HOT-STEEL SCRAPER.
Specification of Letters Patent.
Patented Sept. 19, 1916.
T 0 all whom it may concern.
Be it known that I, WILLCORD W. Corn, a citizen of the United States, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Hot- Steel Scrapers, of which the following is a specification.
My present invention relates to improvements in apparatus for scraping or cleaning metal bars, rods, and the like, and particularly for removing or cleaning the scales or crusts from hot pieces of metal.
The primary object. of the invention is to provide an apparatus of this character which is capable of receiving the bars, rods, or other pieces of hot metal with facility and is operative to effectively remove the scales I or crusts therefrom quickly and by a simple manipulation of the bar, rod, or other piece of metal:
A further object of the invention is to provide a scraperof this character which is capable of being adjusted readily to accommodate it to metal bars, rods, or other pieces of different sizes and also to adapt the apparatus to rods, bars, or other pieces having cross-sections of different shapes.
To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.
In the accompanying drawings:-
Figure 1 is a front elevation of a scraper or cleaning apparatus constructed in accordance with the present invention. Fig. 2 represents a rear elevation of the same. Fig. 3 represents a section on the line 33 Fig. 4 represents a section on theline H of Fig. 2. Fig. 5 is a view similar to Fig. 3, showing diagrammaticallythe position ofthe parts when a bar or rod isinserted therein. Fig. 6.is a detail perspective view of one of the movable scraper-blades. Fig! 7 is a detail perspective. view of one,;of theflst'uds for holding the movable scraper vbladesfin operative position. Fig.-8 is'a detail perspective view -of,a scraper bladejaw adapted to'operate upon round rodsorbars. I
Similar parts are designated by the same reference characters in the several views. In heating metal rods, bars, or other pieces n furnaces preparatory to forging the same in drop-hammers or presses, scales or crusts form on the surfaces of the bars or rods, and if the bars or rodswith the scales or crusts thereon are forged in the dies of a drop-hammer or press, such scales or crusts, which are harder than the heated metal of the bars or rods, are embedded in the surfaces of the bars or rods, rendering the forgings defective. A considerable percentage of loss in forgings results from this cause.
It is the principal object of the present invention to provide an apparatus which is capable of effectively removing these scalesor crusts when the heated bars or rods are removed from the furnace and before the same are forged in the dies, the apparatus to be so constructed that it will readily receive the heated bar or rod while the same is held at one end by tongs in the hands of the workman, and the withdrawal of the heated bar or rod will cause the apparatus to thoroughly and efiectively remove the scale or crust, the time required for the removal of the scale or crust being so short as to avoid any appreciable cooling of the metal rod or bar in the interval between the removal of the same from the furnace and capacity for which the apparatus is designed. The main plate or frame has a lower extension or leg 3 which serves to fasten or secure it to an appropriate support, the leg 3 in the present instance being bent horizontally to form a bracket 4 which may be bolted on the top of a table, bench or other support, and stiffening ribs or'webs 5 preferably extend between the leg 3 and the bracket 4 to maintain these parts in rigid relation. Arms 6, 7 and 8 radiate from the central opening 2 in the base plate. At the rear of the base plate or frame are located blades which operate to scrape the scale or crust from the rods or bars. In the construction shown, a blade 9 is fitted at the rear side of the leg 3 and hasascraper edge or jaw 10 which extends across the opening 2 in rear of the base plate. The blade 9 is preferably adjustable to enable the apparatus to accommodate bars, rods, or other metal pieces of different diameters, but when once adjusted is preferably held rigidly in its adjusted position. In the present instance, the blade 9 is provided with longitudinal slots 11, and bolts 12 are provided which extend through the slots 11 and through a slot 13 in the leg 3, each bolt having a head 14 to clamp against the rear surface of the blade 9 and a nut 15 to clamp against the forward side of the leg 3. If desired, the rear face of the blade 9 adjacent to the slots 11 may be'serrated, as shown, and the under sides of the heads 14 of the bolts may be correspondingly serrated to prevent shifting of the blade relatively to I v and mode of operation.
