JULIUS SCI-IIRRA, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR T0 HAND VACUUM SWEEPER COMPANY, OF PITTSBURGH, PENNSYLVANIA, A'CORLPORATION 0F PENN- SYLVANIA.

Original application filed May 10, 1911,

To all whom it may concern:

Be it known that I, J LIUs SCHIRRA, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Vacuum Cleaning Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in vacuum cleaning apparatus, and has particular relation to the manner of attachment of the suction head to the suction device.

The present application is a division of the application filed by me May 10, 1911, Serial No. 626,274 (patented Nov. 7, 1911, #1008205).

The principal object of my invention is to provide a device of this character in which the suction head is secured to th'forward end of the suction device tire inlet opening for the material being positioned off center of the head,means being provided for removably securing the suction head tothe head of the suction device with proper connections between the suction orifice and the inlet opening.

A further object is. to provide. means whereby the suction head will be operatively connected to the suction device with the inlet into the latter ofi center while the head is supported at a point axially of the suction device.

Other and further objects of the invention are to provide a device of this character which is simple and efiicient in operation,

durable in construction, which may be readily attached to the handle of a household utensil, and which can be manufactured at Specification of Letters Patent.

paratus, of which my invention forms a part. Fig. 2 is a central'longitudinal sectional view of the parts shown in Fig. 1, the suction device being shown as broken away. Fig. 3 is a sectional view illustrating a modified form of suction head connection employed when the structure is applied to a carpet sweeper.

The particular construction of the suction device, shown at the right in Figs. 1 and 2, is not herein specifically described, as it forms the subject-matter of the claims of the application above identified, the only portions thereof which pertain to the present invention being the handle 10 and the plate 13 of. the end cap 12, said plate forming the forward end of the suction device and having the valved inlet and discharge opening the latter communicating with the dust collector 21.

The handle 10 extends axially of the succeive the connection from the suction head,

this inlet being arranged off center, the port being controlled by a valve 19 of suitable type and adapted to operate in accordance with the requirements of use.

The suction head shown in Figs. 1 and 2 is substantially non-flexible, being in the form of a tubular member 29 having its rear end adapted to be passed over the projection 18. and having its forward end secured to or forming a part of the suction head 30, the

latter having a member 31 which is adapted to be passed over the projecting end of the handle 10 and acting aS a continuation .of the handle to support the suction head.

The structure of Fig. 3 is that employed by me in the construction disclosed in my companion application filed February 9, 1911, Serial No. 607,456 (patented Nov. 14,

1911, #1008865), in which the device is shown as in operative relation to and as an attachment for carpet sweepers. In this view the bail of the sweeper is indicated at- 11. the sweeper body being indicated at 1, and being shown as supporting a suction head 2 in ad 'ance of the sweeper body. the suction head being connected to projection 18 by a flexible connection 28. said com1ecticn beingremovably secured to the projection. The ccnnecticn between the sweeper and the lower end of handle 10 is a removable one. so that by disengaging both bail and connectionQS from the suction creating mechanism. the nozzle shown in Fig. 2 can be readily substituted.

The particular structure of parts is such I that either type may be used in connection with the plate 13 and handle 10. \Vhen the device of Fig. 3 is employed. the forward end of the handle is threaded into the bail of the sweeper or secured in a socket carried by such bail. and the connection between the head and the inlet port is mounted on the projection 18. the suction head itself being carried by the sweeper. In the construction shown in Figs. 1 and 2. the head and support are non-flexible and are also connected to the same two parts of the plate. viz.. the handle and the projection 18. In either form the construction is such that the handle through the extension thereof provided by the member 31 or the bail of the sweeper. in effect extends substantially to the suction head so that the handle acts to provide the necessary movements to the head. relieving the conduit connection between the head and the suction device from the pressures produced by such movements. thereby permitting of the use of flexible or non-flexible conduit connections between the suction head or nozzle and the suction device at will according to the character of the support employed for the head or nozzle. the conduit connections being relieved from the pressure provided in moving the apparatus about in operation, such pressures being generally central and in a direct line and applied from the handle to the head or nozzle through the supporting connection therebetween, such latter connection being sufficiently rigid to provide for this application of the pressures.

As will be seen, the arrangement herein disclosed provides substantially two general elements, one being the carpet sweeper for providing a sweeping action. the other being means for creating and applying suction cleaning action. the latter including the two types of suction head and connections. \Vhen the parts are connected as shown in Fig. 3, the suction-creating mechanism acts to provide the to and fro movements to the sweeper, it being understood that the handle 10 forms a portion of such mechanism, in

which case the combined or separate movements of the sweeper and suction-cleaner may be had as set forth in my said prior Patent No. 1.008.865. ()wing to the fact. however. that the suction-creating mechanism is removed from the sweeper as a unit. and the connection 28 detachable from the suction-creating mechanism. it will be obvious that the employment of the nozzle structure of Fig. l. will enable suctioncleaning action to take place separate from the sweeper. thus enabling cleaning action to take place at points inaccessible to the sweeper itself. as for instance. on stairways. etc. This result is due to the ability to separate the sweeper and suction-creating mechanism and the detachability of the suction head or nozzle from the suction-creating mechanism.

'hile I have herein disclosed several ways in which my invention may be carried into effect. I am aware that changes and modifications therein may be necessary to meet the various exigencies of use. and I reserve the right to make any and all such changes and modifications as may be found necessary in-sofar as they may fall within the spirit and scope of. the invention as hereinafter pointed out in the claims.

Having thus described my invention. what I claim as new is 1. In combination. suction-creating mechanism. a carpet sweeper. and a suction nozzle. said nozzle being positioned in advance of the sweeper bod and having a removable connection with said mechanism. said mechanism and sweeper being detachably connected together. whereby said parts may travel as an entirety in the to and fro movements of the sweeper. said mechanism extending above the sweeper and being detachable bodily from the nozzle and sweeper.

2. In combination. a carpet sweeper. a suction-creating mechanism detachabl y connected to and movable with the sweeper body during the to and fro movements thereof, and a suction nozzle in advance of the sweeper body. said mechanism having means above the plane of the top of the.

sweeper body for detachably connecting the nozzle thereto.

3. In combination. a carpet sweeper, suction-creating mechanism removably connected to and positionable to extend over the sweeper, said mechanism having means whereby a dust-inlet nozzle may be removably connected thereto to complete a suctioncleaning device.

In testimony whereof I affix my signature in the presence of two witnesses.
