Application filed April 6,
To a-ZZ whom t may concern: Y
Be it known that I, FRANCIS MCMURDIE, a citizen of the United States, residing at the city and county of Kalamazoo Iand State of Michigan, have invented certain new and useful Improvements in Blast-Gates, of which the following is a specification.
This invention relates to improvements in blast gates.
rIhe objects of the invention yare to provide a simple and effective construction of blast gate which shall be securely packed against leakage and in which the slide will be frictionally held in any position desired.
Objects relating to details 'and economies of construction will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.
A structure which is a preferred embodiment of my invention is fully illustrated in the accompanying drawing, forming a part of this specification, in which:
Figure I is detail sectional elevation taken on line 1-1 of Fig. II, of my improved blast gate in position.
Fig. II is a detail sectional view, somewhatienlarged, taken on line 2#2 of Fig. I, showing details of the support and the packing and support and adjusting means for the slide.
In the drawing the sectional views arc taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.
Considering the numbered parts of the drawing, 1 is a sheet metal pipe in which my improved blast gate is interposed. The blast gate support is made up of two oppositelydisposed parts or plates 2, 2 provided with flanges 3 to which the pipe lis secured by suitable screws I las illustrated. The two halves are secured together by a series of bolts 5 around the margin of the frame. Bosses 6, project beyond the faces of the plates so that the bolts clamp the same securely together, leaving a space 7 for the passage of the slide 7. Thisrpassage and support extends down into projections 2', 2 below or at one side of the pipe, as the case Speccatonof Letters Patent.

may be, forming an entrance throat for the reception of the gate. rlhe slide isprovided with a handle 8 for manipulation.
Ori-opposite sides of the gate within the entrance throat Iare supported packings 9 in suitable recesses 9, the same being fastened snugly against dialnetrically opposite sides of the slide by bars 10, which are acted upon by set screws Il, so that any desired degree of pressure can be put upon the packing material and it can be forced air tight against the opposite sides of the slide and being on diametrically opposite sides of the slide, it has little or no tendency to distort and warp the same. rIhe set screws ll for 'accomplishing this adjusting are provided with lock nuts l2 so that they may be secured leffectively in position.
I have described my improvements in the preferred form, but they may be considerably modified in detail without departing from my invention, which is defined and pointed out in the appended claims.`
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
l. In a blast gate structure, the combination of symmetricallyopposed halves, suitably spaced from each other to form a guide and support for the slide and fitted tight at their peripheries and extended to form an entrance throat, packing material in suitable recesses on diametrically opposite sides of the slide within the entrance throat, bars for urging the said packing material against the diametrically opposite sides of said slide, and suitable screws for applying pressure thereto, coacting as described for the purpose specified.
2. In a blast gate structure, a frame with guide for the slide with entrance throat therefor, packing means for said slide comprising diametrically opposed recesses within said throat, packing material in the recesses, and bars back of the material with means of compressing the same, as specified.
In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
