APPARATUS FOR BOILER-ELITE WORK.
Application filed April 21, 1909. Serial No. 491,356.
Specification of Letters Patent.
Patented Aug. 9, 1910.
To all whom it may concern:
Be it known that I, CARL A. ANDERSON, a citizen of the United States, residing at Dubois, in the county of Clearfield and State of Pennsylvania have invented a new and useful Apparatus for Boiler-Flue Work, of which the following is a specification.
The invention relates to an apparatus for boiler flue work.
The object of the present invention is to improve the construction of apparatus for boiler flue work, and to provide a simple inexpensive and efficient apparatus of this character, equipped with means for adjustably suspending an air, or other motor in front of the flue sheet of a boiler, and capable of ready adjustment to enable flue-rolling tool, cutter, or other tool to operate at any portion of the flue sheet without changing the position of the motor with respect to the flue sheet or adjusting the hanger, which supports the motor.
With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacriflcing any of the advantages of the invention.
In the drawings :Figure 1 is an elevation, partly in section, of an apparatus, constructed in accordance with this invention and arranged for operating on the flues of a tubular boiler. Fig. 2 is a front elevation, partly in section, illustrating the construc tion of the hanger for supporting the motor. Fig. 3 is a horizontal sectional view of the hanger, illustrating the construction of the brace for preventing the sides of the hanger from spreading. Fig. 4 is a detail sectional view of the shafting. Fig. 5 is a transverse sectional view of the telescopic members of the shafting. Fig. 6 is a detail perspective view of the shaft coupling. Fig. 7 is a sectional view of the shaft coupling. Fig. 8 is an end view of the front or outer toolholding shaft.
Like numerals of reference designate cor- .sary adjustment of the parts.
responding parts in all the figures of the drawings.
The apparatus is equipped with an air mo tor 1, but an electric or other motor may be employed, as will be readily understood. The motor 1 is provided at opposite sides with pivots or trunnions 2, mounted in open bearings 3 of a hanger 4:, which is substantially wedge-shaped or inverted V-shaped, as clearly illustrated in Fig. 2 of the drawings. The hanger 4 is composed of two upwardly inclined converging sides, connected at their upper ends by an eye 5 and composed of upper and lower sections or members 6 and 7, adjustably secured together by bolts 8. The upper and lower sections form extensible sides for the hanger, and they have overlapped portions adjustably secured together bybolts 8. The upper sections 60f the sides of the hanger are provided at intervals with perforations 9 to secure the neces- The lower terminals 'of the sides of the hanger are bent upon themselves, or otherwise shaped to provide the open hook-shaped bearings 3, and the pivots or trunnions 2 are confined in the bearings by means of plates 10, bolted or otherwise secured to the sides of the hanger and having lower outwardly bent portions, partially closing the entrance openings of the bearings 3, as clearly illustrated inFig. 1 of the drawings. The sides of the hanger are prevented from spreading by a horizontally disposed brace 11, having hook-shaped terminals 12 bent inwardly on themselves, as illustrated in Fig. 3 of the drawings to embrace thesides of the hanger and engage the inclined outer edges thereof. The horizontal brace 11 is supported in position by the angular arrangement of the sides of the hanger, which prevent the brace from slipping downward.
The connecting eye 5, which is located at the apex of the hanger, is linked into an eye bolt 13 having a threaded shank and depending from a horizontally disposed supporting bar 14;, provided at intervals with perforations 15 for the reception of the eye bolt to permit the apparatus to be adjusted toward and from the flue sheet 16 of a boiler 17. The shank of the eye bolt, which passes through any of the perforations of the supporting bar, is provided with a nut, which justably mounted on the horizontal bar and engages the upper face of the same. The outer end 18 of the supporting bar is bent upward to form an attaching lug, which is secured by a screw 19, or other suitable fastening means to a portion of the boiler or the adjacent structure.
The drive shaft of the motor is provided with a socket 20 for the reception of a shank 21 of one of a pair of telescopic shaft members 22 and 23. The shaft member 22, which has a longitudinal opening, which is tubular,
is rectangular in cross section, and the other shaft member 23 is squared to fit the tubular member, but the parts may be slidably connected in any other preferred manner and may be of any other non-circular cross sec- The telescopic shaft tional configuration. members are extensible to move inward and outward a tool 24, which is detachably fitted in a socket 25 of a front tool-holding shaft 26, thus permitting the tool to be adjusted to and inserted in the several flues. This adjustment may bemade by hand or any other suitable means. The tool 24: is tapered for expanding the boiler tubes or flues,but the apparatus may be equipped with a cut ter, or any other suitable tool for operating on the boiler.
The front or tool holding shaft 26 is connected with the extensible shaft member23 by means of a coupling 27, composed of two sections, each equipped with substantially circular loops 28 and 29, arranged at right angles to each other, one of the loops being slightly smaller than and passing through the other loop. The loops 28 and 29 of each section are linked into the loops of the other section, forming a flexible connection and adapted to permit free movement or angular adjustment of the parts without looking or affecting the rotary motion communicated to the tool-holding shaft through the extensible rotary shaft members.
The motor is pivotally mounted in the hanger and is adapted to be rotated to arrange the extensible shaft members either in a horizontal position or at an upward or downward inclination, as indicated by dotted lines a and b, and the shaft members are extensible to permit the tool 2% to be moved inward and outward as occasion demands, and the tool may be arranged to operate on any portion of the flue sheet without readjusting the hanger. The eye bolt forms a pivot and permits a horizontal swinging movement, and in practice the nut will be keyed or otherwise locked on the bolt.
