CHARLES E. GOOGINS, OF BROOKLYN, NE YORK.

STEAM-BLOWER.

SPECIFICATION forming part of Letters Patent No. 784,488, dated March 7, 1905.

Application filed May 20, 1904;. Serial No. 208,898-

To (all whmn it may concern:

Be it known that 1, CHARLES E. GooeINs, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Steam-Blowers,of which the following is a specification.

My invention relates to steam-blowers for ejecting air or noxious gases from any inclosed space whether for ventilation or for other reasons, and it may be also employed to deliver a strong constant blast of air to furnaces as forced draft or to be directed wherever desired for any special purpose.

Contrivances having the general nature of my invention and falling within the class to which it belongs create a moving current of air by means of one or more steam-jets passing through nipples having usually contracting and expanding mouths, the action of the jet being in part to cause a partial vacuum and consequent inrush of air into the contracting mouth which first receives the jet and to impress a portion of its Velocity upon the air so taken up, the condensation of the steam continuously making room for more air entering the system in the same direction with the jet.

Various combinations of mechanical parts have been constructed for adjusting the jets with respect to the nipples or injector-tubes and for locating those parts with reference to the casing or pipe through which the blast is delivered.

The object of my invention is to provide in 'a steam-blower devices having particular and improved form and arrangement whereby the jets and the nipples are adjustable with regard to each other and to the blast or delivery pipe.

1 accomplish the object stated by fashioning and assembling the parts as illustrated in the accompanying drawings, wherein- Figure 1 represents a longitudinal sectional view of the associated elements. Fig. 2 is a plan view of the crank-ring. Fig. 3 is a plan view of the jet-frame. Fig. 4 represents a cross-section upon the line 0 a of Fig. 1 looking toward the blast-pipe and showing one of Fig. 5 is a vertical secthe locking-plates.

tion, and Fig. 6 a top view, of the clampingnuts which support the nipple-seating plates upon the screw-rods.

Like numbers are used to refer to like parts in all the views.

Each constituent element is described in detail and its individual office, together with the mode of operation of the whole, fully set forth herein.

Considering the drawings, numeral 1 designates a steam-pipe usually furnished with a cut-otf valve 2, an escape-valve 3 for permitting escape of condensed steam when starting the blower, and a third valve 4 to admit steam immediately to the jet-pipes As ordinarily constructed by me the jet-pipes consist of two parallel members and one median transverse member, all formed integrally with a cruciform frame 6. (See Fig. 3.) The parallel members of the jet-pipes have jet-nozzles 7 at their extremities, making four nozzles, and the transverse member of the jet-pipe possesses a nozzle at each end and in the middle, making a total of seven nozzles T. The bores 8 of the nozzles expand slightly toward their mouths, this being found to be the form of jet offering least retardation to the force of the steam. Smooth-bore bosses 9 terminate the arms of the jet-frame 6, and at the middle of the frame is a suitable coupling 10 for the steam-pipe.

Number 11 marks the screw-rods extending lengthwise of the invention and by which the parts are held together and adjusted. Two of the four rods are shown in Fig. 1. Each rod has an integral collar 12 near its upper end and a smooth cylindrical extremity 13, which passes through a boss 9 of the jet-frame and is provided with a crank 14. Three of the cranks let have at their outermost ends the smooth pins 15, provided with threaded ends. The pins 15 pass movably through smooth holes bored at quadrantal points through the crank-rii'ig 16, and nuts 17 engage the threaded ends of the pins and retain the crank-ring. (See Fig. 2.) One of the pins 14 is extended into a handle 18, and as all the cranks are connected by the ring and have the same throw all are turned by means of handle 18. It is thought to be now apparent that when p 22 are taken off the ends of 'the sleeve-nuts,

