gears 32 to turn thereby turning the shafts 31 and the mop supporting arms 32 through an arc in the direction in which the carriage is travelling. When the slide 28 has been moved back until one end of its wider central port on 28 strikes one of the guides 26 the stop halts further movement of the carriage. The movement of the chain however continues thereby forcing the bifurcations 23 inwards against the tension of the spring 25 until they are sufficiently turned to release the pin 49. The carriage then remains still until the pin has passed around the tail sprocket 8*, and has been guided by the lifter 48 into engagement with the bifurcations 42 when the carriage is moved back in the direction indicated by the arrow B. When the carriage reaches the opposite end of its travel the slide 28 is moved in the opposite direction in a similar manner and the opposite stop 13 and the pin 49 is released in the same way from the'bifurcations 42. I
As soon as the carriage commences to travel from a stop in the direction opposite to that in which it has last moved the spring 47 which has been stretched by the rotary movement of its pin 35 turns the latter, and its collar 34, shaft 31, supporting arm 36, gear 32, and rack 29 and slide 28 back into mid position; and this movement of the slide also turns the opposite gear, shaft and supporting arm back as well. In this manner the mop supporting arms are brought back into outstretched position and are normally held there by the springs 47 The mop supporting arms 36 are downwardly inclined intermediately of their length as shown at 36, and terminate in substantially horizontal portions 36 which take into housings 50 between the lower sides of which the mops 51 are held. 52 designates set screws for holding the housings on the portions 36 In order to sweep the gutters 2, gutter mops 53 are loosely connected to the ends of the mops 51 as by means of links 54 shown in Figure 9.
It will be noted that when desired either mop supporting arm may be swung into an upward position as shown in Figure 3 when it is necessary or desirable to sweep only one alley.
lVhile in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that the construct on is susceptible to such modifications as fall within the scope of the appended claims.
