APPARATUS FOR COMPACTING CONCRETE OR THE LIKE.
Specification of Letters Patent.
Patented Apr. 4, 1916.
Application filed February 11, 1915. Serial No. 7,494.
To all whom it may concern Be it known that I. JOHN C. PELTQN, a citizen of the United States, residing in the city and countv of San Francisco and State of California, have invented a new and useful Apparatus for Compacting Concrete or the like, of which the following is a specification.
7 In the construction of brick. tile. slabs, etc, from concrete or the like. it is important to pack the material as closely as possible in rd er to secure the requisite strength of the article.
Broadly. an object of this invention is to I effect maximum compactness of a mass of concrete in a minimum period of time.
Another o ject is to effect j olting and displacement of the loose particales of the material by a step by step or intermittent forward movement of the table and its molds so as to simultaneously jar and advance the molds.
In the drawings I have shown two forms of apparatus by means of which my process mav be worked or accomplished.
Referring to such drawings: Figurel is a side view of an apparatus embodying'my invention; Fig.2 is a plan view of a mold; Fig. 3 is a cross section on the line w w Fig. 1'; Fig. 4 is a view similar to Fig. 3 showing the surfacing plate lowered; Fig. is a side elevation of a modified form of apparatus con tructed in accordance with my invention; Fig. 6 is a longitudinal sectional view through the apparatus of Fig. 5; Fig.
7 is a longitudinal ransverse sectional view on the line 7-7, Fig. 5; Fig. 8 is a detail view artly in section and partly in elevation illustrating the action of the cams.
1 designates a table which is supported on vertical rods 2, the lower ends of the rods being operated bv cams 3 on the shaft 4;
5 represents a. form containing the material 6 which is to be completed. This form 5 rests loosely on the table 1 there being no force to dislodge it therefrom. The form 5 as shown in Fig. 2, may be provided with a plurality or series of transverse partitions 7 to divide the material and form bricks, tiles, slabs. etc, of the desired shape or size.
If it is desired that a special finish be imparted to the surface of the bricks, tiles or slabs. there may be provided a plate 7 which is pivoted at 8 to arms 9 that are slidably mounted in brackets 10 pivoted at 11' so that the block and its supporting members may be swung out into the dotted line position indicated in Fig. 3. The under. surface of the block 7 may be covered with any suitable fabric such as cheese. cloth, gunny sacking or the like. Before removing the mold with its compacting material the block 7 is lowered against the top of the compacted material and then said block is pulledand raised to produce a certain amount of suction beneath the fa ric. The suction thus produced slightly lifts portions of the surface of the compacted material so as to somewhat roughen and change the character of said surface. If not desired the devices just described need not be used.
lVith the form of apparatus shown in Figs. 1, 2. 3 and 4 the jigging or jerking V motion relied upon to settle or pack the particles in intimate relati n and denselyis illustrated and shown. With this form of apparatus. however, it is necessary that the molds be fed in by hand and that the time such material is subjected to such jigging or jerking-motion must be timed by the operator. I have found that with most classes of concrete as short a period of time as fifteen seconds subjection to such jigging or jerking action is sufficient to completely compact or pack the mate ial. This time of course will vary to a certain degree with the amount of action given to the apparatus and it is obvious that automatic clutch means might be utilized in connection with this apparatus to stop the motion at predetermined intervals while the .moldsare re-. mo ed and fresh molds'placed thereon. i
Y A further embodiment of my invention and a preferred form thereof is illustrated in Figs. 5 to 8 where n 20 designates as an entirety the base of the machine and this base mav be made of any convenient length, width orheight as well'as of the desired or preferred structure. 22 and 23 designate suitable side members of the base and they each comprise a topbar or beam 24, a bott m baror beam 25, uprights 26 connecting the bars 24 and 25 and braces 28 arranged in pairs and connected at-their upper ends to the uprights and at the lower ends to the base bar 25. Cross bars 27 may be used to hold the side members 22 and 23 in proper spaced relation. Mounted upon this base is a plurality of cam shafts 29 which preferably extend transversely of the frame and preferably at right angles to the side members 22 and 23 and parallel with respect to one another. These cam shafts may be supported in suitable bearings 30 in 'turn secured to the under side of the top bars 241. These cam shafts may be driven in any suitable manner. In the drawings they are shown as equipped with sprocket wheels 31 over which a suitable drive chain 32 passes. As shown in the drawings between each pair of sprockets 31 there is placed an idler 33 preferably secured to an upright 26 and this idler serves to depress and tighten the chain 32 to hold it properly in contact with the sprockets 31. If desired an idler 3-1 may be secured to one of the uprights 26 to provide the proper tension to the lower limb of the chain 3:2 and hold it from compact with any obstruction. The cam shaft 35 preferably carries on one of its ends a suitable drive pulley 36 illustrated in the drawings as driven by suitable drive belt 37. It is obvious that the cam shafts instead of being driven by sprocket chains may be driven by any suitable form of gearing.
On each of the cam shafts are keyed or suitably mounted two or more cams 38 preferably formed with a plurality of cam projections 39. These cams are provided with a purpose of supporting and imparting a jigging or jerking motion to a suitable form support or table 40 which rests directly on the cams as clearly shown in Fig. 6 and which is moved forwardly and progressively along by the action of these cams against the under surface thereof. Thetable works between the top bars 24 of thebase and is prevented from moving laterally thereby but is preferably of a length suitable to support the desired number of molds or forms 41 divided into transverse compartments by suitable division plates 42. It is obvious of course that the form may be for the formation of a single brick, tile or slab, or for a number thereof of any desired form or shape. The material to form'such bricks, tiles, slabs, etc., is filled into the molds'or forms as desired, for example, after the molds or forms have been placed on the table 40 which will form a bottom for the compartments. The table is made to travel over the cams by rotating the cams through the action of the driving mechanism. As the cams are revolved one table with its mold thereon is fed along the frame. \Vhen it has reached a proper amount of progression therealong, another may be started and this Copies of this patent may be obtained for operation may be continued as long as desired. The length of the frame and the time required for the passage of the mold through the apparatus may be timed as desired with respect to the amount of compacting action required or desired with'the particular ma terial and the molds after reaching the end of the frame may be discharged onto and received by suitable convevers and by them transferred as desired. These conveyers are not shown in the drawings being common in the art.
Angle irons forming rails 44: are shown in the drawings secured to the inner sides of the top bars 24 and extending longitudinally thereof at such height as to catch the table when it is dropped by the cam surfaces 39.
From the foregoing description taken in that I provide an apparatus which will thoroughly compact the material into a very solid and condense mass within molds by giving the molds a jigging or jolting motion and that the cams which produce this motion also serve to feed the table upon which the molds are supported along so that the 1. In combination, rotatively mounted cams, a table resting on and shiftable endwise by rotation of the cams, whereby the table is jarred and advanced, and moldsresting on the table to advance therewith.
2. In combination, rotatively mounted shafts, cams fixed to the shafts, means to turn the shafts, a table resting on and shift able endwise by ro-tationof the cams, whereby the table is jarred and advanced, and molds resting on the table and traveling therewith. I a v p In testimony whereof, I'have hereunto set my hand at Los Angeles, California this 5th I day of February 1915. g p