the bolts when the latter are tightened. To enable the scraper edge 10 of this blade to be removed for sharpening, or renewed, it is preferable to provide the scraper edge for this. blade with a separate jaw 16, this jaw being set in the upper end of the blade 9 and removably secured to the'blade 9 by screws 17 or equivalent means. At the rear sides of the arms 6, 7 and 8 are arranged slidable scraper blades 18, 19 and 20, these blades being similar in their construction Each of these blades has a scraper edge 21 which is preferably formed on a jaw '22 which is removably inserted in the inner end of the respective blade and is detachably secured thereto by-screws 23 or equivalent means to enable removal of the jaws for sharpening or replacement. Each -of these slidable jaws is also formed in the present instance with a slot 24 which extends longitudinally thereof, and a stud 25 ,isprovided which serves to guide and limit/the respective slidable blade in its movements, although'permitting rearward deflection of the blade when the bar or rod is introduced into the apparatus. Each of these studs in the construction shown has a rectangular head 26 which fits into the slot 24 of the blade, the head 26 being' of a size and shape that will permit a limited slidingv movement of the blade relatively to the stud, while the sides of the head 26 will coiiperate with the sides of the slot 24 and thereby guide the blade in its slidingmovements. In order to assist the stud in guiding these blades, lugs 27 are preferably formed on the ed es of each of the arms 6,7 and 8, these ugs being arranged at the longitudinal edges of the respective blades and thus operating toprevent lateral edgewise displacement of the blades. The head 26 of each stud clamps against the rear side of the corresponding arm 6, 7 or 8, as the case may be, and a rib 28 on the stud projects into a slot 29 in the respective arm of the frame, the stud having a threaded end 30 which extends to the front of the main plate or frame and is there provided with a nut 31 which clamps against the forward side of the base plate, drawing the under side of the head 26 against the rear side of the base plate and in that manner holding the stud firmly in fixed relation to the base plate. The slot 29 in the base plate permits the stud to be adjusted, thereby accommodating the sliding blades to bars or rods of dilferent diameters. In. order to the center of the opening 2 in the base plate,
but these sliding jaws are also capable of tilting or swinging rearwardly. To permit such movement of the slidable scraper blades, each stud has lugs 32 thereon which engage the rear side of the respective scraper blade at opposite sides of the slot 24 therein.
Means is dprovided for yieldingly pressing the oppose scraper blades toward one another and for also returning the slidable, scraper blades to their normal alined position afterhaving been deflected or swung rearwardly incident to the introduction of a rod or bar between them. In the present instance, a stud 33 is fixed to each slidable and tiltable scraper blade and also to the relatively fixed blade 9, these studs projecting rearwardly from the blades for a suitable distance, and tension springs 34 are stretched between the adjacent studs 33 in such a manner as to avoid obstructing the opening through which the rod or bar is in- 120 sorted, the springs, however, operating to perform the dual function of sliding the jaws inwardly or toward one another and of returning these jaws to alined position after having been deflected or swung rearwardly incident to the introduction of the bar or rod. As shown, the ends of the springs 34 engage the studs 33 toward the rear ends. of these studs or at points ofiset substantially to the rear of the planes of the scraper blades. In order to prevent accidental disengagement of the ends of the springs 34 from the studs, the outer ends of the studs may be curved, as shown, or a cotter pin and washer 35 may be provided on each stud to retain the ends of the springs thereon.
In practice, scraper jaws are used to conform to the cross-section of the bars, rods, or other pieces that are being handled. For example, in handlin bars or rods which are square or rectanguIar in cross-section, jaws having straight edges, as shown in Figs. 1, 2 and 6, are used, while in handling bars or rods which are round in cross-section, a jaw such as shown in Fig. 8 may be used, the jaw in this instance having a scraper edge 36 which is concaved appropriately to fit the circumference of the round rod or bar.
In using an apparatus constructed as hereinbefore described to remove scale or crust from rods or bars, the different blades are adjusted so as to provide an opening between them which is slightly less than the dimensions of.the bar or rod which is to be subjected to the scraping operation. To remove the scale or crust from the bars or rods, the same are removed from the furnace usually by tongs, and each heated rod or bar is introduced endwise through the opening 2, and the striking of the end of the bar or rod against the inner ends of the sliding and pivoted blades causes the latter to deflect or swing rearwardly, as shown diagrammatically in Fig. 5. The rod or bar is then introduced for its full length into the apparatus, and it is then pulled out of the same. In pulling the rod or bar forward, the pivoted blades which were deflected when the rod or bar was introduced into the apparatus move forward against the rear sides of the base plate, and the scraping edges on these blades are then supported firmly in position to remove the scale or crust from the bar as the latter is pulled forward.