which are then passed through suitable openings near the edges of the plates 24, whereupon the nuts 22 are again screwed into position and the plates supported between them and the shoulders 20 of the sleeve-nuts. The nuts 19 are freely movable and revolublein the openings of plates 24, through which they pass. It is found to be desirable to lock the clamping nuts after the plates have been placed in position. 1 effect this by constructing the annular lock-plates 25. (See Fig. 4.) The lock-plates are movably held upon the surfaces of the plates 24 by the headed pins or-screws 26 passing through curved slots 27 of the lock-plates into plates 24. To engage the nut-form ends 23 of the sleeve-nuts 19, and thus to prevent the nuts from rotating with respectto plates 24, slots 28 are formed through the lock-plates, having a circumferential direction, and enlarged portions 29, contracting into portions of less width and having parallel sides 30. It will be noted now that if a lock-plate be moved by means of its handle 31, causing the parallel sides 30 of the slots to engage opposite and parallel sides of the tops 23 of nuts 19, the nuts cannot thereafter turn with respect to the lock-plate or nipple-seating plate '24. The remaining ends of the screw-rods 11 pass through the flange 32 of the blast-pipe 33, as shown in Fig. 1, and nuts 34 secure the rods to the flange.

All similar parts are duplicates excepting the nipples or injector-tubes. Considering Fig. 1, the upper nipples 35 (those nearest the nozzles-7) are the smaller in size, while nipples 36 (shown in the lower position) are larger. The first set of nipples directs the jet into the second, and between them the way is open -to entering air, drawn in mechanically by the friction of the jet with surrounding air particles or pressed in to fill the place occupied previously by condensed steam. Air is thus taken up in the stream and. forced forward by the steam through the longer nipples 36 into the blast-pipe 33, having the contracted entrance shown, and by the combined action of its velocity and the further condensation of the steam a strong blast of air is delivered through pipe 33, of which the condensed steam constitutes a small part volumetrically. The nipples are held in the plates 24 by the engagement of relatively enlarged The office of cylindrical portions 37 and shoulders 38 with suitable seats or orifices 39, formed through the plates.

The operation may be described as follows: Vhen the parts have been assembled, as illustrated in Fig. 1,with the clamping-nuts locked and nuts 34 unscrewed, the screw-rods may be turned by handle 18 and ring 16 and all the nipples, both large and small, moved together toward or from the jet-pipes or blastpipe; but if one of the lock-plates is turned, bringing the greater openings 29 of its slots 28 about the ends 23 of the sleeve-nuts, those nuts will turn by reason of frictional engagement with the screw-rods and will not change positions along the rod. The remaining lockplate upon the other nipple-seating plate prevents its set of nuts from turning, and therefore these non-rotating nuts, with plate 24 and nipples borne by it, will be moved toward or from the other set of nipples.

Having thus described my invention and explained the manner of its operation, what I claim is 1. In a steam-blower, the combination with a movable blast-pipe, of a jet-frame and jetpipes provided with nozzles, means for serving steam to said jet-pipes, a movable nippleseating plate, nipples seated upon said plate and supported thereby in alinement with the said nozzles, and adjusting devices whereby the said plate and nipples and the said blastpipe may be adjusted toward or from said nozzles and with respect to each other.

2. In a steam-blower, the combination with a movable blast-pipe, of a jet-frame and jetpipes provided with nozzles, means for serving steam to said jet-pipes, a movable nipple-seating plate, nipples seated upon said plate and supported thereby in alinement with the said nozzles, adjusting devices whereby the said movable plate and nipples and the said movable blast-pipe may be adjusted toward or from said nozzles and with respect to each other, and locking means adapted to place one IIO of said movable elements in and out of engagement withsaid adjusting devices.

3. In asteam-blower, the combination with a blast-pipe, of a jet-frame and jet-pipes provided with nozzles, means for serving steam to said jet-pipes, movable nipple-seating nuts, and movable annular locking rings borne by said plates and havmg slots arranged to engage said tops 23 of the nuts whereby the I 5 revolution of the clamping-nuts is permitted and prevented and said plates adjusted.

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

CHARLES E. GOOGINS.
