COIL-CLEANING DEVICE FOR REFRIGERATING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 567,969, dated September 22, 1896. Application filed July 8, 1896- serial No. 598,410. (Ilo model.)
1'0 on whom it may concern.-
Be'it known that we, CONRAD EURIOH and GEORGE DONGES, citizens of the United posits from the water which is allowed to flow over them, and these deposits prevent the heat from passing from the interior of the pipe to the water, thus rendering the apparatus ineflicient.
The object of our invention is to produce an apparatus by means of which we can quickly and thoroughly cleanse the exterior surfaces of the pipes in such cooling-coils.
The invention consists in a pair of brushes and means for holdin gthe brusheswith springpressure against adjacent tubes or pipes of the coil while they are pushed backward and forward along the coil to brush the slime and sediment from the pipes.
The invention further consists in details of construction which we will now proceed to describe, reference being had to the accom panying drawings, in which- Figure 1 is a plan view of our improved coil-cleaning device, a portion of the handle being broken away. Fig. 2 is an end view. Fig. 3 is a plan View showing the device partially folded. Fig. A is a section on the line 4 4 of Fig. 2. Fig. 5 is a section on the line 5 5 of Fig. 1, and Fig. 6 is a section on the line 6 6 of Fig. 1.
Referring to the drawings, A indicates a handle, which may be of any desired length, preferably somewhat longer than the coils upon which the device is to be used. Pivoted to the outer end of the handle are two arms B B. The arms B are, as shown, connected to a head a upon the end of the handle by hinge joints 1). These joints are constructed so that the arms may be folded inward, as shown in Fig. 3, and they are provided with shoulders I), which prevent them from being turned outward to an angle of more than ninety degrees with the handle.
Each of the brushes 0 has its bristles arranged in a semicircle, so that they will encircle one-half of a tube when applied to it. These brushes are fastened in holders D by means of set-screws d or other suitable appliances. The holders partly encircle the brushes and they are connected to plungers E by means of pivots d, which permit them to swing in the plane of the arms and handle, so that the brushes can adjust themselves to the pipes if the latter are not exactly straight and parallel. The plungers E form part of the extensible arms B and slide within the inner tubular parts Z1 of said arms. Upon the outer ends of the arms E are collars F. These collars serve as abutments for springs f, which constantly tend to press the collars and the brushes outward, and they are also connected by pivots f to braces G, said braces being pivoted at their opposite ends to a cross-head II, which slides upon the handle A. A spring-catch h or some other suitable looking device is used to lock the cross-head in the position shown in Fig. 1, thereby holding the arms B extended at right angles to the handle. At their inner ends the springs f abut against collars I, which are adjustably mounted on the tubular parts b of the arms and fastened thereon by means of set-screws or equivalent devices 1'.
Upon the inner ends of the plungers E are pins 6, which project through slots 6 and engage the collars I. The springs f constantly tend to press the collars F and the brushes outward, and the extent to which the brushes may be forced outward is limited by the position of the collar I. It will therefore be seen that the distance between the brushes may be varied by adjusting the collars I, and in all positions of the collars the brushes will be spring-pressed to the same degree.
The operation of the apparatus will be evident from the foregoing description and need only be briefly alluded to.
Our invention is designed to clean the inner sides of coils which are not accessible, so that they can be cleaned by hand by scrub-brushes. To clean such coils, the brushes can be folded, as shown in Fig. 3, and inserted between two adjacent tubes. Then by pressing the crosshead up until it is caught by the latch h the arms B will be thrown out at right angles to the handle and the brushes will be springpressed against the pipes.
If they press too strong or not strong enough against the pipes, the proper tension can be secured by adj usting the collars I. When the brushes are in position, as shown in Fig. 1, it is only necessary to push them one or more times along the pipes, by means of the handle, in order to loosen the dirt, which dirt will be carried away by the water falling over the coils. The brushes can be quickly shifted from one layer of pipes to another by folding them, as shown in Fig. 3, and then extending them again.
Having fully described our invention, What we claim, and desire to secure by Letters Patent, is-
1. In a device for cleaning coils of pipe, the combination with the handle, of arms pivoted to the handle, the outer portions of the arms being arranged to slide upon the inner portions, springs interposed between the inner and outer portions of the arms whereby the outer portions are pressed outward, brushes attached to said outer portions of the arms, and braces pivotally connected to the outer ends of the arms and to a cross-head sliding upon the handle, substantially as described.
2. In a device for cleaning coils of pipe, the combination with a handle, of a pair of arms pivoted to the handle, the brushes pivotally connected to the arms and arranged to swing in the plane of the arms and handle when the arms are extended, the cross-head sliding upon the handle, the braces connecting the cross-head with the outer ends of the arms, and means for locking the cross-head when the arms are extended, substantially as described.
3. In a device for cleaning coils of pipe, the combination with the handle, the cross-head sliding upon the handle, and the braces G, of arms for carrying the brushes, each arm consisting of a tubular part b pivoted to the handle and provided with a stop-shoulder b, a slot 6, a collaradjustably mounted on said tubular portion, a plunger sliding Within the tubular portion and provided with a stop-pin for engaging the collar, a spring arranged to press said plunger outward, and a brushholder pivoted to the outer end of the plunger, substantially as described.
In testimony whereof we affix our signatures in presence of two witnesses.

EDWARD SEIDEL, CHARLES B. GODMAN.
