While this latter connection may be of any approved form of construction, I prefer that seen best in Flgs. 1 and 7, as the same permits of ready application ordet-ac'hm'ent when desired! I In the presentin stance I have shown this connection ascomprising a plate 36 secured to the back face of theseat portion in any suitable manner, this plate having the lugs 37 between whlch other end being guided in a lug 38 projecting from the plate 36, as seen clearly in Fig. 7, the outer end of thebolt having a header the like 39, a spring 40 surrounding the bolt between the lug 38 and the adjacent lug37 and bearing against a collar or the like 41 on a sleeve 42 secured to the bolt in any suitable manner, as by a pin This spring serves to keep the bolt normally projected, so as to hold the link 34 in place, but

when pulledendwise against the spring, the link may be removed. The sleeve serves, by abutting against the lug 38, to prevent entire removalof the bolt.- It will readily be seen that this provides an easy means for attaching or detaching the link 34 and while this isevident that other means may be providedforms a. convenient mode of. attachment, it

for this purpose. While thel'ower. end of the link 31' may be pivotally mounted in any suitable manner, I

find the construction shown in Fig. 6 to be desirable. As hereshown, 44 is a plate secured to the base portion of the. chair and I having the vertical lugs 45 in one of which is a pointed projection 46 engaging a corresponding depression in the end of the link 31, while in the other lug is screw threaded a screw 47 havinga pointed end 48 ensome suitable reticulated material which will permit of the passage of the air therethrough but which will retain the dust and dirt.

I This dust bag is removably held within the cylinderin some convenient manner. In the present instance I have shown. it as having a flange 52 which rests upon the dust cap 53 which is cast to fit the curvature of the cylinder, -54 being a ring on the interior of the cylinder, 55 being the cover which bears against the flange 52 of the dust cap and secured in position by suitable means so that it may be readily detached when desired. In the present instance I have shown the dust cover 55 as provided with oppositely disposed lugs 56 having oppositely arranged openings 57, forming hooks or the'like which engage the bolts 58 which are secured to the cylinder and providedwith thumb nuts 59,

so that when the hooked lugs 56 are engaged .with the-bolts 58 and the-thumb nuts 59 tightened, a perfect air-tight joint is pro-' vided. Loosening of the nuts and partial revolution of the dust cover so as to disengage the lugs from the .bolts, perm1ts of removal offthe dust cover. and then the bag tion with a va'cuum cleaner head of any suit-- able form of constructiom 61 1s a pipe with a suitable coupling 62 so I it can be readily disconnected, one branch of this pipe communicating with the interior of the cylinder 8-, as shownat 63, and the other communicating, as at 64, withthe interior of the how] .17.

said pipe. r

67 is .a spring-actuated valve such as apuppet valve, seen best in Figs. 3 and 4, conone sideJof the diaphragm therein, while 68 is a similar. valve controlling the outlet from 65vis a flap valve pivotal'ly mounted, as at 66, and controlling the communication at 64 between the bowl and the trolling the outlet from the bowl 17 upon the seat is rocked, assuming the parts to be in the positionin which they are'seen in Fig. 2,: downward pressure upon the seat in the direction of the arrow seen in Fig. 2, forces the diaphragm 13 inthe direction of the arrow seen in said Fig. 2. This closes the valve 19 and opens the valve 68 and the valve 65, creating a vacuum in the cylinder 8. As the seat is moved in the opposite direction, the diaphragm is moved in the reverse direction, opening the valve 19 and the valve 67, closing the valve 65 and the valve 68. The alternate movements of the seat causes, by'means of the suction, the dust and dirt from the floor or other surface to be cleaned to be drawn into the dust bag 51. It is to be understood that the alternate opposite movements of the diaphragm automatically controls the valves and, consequently, the suction, so that as long as the chair is being rocked, the vacuum cleaner will be actuated. As nothing is claimed as new in the vacuum cleaner itself and as any suitable form may be employed and connected with the pipe 60 leading to the dust bag, it has not been deemed necessary to illustrate such cleaner.

From the above it will be seen that I have devised a simple, eflicient and durable form of operating means for a vacuum cleaner de-.

signed to be actuated by the movement of a rocking chair, and while the structural embodiment of the invention as herein disclosed is what I at the present time consider preferable, it is evident that the same issubject to changes, variations and modifications in details, proportions of parts etc., without departing from the spirit of the invention or sacrificing any of its advantages. I, therefore, do not intend to restrict myself to the- 1. A rocker, a cylinder supported beneath: the seat portion thereof, a bowl within the cylinder, a diaphragm in the bowl, a rod connected with the diaphragm, pivoted link connections between, the seat and base portions of the chair, apivotal connection between said rod and'one of said links, a connection between the cylinder and bowl upon one side of the diaphragm, and a valved connection between the bowl and cylinder upon the opposite side of the diaphragm.

2;), rocker, a cylinder supported beneath the seat portion thereof, a bowl within the cylinder, a diaphragm in the bowl, a rod connected with the diaphragm, pivoted link connections between the seat andbase portions of the chair, a pivotal connection between said rod and one of said links, a connection between the cylinder and bowl upon one side of the diaphragm, a valved connection between the bowl and cylinder upon the opposite side of the diaphragm, and valve controlled communications between the atmosphere and the bowl upon opposite sides of the diaphragm.

3. The combination with a rocker and its base, pf a cylinder supported on said base beneath the seat portion, a bowl within the cylinder, a diaphragm in the a rod I p Y connected with said diaphragm and extended rearward from said rocker, pivoted link connections between the rear of" said seat and the rear of said base of the chair,

, a pivotal connection between said rod and one of said links whereby rocking of the seat portion actuates said diaphragm, a connection between the bowl and cylinder upon one side of the diaphragm, a valved connection between the bowl and cylinder upon the opposite side of the diaphragmavalve con-' trolled communications between the atmosphere and the bowl upon opposite sides "of the diaphragm, andmeans for the connection of a vacuum cleaner head with the interior of said cylinder.

, 4. The combination with a rocker and its base, of a cylinder supported on said base beneath the seat port-ion, a bowl vwithin the cylinder, a diaphragm in the bowl, a rod connected with said diaphragm and extended rearward from said rocker, pivoted link connections between the rear'of said seat and the rear-of said base of the chair,

a pivotal connection between said rod and one of said links whereby rocking of the seat portion actuates said diaphragm, a connection between the bowl and cylinder upon one side of the diaphragm, a valved connection. between the bowl and cylinder upon the opposite side of the diaphragm, valve controlled communications between-the atmosphere and the bowl upon opposite sides of the diaphragm, means for the connection of-a vacuum cleaner head with the interior of said cylinder, and an automatically actuated outwardly closing valve pivotally mounted within said bowl for controlling the connection between the same and the cylinder.
